cupola furnace slag aerated block stainless steel

Jan 01, 1982· Iron foundries using the cupola furnace in which pig iron, steel and fluxes are melted, produce cupola slag as a by-product. In Nigeria, many iron foundry activities are presently springing up in anticipation of the takeoff of the iron and steel industries being built by the government via the blast furnace and direct reduction routes.
