Development and investigation of electroslag continuous casting

The principle and technological design of electroslag continuous casting (ESCC), including bifilar mode, T-shaped mould, and metal level detecting system, are detailed. Remelting was carried out for 1Cr18Ni9Ti stainless steel with ESCC. The surface finish, chemical composition, macro- and microstructures, and inclusions of the remelted billets were characterized. ESCC reduces the cost and increases the productivity in comparison to traditional ESR, while achieves comparably excellent products.
