Advantages and disadvantages of three polishing methods for stainless steel

Commonly used polishing methods include mechanical polishing, chemical polishing, and electrochemical polishing. Each of these three methods has its own advantages and disadvantages.

1. Mechanical polishing.

The advantage is that the finished part has good leveling property and high brightness. The shortcomings are labor intensity, serious pollution, and complicated parts can not be processed, and the gloss can not be consistent, the gloss retention time is not long, boring and rusting. More suitable for processing simple, medium and small products.

2. Chemical polishing.

The advantage is that the processing equipment has less investment, the complicated parts can be thrown, the speed is fast, the efficiency is high, and the corrosion resistance is good. The disadvantage is that the brightness is poor, there is gas overflow, ventilation equipment is needed, and heating is difficult. It is suitable for processing small batches of complex parts and small parts with low brightness requirements.

Chopped Graphite/Graphite Electrode in different materials have different definition of graphite pieces, some data and literature is not very big graphite particles are called graphite pieces (such as Graphite Powder) some is graphite products have a certain size, for Graphite Broken into patches, we here say of graphite for a second, usually called graphite blocks. Graphite is produced from graphitization and machining process of graphite products. It is used as additive and conductive material in the manufacture of graphite waste in steel and foundry industries, and can also be processed according to customer's requirements. They are also widely used in electric arc furnaces (steelmaking) and electrochemical furnaces (metallurgical and chemical industries).

Main use of graphite

Graphite pieces due to its low ash content, conductive and heat conduction performance is good, so there are a wide range of USES, can be added to the formula of less ash or dust products, graphite broken broken into small particles commonly use. Ingredients to add a certain amount of graphite, the plastic paste after kneading, especially during extrusion can reduce the friction resistance paste to squeeze the mouthpiece, to improve the coefficient of pressure type. Graphite pieces of coal adsorption properties of asphalt is better, to join the carbon block can rise to reduce the "short" waste (i.e., the product after roasting top produce honeycomb structure), and can improve the thermal conductivity of the carbon block and alkali corrosion resistance. The electrode paste used in hermetically-sealed thermal furnace is added to a certain amount of graphite to increase the conductivity and thermal conductivity of the electrode paste and accelerate the sintering speed of electrode paste. When the graphite is ground into small particles or fine powder, it is also used as raw material for the production of graphite chemical equipment (such as graphite-resin tubes). The graphite can also be used as a carbon addition agent for the electric furnace.

Graphite classification

1. Raw and broken. It is a raw blank that is not qualified after molding.

2. Roasting is the cutting debris that is recovered after the roasting of raw billet and after inspection of unqualified waste and the processing of calcined products.

3. The graphite is broken, and it is inspected by the graphite-producing waste and the cutting debris produced by graphite products in the process of processing.
