What are the common uses of graphite?
As a conductive material of graphite in the electrical industry widely used as electrode, brush, carbon, carbon nanotubes, mercury rectifier cathode, graphite gasket, telephone parts, TV tube coating etc.. The most widely application of graphite electrode in smelting, alloy steel, iron alloy, graphite electrode, the strong current through the melting zone, the arc electrode into the electric furnace, the electrical energy into heat, the temperature rises to 2000 degrees, so as to achieve the purpose of melting or reaction. In addition, in the electrolysis of metal, magnesium, aluminum and sodium, the anode of the electrolytic cell is also made of graphite electrode. The resistance furnace for carborundum is also made of graphite electrode as furnace head conducting material.
As a wear-resistant and lubricating material, graphite is often used as a lubricant in the mechanical industry. Lubricants can not be used in high speed, high temperature, high pressure conditions, and graphite wear-resistant materials can be at -200 - 2000 temperature, and at a high sliding speed, without lubricating oil work. Many transporting corrosive media devices are widely used, which is made of graphite material piston ring, the sealing ring and the bearing, they are running, without adding lubricating oil, graphite and many metal processing (drawing, drawing) the good lubricant.
Because graphite has many excellent properties, it has been widely used in metallurgy, mechanical, electrical, chemical, textile, national defense and other industrial sectors.
Steelmaking, graphite and other impurity materials can be used as carbon agents in steel making industry. Carburizing uses a wide range of carbonaceous materials, including synthetic graphite, petroleum coke, metallurgical coke, and natural graphite. Worldwide, the use of graphite for carburizing is still one of the main uses of earth like graphite.
As one of the main uses of refractory graphite is the production of refractory materials, including refractory brick, crucible continuous casting, casting mold, mold powder, detergent and high temperature resistant materials by graphite crucible and crucible forming manufacturing related products and refractory and related products, such as crucible, retort, plug head and nozzle etc., has high fire resistance, low thermal expansion, metal smelting process, by metal infiltration and erosion are stable under high temperature, good thermal shock resistance and excellent thermal conductivity, so the graphite crucible and its related products are widely used in the process of direct molten metal.
