Applications

Electric arc furnaces: Graphite electrodes are used in electric arc furnaces to melt the raw materials used to make refractory materials, for example, alumina and magnesia. The electric arc furnace use them to generate heat and melt the raw material and boost the chemical reaction.

Sintering furnaces: They are also used in sintering furnaces to heat and harden refractory materials. The sintering furnace use them to produce heat and maintain a controlled temperature to ensure the refractory material is sintered as needed.

Production of carbon-containing refractory materials: They are used to produce carbon-containing refractory materials, for instance, graphite crucibles and carbon blocks. They are used to yield heat, melt raw materials and help chemical reaction to yield carbon-containing refractory material.
