S275JR工字鋼

工(gong)(gong)(gong)(gong)字(zi)(zi)(zi)鋼(gang)(gang)(gang)(gang)(gang)主要分(fen)為普(pu)(pu)通工(gong)(gong)(gong)(gong)字(zi)(zi)(zi)鋼(gang)(gang)(gang)(gang)(gang)、輕(qing)型(xing)(xing)工(gong)(gong)(gong)(gong)字(zi)(zi)(zi)鋼(gang)(gang)(gang)(gang)(gang)和寬(kuan)翼(yi)(yi)緣工(gong)(gong)(gong)(gong)字(zi)(zi)(zi)鋼(gang)(gang)(gang)(gang)(gang)。按(an)翼(yi)(yi)緣與腹板(ban)高度比又(you)(you)分(fen)為寬(kuan)幅、中幅、窄幅寬(kuan)翼(yi)(yi)緣工(gong)(gong)(gong)(gong)字(zi)(zi)(zi)鋼(gang)(gang)(gang)(gang)(gang)。前二者生(sheng)產的規格(ge)為10—60號，即相(xiang)應的高度為10cm—60cm。在(zai)相(xiang)同高度下，輕(qing)型(xing)(xing)工(gong)(gong)(gong)(gong)字(zi)(zi)(zi)鋼(gang)(gang)(gang)(gang)(gang)翼(yi)(yi)緣窄、腹板(ban)薄、重量輕(qing)。寬(kuan)翼(yi)(yi)緣工(gong)(gong)(gong)(gong)字(zi)(zi)(zi)鋼(gang)(gang)(gang)(gang)(gang)又(you)(you)稱(cheng)H型(xing)(xing)鋼(gang)(gang)(gang)(gang)(gang)，斷(duan)面特點是兩腿平行(xing)，且腿內側沒(mei)有斜(xie)度。它屬于(yu)經(jing)(jing)濟斷(duan)面型(xing)(xing)鋼(gang)(gang)(gang)(gang)(gang)，是在(zai)四輥萬能軋機上軋制的，所以又(you)(you)稱(cheng)“萬能工(gong)(gong)(gong)(gong)字(zi)(zi)(zi)鋼(gang)(gang)(gang)(gang)(gang)”。普(pu)(pu)通工(gong)(gong)(gong)(gong)字(zi)(zi)(zi)鋼(gang)(gang)(gang)(gang)(gang)、輕(qing)型(xing)(xing)工(gong)(gong)(gong)(gong)字(zi)(zi)(zi)鋼(gang)(gang)(gang)(gang)(gang)已(yi)經(jing)(jing)形(xing)成(cheng)國家標準(zhun)。

工(gong)字鋼，提(ti)升(sheng)(sheng)板與卡嵌(qian)槽(cao)中(zhong)間相互載(zai)荷(he)，使提(ti)升(sheng)(sheng)板刺(ci)入夾(jia)緊塊內，一起(qi)夾(jia)緊塊是向(xiang)外(wai)凸起(qi)的，不容易(yi)對工(gong)字鋼的構造抗(kang)(kang)壓(ya)(ya)強(qiang)度產生(sheng)毀壞，提(ti)升(sheng)(sheng)板與卡嵌(qian)槽(cao)協作，促使提(ti)升(sheng)(sheng)板固定不動在工(gong)字鋼上，發(fa)展了工(gong)字鋼的抗(kang)(kang)更改力和構造抗(kang)(kang)壓(ya)(ya)強(qiang)度，適用工(gong)字鋼構造抗(kang)(kang)壓(ya)(ya)強(qiang)度較高的情況(kuang)，有關構造抗(kang)(kang)壓(ya)(ya)強(qiang)度規(gui)定較低的情況(kuang)下，可將提(ti)升(sheng)(sheng)板滑出，減少(shao)成本，應用靈巧。

工字鋼孔型設計:
工字鋼的規格是用腰寬的厘米值來表示的，如10號工字鋼，其腰寬為10cm。工字鋼的種類有熱軋普通工字鋼、輕型工字鋼和寬平行腿工字鋼（H型鋼）。我國熱軋普通工字鋼的腰寬為100～630mm，表示為No.10～No.63，腿內側壁斜度為1：6。軋制工字鋼的孔型系統有直軋孔型系統、斜軋孔型系統和混合孔型系統。此外，工字鋼還可以采用特殊軋法。
（1）直軋孔型系統。直軋孔型系統是指工字鋼孔型的兩個開口腿同時處于軋輥軸線的同一側，腰與軋輥軸線平行的孔型系統。
其優點是軋輥軸向力小，軸向竄動小，不需工作斜面，孔型占用輥身長度小，在輥身長度一定的條件下可多配孔型。
（2）斜軋孔型系統。這種孔型系統是指工字鋼孔型的兩個開口腿不同時處于腰部的同一側，腰與水平軸線有一夾角。
（3）混(hun)合(he)孔(kong)型(xing)系(xi)(xi)(xi)統(tong)(tong)。根據軋(ya)機和(he)產品的特(te)點，為充分發揮各自系(xi)(xi)(xi)統(tong)(tong)的優點，克服缺點，往(wang)(wang)往(wang)(wang)采(cai)用(yong)混(hun)合(he)孔(kong)型(xing)系(xi)(xi)(xi)統(tong)(tong)，即兩種以(yi)上系(xi)(xi)(xi)統(tong)(tong)的組合(he)。如成品孔(kong)和(he)成品前孔(kong)采(cai)用(yong)直腿(tui)斜(xie)軋(ya)孔(kong)型(xing)系(xi)(xi)(xi)統(tong)(tong)，其(qi)他(ta)孔(kong)型(xing)采(cai)用(yong)彎腿(tui)斜(xie)軋(ya)系(xi)(xi)(xi)統(tong)(tong)；或(huo)者粗軋(ya)孔(kong)采(cai)用(yong)直軋(ya)系(xi)(xi)(xi)統(tong)(tong)，最后(hou)3～4個精軋(ya)孔(kong)采(cai)用(yong)直腿(tui)斜(xie)扎孔(kong)等。

（4）特殊軋法。由于某種原因采用通常的軋制方法難以軋出要求的工字鋼時，可采用特殊軋法，充分利用不均勻變形和孔型設計的技巧。例如，當鋼坯斷面較窄而要求軋制較寬的工字鋼時，可采用波浪式軋法；又如當坯料較寬而要求軋制較小號工字鋼時，可采用負寬展軋制等。
