摘要 |
<p>Process for the production of liquid steel, according to which melting of ferrous substances rich in carbonaceous substances is carried out so as to obtain a carbide-containing liquid metal and then decarbonisation of the said liquid metal is carried out so as to convert it into liquid steel, characterised in that melting of the said ferrous substances is carried out in a first vessel (1) of an electrical furnace, a pretreatment of the said carbide-containing liquid metal thus obtained is then carried out in a separate pretreatment plant, and, finally, decarbonisation of the said carbide-containing liquid metal is carried out in a second vessel (10) of an electrical furnace. Another subject of the invention is a plant for the production of liquid steel for making use of this process. The first and second vessels preferably consist of the two vessels of a double-vessel electrical furnace with single electrical supply. <IMAGE></p> |
