　　經過(guo)一年的(de)質(zhi)量(liang)攻關，攀鋼冷(leng)(leng)軋(ya)廠連(lian)退料(liao)(liao)酸洗定尺(chi)(chi)精(jing)度(du)(du)(du)(du)超標率(lv)大(da)(da)幅(fu)下(xia)降。據悉，目前市場用戶對(dui)于(yu)冷(leng)(leng)軋(ya)成品交(jiao)貨寬度(du)(du)(du)(du)精(jing)度(du)(du)(du)(du)要求為0～1mm。冷(leng)(leng)軋(ya)連(lian)退料(liao)(liao)在(zai)(zai)酸洗工(gong)(gong)(gong)(gong)序切(qie)邊(bian)后，如不(bu)能滿(man)足成品寬度(du)(du)(du)(du)精(jing)度(du)(du)(du)(du)要求，需在(zai)(zai)后工(gong)(gong)(gong)(gong)序進(jin)(jin)行(xing)(xing)二次切(qie)邊(bian)，將直接影響(xiang)后工(gong)(gong)(gong)(gong)序生(sheng)產(chan)效(xiao)率(lv)并導致成材率(lv)低。通過(guo)生(sheng)產(chan)調(diao)研，查(cha)找(zhao)出超標比率(lv)較高(gao)的(de)4個方面的(de)原因。針對(dui)原因，該廠對(dui)連(lian)退料(liao)(liao)定尺(chi)(chi)預留量(liang)進(jin)(jin)行(xing)(xing)優化(hua)調(diao)整，解(jie)決軋(ya)機(ji)(ji)和(he)連(lian)退工(gong)(gong)(gong)(gong)序生(sheng)產(chan)過(guo)程(cheng)中拉縮(suo)量(liang)存(cun)在(zai)(zai)較大(da)(da)差(cha)異的(de)問題；更換部分(fen)磨損(sun)嚴重(zhong)的(de)工(gong)(gong)(gong)(gong)作滑道，重(zhong)新校正滑道位(wei)(wei)置，確保(bao)機(ji)(ji)架(jia)(jia)移行(xing)(xing)平(ping)穩，提(ti)高(gao)設(she)備(bei)運行(xing)(xing)精(jing)度(du)(du)(du)(du)；設(she)計制作樣板尺(chi)(chi)，提(ti)高(gao)圓盤(pan)剪定尺(chi)(chi)作業效(xiao)率(lv)和(he)測量(liang)精(jing)度(du)(du)(du)(du)；對(dui)移行(xing)(xing)絲桿存(cun)在(zai)(zai)間隙進(jin)(jin)行(xing)(xing)調(diao)整，減少機(ji)(ji)架(jia)(jia)竄動(dong)量(liang)和(he)機(ji)(ji)架(jia)(jia)位(wei)(wei)置偏差(cha)；對(dui)機(ji)(ji)架(jia)(jia)旋轉定位(wei)(wei)系統進(jin)(jin)行(xing)(xing)修復和(he)調(diao)整，確保(bao)機(ji)(ji)架(jia)(jia)和(he)刀頭位(wei)(wei)置精(jing)度(du)(du)(du)(du)達(da)到設(she)計標準(zhun)。
