日本神户制钢所发明了一种有效的冷却转炉炉体的新方法。该方法,就是在出钢后,将出钢口倾至水平状态,然后将含少量水分、白云石粉末等耐火材料的混合冷却物,用喷管向炉衬喷射,促使炉内的空气和高温气体一起迅速排出炉外。这样既可使炉内温度得到速冷,又可将因出钢高温引起的火焰 Japan’s Kobe Steel invented a new method of cooling the converter furnace. The method is that, after tapping, the tapping hole is tilted to a horizontal state, and then a mixed cooling material containing a small amount of refractory material such as water and dolomite powder is sprayed on the lining by a nozzle to promote the air in the furnace and the high-temperature gas Expelled quickly out of the furnace together. This will not only make the furnace temperature to get cold, but also because of the high temperature caused by the flame
