您對于四川(chuan)工字鋼(gang)的(de)孔型設計了解多少(shao)呢？下面是(shi)小編(bian)收集整(zheng)理的(de)一(yi)些(xie)信息(xi)，供(gong)大家參考(kao)。

工(gong)(gong)(gong)(gong)(gong)字(zi)(zi)鋼(gang)(gang)(gang)的(de)規格是用腰寬(kuan)(kuan)(kuan)的(de)厘米值來(lai)表(biao)示的(de)，如(ru)10號(hao)工(gong)(gong)(gong)(gong)(gong)字(zi)(zi)鋼(gang)(gang)(gang)，其腰寬(kuan)(kuan)(kuan)為(wei)10cm。工(gong)(gong)(gong)(gong)(gong)字(zi)(zi)鋼(gang)(gang)(gang)的(de)種(zhong)類有熱軋(ya)普通工(gong)(gong)(gong)(gong)(gong)字(zi)(zi)鋼(gang)(gang)(gang)、輕型工(gong)(gong)(gong)(gong)(gong)字(zi)(zi)鋼(gang)(gang)(gang)和(he)寬(kuan)(kuan)(kuan)平行腿工(gong)(gong)(gong)(gong)(gong)字(zi)(zi)鋼(gang)(gang)(gang)（H型鋼(gang)(gang)(gang)）。我(wo)國(guo)熱軋(ya)普通工(gong)(gong)(gong)(gong)(gong)字(zi)(zi)鋼(gang)(gang)(gang)的(de)腰寬(kuan)(kuan)(kuan)為(wei)100～630mm，表(biao)示為(wei)No.10～No.63，腿內側壁斜(xie)度為(wei)1：6。軋(ya)制工(gong)(gong)(gong)(gong)(gong)字(zi)(zi)鋼(gang)(gang)(gang)的(de)孔(kong)型系(xi)統有直軋(ya)孔(kong)型系(xi)統、斜(xie)軋(ya)孔(kong)型系(xi)統和(he)混合(he)孔(kong)型系(xi)統。此(ci)外，工(gong)(gong)(gong)(gong)(gong)字(zi)(zi)鋼(gang)(gang)(gang)還可以(yi)采(cai)用特(te)殊軋(ya)法(fa)。

（1）直軋(ya)(ya)孔型系(xi)統。直軋(ya)(ya)孔型系(xi)統是指(zhi)工(gong)字(zi)鋼孔型的兩個開口腿(tui)同(tong)時處于軋(ya)(ya)輥軸(zhou)線(xian)的同(tong)一側，腰與軋(ya)(ya)輥軸(zhou)線(xian)平(ping)行的孔型系(xi)統。

其優(you)點是軋(ya)輥軸向力小(xiao)(xiao)，軸向竄動(dong)小(xiao)(xiao)，不需工作(zuo)斜面，孔型(xing)占用輥身長(chang)度小(xiao)(xiao)，在(zai)輥身長(chang)度一定的條件下(xia)可多配孔型(xing)。

（2）斜軋孔(kong)型系(xi)統。這(zhe)種孔(kong)型系(xi)統是指(zhi)工字(zi)鋼(gang)孔(kong)型的兩個開口腿不同時處于(yu)腰部的同一側，腰與水(shui)平(ping)軸(zhou)線有(you)一夾角(jiao)。

（3）混合孔(kong)(kong)型系統(tong)。根據軋機和(he)產品(pin)的(de)特點，為充分發揮各自系統(tong)的(de)優點，克服缺點，往(wang)往(wang)采用(yong)混合孔(kong)(kong)型系統(tong)，即兩種(zhong)以上(shang)系統(tong)的(de)組合。如(ru)成(cheng)品(pin)孔(kong)(kong)和(he)成(cheng)品(pin)前孔(kong)(kong)采用(yong)直(zhi)腿(tui)斜軋孔(kong)(kong)型系統(tong)，其他孔(kong)(kong)型采用(yong)彎腿(tui)斜軋系統(tong)；或者粗軋孔(kong)(kong)采用(yong)直(zhi)軋系統(tong)，然后3～4個精軋孔(kong)(kong)采用(yong)直(zhi)腿(tui)斜扎孔(kong)(kong)等。

（4）特殊軋(ya)(ya)(ya)法(fa)。由于某種原(yuan)因(yin)采用通常(chang)的(de)軋(ya)(ya)(ya)制(zhi)(zhi)方法(fa)難以軋(ya)(ya)(ya)出要(yao)求的(de)工字鋼時(shi)，可采用特殊軋(ya)(ya)(ya)法(fa)，充分(fen)利用不(bu)均勻變形和(he)孔型(xing)設計的(de)技巧。例如，當鋼坯(pi)斷面較(jiao)(jiao)窄而要(yao)求軋(ya)(ya)(ya)制(zhi)(zhi)較(jiao)(jiao)寬(kuan)的(de)工字鋼時(shi)，可采用波浪式軋(ya)(ya)(ya)法(fa)；又如當坯(pi)料較(jiao)(jiao)寬(kuan)而要(yao)求軋(ya)(ya)(ya)制(zhi)(zhi)較(jiao)(jiao)小號工字鋼時(shi)，可采用負寬(kuan)展(zhan)軋(ya)(ya)(ya)制(zhi)(zhi)等(deng)。

通過以上的介紹，您對于四川工字鋼有了解得更多一點嗎？
