对西昌钢钒2号高炉全捣固焦快速开炉实践进行了总结。与顶装焦相比,捣固焦显气孔率低约7%,堆比重增大约8%,燃烧失重率低约3%~5%,为此,全捣固焦开炉装料参数在顶装焦开炉装料参数的基础上进行了修正。通过对捣固焦的冶炼特征、下料轨迹、装料方案、开炉操作制度等方面的优化研究,2号高炉开炉第4天,利用系数达到了2.1以上,实现了高钛型钒钛磁铁矿高炉用全捣固焦的快速开炉。
The practice of rapid opening of full tamping coke in Xichang Steel and Vanadium No.2 blast furnace was summarized. Compared with the top-mounted coke, tamping coke apparent porosity was about 7% lower, the proportion of heap increased by about 8%, the weight loss rate of combustion of about 3% to 5%, therefore, full tamping coke oven loading parameters at the top Coke open furnace charge parameters based on the amendment. Based on the optimization research on the smelting characteristics of tamping coke, feeding trajectory, charging scheme and open furnace operation, the utilization of No.2 blast furnace started the 4th day, and the utilization coefficient reached above 2.1. The high titanium vanadium and titanium Magnetite blast furnace with full tamping coke fast open furnace.
