保护渣熔融特性,基础渣成分,添加剂种类及数量的关系;低炭保护渣的粘模现象;保护渣的铺展性能;特别是保护渣对钢锭底部表面质量的影响,是国内外保护渣使用过程中存在的问题。针对这些问题,在我院进行了大量的基础性研究,突破了一些传统的概念。在此基础上又进行了最优化配方设计,并在工厂进行了小规模试验。 为了验证研究成果,在齐齐哈尔钢厂进行生产性试验。经过两年浇钢50万吨的实践
The relationship between slag melting characteristics, the basic slag composition, the type and amount of additives; sticking phenomenon of low-carbon mold flux; the spreading performance of mold flux; especially the influence of mold flux on the surface quality of ingot bottom is the use of mold flux at home and abroad In the existing problems. In response to these problems, we carried out a large number of basic research in our hospital and broke through some traditional concepts. Based on this, the optimal formulation design was carried out and a small-scale test was carried out in the factory. In order to verify the research results, a productive test was carried out at Qiqihar Steel Works. After two years of steel pouring 500,000 tons of practice
