style="text-indent:25px">在我國，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)廠幾乎就沒有，熱處理還沒有實(shí)現(xiàn)專業(yè)化，量上不去，生產(chǎn)成本自然就高起來，利潤也就很低。如此一來，企業(yè)就會(huì)覺得真空設(shè)備價(jià)格很高，購買真空熱處理設(shè)備的能力、意愿就不是很強(qiáng)烈。我國很多小企業(yè)根本就沒有能力購買先進(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，反過來說明了我國制造業(yè)存在的弊端。北京臥式真空爐設(shè)備</p></p><br
