It is one of the effective ways of smelting the low silicon pig iron to increase the cleanliness degree of steel and to decrease the cost of iron and steal.
随着钢铁工业生产的进步，特别是洁净钢生产技术的发展，炼铁和炼钢生产均对生铁含硅量提出了越来越高的要求，而冶炼低硅生铁是降低钢铁成本，提高钢水洁净度的有效措施之一。
By enhancing the materials and fuels quality,using high air temperature, high top pressure, high smelting strength and large coal injection, improving the metallurgical property of slag,strengthening the management and modifying operations, the low silicon smelting of BF is up to the highest level of history.
天铁2×700m3高炉通过提高原燃料质量,采用高风温、高顶压、高冶强、大喷煤,改善炉渣冶金性能,加强管理及改进操作等手段,低硅冶炼水平达到了历史新高,生铁含硅量降至0。
Decreasing silicon content in hot metal is not only the develop- ment of blast furnace processing,but also the inevitable requirement of modern steelmaking processing,in this pa- per,origin and reduction of silicon in the blast furnace are analyzed,present state of low silicon in home and outside is generalized and the methods of low silicon smelting.
