熱風(fēng)爐是高爐系統(tǒng)中非常重要的設(shè)備之一。如何保證熱風(fēng)爐產(chǎn)生持續(xù)高溫是熱風(fēng)爐控制的目的。因此，如何進(jìn)行燒爐操作和何時(shí)換爐是熱風(fēng)爐控制的關(guān)鍵。本文首次利用CBR 技術(shù)對處于即將送風(fēng)的熱風(fēng)爐進(jìn)行送風(fēng)溫度預(yù)測，結(jié)果表明，該方法準(zhǔn)確有效，實(shí)用性強(qiáng)，對處于燃燒期的熱風(fēng)爐具有很重要的指導(dǎo)意義。
關(guān)鍵詞 基于實(shí)例的推理（CBR）；k-最近鄰算法（KNN）；預(yù)測 熱風(fēng)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.
