Abstract
A method of refining molten pig iron containing phosphorus, with oxygen, to obtain steel in a rotary kiln with a basic lining, characterized because during a first period of the process refining is carried out only to such an extent that the carbon content is still at less than 0.5% while the furnace is rotated and the gaseous oxygen is supplied in such a way as to obtain a fluid slag with low iron content, and this slag is removed in whole or in part, after which it is added new slag constituents and the blowing action is continued, possibly with one or more slag extractions until the desired carbon content is obtained.
