苏联目前推广冲天炉前炉铁水的喷氧吹炼法,其特点是:由射向液池的固定氧气雾化铁水流,使氧气与铁水相互作用的相间表面扩展到最大限度,瞬时氧化了0.5%以下的铁水;化学反应放出的热量传递给铁水使铁水过热,避免了高温反应的液相产物对炉衬的冲刷。铁水过热程度,可用单位耗氧量来调节,1吨铁水过热30～120℃,耗氧1～3m~3。在剩余压力作用下高温反应的气相产物,从前炉经过渡槽到冲天炉炉缸,这里的弥散状氧化铁正被底
The Soviet Union currently promoting the cupola furnace oxygen injection blowing method, which is characterized by: a fixed oxygen atomized molten iron flow to the pool, the oxygen and the interaction of molten iron to the maximum phase of the surface, the instantaneous oxidation of 0.5 % Of the molten iron; chemical heat released to the hot metal transfer to hot metal overheating, to avoid the high temperature reaction of liquid products on the lining of the erosion. Hot metal overheating, oxygen consumption can be used to adjust the unit, 1 ton of hot metal overheating 30 ~ 120 ℃, oxygen consumption 1 ~ 3m ~ 3. In the residual pressure of high-temperature gas phase reaction products, from the furnace through the aqueduct to the cupola hearth, where the dispersion of iron oxide is being the end
