<p>The invention relates to ferrous metallurgy and more particularly to the design of a multichambered steelmaking apparatus and to the method of steelmaking using this apparatus. The invention enables the yield of steelmaking process to be increased, along with the strength of the apparatus and the output of ready product; it offers new technological features and reduces smelting time. The multichambered steelmaking apparatus of the invention contains smelting chambers communicating with each other through their upper portions; each chamber has a roof, a hearth, a process port, an outlet, oxygen supply nozzles which are preferably installed in the roof and a gas exhaust system. Gas-oxygen burners are installed on the walls of the smelting chambers facing each other. The smelting chambers can rotate about their horizontal axis. During the loading of liquid pig iron and of metal scrap, of lime and/or of limestone used as a flux, the smelting chambers are tilted in a direction opposite to the input port. During the intermediary removal of the slag that forms in the course of the oxygen blow, the smelting chambers are tilted in the direction of the input port. During the pouring of steel, they are tilted in the direction of the outlet.</p> |
