熱風爐是高爐系統(tǒng)中非常重要的設備之一。如何保證熱風爐產生持續(xù)高溫是熱風爐控制的目的。因此，如何進行燒爐操作和何時換爐是熱風爐控制的關鍵。本文首次利用CBR 技術對處于即將送風的熱風爐進行送風溫度預測，結果表明，該方法準確有效，實用性強，對處于燃燒期的熱風爐具有很重要的指導意義。
關鍵詞 基于實例的推理（CBR）；k-最近鄰算法（KNN）；預測 熱風爐
Abstract The hot blast stove is very important to the blast furnace. The objective is how to improve and maintain the flow-rate and temperature of the blast air to ensure efficient furnace operation. The controls of the hot blast stoves mainly conclude on-gas control and auto-changeover. We use the method of CBR to predict the hot blast temperature. The results show, the method is valid and practical, and it has important interest of guidance to the on-gas hot blast stove.
