STEEL PRODUCTION UNIT Russian patent published in 2015 - IPC C21C5/52 

FIELD: metallurgy.

SUBSTANCE: this invention relates to metallurgy, in particular to steel production unit and method of continuous or, at least, cyclic steel production in this unit, in which the following stages are used: charging materials are melted continuously or at least cyclic on the electron-arc furnace, including ground pieces of steel crap, ground in grinding system of rejected iron and/or steel scrap, direct-reduced and/or hot preformed iron, continuously or at least without stops during melting process are loaded in the electron-arc furnace using transportation means; part of liquid steel continuously or periodically is unloaded from the liquid steel bath of the electron-arc furnace; from the thermal power of the hot exhaust gases from top of the electron-arc furnace continuously or at least during melting cycle the electric power is generated; using power generating means the grinding system connected to the electron-arc furnace for grinding of the rejected iron and/or steel scrap are power supplied continuously or at least during melting cycle using power generated from the hot exhaust gases from the furnace top.

EFFECT: invention use ensures the productivity increasing of the steel production unit.
