What are the functions of graphite equipment materials?

Graphite equipment is mainly made of graphite material. To understand the knowledge of graphite equipment, it is necessary to understand the functions of graphite materials. Here, we will specifically introduce the functions of graphite materials?

1. Used as a wear-resistant lubricating material: Graphite is often used as a lubricant in the mechanical industry. As we all know, lubricating oil cannot be used under high-speed, high temperature, and high pressure conditions. However, graphite wear-resistant materials can work at high sliding speeds at temperatures of 200, 2000 ° C without the need for lubricating oil. Many equipment that transports corrosive media widely use graphite materials to make piston cups, seals, and bearings.

2. Used as a conductive material: Graphite is used in the electrical industry to manufacture electric brushes, carbon rods, carbon tubes, graphite gaskets, telephone parts, coatings for television tubes, etc.

3. Used as refractory material: Graphite and its products have the properties of high temperature resistance and high strength. They are mainly used in the metallurgical industry to manufacture graphite crucibles. Graphite is commonly used as a protective agent for steel ingots and as an inner lining for gold treatment furnaces in steelmaking.

4. Used as pencil lead, pigment, polishing agent, etc.: After special processing, graphite can be used to make various special materials for relevant industrial sectors.

5. Used as a casting, sanding, molding, and high-temperature metallurgical material: Due to the small thermal expansion coefficient of graphite and its ability to withstand rapid cooling and heating changes, it can be used as a mold for glassware. After using graphite, black metal castings are obtained with accurate dimensions, smooth surfaces, and high yield of finished products. It can be used without processing or with slight processing, thus saving a lot of metal.
