The molten iron of stable temperature and composition is obtained und the condition that adopting duplex melting technology and ladle desulphurizing with porous plug process. 采用双联熔炼工艺,多孔塞法炉外脱硫,获得温度和成分稳定的铁液;
In the light of the characteristics, coefficient of thermal conductivity, density and melting point of the coal dust, this paper surveys the principle of producing the partical thermal insulator for molten steel using coal dust and its service effect in the ladle. 从粉煤灰性质、导热系数及密度、熔点等方面,分析探讨了利用粉煤灰加工钢水颗粒保温剂的原理,以及保温剂在宝钢的实际使用效果。
Results showed that its highbasicity, low melting point and adequate transportability can fulfil the requirement of powder injection in ladle refining. 研究结果表明:合成粉剂碱度高、熔点低、输送性能好,完全满足钢包喷粉要求。
