Abstract
Спосіб виробництва сталі в агрегатах рідкофазного відновлення заліза включає термічний вплив на залізорудну сировину. Залізорудну сировину завантажують разом з вугіллям і добавками в плавильно-відновлювальний реактор-газифікатор, де під дією високої температури піддають відновленню. При цьому відновлення руди і навуглецювання металу здійснюють у шарі вугілля. Після цього навуглецьоване залізо розплавляють і подають через шар вугілля і шлаку, потім утворений в плавильному реакторі шлак видаляють з робочого об'єму, чавун обробляється струменями кисню спрямованими на шар металу через додаткові фурми, і призводять його обезвуглецювання і перетворення в сталь.The method of production of steel in the units of liquid-phase iron recovery involves a thermal effect on iron ore. Iron ore is loaded together with coal and additives into a smelting reactor-gasifier, where under the action of high temperature is subjected to recovery. The recovery of the ore and carbonization of the metal is carried out in the coal layer. Then the carbonized iron is melted and fed through a layer of coal and slag, then the slag formed in the melting reactor is removed from the working volume, the iron is treated with oxygen jets directed to the metal layer through additional tuyere, and lead to its decarburization and conversion to steel.
