Document Type and Number:
WIPO Patent Application WO/1991/009143
Kind Code:
A1
Abstract:
The proposed method consists in that in the course of steel smelting the oxygen is supplied in a quantity allowing a melt to be obtained with a temperature 5 to 50 degrees above that of the steel to be smelted. As a reducing agent, materials containing carbon and aluminium are used in quantities corresponding to the ratio between the carbon of the carbon containing material and the aluminium of the aluminium containing material, equal to 1:(1-3) respectively, and a mixture of an inert and natural gas is blown through the melt from the bottom. The present invention may be used, in particular, for the production of manganese steel.
