Graphite Block

What Is Graphite Block

Graphite Carbon Block is a kind of carbonaceous refractory material made from coke, anthracite or graphite, and tar as raw materials after being mixed and shaped, and burned to 1450℃ in reducing flame. The carbon mass fraction is 88% to 90%. It can resist the erosion of molten metal and various slag, but it is easy to be oxidized. It’s used for masonry bottom and hearth of blast furnace.

Main Applications

Graphite Carbon Blocks are not only widely used in the metallurgical industry, but also in aluminum electrolytic cells. In addition, it is widely used in pickling tanks and electroplating tanks in the electroplating industry, dissolution tanks in the paper industry, reaction tanks, and storage tanks in the chemical industry, furnaces (or equipment lining) in the ferroalloy industry, and smelting non-ferrous metals (such as aluminum and lead), Tin, etc.). Scope of application: metallurgical industry, chemical industry.

Using Guide


Graphite Carbon Block has good thermal stability, small coefficient of thermal expansion, high-temperature resistance, resistance to various acids, alkalis, salts, and organic solvents, but it is easily oxidized in an oxidizing atmosphere.
