自1988年二季度以来,湘钢2号高炉采用了自己制作的渣口冷却流槽,这种流槽用φ33mm的铁管并列焊接成弧形,管内通入0.3MPa的冷却水。二年多的实践证明,将这种流槽装在渣口耐火砖上面取代原来的泥套,方便适用,炉况正常时不会烧坏,使用
Since the second quarter of 1988, the No. 2 blast furnace of Xiangtan Iron and Steel Company has adopted its own slag mouth cooling runner, which is welded arc-shaped with φ33mm iron pipe in parallel, and 0.3MPa cooling water is introduced into the pipe. More than two years of practice has proved that the flow channel installed in the slag mouth refractory bricks to replace the original mud cover, easy to apply, the furnace will not burn out when normal, the use of
