Steel melted in the normal way can be remelted in the VAR (vacuum arc remelting) furnace to produce a steel with a low content of non-metallic inclusions. For special steels, required in smaller quantities, we melt in a 10 tonne HF (high frequency) furnace. In continuous casting, the steel passes from the tundish through ceramic tubes to three water-cooled copper moulds where it starts to solidify. Finally, the ladle is lifted up to the casting platform to be cast as ingots or as continuously cast blooms. The steel is then transported to the ladle furnace where the inclusions can be modified. After melting in a 75 tonne electric arc furnace, steel is tapped into a ladle and transferred to the AOD (argon oxygen decarburization) converter, where the principal metallurgical process is performed.
