The role of graphite: it can be used as an anti-wear agent and lubricant. High-purity graphite is used as a neutron moderator in atomic reactors. It can also be used to make crucibles, electrodes, brushes, dry batteries, graphite fibers, heat exchangers, and coolers. , Electric arc furnace, arc lamp, pencil refill, etc.

In the iron and steel industry, graphite refractories are used for refractory linings of electric arc blast furnaces and oxygen converters, ladle refractory linings, etc.; graphite refractories are mainly integral casting materials, magnesia carbon bricks and aluminum graphite refractories. Graphite is also used as a film-forming material for powder metallurgy and metal casting. Graphite powder is added to molten steel to increase the carbon content of steel, so that high-carbon steel has many excellent properties.
