style="text-indent:25px">工業(yè)爐的創(chuàng)造和發(fā)展對(duì)人類進(jìn)步起著十分重要的作用。中國在商代出現(xiàn)了較為完善的煉銅爐，爐溫達(dá)到1200℃，爐子內(nèi)徑達(dá)0.8米。在春秋戰(zhàn)國時(shí)期，人們?cè)谌坫~爐的基礎(chǔ)上進(jìn)一步掌握了提高爐溫的技術(shù)，從而生產(chǎn)出了鑄鐵。1794年，世界上出現(xiàn)了熔煉鑄鐵的直筒形沖天爐。后到1864年，法國人馬丁運(yùn)用英國人西門子的蓄熱式爐原理，建造了用氣體燃料加熱的一臺(tái)煉鋼平爐。他利用蓄熱室對(duì)空氣和煤氣進(jìn)行高溫預(yù)熱，從而保證了煉鋼所需的1600℃以上的溫度。1900年前后，電能供應(yīng)逐漸充足，開始使用各種電阻爐、電弧爐和有芯感應(yīng)爐。二十世紀(jì)50年代，無芯感應(yīng)爐得到迅速發(fā)展。后來又出現(xiàn)了電子束爐，利用電子束來沖擊固態(tài)燃料，能強(qiáng)化表面加熱和熔化高熔點(diǎn)的材料。</p><p style="text-indent:25px">提高爐子熱效率的基本措施是：充分提高燃燒效率，強(qiáng)化對(duì)工件的傳熱；盡可能地連續(xù)生產(chǎn)和滿負(fù)荷工作；設(shè)置預(yù)熱器，對(duì)空氣及煤氣進(jìn)行預(yù)熱，以回收煙氣余熱；采用比熱容和熱導(dǎo)率低的耐火材料，以減少爐墻蓄熱和散熱損失。為了使?fàn)t溫恒定和實(shí)現(xiàn)規(guī)定的升溫速度，除必須根據(jù)工藝要求、預(yù)熱器和爐用機(jī)械型式、燃料和燃燒裝置類別、工業(yè)爐排煙方式等確定優(yōu)良的爐型結(jié)構(gòu)外，還需要對(duì)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(jìn)行相互調(diào)節(jié)，以實(shí)現(xiàn)爐溫、爐氣氛或爐壓的自動(dòng)控制。設(shè)備發(fā)展工業(yè)爐行業(yè)采用脈沖燃燒的必要性。較好工業(yè)產(chǎn)品對(duì)爐內(nèi)溫度場的均勻性要求較高，對(duì)燃燒氣氛的穩(wěn)定可控性要求較高，使用傳統(tǒng)的連續(xù)燃燒控制無法實(shí)現(xiàn)。隨著寬斷面、大容量的工業(yè)爐的出現(xiàn)，必須采用脈沖燃燒控制技術(shù)才能控制爐內(nèi)溫度場的均勻性。砌體的作用是使工業(yè)爐在加熱或熔煉過程中承受高溫負(fù)荷，減少熱量損失，抵抗化學(xué)侵蝕并具有一定的結(jié)構(gòu)強(qiáng)度。</p><div
