style="text-indent:25px">在我國(guó)，每個(gè)企業(yè)的熱處理規(guī)模都不大，就連航空企業(yè)也一樣，大的熱處理專業(yè)廠幾乎就沒(méi)有，熱處理還沒(méi)有實(shí)現(xiàn)專業(yè)化，量上不去，生產(chǎn)成本自然就高起來(lái)，利潤(rùn)也就很低。如此一來(lái)，企業(yè)就會(huì)覺(jué)得真空設(shè)備價(jià)格很高，購(gòu)買(mǎi)真空熱處理設(shè)備的能力、意愿就不是很強(qiáng)烈。我國(guó)很多小企業(yè)根本就沒(méi)有能力購(gòu)買(mǎi)先進(jìn)的熱處理設(shè)備，也就滋生了一批中低端真空設(shè)備制造企業(yè)，他們生產(chǎn)的零部件質(zhì)量也不會(huì)很高，壽命自然得不到保障，這就進(jìn)入了惡性循環(huán)。吊詭的是，這些中低端的，乃至作坊式的廠子依然生存得很好，反過(guò)來(lái)說(shuō)明了我國(guó)制造業(yè)存在的弊端。</p><p style="text-indent:25px">在真空爐的不同位置積垢的位置也不相同，積垢厚的地方，透氣截面積減小，氣流的阻力增大，使積垢少的地方煙氣流速加快，時(shí)間稍長(zhǎng)，會(huì)形成高速氣流通道。因?yàn)闊煔庵袔в性S多不可燃的固體物質(zhì)，是處在高速氣流通道內(nèi)的換熱管很快磨損，被迫停爐檢修。由于被加熱表面的積垢會(huì)越積越厚，形成保溫層，直接影響熱交換，降低鍋爐的熱率。真空爐是需要把熱能轉(zhuǎn)化成動(dòng)能或機(jī)械能的設(shè)備，因此需要大量的換熱表面，由于被加熱表面的吸附作用，燃料中的不可燃物質(zhì)被吸附在換熱表面而且越來(lái)越厚，這些殘余物不僅妨礙了熱量的傳遞，而且導(dǎo)致被加熱表面的腐蝕，燃料中的灰分越大低熔點(diǎn)的物質(zhì)越多，則會(huì)留下大量的灰分。導(dǎo)致被加熱表面出現(xiàn)厚厚的積垢，導(dǎo)致設(shè)備減少使用壽命，對(duì)于企業(yè)來(lái)說(shuō)設(shè)備是保障生產(chǎn)力的要素，所以為了更好的研發(fā)請(qǐng)及時(shí)清理真空爐的衛(wèi)生?，F(xiàn)代先進(jìn)的真空爐加熱室采用較優(yōu)隔熱材料制成的隔熱墻和屏障，可將電熱能量集中于加熱室內(nèi)，節(jié)能效果明顯。</p><div
