Special graphite for electric spark processing

Electric spark processing is a new type of processing process in the mechanical manufacturing industry. Electric spark processing can process many metals with large hardness and can be processed. Copper materials can also use graphite materials. Graphite materials used for electrical electrodes used for electrical sparks must have the following conditions:(1) The structure is dense and uniform in tissue, and there should be no coarse particles and large pores;(2) There is a high mechanical strength and good processing performance. It can process complex shapes or sharp corners and thin slices;(3) Graphite tool electrodes, there are certain losses during the processing of electricity, this loss should be as low as possible;(4) The discharge characteristics are stable and the processing speed is fast. Therefore, graphite machining is generally used with graphite structure graphite or exquisite particle structure graphite. It is best to have the same sex in physical properties. Therefore

Introduction to Graphite Carbon Products

1. Used as refractory material: Graphite and its products have properties of high temperature resistance and strength, and are mainly used in the metallurgical industry to manufacture graphite crucibles. In steelmaking, graphite is commonly used as a protective agent for steel ingots and as a lining for metallurgical furnaces.2. As a conductive material: used in the electrical industry to manufacture electrodes, brushes, carbon rods, carbon tubes, positive electrodes for mercury positive current transformers, graphite gaskets, telephone parts, coatings for television tubes, etc.3. As a wear-resistant lubricating material: Graphite is often used as a lubricant in the mechanical industry. Lubricating oil often cannot be used under high-speed, high-temperature, and high-pressure conditions, while graphite wear-resistant materials can work without lubricating oil at high sliding speeds at temperatures of 200-2000 ℃. Many devices that transport corrosive media are widely made of graphite m

The difference between graphite and coal

There are differences between graphite and coal in the following four aspects:Composition and structure: Graphite is composed of carbon elements, and its structure is composed of face centered cubic crystal structures. Carbon atoms are connected by strong covalent bonds. Coal, on the other hand, is mainly composed of alkyl groups and aromatic rings, with alkyl groups containing more hydrogen elements.Physical properties: Graphite has excellent conductivity, which is comparable to metals such as copper and silver. Coal, on the other hand, is a type of sedimentary rock containing carbon, which has the characteristics of providing thermal and chemical energy.Usage: Graphite is widely used in the manufacturing of pencil leads, electrodes, refrigerants, ships, anti-corrosion coatings, and lithium batteries due to its conductivity and other excellent properties. Coal, on the other hand, is mostly used as a biofuel and is widely used in fields such as power generation, barbecue, and water he
