Black metal industry standard of the People's Republic of China: Ultra High Power Graphite Electrode (YB/T 4090-2000) "regulation of the ultra High Power Graphite Electrode shape, size and allow deviation, technical requirements, test methods, inspection rule, packing, marking, storage, transportation and quality certificate. It is applicable to high - power Graphite Electrode, which is made of high quality needle coke as the main raw material, which is made of molding, roasting, impregnating, graphitization and machining.
Graphite is very common in nature, and graphene is the intensity of the highest substance known to mankind, but scientists could still take several years or even decades, to find a way to graphite into a large high quality graphene "thin film" method, thus they can be used to manufacture all kinds of useful material for mankind. According to scientists, graphene in addition to very strong, but also has a series of unique features, graphene or conductive performance of the best known materials, which makes it also has great potential applications in the field of microelectronics. The researchers even see graphene as a substitute for silicon that can be used to produce future supercomputers.
superiority
1: the increasing complexity of the geometry of the mould and the diversification of the product application result in the higher and higher demand for the discharge accuracy of the spark machine. The advantage of graphite electrode is that it is easy to process, high removal rate and low graphite loss. Therefore, some of the group spark machine customers have abandoned copper electrode instead of graphite electrode. In addition, some special shaped electrode can't made of copper, but easier to forming, graphite and copper electrode is heavier, not suitable for processing large electrode, these factors have caused part of the group of the graphite electrode spark machine customer applications.
2. Graphite electrode is easier to process, and the machining speed is obviously faster than that of copper electrode. For example, graphite is processed by milling process, and its processing speed is 2~3 times faster than that of other metals, and no additional manual processing is required, while the copper electrode needs to be worn by hand. Similarly, if you use a high speed graphite processing center to make the electrode, it will be faster, more efficient, and will not produce dust problems. In these processes, selecting the right tools and graphite can reduce the abrasion loss of the cutter and the breakage of the copper gong. If the concrete is the milling time of graphite electrode copper electrode and graphite electrode, graphite 67% faster than copper electrode, in the general case of electro discharge machining, the adoption of graphite electrode machining 58% faster than using copper electrode. In this way, the processing time is greatly reduced and the manufacturing costs are reduced.
3: the graphite electrode is different from the traditional copper electrode design. Many mold factory in copper electrode roughing and finishing usually have different requirements, and graphite electrode is used almost the same amount of reserve, this reduces the CAD/CAM and the frequency of machine, sheet is for this reason, to a large extent is enough to improve the precision of the mold cavity.
Of course, the first thing that should be clear is how to use graphite materials and other related factors after the copper electrode is transferred to graphite electrode. Today, some group spark machine customers use graphite for electrode discharge machining, which is exempt from the process of mold cavity polishing and chemical polishing, but still achieve the desired surface finish. If the process of time and polishing is not increased, it is impossible for the copper electrode to produce such an artifact. In addition, the graphite is divided into different levels, and in particular the application of using the appropriate level of graphite and spark discharge parameters to achieve the ideal processing effect, if in the use of graphite electrode spark machine operators use the same as the copper electrode parameters, then the result is certainly disappointing. If the material of the electrode is strictly controlled, the graphite electrode can be used in the non-loss condition (less than 1%), but the copper electrode is not used.

Analysis of Development Status of Security Technology in Financial Industry
The security system of the financial industry is a multi-angle and multi-latitude composite security technology prevention system consisting of a civil defense system, a technical defense system, a physical defense system, and a management system. The common security subsystems in technical protection systems include intrusion alarms, entrance and exit controls, voice intercom, video surveillance, etc. The following is a brief analysis of the current status of the development of these four systems.
Intrusion alarm
An obvious feature of the development of intrusion alarms in recent years has been the realization of IP-based equipment, which has evolved from analog line transmissions such as the previous single telephone line to various network transmission technologies such as Ethernet transmission and GPRS wireless transmission. At the same time, in the application to provide secondary development interface, forming a product tends to integrated development trend. From a single alarm host device to the development of intelligent alarm platform-related products, some of these manufacturers also introduced a video host with alarm function, and support for visual intrusion alarm system products.
<br> <br> access control access control system in recent years a distinctive feature also tend IP development, many manufacturers continue to introduce relevant equipment to support Ethernet transmission, but also introduces a number of new technologies such as finger vein technology, video Biometrics technology, RFID technology, smart technology, mobile internet technology, etc., make the current entrance and exit control system more intelligent, visual, and humane.
Voice intercom
The main change of the voice intercom system in recent years is that the IP voice intercom system gradually replaced the traditional analog voice system, and the video was integrated into the IP intercom to form a visual intercom system. For example: voice intercom system in self-service bank.
Video Surveillance
Video surveillance is the core of management in security monitoring and visualization, and its investment accounts for a larger share of the entire financial security products. Combined with the analysis of video surveillance development in recent years, it can be summarized as: "high-definition," "networking," and "intelligent." High-definition refers to the rapid application of high-definition front-end and back-end devices, and the use of network-based devices such as IPC, NVR, and decoding devices for network surveillance is rapidly increasing, while smart refers to the gradual increase in the use of video devices. Development, more and more intelligent video surveillance equipment.
After analyzing the status quo of the above four security subsystems, we will find a common characteristic that the development of each subsystem will focus on "networking" and "visualization", and this is also the characteristic point of the development of the financial security industry at this stage.
In addition, another characteristic of the development of financial security technology is that the construction of networking platforms and monitoring centers has entered an active period. State-owned banks, joint-stock banks, and regional banks selected the networking platform and continued to build the entire network. In this process, there are several important features: the basic application of video alarm network, the deep integration of security subsystems and the deep integration of security and business management; and it is in line with GB/T28181 "security video surveillance network system information transmission Technical requirements for exchange, control, and national standards.
Security Industry Security Technology Outlook
The security industry has developed extremely rapidly in recent years. One of the important support points is the rapid development of security technology, which continues to promote the rapid development of the industry. In the next few years, what are the trends in the development of security technologies in the financial industry? Which technologies will promote the development of the financial security industry? Basically summarized in the following terms: “H.265â€, “Internet HDâ€, “ "Intelligent", "big data", "business integration", "smart bank", and a brief analysis of these technological trends:
Financial Security Development Trends - H.265
At present, H.265 is extremely hot, and various manufacturers have successively launched the H.265 product series. Taking Hikvision as an example, it has introduced multiple models and multiple series, from the front end to the back end, to transmission, Decode to show the full system product model. Why is the heat of H.265 so high? What is behind this fiery?
After security goes into high definition, the H.264 video compression standard has been overwhelmed by higher pressure. H.264 is optimized and improved, but it still feels a bit difficult. H.265 brings the feeling to the security industry that it is "enhanced coding efficiency. Times, H.265 encoded video stream size compared with H.264 in the test, can be reduced by about 39-44%, of course, different test methods may still have some deviations in the data. Taking 1080p full real time as an example, only about 1.5~2M bit rate is required. Therefore, H.265 has an absolute advantage over H.264 in terms of performance. H.265 can effectively reduce storage costs and space, make ultra-high-definition video surveillance a reality, making high-definition 4G smooth transmission also become a reality. At the same time, multi-core processors have also become mainstream in the market, which means that the hardware performance of H.265 is also available. It can be seen that H.265 is the development direction of the future high-definition, and it can even be said that the era of H.265 has come.
Financial security trends - focusing on high-definition network point <br> <br> this trend is that the "network", not in "high definition." With high-resolution and wider monitoring horizons, the equipment has better economic applicability, and HD surveillance has become a trend recognized by financial security. There is no dispute. In the era of security industry entering the IP era, the financial industry as the industry with the largest scale of security applications, will naturally follow this trend, the representative of the network HD is the IPC and NVR. At present, there are many analog HD products on the market, which are only transitional products in one stage and will eventually be replaced by high-definition network. At the same time, with the improvement of the computing performance of the camera chip and the upgrading of the coding technology, the delay issues, transmission bandwidth issues, and storage space issues faced before the high-definition network have all been solved by related technologies.
Financial Security Development Trends - Intelligent
The high-definition of surveillance video has laid a good foundation for the industry's intelligence, and intelligent analysis continues to deeply apply the financial security industry. The future intelligent technologies will focus on the characteristics of “pre-positioned†and “systematizedâ€, that is, intelligent analysis and calculation. From the background service analysis to the front-end equipment self-analysis, the real smart application will be the integrated intelligence of the front end, back end, platform, and transmission.
Hikvision, a leading security company, proposed the concept of "Smart" micro-intelligence - that is, "every IPC is transformed from an image and sound acquisition unit to a smart processing unit." Smart back-end and Smart networking platform emerged again, which formed a smart system - "Smart system". Through "Wisdom cloth", "Intelligence prevention", "Intelligence search" and "Intelligent intelligence", it is possible to construct a three-dimensional system. System-level intelligent monitoring system. The future financial security products must be products with intelligent functions. In other words, the "Smart function" will become the standard equipment.
Financial Security Development Trends - Business Integration
With higher and higher requirements for financial security management, it is not only necessary to meet the functions of security protection, but also to meet the needs of various financial institutions daily management business management. For example, remote inspections of business orders at various business outlets, remote supervision of staff, post-authentication and processing of customer complaints, and seamless integration of audio and video data and business management systems for related business management. That is, the network platform software is required to have a deep integration with the financial service system. For example, it supports online logos for real-time events, support for the management of multimedia archives, support for digital video encryption, support for dedicated departments and individual monitoring groups, and support for audio and video data segment management. Recently, the China Banking Regulatory Commission (CBRC) has issued a document requesting a complete video and audio capture video of the financial product trading behavior. It requires that the audio and video data provided by the security system be used as data support for the banking business system.
Based on the business management needs of financial users, the security system is deeply integrated with the business management system. Video resources are provided as tools for business managers to seamlessly integrate the financial security system with the business system.
Financial security trends - big data <br> <br> cloud computing, cloud storage technology has been successfully applied in the financial security industry, such as "private cloud platform" project gradually increased in the bank building project monitoring, treasury project, the cloud Technology is no longer a castle in the air. With the massive data convergence brought about by the gradual realization of the whole network, the business needs of the integration of security systems and business systems are continuously highlighted, and the security management level requirements are continuously improved. At the same time, the video structuring technology gradually matures, and big data applications will emerge. The financial security industry has gradually emerged. That is, the emergence of the application will help financial industry management decisions from the "experience-dependent" to "data-based", the effective use of the final data will give birth to a lot of new intelligent applications on the financial industry.
Financial security trends - Power wisdom Bank <br> <br> wisdom Bank is the advanced stage of traditional banking, online banking, many domestic banks to create their own by improving the characteristic, function and diversity and other "wisdom Bank's service model. It is mainly through scientific and technical means and humanized service methods to achieve a good human-computer interaction experience. Under the background of the construction of smart banks, financial security companies can provide support in visualization technology, biometrics technology, voice technology, large-screen display technology, intelligent analysis technology, RFID wireless radio frequency technology, and help the financial industry to reach the stage of smart banking.
Summary <br> <br> With the growing popularity of science and technology and the deepening of financial security management requirements, future financial security will develop advanced technology from both application and data integration to the construction plan. In terms of advanced technologies, high-definition, intelligence, and networking will be the core technical support for future financial security development. At the same time, data sharing, smart mining, and big data implementation on the other hand will require more information and data sharing, interconnection, and system service integration. Only under the effective combination of advanced technology and effective support of data interconnection and sharing, can the financial security industry create more economic value and ultimately realize the continued prosperity and development of the entire financial security industry.
