The electric furnace is also called the electric arc furnace, which is the steel making equipment that the electric arc between the electric extreme part and the furnace material as the heat source. It is mainly used to smelt waste steel. The steel type and process equipment, furnace size of electric furnace determine its internal structure, the electric furnace generally is made by furnace top, furnace wall, furnace bottom and tapping trough,Today we will talk about the prefabricated refractory used in the top of the electric furnace for your reference.
The prefabricated refractory used in the top of the electric furnace is made of molten corundum and Chromium oxide refractory as aggregate, which is mixed with binding agent and additives,after mixing,casting to the precast mold to formed,then baking in the baking room after drying.
