Abstract Nine high carbon chromium bearing steel ingots melted and teemed bydifferent processes have been sectioned longitudinally and their macrostructureincluding distribution of non-metallic inclusions and carbides as well as gascontent, etc. have been examined. Ingots made by electroslage refining and so-lidifying in water cooling crystallizer showed better quality than those made bythe conventional process, especially for slabs or ingots with smaller cross-sections. High temperature diffusion annealing treatments promote the refinementof the macrostructure of ingots. Vacuum melting and teeming are very effectivefor the improvement of the quality of ingots.
