摘要

1. METHOD OF STEEL EXTRAWNING WITH PRELIMINARY HEATING OF SCRAP IN APPLICAWEALWORGHRWEQWEALWORGHRTSAWEURSEURCLEWAREHEADTMEURCLEEURCLEFURCLE TURNEFURCLEFLEURTLE CLEAR folder, pouring in iron and further melting of the melt with a gaseous oxidant; the use of coolant, before the start of the purge in the converter is introduced. Slag in the form of a melt in the amount of 25-100% by weight of scrap. 2. The method according to claim 1, distinguishes itself from the fact that slag of steelmaking, for example, converter, is introduced as slag melt. 3. The method according to claim 1, is distinguished by the fact that blast furnace slag is introduced into the converter as slag melt. 4. The method according to claim 1, of which there are two, so that the slag of the ferroalloy production is introduced into the converter as the slag melt.
