Abstract
본 발명은 반응기, 예를들면 전로(10)에 있는 용융조에서 농축물 또는 예비환원된 농축물을 용융환원시키므로서 철을 제조하는 방법 및 장치에 관한 것이다. 농축물 및 탄소성 환원제는 용융철 층(28) 및 그 위의 슬래그층(30)으로 이루어진 용융조에 공급된다. 고온 공기와 같은 산소함유개스는 배출되는 환원개스를 연소시켜 용융조를 가열시키기 위하여 슬래그층을 향하여 후-연소구역(37)으로 취관(38)에 의해 송풍된다. 연소공정에서 생성된 고온 배기개스는 반응기의 지봉에 있는 배출구(21)를 통하여 빠져나간다. 산소함유 개스는 후-연소구역으로 송풍되는데 이 구역은 송풍시에 슬래그 및 금속파편들이 튀어서 개스상에서 반응기의 냉각벽(11)에 도달하는 것을 방지하도록 냉각판넬(42)에 의해 반응기의 벽으로부터 보호된다.The present invention relates to a method and apparatus for producing iron by melt reduction of concentrates or pre-reduced concentrates in a reactor, for example a melting bath in converter 10. The concentrate and carbonaceous reducing agent are fed to a molten bath consisting of a molten iron layer 28 and a slag layer 30 thereon. Oxygen-containing gas, such as hot air, is blown by the duct 38 into the post-combustion zone 37 toward the slag layer to burn the discharged reducing gas to heat the molten bath. The hot exhaust gas produced in the combustion process exits through an outlet 21 in the reactor rod. The oxygen-containing gas is blown into the post-combustion zone, which is protected from the walls of the reactor by the cooling panel 42 to prevent slag and metal debris from splashing and reaching the reactor's cooling wall 11 on the gas during the blowing. do.
