摘　　要：　本文通过比较河南分公司和中州分公司的烧结法粗液脱硅流程的改进经验,提出了山西分公司烧结法粗液脱硅流程的改进方案,对粗液进行常压预脱硅,达到了降低脱硅机组压力,减少脱硅机组结垢,降低蒸汽消耗的目的。On the basis of contrasting between Henan Branch experience and Zhonzhou Branch experience, this paper put forward Shanxi Branch experiance of crude liquor desiliconizing plan. The plan applied desiliconizing under common pressure, decreasing unit scabbing and lower steam consumption.
