style="text-indent:25px">H型鋼歸于高效經(jīng)濟裁面型材（其它還有冷彎薄壁型鋼、壓型鋼板等），因為截面形狀合理，它們能使鋼材更高地發(fā)揮效能，進步承裁才能。不同于一般工字型的是h型鋼的翼緣進行了加寬，且內(nèi)、外外表通常是平行的，這樣可便于用強度較高度螺栓和其他構(gòu)件銜接。其尺度構(gòu)成合理系列，類型完全，便于規(guī)劃選用。H型鋼的翼緣都是等厚度的，有軋制截面，也有由3塊板焊接組成的組合截面。工字鋼都是軋制截面，因為生產(chǎn)工藝差，翼緣內(nèi)邊有1:10斜度。H型鋼的軋制不同于一般工字鋼但用一套水平軋輥，因為其翼緣較寬且無斜度（或斜度很?。?。故須增設(shè)一組立式軋輥一起進行輥軋，因而，其軋制工藝和設(shè)備都比一般軋機雜亂。國內(nèi)可生產(chǎn)的比較大軋制h型鋼高度為800mm,超過了只能是焊接組合截面。上海角鋼哪個廠好</p><p
