1.熱軋

用連鑄板坯或初軋(ya)(ya)(ya)(ya)(ya)板坯作原料，經步進式加熱(re)爐(lu)加熱(re)，高壓(ya)水除磷后進入粗軋(ya)(ya)(ya)(ya)(ya)機(ji)，粗軋(ya)(ya)(ya)(ya)(ya)料經切(qie)(qie)頭、尾(wei)、再進入精(jing)軋(ya)(ya)(ya)(ya)(ya)機(ji)，實施計算機(ji) 控制(zhi)軋(ya)(ya)(ya)(ya)(ya)制(zhi)，終(zhong)軋(ya)(ya)(ya)(ya)(ya)后即經過層流冷卻（計算機(ji)控制(zhi)冷卻速率）和卷(juan)(juan)取(qu)機(ji)卷(juan)(juan)取(qu)、成為直(zhi)發(fa)卷(juan)(juan)。直(zhi)發(fa)卷(juan)(juan)的頭、尾(wei)往(wang)往(wang)呈舌狀(zhuang)及魚尾(wei)狀(zhuang)，厚度、 寬度精(jing)度較差，邊(bian)部常存在浪形、折邊(bian)、塔形等缺(que)陷。其卷(juan)(juan)重較重、鋼卷(juan)(juan)內(nei)徑為760mm。(一般(ban)制(zhi)管行業(ye)喜(xi)歡使用。)將直(zhi)發(fa)卷(juan)(juan)經切(qie)(qie)頭、 切(qie)(qie)尾(wei)、切(qie)(qie)邊(bian)及多(duo)道次的矯直(zhi)、平整等精(jing)整線處理后，再切(qie)(qie)板或重卷(juan)(juan)，即成為：熱(re)軋(ya)(ya)(ya)(ya)(ya)鋼板、平整熱(re)軋(ya)(ya)(ya)(ya)(ya)鋼卷(juan)(juan)、縱切(qie)(qie)帶(dai)等產品。熱(re)軋(ya)(ya)(ya)(ya)(ya)精(jing)整卷(juan)(juan)若經酸洗(xi)去除氧(yang)化皮并(bing)涂油后即成熱(re)軋(ya)(ya)(ya)(ya)(ya)酸洗(xi)板卷(juan)(juan)。

2. 冷軋

用(yong)(yong)熱軋(ya)鋼卷(juan)(juan)(juan)為原料，經酸(suan)洗去(qu)除氧化(hua)皮后進(jin)(jin)行冷連(lian)(lian)軋(ya)，其成品(pin)為軋(ya)硬(ying)(ying)(ying)卷(juan)(juan)(juan)，由于連(lian)(lian)續冷變形引(yin)起的(de)(de)冷作硬(ying)(ying)(ying)化(hua)使軋(ya)硬(ying)(ying)(ying)卷(juan)(juan)(juan)的(de)(de)強(qiang)度、硬(ying)(ying)(ying)度上升、韌塑(su)指標(biao)下降，沖壓性能惡化(hua)，只能用(yong)(yong)于簡單變形的(de)(de)零件。軋(ya)硬(ying)(ying)(ying)卷(juan)(juan)(juan)可作為熱鍍鋅(xin)廠的(de)(de)原料，因(yin)為熱鍍鋅(xin)機組均(jun)(jun)設置有退火(huo)線。軋(ya)硬(ying)(ying)(ying)卷(juan)(juan)(juan)重一(yi)般(ban)在6~13.5噸，鋼卷(juan)(juan)(juan)內徑(jing)為610mm。一(yi)般(ban)冷連(lian)(lian)軋(ya)板、卷(juan)(juan)(juan)均(jun)(jun)應(ying)(ying)經過連(lian)(lian)續退火(huo)（CAPL機組）或罩(zhao)式(shi)爐進(jin)(jin)行去(qu)退火(huo)處理，消除冷作硬(ying)(ying)(ying)化(hua)及軋(ya)制應(ying)(ying)力，達到標(biao)準規(gui)定的(de)(de)力學(xue)性能指標(biao)。冷軋(ya)鋼板的(de)(de)表面質量、外觀、尺寸精度均(jun)(jun)優于熱軋(ya)板。
