EAF Linings

The manner in which an EAF is  operated dictates both the selection of materials and constructional design of the furnace. Increasingly, the fuction of an EAF is to be an efficient melting unit with the secondary steelmaking taking place elsewhere, however, there are still furnaces that carry out significant steelmaking in the furnace itself.
Whatever the case may be, Vesuvius have a full range of refractories to provide steel makers with a furnace lining that has high longevity.Vesuvius have an extensive range of magnesia carbon products for EAF side wall application. Incorporating a range of magnesia’s from from 95% MgO sinter to 98% MgO ultra large crystal fused magnesia.
