根据硅在高炉内还原机理，太钢5号高炉通过采用精料，控制煤气流和炉体热负荷分布，加强炉况趋势判断等措施，降低了焦比和燃料比。同时，成功实现了稳硅低硅冶炼，月均生铁硅质量分数达到0．35%～0．45％，炉况稳定性和各项技术经济指标均得到提高。
Based on the mechanism of silicon reduction in blast furnace, a series of measures were taken on No. 5 BF of T1SCO. They include: supplying beneficiated burden, controlling top gas distribution and heat load distribution of furnace body, reinforcing the judgment of furnace conditions, etc. As a result, the coke rate and fuel rate were reduced remarkably. Moreover, low silicon hot metal smelting was realized. Monthly average silicon content in hot metal reduced to 0.35%- 0.45%, stable operation and higher techno-economic indexes of No. 5 BF were reached.
