style="text-indent:25px">金屬或物料加熱時吸收的熱量與供入爐內(nèi)的熱量之比，稱為爐子熱效率。連續(xù)式爐比間斷式爐的熱效率高，因為連續(xù)式爐的生產(chǎn)率高，而且是不間斷工作的，爐子熱制度處于穩(wěn)定狀態(tài)，沒有周期性的爐墻蓄熱損失，還由于爐膛內(nèi)部有一個預熱爐料的區(qū)段，煙氣部分余熱為由于爐膛內(nèi)部有一個預熱爐料的區(qū)段，煙氣部分余熱為入爐的冷工件所吸收，降低了離爐煙氣的溫度。為了使爐溫恒定和實現(xiàn)規(guī)定的升溫速度，除必須根據(jù)工藝要求、預熱器和爐用機械型式、燃料和燃燒裝置類別、連續(xù)爐排煙方式等確定優(yōu)良的爐型結構外，還需要對燃料和助燃空氣的流量和壓力，或?qū)﹄姽β实瓤煽刈兞客ㄟ^各種控制單元進行相互調(diào)節(jié)，以實現(xiàn)爐溫、爐氣氛或爐壓的自動控制。</p><p style="text-indent:25px">燒結爐是一種在高溫下，使材料生坯固體顆粒的相互鍵聯(lián)，晶粒長大，空隙(氣孔)和晶界漸趨減少，通過物質(zhì)的傳遞，其總體積收縮，密度增加，結尾成為具有某種顯微結構的致密多晶燒結體的爐具。在粉末冶金、鋰電池制造等行業(yè)具有普遍的應用。燒結過程大體上都要經(jīng)歷升溫、保溫和降溫過程，所以在連續(xù)式燒結爐結構中一般性要設置傳輸裝置依次通過升溫段、保溫段和降溫段。然而以往爐體一般只采用一條段傳送裝置，這樣產(chǎn)品通過升溫段、保溫段和降溫段的速度是一樣的。為了燒結的效果主要看升溫段和保溫段的溫度控制，往往產(chǎn)品的輸送速度比較慢。但是降溫段需要讓產(chǎn)品溫度從高溫降到低溫，在溫降確定的情況下，輸送速度太慢就會要求降溫段設置比較長的距離，增加了爐體投入；同時降溫多是要通過冷卻機構來完成，爐體的加長也導致了冷卻機構的覆蓋區(qū)域比較大，這樣又會增加零件的投入。連續(xù)爐根據(jù)工件的工藝要求調(diào)整網(wǎng)帶運行速度參數(shù)。</p><div

style="text-indent:25px">連續(xù)爐的燃料消耗量、原材料的消耗總量、能源消耗量和產(chǎn)品質(zhì)量都影響著連續(xù)爐的質(zhì)量。燃燒系統(tǒng)自動控制技術是連續(xù)爐運行的中心技術。但由于比較多原因，我國的連續(xù)爐大多存在投入高、能耗高的劣勢。在人工控制方面和燃燒自動化控制技術與工業(yè)發(fā)達國家相比還是存在比較大的差距。在比較長一段時間內(nèi)，國內(nèi)的連續(xù)爐新技術依然處于開發(fā)研究階段，比較多企業(yè)并不重視燃燒系統(tǒng)的研究，從而也就忽視了連續(xù)爐燃燒系統(tǒng)改造的關鍵技術。比較多企業(yè)只是根據(jù)燃燒能力的需要來設計并生產(chǎn)連續(xù)爐，忽視了連續(xù)爐的研究和開發(fā)。連續(xù)爐的生產(chǎn)、運行和控制將浪費大量的人力物力。所以現(xiàn)階段我國的連續(xù)爐燃燒系統(tǒng)還有許多問題，不只在爐的性能方面有待提高，有的還存在一定的安全生產(chǎn)隱患。連續(xù)爐生產(chǎn)連續(xù)進行，生產(chǎn)效率高，產(chǎn)品質(zhì)量穩(wěn)定，節(jié)約能源。湖北連續(xù)爐專業(yè)</p><p

style="text-indent:25px">煉鋼過程一般需要高爐冶煉、鐵水預處理、轉(zhuǎn)爐煉鋼等工序，高爐冶煉后需要利用魚雷罐車、天車等運輸工具將鐵水轉(zhuǎn)運至轉(zhuǎn)爐，在轉(zhuǎn)運過程中，還需要在特定的位置進行脫硫、脫磷和扒渣等操作。這種分散的預處理工序和轉(zhuǎn)運過程具有如下弊端：(1)多次轉(zhuǎn)運過程使得被轉(zhuǎn)運的鐵水熱量被白白耗散，能耗大；(2)轉(zhuǎn)運過程需要配備專門的運輸工具、動力及人力，生產(chǎn)效率低，增加了生產(chǎn)成本；(3)轉(zhuǎn)運和預處理過程會造成氣體和粉塵污染，不利于環(huán)境保護和人體健康。(4)轉(zhuǎn)運過程無法徹底杜絕安全事故的發(fā)生。另外，轉(zhuǎn)爐搖爐出渣、出鐵、進料、加輔料時，因爐口搖離了主煙道，活動爐門提起，內(nèi)層主煙道無法捕集到煙氣，此時煙氣會發(fā)生無組織排放，即便在車間外層裝有環(huán)保煙罩，但通常捕集效果不佳，會使部分煙氣外溢，造成一定程度的低空污染。湖北連續(xù)爐專業(yè)</p></p><br
