在高炉生产中,为延长出铁主沟的使用寿命,降低炉前的体力劳动强度,保证正点出铁减少铁量损失等目的,多年来曾反复进行了活动主沟、碳化硅捣料、敷设炭砖及碳化硅砖等各种结构和多种材质的试验,但均未取得显著的效果。主沟成了高炉炉前的“老大难”。一、主沟下落并炭捣的新工艺试验的提出实践证明在高炉上采用炭质材料的效果是肯定
In the blast furnace production, in order to prolong the service life of the main outflow iron, reduce the manual labor intensity in front of the furnace, and ensure the punctuality to reduce the iron loss and other purposes, over the years have repeated the activities of the main channel, silicon carbide ramming, laying Carbon brick and silicon carbide brick and other structures and a variety of materials test, but did not achieve significant results. The main channel has become the blast furnace blast “chronic disaster.” First, the main groove drop and carbon pound new technology test put forward Practice has proved that the use of carbonaceous material on the blast furnace is positive
