導衛裝置(zhi)(zhi)(zhi)的(de)(de)(de)(de)(de)(de)作(zuo)用(yong)(yong)是(shi)正確地(di)(di)(di)將(jiang)(jiang)軋(ya)(ya)(ya)(ya)(ya)件(jian)導入軋(ya)(ya)(ya)(ya)(ya)輥(gun)孔(kong)型(xing)；保(bao)證軋(ya)(ya)(ya)(ya)(ya)件(jian)在孔(kong)型(xing)中(zhong)穩(wen)定地(di)(di)(di)變形，并得到所要(yao)求的(de)(de)(de)(de)(de)(de)幾何(he)形狀(zhuang)和尺寸；又順(shun)利(li)地(di)(di)(di)將(jiang)(jiang)軋(ya)(ya)(ya)(ya)(ya)件(jian)由孔(kong)型(xing)中(zhong)導出，防止纏輥(gun)；控制或強(qiang)制軋(ya)(ya)(ya)(ya)(ya)件(jian)扭轉或彎曲變形，高(gao)(gao)(gao)速棒(bang)材導衛，按一定的(de)(de)(de)(de)(de)(de)方向運(yun)動。軋(ya)(ya)(ya)(ya)(ya)鋼機軋(ya)(ya)(ya)(ya)(ya)制率、產品規格(ge)(ge)(ge)都是(shi)用(yong)(yong)戶認可，高(gao)(gao)(gao)棒(bang)導衛，當然市場上出售(shou)的(de)(de)(de)(de)(de)(de)軋(ya)(ya)(ya)(ya)(ya)機廠家(jia)也(ye)(ye)較多，但價(jia)(jia)格(ge)(ge)(ge)卻是(shi)天壤之(zhi)別，價(jia)(jia)格(ge)(ge)(ge)差異大(da)、不(bu)(bu)統(tong)一。那么，軋(ya)(ya)(ya)(ya)(ya)鋼機價(jia)(jia)格(ge)(ge)(ge)不(bu)(bu)統(tong)一的(de)(de)(de)(de)(de)(de)原因(yin)，其如下： ? ? ? 1、軋(ya)(ya)(ya)(ya)(ya)鋼設備型(xing)號不(bu)(bu)同(tong)(tong)(tong)，價(jia)(jia)格(ge)(ge)(ge)不(bu)(bu)同(tong)(tong)(tong)。一般情況下，型(xing)號越(yue)(yue)大(da)，價(jia)(jia)格(ge)(ge)(ge)也(ye)(ye)會相對(dui)越(yue)(yue)高(gao)(gao)(gao)。目前進入軋(ya)(ya)(ya)(ya)(ya)鋼市場的(de)(de)(de)(de)(de)(de)型(xing)號軋(ya)(ya)(ya)(ya)(ya)機在產量、自動化(hua)程(cheng)度、質(zhi)量等方面都要(yao)高(gao)(gao)(gao)于傳統(tong)軋(ya)(ya)(ya)(ya)(ya)機。因(yin)此(ci)，也(ye)(ye)就出現了軋(ya)(ya)(ya)(ya)(ya)機價(jia)(jia)格(ge)(ge)(ge)不(bu)(bu)統(tong)一的(de)(de)(de)(de)(de)(de)原因(yin)。 ? ? ? 2、軋(ya)(ya)(ya)(ya)(ya)機各部(bu)件(jian)材質(zhi)不(bu)(bu)同(tong)(tong)(tong)，價(jia)(jia)格(ge)(ge)(ge)不(bu)(bu)同(tong)(tong)(tong)。軋(ya)(ya)(ya)(ya)(ya)機各部(bu)件(jian)的(de)(de)(de)(de)(de)(de)材質(zhi)多種多樣。機架采(cai)用(yong)(yong)45#鑄鋼價(jia)(jia)格(ge)(ge)(ge)稍高(gao)(gao)(gao)，如果采(cai)用(yong)(yong)鋼板焊接價(jia)(jia)格(ge)(ge)(ge)稍低。軋(ya)(ya)(ya)(ya)(ya)機加工的(de)(de)(de)(de)(de)(de)每(mei)個工序(xu)應(ying)用(yong)(yong)的(de)(de)(de)(de)(de)(de)技術(shu)、方式(shi)不(bu)(bu)同(tong)(tong)(tong)，其價(jia)(jia)格(ge)(ge)(ge)也(ye)(ye)不(bu)(bu)相同(tong)(tong)(tong)。 ? ? ?3、材質(zhi)、配(pei)置(zhi)(zhi)(zhi)不(bu)(bu)同(tong)(tong)(tong)，價(jia)(jia)格(ge)(ge)(ge)不(bu)(bu)同(tong)(tong)(tong)。材質(zhi)的(de)(de)(de)(de)(de)(de)成本(ben)是(shi)影響(xiang)軋(ya)(ya)(ya)(ya)(ya)機不(bu)(bu)統(tong)一的(de)(de)(de)(de)(de)(de)重要(yao)原因(yin)之(zhi)一。另(ling)外，設備配(pei)置(zhi)(zhi)(zhi)高(gao)(gao)(gao)低也(ye)(ye)是(shi)一樣，如果一套軋(ya)(ya)(ya)(ya)(ya)鋼設備應(ying)用(yong)(yong)了很多自動化(hua)配(pei)置(zhi)(zhi)(zhi)，同(tong)(tong)(tong)時(shi)，在線發揮較大(da)作(zuo)用(yong)(yong)，在價(jia)(jia)格(ge)(ge)(ge)方面定要(yao)高(gao)(gao)(gao)出很多。

切(qie)分架(jia)次(ci)(ci)軋(ya)(ya)(ya)(ya)件(jian)(jian)形(xing)狀(zhuang)應(ying)該(gai)具有較(jiao)好的對(dui)稱性， 但是在實際生產(chan)過程中， 以(yi)下(xia)因素可能(neng)導(dao)致切(qie)分架(jia)次(ci)(ci)軋(ya)(ya)(ya)(ya)件(jian)(jian)形(xing)狀(zhuang)偏離(li)標準而(er)造成堆(dui)鋼(gang) ?( 1)入口導(dao)衛(wei)(wei)偏， 軋(ya)(ya)(ya)(ya)件(jian)(jian)一(yi)側(ce)充(chong)滿過度， 另(ling)一(yi)側(ce)欠充(chong)滿， 軋(ya)(ya)(ya)(ya)件(jian)(jian)從切(qie)分架(jia)次(ci)(ci)軋(ya)(ya)(ya)(ya)出后形(xing)成鐮刀彎(wan)造成堆(dui)鋼(gang)。 ?( 2)由(you)于(yu)導(dao)衛(wei)(wei)輪間隙調整、速度調整或鋼(gang)坯溫度的原因造成軋(ya)(ya)(ya)(ya)件(jian)(jian)和導(dao)衛(wei)(wei)輪間隙不匹配(pei)， 軋(ya)(ya)(ya)(ya)件(jian)(jian)在導(dao)衛(wei)(wei)內夾持不穩， 使軋(ya)(ya)(ya)(ya)件(jian)(jian)一(yi)側(ce)充(chong)滿過度，導(dao)衛(wei)(wei)承包， 另(ling)一(yi)側(ce)欠充(chong)滿， 軋(ya)(ya)(ya)(ya)件(jian)(jian)從切(qie)分架(jia)次(ci)(ci)軋(ya)(ya)(ya)(ya)出后頭部由(you)于(yu)不均(jun)勻(yun)變形(xing)而(er)形(xing)成鐮刀彎(wan)造成堆(dui)鋼(gang)。

切分(fen)軋(ya)(ya)制(zhi)工(gong)藝雖然有效的提(ti)高了(le)作(zuo)業率，使產量(liang)大(da)幅度(du)提(ti)高，但(dan)是(shi)受(shou)鋼溫波動(dong)、軋(ya)(ya)槽磨損、孔型(xing)系統(tong)設計、導衛(wei)安(an)裝、軋(ya)(ya)槽加工(gong)精(jing)度(du)等(deng)方面因素影響，使每根軋(ya)(ya)件尺寸都不(bu)可能完全一致，從而形(xing)成線(xian)差(cha)(cha)，線(xian)差(cha)(cha)大(da)時很(hen)容(rong)易影響產品質量(liang)，造成波浪彎、冷床(chuang)亂鋼、3#飛剪堆鋼等(deng)事故的發(fa)生。若想獲得較大(da)的經濟效益(yi)，保(bao)證產品質量(liang)，就必須解決好線(xian)差(cha)(cha)問題。
