ABSTRACT:
A method for steelmaking with direct current in which, during melting in an arc furnace, the contact anodes are connected by contact to the iron material, and the electric arc is formed between the latter and the movable cathodes. After the contact anodes attain the slag, the further burning of the electric arc between the molten metal and the movable cathodes is effected so that the working ends of the contact anodes remain immersed in the slag.
