鋼(gang)(gang)(gang)、輕(qing)型(xing)工(gong)字(zi)(zi)鋼(gang)(gang)(gang)和寬翼(yi)緣(yuan)工(gong)字(zi)(zi)鋼(gang)(gang)(gang)。按翼(yi)緣(yuan)與腹板高(gao)度(du) 比又分為(wei)寬幅、中幅、窄(zhai)幅寬翼(yi)緣(yuan)工(gong)字(zi)(zi)鋼(gang)(gang)(gang)。前二者生產(chan)的規(gui)格為(wei)10—60號，即(ji) 相(xiang)應的高(gao)度(du)為(wei)10 cm—60 cm。在(zai)相(xiang)同高(gao)度(du)下，輕(qing)型(xing)工(gong)字(zi)(zi)鋼(gang)(gang)(gang)翼(yi)緣(yuan)窄(zhai)、腹板薄、重 量輕(qing)。寬翼(yi)緣(yuan)工(gong)字(zi)(zi)鋼(gang)(gang)(gang)又稱H型(xing)鋼(gang)(gang)(gang)，斷(duan)面特(te)點是兩腿(tui)平(ping)行，且腿(tui)內側沒有斜度(du)。 它屬于經濟斷(duan)面型(xing)鋼(gang)(gang)(gang)，是在(zai)四輥萬能軋機上軋制的，所以又稱“萬能工(gong)字(zi)(zi)鋼(gang)(gang)(gang)”。普(pu)通工(gong)字(zi)(zi)鋼(gang)(gang)(gang)、輕(qing)型(xing)工(gong)字(zi)(zi)鋼(gang)(gang)(gang)已經形成國(guo)家(jia)標準。

工(gong)(gong)(gong)字(zi)鋼的(de)(de)規格是用(yong)腰(yao)寬的(de)(de)厘米值來(lai)表示的(de)(de)，如10號工(gong)(gong)(gong)字(zi)鋼，其(qi)腰(yao)寬為(wei)(wei)10cm。工(gong)(gong)(gong)字(zi)鋼的(de)(de)種類有(you)熱軋(ya)(ya)(ya)普通工(gong)(gong)(gong)字(zi)鋼、輕型(xing)(xing)工(gong)(gong)(gong)字(zi)鋼和寬平行(xing)腿(tui)工(gong)(gong)(gong)字(zi)鋼（H型(xing)(xing)鋼）。我國熱軋(ya)(ya)(ya)普通工(gong)(gong)(gong)字(zi)鋼的(de)(de)腰(yao)寬為(wei)(wei)100～630mm，表示為(wei)(wei)No.10～No.63，腿(tui)內側壁(bi)斜度為(wei)(wei)1：6。軋(ya)(ya)(ya)制(zhi)工(gong)(gong)(gong)字(zi)鋼的(de)(de)孔型(xing)(xing)系(xi)統(tong)(tong)有(you)直軋(ya)(ya)(ya)孔型(xing)(xing)系(xi)統(tong)(tong)、斜軋(ya)(ya)(ya)孔型(xing)(xing)系(xi)統(tong)(tong)和混合孔型(xing)(xing)系(xi)統(tong)(tong)。此外(wai)，工(gong)(gong)(gong)字(zi)鋼還(huan)可以采用(yong)特(te)殊軋(ya)(ya)(ya)法。

（1）直軋(ya)孔(kong)型系(xi)統(tong)(tong)(tong)。直軋(ya)孔(kong)型系(xi)統(tong)(tong)(tong)是指工字鋼孔(kong)型的兩個開口腿同時處于軋(ya)輥軸(zhou)線(xian)的同一側，腰(yao)與軋(ya)輥軸(zhou)線(xian)平(ping)行的孔(kong)型系(xi)統(tong)(tong)(tong)。

其優點是(shi)軋(ya)輥(gun)軸(zhou)向力小，軸(zhou)向竄(cuan)動小，不(bu)需工(gong)作斜面，孔型占用輥(gun)身長度小，在輥(gun)身長度一定的條件下可多配(pei)孔型。

（2）斜(xie)軋孔型(xing)(xing)系統(tong)。這種孔型(xing)(xing)系統(tong)是指(zhi)工字鋼孔型(xing)(xing)的兩個開口腿不同時處于腰(yao)(yao)部(bu)的同一側，腰(yao)(yao)與水平軸線有一夾(jia)角。

（3）混合孔(kong)型(xing)系統。根據軋(ya)機和產品的特點，為充分(fen)發揮各自系統的優點，克(ke)服缺(que)點，往往采用混合孔(kong)型(xing)系統，即(ji)兩種以上系統的組(zu)合。如(ru)成品孔(kong)和成品前孔(kong)采用直腿(tui)斜軋(ya)孔(kong)型(xing)系

 統(tong)，其他孔(kong)型(xing)采用(yong)(yong)(yong)彎腿斜(xie)軋(ya)(ya)(ya)系(xi)統(tong)；或者粗軋(ya)(ya)(ya)孔(kong)采用(yong)(yong)(yong)直(zhi)軋(ya)(ya)(ya)系(xi)統(tong)，最后3～4個精軋(ya)(ya)(ya)孔(kong)采用(yong)(yong)(yong)直(zhi)腿斜(xie)扎孔(kong)等。（4）特殊軋(ya)(ya)(ya)法(fa)。由于某種(zhong)原因(yin)采用(yong)(yong)(yong)通常的(de)軋(ya)(ya)(ya)制方法(fa)難以軋(ya)(ya)(ya)出要求的(de)工字鋼時，可采用(yong)(yong)(yong)特殊軋(ya)(ya)(ya)法(fa)，充分利(li)用(yong)(yong)(yong)不(bu)均勻變形和(he)孔(kong)型(xing)設計的(de)技巧。例(li)如，當鋼坯(pi)斷面較窄而要求軋(ya)(ya)(ya)制較寬的(de)

 工字鋼時，可采用(yong)波浪式(shi)軋法；又如當坯料(liao)較寬而要求軋制較小號工字鋼時，可采用(yong)負寬展軋制等。

應用(yong)特點編輯工字型鋼不論是(shi)普通型還是(shi)輕(qing)型的(de)，由于截面尺寸均(jun)相對較(jiao)高(gao)、較(jiao)窄，故(gu)(gu)對截面兩個(ge)主軸的(de)慣(guan)性(xing)矩相差較(jiao)大，故(gu)(gu)僅能直接用(yong)于在(zai)其腹板平面內(nei)受彎的(de)構件或將其組(zu)成(cheng)格構式受力構件
