Iron sponge, containing at least 0.5% carbon, is preheated with an oxidizing gas as the gas flows in a direction traverse to the direction of the sponge, without combustion of the iron sponge.

Process for feeding iron sponge into an electric arc furnace

A bottom outlet or discharge for metallurgical vessels includes a sleeve brick, a nozzle brick positioned in the sleeve brick, the nozzle brick having therethrough a discharge opening, and a highly wear-resistant tubular sleeve fitted within the discharge opening of the nozzle brick. The sleeve brick, the nozzle brick and the sleeve are formed of materials such that they have thermal expansions at 1400.degree. C. of from 1.0 to 1.15%, from 0.5 to 0.8% and from 1.1 to 1.25%, respectively.
