ABSTRACT:
In the operation of mills for the production of steel from molten pig iron and solid ferrous carriers, it is sought for economic reasons to increase the portion of solid ferrous carriers. To supply thermal carriers, such as fossile fuels, as is known, involves the disadvantages of extended charging times and of undesired accompanying elements introduced into the process.
To avoid these disadvantages, the invention provides for a combination of at least one steel converter with a direct reduction plant, a meltdown gasifier and a cupola. Therein, sponge iron discharged from the direct reduction plant is melted to pig iron in the meltdown gasifier, on the one hand, and is used as solid charge for the converter. Scrap, together with coke, is melted in the cupola to blown metal, the latter, together with the pig iron produced in the meltdown gasifier, being supplied to the converter as liquid charge.
