为了探讨大型高炉的热控制措施,实现炉热水平的长期稳定和低燃料比生产,以太钢5号高炉6年多的生产实践为基础,对影响大型高炉热制度的主要因素进行统计分析,认识到热制度是在一定的原燃料质量下,各项操作制度共同作用时炉热水平的体现。5号高炉通过采取各项措施,实现了稳定生产,生铁w(Si)在0.35%~0.55%,燃料比在505kg/t以下。
In order to investigate the thermal control measures of large blast furnace and achieve long-term stability of furnace heat level and low fuel ratio production, based on the production practice of Taigang No.5 blast furnace for more than six years, the main factors affecting the thermal system of large blast furnace were statistically analyzed. To the thermal system is the quality of the original fuel, the operation of the system together when the performance of furnace heat level. No.5 blast furnace achieved various measures to achieve stable production. The pig iron w (Si) was 0.35% ~ 0.55% and the fuel ratio was less than 505kg / t.
