- Abstract
The article analyzes samples of chamotte refractory after service in the shaft and in the crucible of a coke gas cupola furnace during melting of cast iron with spheroidal graphite using carbon waste from the electrolysis production of aluminum as a reducing agent. It was established that the products acquire a pronounced zonal nature in service. After service in a shaft, products have a complex compaction property associated with the depth of penetration of volatile components of the charge. After service in the crucible of a coke gas cupola furnace, refractories contain a melted crust of the working zone formed in contact with the cast iron melt; working zone formed as a result of impregnation of cast iron and/or slag with melt; the least changed transition and impregnated (weakly metamorphosed) zones which structure differs little from the structure of the original refractory.
