苏州钢铁厂于一九七四年五、六、七月份使用了平均含硫量为2.10%(最高达2.99%)的高硫焦原料条件下,炼出了合格率达98%(七月份达100%)的生铁,平均焦比700公斤左右,取得了较好的成绩。在高炉冶炼过程中,影响脱硫的因素是多方面的。而在一定的条件下,其中必有某个因素起主导作用。本着这个目的,我们采用了冶炼时间较长的1号炉(84米~3),在五、六、七月份高硫焦冶炼阶 At a high sulfur coke feedstock with average sulfur content of 2.10% (up to 2.99%) in July, July and July, Suzhou Steel Plant refined a pass rate of 98% (July 100%) of pig iron, the average coke ratio of about 700 kg, and achieved good results. In the blast furnace smelting process, the factors that affect the desulfurization are many. And under certain conditions, there must be a factor that plays a leading role. In this purpose, we use a furnace smelting a long time (84 m ~ 3), in May, June and July high-sulfur cokemaking steps
