生石灰粉质量对宝钢烧结产质量的影响分析

The Influence Analysis of Quicklime Quality on Output and Quality of Sinter in Bao Steel

摘要: 生石灰粉分散大、密度小、具有粘性，是烧结中的常用熔剂。试验研究及实践生产表明，生石灰粉是铁矿烧结中必不可少的添加剂，而高活性生石灰粉能显著提高烧结矿产质量。通过宝山基地两台烧结机的近一年的生产实践表明，在烧结匀矿配矿结构基本保持不变的前提条件下，生石灰粉的质量改善对烧结的产量及烧结矿的重要质量指标都有显著的正面影响。

Abstract: Because of its large dispersion, small density and sticky viscosity, quicklime powder is widely used in sintering production. Experimental research and practice show that quicklime powder is an essential additive in sintering production. And high active quicklime powder can significantly im-prove the output and quality of sinter. In the condition of the structure of ore blending is basically unchanged, the production practice of two sintering machines at Bao Steel in recent year shows that the quality improvement of quicklime powder has a significant positive effect on the output and quality of sinter.
