摘 要: 為了研究轉(zhuǎn)爐爐襯風口區(qū)和爐口區(qū)易于受損的成因， 通過數(shù)值模擬的方法建立了爐襯在吹煉的不同時期的溫度場數(shù)學模型， 并對之進行了分析。 研究結(jié)果表明： 在風口區(qū)和爐口區(qū)， 從內(nèi)壁到外壁的溫度分布極不均勻， 尤其是在剛加入銅锍時風口區(qū)和爐口區(qū)內(nèi)壁的溫度梯度最大； 爐襯溫度的劇烈變化是導致風口區(qū)和爐口區(qū)爐襯容易損壞的重要原因。
關鍵字: 數(shù)值模擬； 溫度場； 轉(zhuǎn)爐爐襯； 溫度梯度

Abstract:The mathematical model of temperature field of blast nozzle and throat of converter lining was established in different operating periods by numericalsimulation. The reason that caused blast nozzle and throat being easily damaged was pointed out and analyzed in detail. The research result shows that the temperature distributions are very different from inside wall to outside wall in blst nozzle and throat, especially, the temperature gradient is the largest at the moment of mattefeeding. This is a major reason that caused blast nozzle and throat being easily damaged.
Key words: numerical simulation； temperature field； lining of converter
