曲靖會(huì)澤熱軋精密鋼管用連鑄圓管坯板坯或初軋板坯作原料，經(jīng)步進(jìn)式加熱爐加熱，高壓水除鱗后進(jìn)入粗軋機(jī)，粗軋料經(jīng)切頭、曲靖會(huì)澤本地尾、曲靖會(huì)澤本地再進(jìn)入精軋機(jī)，實(shí)施計(jì)算機(jī) 控制軋制，終軋后即經(jīng)過層流冷卻和卷取機(jī)卷取、曲靖會(huì)澤本地成為直發(fā)卷。直發(fā)卷的頭、曲靖會(huì)澤本地尾往往呈舌狀及魚尾狀，厚度、曲靖會(huì)澤本地 寬度精度較差，邊部常存在浪形、曲靖會(huì)澤本地折邊、曲靖會(huì)澤本地塔形等缺陷。其卷重較重、曲靖會(huì)澤本地鋼卷內(nèi)徑為760mm。將直發(fā)卷經(jīng)切頭、曲靖會(huì)澤本地 切尾、曲靖會(huì)澤本地切邊及多道次的矯直、曲靖會(huì)澤本地平整等精整線處理后，再切板或重卷，即成為：熱軋鋼板、曲靖會(huì)澤本地平整熱軋鋼卷、曲靖會(huì)澤本地縱切帶等產(chǎn)品。熱軋精整卷若經(jīng)酸洗去除氧化皮并涂油后即成熱軋酸洗板卷。
