首钢新2号高炉通过1/6模型的布料试验和开炉布料测定,掌握了高炉布料面形状、旋转溜槽倾角a的有效工作范围、a角与料流落点的关系及矿、焦批重不同时的节流阀开度等工艺参数;对于a角、料线、批重和布料方法等的作用也加深了认识。开炉半年以来,高炉操作基本顺利。环形布料时,炉顶煤气中CO_2≈18.5,压量指数(V/ΔP)达到2100。通过试验,还认识到正确设计中心喉管直径的主要依据是防止卡料和同节流阀的面积相称,而不是防止偏料;一定条件下,溜槽长度的选取,应以a的工作范围全部生效为目的。
Shougang No. 2 blast furnace through the 1/6 model of the fabric test and open the cloth measured grasps the shape of the blast furnace cloth surface, the effective working range of a rotating chute a, the relationship between the angle and the flow point and the mine, coke batch weight is not Throttle opening at the same time and other process parameters; for a corner, material lines, weight and fabric method also deepen the understanding of the role. Half a year since the blast furnace operation basically smooth. In the case of a ring-shaped fabric, the top gas has a CO 2 of 18.5 and a pressure index (V / ΔP) of 2100. Through experiments, but also to recognize the correct design of the main basis for the diameter of the throat pipe is to prevent the card with the same proportion of the throttle valve area, rather than to prevent bias; under certain conditions, chute length selection should be a working range of all Effective for the purpose.
