摘要:
PURPOSE:To utilize effectively much Fe and Ca contained in converter slag and the heat energy of the slag by bringing molten iron discharged from a blast furnace into contact with the converter slag in the form of molten or hot slag in a mixer before the molten iron is charged into a refining furnace. CONSTITUTION:Molten iron discharged from a blast furnace and desiliconized optionally in a spout is pretreated before it is charged into a refining furnace. The pretreatment is carried out by bringing the molten iron into contact with converter slag in the form of molten or hot slag in a mixer. For example, the converter slag is added at the lower part of a spout extended from the blast furnace. The amount of the converter slag added is 5-100kg, especially, 1-50kg per 1ton molten iron.
摘要(中):
目的:通过在高炉内排出的铁水与熔炉或热渣形式的转炉渣接触,在混合机中,在铁水之前,有效利用转炉炉渣中含有的Fe和Ca以及炉渣的热能 装入精炼炉。 构成:将从高炉排出并在任选地喷出的脱硅剂的熔融铁在装入精炼炉之前进行预处理。 预处理是通过在混合器中使熔融的铁与熔渣或热渣形式的转炉炉渣接触来进行的。 例如,在从高炉延伸的喷口的下部加入转炉炉渣。 加入的转炉渣量为5-100kg,特别是每1ton铁水1-50kg。
