The applications of graphite in the metallurgical industry

 

What are the applications of graphite in the metallurgical industry?

 

1. Electrolytic cell cathode material: Graphite has the characteristics of high volume density, good electrical conductivity, high temperature resistance and corrosion resistance, and is widely used in electrolytic cell cathode blocks, such as cathodes for hydrolysis of aluminum.
2. Electrode plate filler: Graphite can improve the conductivity and mechanical strength of the electrode, and is often used as a filler for various electrode plates, such as aluminum electrolytic cell electrode plates, sodium material electrode plates, etc.
3. Furnace lining and refractory materials: Graphite has good high temperature resistance and can be used for linings or insulation and protective layers of various metallurgical furnaces, such as blast furnace skins, converter linings, electric furnace top covers, etc.
4. Flame retardant: Graphite itself is difficult to burn, and can be used as a flame retardant for various polymers and rubbers. It is widely used in metallurgical equipment such as conveyor belts and hose sleeves.
5. Sand molds and cores: Graphite has certain mechanical strength and good resistance to high temperature and casting, and can be used for sand molds and cores in various casting processes.
6. Friction and brake materials: Graphite has a low and stable friction coefficient and is often used in sliding bearings, motor brushes, brake pads, clutch plates, etc. of metallurgical equipment to reduce friction and vibration.
7. Ilmenite reducing agent: Graphite can be used as a reducing agent for ilmenite at high temperatures and used in titanium dioxide production, which is also one of the important applications of graphite in the metallurgical industry.

In addition to the above applications, graphite is also widely used in heat treatment furnaces, vacuum furnace linings, casting embossing dies and brushes in the metallurgical industry, showing great potential and prospects in the metallurgical field.

The applications of graphite in the metallurgical industry

 

Graphite electrodes are mainly used in metallurgy, chemical industry and other industries, among which electric furnace steelmaking is the largest user of graphite electrodes. Electric furnace steelmaking uses graphite electrodes to introduce current into the furnace, and uses the high-temperature heat source generated by the arc between the electrode end and the charge to smelt.

 

The application of graphite in the metallurgical industry not only improves production efficiency, but also promotes the advancement of industry technology. Especially in the field of metallurgy, graphite electrodes are key materials, and their quality and performance are crucial to steel production.
