跟其他冷彎型鋼(gang)(gang)一樣(yang)，冷彎C型鋼(gang)(gang)生產(chan)過程(cheng)中面臨(lin)的(de)問題就是內(nei)應(ying)力(li)(li)的(de)問題，由于材料(liao)存在較(jiao)大的(de)內(nei)應(ying)力(li)(li)，一旦投(tou)入使用(yong)的(de)話就有可能會發生變形，從(cong)而(er)影(ying)響其使用(yong)效(xiao)果。這些應(ying)力(li)(li)從(cong)何而(er)來(lai)呢?

冷(leng)彎C型(xing)鋼的(de)(de)應力(li)(li)沒有(you)辦(ban)法避免(mian)，在冷(leng)彎C型(xing)鋼的(de)(de)開卷(juan)、滾剪、閉卷(juan)等工藝(yi)過程中(zhong)，都會增加(jia)一定(ding)的(de)(de)內(nei)應力(li)(li)，的(de)(de)就(jiu)是通(tong)過機械(xie)強制變形(xing)導致冷(leng)彎C型(xing)鋼具有(you)一定(ding)的(de)(de)應力(li)(li)。除(chu)此之外，冷(leng)彎C型(xing)鋼如果沒有(you)噴(pen)涂(tu)底漆，孝感鋼結構，那么除(chu)銹和(he)鈍化(hua)工藝(yi)也將會使得(de)它的(de)(de)內(nei)應力(li)(li)釋放(fang)出來，造成彎曲和(he)扭變。

在沒有辦法(fa)避免的情況下，就只能通過(guo)合理的操作(zuo)來減少應力的產(chan)生，作(zuo)為生產(chan)廠(chang)家和用戶而言，也要(yao)重點關注這方面的問(wen)題，確保冷彎C型鋼能被廣泛(fan)的運用。

C型鋼(gang)的特(te)點是(shi)什么(me)？

C型鋼(gang)的(de)用(yong)途非(fei)常廣泛(fan)，鋼(gang)結(jie)構工(gong)業(ye)廠房，用(yong)于(yu)鋼(gang)結(jie)構建(jian)筑的(de)檁條、墻梁，也可(ke)自行組合成輕量型屋(wu)架、托架等(deng)建(jian)筑構件。此外，還可(ke)用(yong)于(yu)機械輕工(gong)制造中的(de)柱、梁和臂等(deng)。C型鋼(gang)是經熱卷(juan)板冷彎加工(gong)而成，壁薄(bo)自重輕，截面性(xing)能優良(liang)，強(qiang)度高，與傳統槽鋼(gang)相(xiang)比，同等(deng)強(qiang)度可(ke)節約材料(liao)30%。
