Electric arc furnace high alumina refractory castable

Short Description:

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.
