把降硅作为春钢铁前工作的核心内容

Si-Lowering: A Key Step for the Raw Materials Preparation at Chungang Corp

SiO2含量对人造富矿产量质量进而对高炉和转炉生产有很大的影响，精料方针在着钢的核心内容就是降硅。具体办法是控制硅源，严格采购制度，提高烧结燃料用煤固定碳含量。

The SiO2 content in raw materials for iron making has a remarkable influence on thequality and output of the enriched ores, and in turn on the performance of the blast furnace andconverter. The key step for raw materials refining at Chungang Corp. is to lower the SiO2 content in theraw materials; and the specific measures for it include controlling the Si-supplying soume, strictlyenforcing the materials purchase regulations, and enhancing the fixed carben cotent in the sinteringed.
