厚壁卷管生產過程中，一是(shi)采用回火后(hou)快速冷卻的方法(fa)避免(mian)高(gao)溫(wen)脆性(xing)，獲取韌性(xing)。二是(shi)亞溫(wen)淬火法(fa)通過鋼(gang)種的不完全奧氏體化以有效地(di)改善(shan)有害元素及(ji)雜質，提(ti)(ti)高(gao)韌性(xing)。鋼(gang)板(ban)(ban)鋼(gang)板(ban)(ban)卷筒采用一次成型工藝。軋制時，首先彎曲鋼(gang)板(ban)(ban)的兩端(duan)，直(zhi)徑應小于鋼(gang)板(ban)(ban)卷筒直(zhi)徑。然后(hou)調整床壓，滾動兩到(dao)三次鋼(gang)管。由于亞溫(wen)淬火在α+γ兩相(xiang)區加熱，在保(bao)留部(bu)分(fen)未溶解鐵(tie)素體狀(zhuang)態下進行淬火，在保(bao)持較高(gao)強度(du)的同時，韌性(xing)得(de)到(dao)提(ti)(ti)高(gao)。

 鋼管(guan)卷(juan)筒具有重量輕、切削量少、強度(du)高、加工(gong)(gong)工(gong)(gong)程環保節(jie)能等(deng)優勢(shi)。已(yi)成為發達國家的(de)主流(liu)工(gong)(gong)藝。采用大(da)直徑鋼管(guan)卷(juan)筒，增大(da)了卷(juan)筒與鋼絲繩的(de)直徑比，延長鋼絲繩的(de)使用壽命。由(you)于(yu)亞溫淬火在α+γ兩相區(qu)加熱，在保留部分(fen)未溶(rong)解(jie)鐵素體狀態下進行淬火，在保持較高強度(du)的(de)同時，韌性得到提高。大(da)口徑厚壁卷(juan)管(guan)比無縫鋼管(guan)成本低，可加工(gong)(gong)尺寸以(yi)及厚度(du)范(fan)圍(wei)比較廣泛，采用的(de)坯料(liao)主要以(yi)鋼板為主。大(da)口徑厚壁卷(juan)管(guan)在酸性環境中耐(nai)蝕能力較強。
