目(mu)前(qian)卷軋(ya)中厚板(ban)軋(ya)機的主(zhu)要有以下三種(zhong)種(zhong)生(sheng)產工藝：
1. 單張鋼(gang)板(ban)往復軋制方式
這種方式主要用于(yu)(yu)軋制厚度(du)大(da)于(yu)(yu)20毫米(mi)的厚鋼板(ban)(ban)，使(shi)用較(jiao)長(chang)的板(ban)(ban)坯，當軋制到目標鋼板(ban)(ban)厚度(du)時(shi)，最(zui)終長(chang)度(du)大(da)于(yu)(yu)50米(mi)（一般不超過(guo)100米(mi)），軋件(jian)直(zhi)接從出口卷取爐下面送至轉鼓飛剪(jian)，將之剪(jian)切成倍尺(chi)母板(ban)(ban)長(chang)度(du)；通過(guo)加速冷(leng)卻后(hou)(hou)進(jin)入熱(re)矯(jiao)直(zhi)機及冷(leng)床；最(zui)后(hou)(hou)經精整線剪(jian)切出定(ding)尺(chi)成品鋼板(ban)(ban)。這種方式適于(yu)(yu)常規的中厚板(ban)(ban)生產工藝。
2. 卷軋鋼(gang)板方式
這種(zhong)方(fang)(fang)式(shi)(shi)主要(yao)用于軋(ya)(ya)(ya)(ya)(ya)制生(sheng)產(chan)厚(hou)(hou)度不(bu)超(chao)過20毫(hao)米(mi)的中厚(hou)(hou)鋼板(ban)(ban)。使用較(jiao)長(chang)板(ban)(ban)坯，先在軋(ya)(ya)(ya)(ya)(ya)機(ji)(ji)(ji)(ji)上(shang)經(jing)反復可逆軋(ya)(ya)(ya)(ya)(ya)制，當軋(ya)(ya)(ya)(ya)(ya)件(jian)(jian)厚(hou)(hou)度不(bu)超(chao)過25毫(hao)米(mi)時，長(chang)軋(ya)(ya)(ya)(ya)(ya)件(jian)(jian)進(jin)入軋(ya)(ya)(ya)(ya)(ya)機(ji)(ji)(ji)(ji)入口(kou)(kou)或出(chu)(chu)口(kou)(kou)卷(juan)(juan)取(qu)(qu)爐進(jin)行保(bao)溫，經(jing)往復軋(ya)(ya)(ya)(ya)(ya)制，最(zui)終軋(ya)(ya)(ya)(ya)(ya)至成品厚(hou)(hou)度；然后(hou)(hou)從出(chu)(chu)口(kou)(kou)卷(juan)(juan)取(qu)(qu)爐下面(mian)送往飛剪剪切成長(chang)度不(bu)超(chao)過50米(mi)的母(mu)板(ban)(ban)，再經(jing)熱矯(jiao)直機(ji)(ji)(ji)(ji)矯(jiao)直，冷床冷卻，在精整線(xian)剪切成定(ding)尺長(chang)度鋼板(ban)(ban)。這種(zhong)生(sheng)產(chan)工(gong)藝(yi)是(shi)卷(juan)(juan)軋(ya)(ya)(ya)(ya)(ya)中厚(hou)(hou)板(ban)(ban)軋(ya)(ya)(ya)(ya)(ya)機(ji)(ji)(ji)(ji)特有(you)的生(sheng)產(chan)工(gong)藝(yi)。卷(juan)(juan)軋(ya)(ya)(ya)(ya)(ya)板(ban)(ban)生(sheng)產(chan)方(fang)(fang)式(shi)(shi)既(ji)不(bu)同(tong)于普通中板(ban)(ban)生(sheng)產(chan)方(fang)(fang)式(shi)(shi)，也不(bu)同(tong)于熱連軋(ya)(ya)(ya)(ya)(ya)鋼卷(juan)(juan)生(sheng)產(chan)方(fang)(fang)式(shi)(shi)。由于其采用的是(shi)當軋(ya)(ya)(ya)(ya)(ya)件(jian)(jian)軋(ya)(ya)(ya)(ya)(ya)至厚(hou)(hou)度不(bu)超(chao)過25毫(hao)米(mi)，長(chang)軋(ya)(ya)(ya)(ya)(ya)件(jian)(jian)進(jin)入機(ji)(ji)(ji)(ji)前(qian)或機(ji)(ji)(ji)(ji)后(hou)(hou)卷(juan)(juan)取(qu)(qu)爐進(jin)行保(bao)溫方(fang)(fang)式(shi)(shi)，因此既(ji)減少了軋(ya)(ya)(ya)(ya)(ya)件(jian)(jian)的溫降，也可使軋(ya)(ya)(ya)(ya)(ya)件(jian)(jian)在卷(juan)(juan)取(qu)(qu)爐與軋(ya)(ya)(ya)(ya)(ya)機(ji)(ji)(ji)(ji)之(zhi)間形(xing)成張力(li)(li)，進(jin)而可減小軋(ya)(ya)(ya)(ya)(ya)件(jian)(jian)縱向的變形(xing)抗力(li)(li)。由于卷(juan)(juan)軋(ya)(ya)(ya)(ya)(ya)鋼板(ban)(ban)具(ju)有(you)上(shang)述特點，因而可使軋(ya)(ya)(ya)(ya)(ya)件(jian)(jian)軋(ya)(ya)(ya)(ya)(ya)得(de)更薄，并能得(de)到較(jiao)好的板(ban)(ban)形(xing)。
3. 鋼卷軋制方式
這種方式用(yong)于軋(ya)(ya)制商(shang)品鋼卷(juan)(juan)(juan)。采(cai)用(yong)出、入口(kou)卷(juan)(juan)(juan)取(qu)爐，將軋(ya)(ya)件往復(fu)軋(ya)(ya)至厚(hou)2.5～20.0毫米(mi)的(de)帶鋼，經層流冷卻(que)后進入地(di)下卷(juan)(juan)(juan)取(qu)機卷(juan)(juan)(juan)成鋼卷(juan)(juan)(juan)。綜合了熱連軋(ya)(ya)機和中厚(hou)板軋(ya)(ya)機的(de)技(ji)(ji)術特點，形成了現代(dai)卷(juan)(juan)(juan)軋(ya)(ya)中厚(hou)板軋(ya)(ya)機的(de)技(ji)(ji)術特色。采(cai)用(yong)的(de)主(zhu)要(yao)技(ji)(ji)術有：直接熱裝技(ji)(ji)術，最高(gao)(gao)可達到75％；爐卷(juan)(juan)(juan)軋(ya)(ya)制工藝技(ji)(ji)術；控(kong)(kong)制軋(ya)(ya)制及熱機軋(ya)(ya)制工藝技(ji)(ji)術（可滿足(zu)生(sheng)產管線鋼、高(gao)(gao)強度(du)造船板、高(gao)(gao)強度(du)結(jie)構鋼板的(de)要(yao)求）；高(gao)(gao)精度(du)、快(kuai)速動(dong)態自(zi)動(dong)厚(hou)度(du)控(kong)(kong)制技(ji)(ji)術（AGC）；板形控(kong)(kong)制（目前僅限于軋(ya)(ya)輥(gun)彎(wan)輥(gun)）技(ji)(ji)術；控(kong)(kong)制冷卻(que)及層流冷卻(que)＋加速冷卻(que)技(ji)(ji)術；全液壓地(di)下卷(juan)(juan)(juan)取(qu)機及自(zi)動(dong)踏步控(kong)(kong)制技(ji)(ji)術等。
