一、国外冲天炉送氧方式简况在大约半个世纪以来,用氧气改善冲天炉操作的效果已为实践所证实。但普遍采用把氧简单地送入风管,通过风咀送入冲天炉。国内外一致认为此法对提高铁水温度的作用不大。1962年以来,英国铸铁研究协会的Leyshoon和Selby等人对冲天炉送氧方法进行了广泛研究。证明风口喷氧和炉缸喷氧提高铁水温度的效果比一般富氧送风好的多。如按4%富氧的条件下,不同的送氧方法提高出铁温度的情况大不一样。 First, the foreign cupola oxygen method profile In about half a century, with oxygen to improve the effect of cupola operation has been confirmed by practice. However, the general use of oxygen simply into the duct, into the cupola through the wind Tsui. Both at home and abroad agree that this law has little effect on raising the temperature of hot metal. Since 1962, Leyshoon and Selby of the British Iron Casting Research Association have conducted extensive research on the method of oxygen delivery to the cupola. Proved that tuyere spray oxygen and hearth spray oxygen to improve the effect of hot metal temperature than the average oxygen-rich air supply much better. Such as the 4% oxygen-rich conditions, different oxygen delivery methods to improve the tapping temperature of the situation is quite different.
