style="text-indent:25px">工業(yè)爐的結(jié)構(gòu)、加熱工藝、溫度控制和爐內(nèi)氣氛等，都會(huì)直接影響加工后的產(chǎn)品質(zhì)量。在鍛造加熱爐內(nèi)，提高金屬的加熱溫度，可以降低變形阻力，但溫度過高會(huì)引起晶粒長大、氧化或過燒，嚴(yán)重影響工件質(zhì)量。在熱處理過程中，如果把鋼加熱到臨界溫度以上的某一點(diǎn)，然后突然冷卻，就能提高鋼的硬度和強(qiáng)度；如果加熱到臨界溫度以下的某一點(diǎn)后緩慢冷卻，則又能使鋼的硬度降低而使韌性提高。為了獲得尺寸精確和表面光潔的工件，或者為了減少金屬氧化以達(dá)到保護(hù)模具、減少加工余量等目的，可以采用各種少無氧化加熱爐。在敞焰的少無氧化加熱爐內(nèi)，利用燃料的不完全燃燒產(chǎn)生還原性氣體，在其中加熱工件可使氧化燒損率降低到0.3%以下。</p><p style="text-indent:25px">工業(yè)爐燃燒過程強(qiáng)化的途徑：強(qiáng)化燃燒過程主要從提高溫度和加強(qiáng)氣流混合等方面來考慮。采用不同的燃燒方式是實(shí)現(xiàn)強(qiáng)化燃燒的初選，對(duì)于需要強(qiáng)化燃燒的場(chǎng)所，應(yīng)盡量采用預(yù)混燃燒方式，一次空氣系數(shù)越大，燃燒強(qiáng)度越大。對(duì)于燃燒方式一定的燃燒設(shè)備，實(shí)用的強(qiáng)化燃燒的主要途徑有以下幾方面（主要用于工業(yè)燃燒設(shè)備）。 (一)預(yù)熱燃?xì)夂涂諝猓梢蕴岣呋鹧鎮(zhèn)鞑ニ俣?，增加反?yīng)區(qū)內(nèi)的反應(yīng)速度，提高燃燒溫度，從而增加燃燒強(qiáng)度。 (二)加強(qiáng)紊動(dòng)，能增加大氣式和擴(kuò)散式燃燒燃燒強(qiáng)度。 (三)煙氣再循環(huán) ，可提高反應(yīng)區(qū)的溫度，從而增加燃燒強(qiáng)度。 (四)應(yīng)用旋轉(zhuǎn)氣流，能改善混合過程。工業(yè)爐選用原則：與前后工序的關(guān)系和銜接。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="遼寧各種工業(yè)爐技術(shù),工業(yè)爐"

style="text-indent:25px">提高工業(yè)爐燃燒的方法:擴(kuò)散式燃燒。在燃燒之前，煤氣不與空氣混合，不形成混合氣，只是把煤氣噴射到空氣中，使其燃燒。全為二次空氣，不混入一次空氣。在層流狀態(tài)下，擴(kuò)散燃燒依靠分子擴(kuò)散作用使周圍氧氣進(jìn)入燃燒區(qū)，在湍流狀態(tài)下，則依靠湍流擴(kuò)散作用來獲得燃燒所需的氧氣。由于分子擴(kuò)散進(jìn)行得比較緩慢，因此層流擴(kuò)散燃燒的速度取決于氧的擴(kuò)散速度。燃燒的化學(xué)反應(yīng)進(jìn)行得比較快，因此火焰焰面厚度比較小。特點(diǎn)：火焰平穩(wěn)，不回火、沒有滅火噪音，不需要調(diào)節(jié)空氣等。燃燒較高溫度達(dá)1200°C。應(yīng)用：煤氣快速熱水器、常明火、點(diǎn)火棒都采用這種方式。遼寧各種工業(yè)爐技術(shù)</p></p><br
