目前卷軋中厚(hou)板軋機的主要有以下三種種生產工藝：

 1. 單(dan)張鋼板往復軋制方式(shi)

   這種(zhong)方式(shi)主要用于(yu)軋(ya)制厚(hou)(hou)度大于(yu)20毫(hao)米的厚(hou)(hou)鋼(gang)板(ban)，使用較長(chang)的板(ban)坯，當軋(ya)制到目標鋼(gang)板(ban)厚(hou)(hou)度時，最終長(chang)度大于(yu)50米（一般不(bu)超過100米），軋(ya)件直接從出口(kou)卷取爐下面送至(zhi)轉鼓飛剪，將之剪切成(cheng)倍尺母板(ban)長(chang)度；通過加速冷卻后進入熱矯直機及冷床；最后經精整(zheng)線剪切出定(ding)尺成(cheng)品(pin)鋼(gang)板(ban)。這種(zhong)方式(shi)適(shi)于(yu)常規的中厚(hou)(hou)板(ban)生產工藝。

 2. 卷軋鋼板方式

   這(zhe)種(zhong)方式(shi)(shi)主要用于軋(ya)(ya)(ya)(ya)制生(sheng)產(chan)厚度(du)不(bu)(bu)超過(guo)20毫(hao)(hao)米的(de)(de)中(zhong)厚鋼(gang)(gang)板(ban)。使用較長(chang)(chang)板(ban)坯，先在(zai)軋(ya)(ya)(ya)(ya)機(ji)(ji)上(shang)(shang)經反復可(ke)(ke)逆軋(ya)(ya)(ya)(ya)制，當軋(ya)(ya)(ya)(ya)件(jian)(jian)厚度(du)不(bu)(bu)超過(guo)25毫(hao)(hao)米時，長(chang)(chang)軋(ya)(ya)(ya)(ya)件(jian)(jian)進入軋(ya)(ya)(ya)(ya)機(ji)(ji)入口或出口卷(juan)(juan)取(qu)爐(lu)(lu)進行保(bao)(bao)溫，經往復軋(ya)(ya)(ya)(ya)制，最終(zhong)軋(ya)(ya)(ya)(ya)至成品厚度(du)；然后(hou)從(cong)出口卷(juan)(juan)取(qu)爐(lu)(lu)下面送往飛(fei)剪(jian)剪(jian)切成長(chang)(chang)度(du)不(bu)(bu)超過(guo)50米的(de)(de)母板(ban)，再經熱矯(jiao)直(zhi)機(ji)(ji)矯(jiao)直(zhi)，冷床冷卻，在(zai)精整(zheng)線剪(jian)切成定尺(chi)長(chang)(chang)度(du)鋼(gang)(gang)板(ban)。這(zhe)種(zhong)生(sheng)產(chan)工(gong)藝是(shi)卷(juan)(juan)軋(ya)(ya)(ya)(ya)中(zhong)厚板(ban)軋(ya)(ya)(ya)(ya)機(ji)(ji)特有的(de)(de)生(sheng)產(chan)工(gong)藝。卷(juan)(juan)軋(ya)(ya)(ya)(ya)板(ban)生(sheng)產(chan)方式(shi)(shi)既(ji)不(bu)(bu)同(tong)(tong)于普(pu)通(tong)中(zhong)板(ban)生(sheng)產(chan)方式(shi)(shi)，也不(bu)(bu)同(tong)(tong)于熱連(lian)軋(ya)(ya)(ya)(ya)鋼(gang)(gang)卷(juan)(juan)生(sheng)產(chan)方式(shi)(shi)。由(you)于其采用的(de)(de)是(shi)當軋(ya)(ya)(ya)(ya)件(jian)(jian)軋(ya)(ya)(ya)(ya)至厚度(du)不(bu)(bu)超過(guo)25毫(hao)(hao)米，長(chang)(chang)軋(ya)(ya)(ya)(ya)件(jian)(jian)進入機(ji)(ji)前或機(ji)(ji)后(hou)卷(juan)(juan)取(qu)爐(lu)(lu)進行保(bao)(bao)溫方式(shi)(shi)，因此既(ji)減(jian)少了軋(ya)(ya)(ya)(ya)件(jian)(jian)的(de)(de)溫降，也可(ke)(ke)使軋(ya)(ya)(ya)(ya)件(jian)(jian)在(zai)卷(juan)(juan)取(qu)爐(lu)(lu)與軋(ya)(ya)(ya)(ya)機(ji)(ji)之間形成張(zhang)力(li)，進而可(ke)(ke)減(jian)小軋(ya)(ya)(ya)(ya)件(jian)(jian)縱向的(de)(de)變(bian)形抗力(li)。由(you)于卷(juan)(juan)軋(ya)(ya)(ya)(ya)鋼(gang)(gang)板(ban)具有上(shang)(shang)述特點(dian)，因而可(ke)(ke)使軋(ya)(ya)(ya)(ya)件(jian)(jian)軋(ya)(ya)(ya)(ya)得更薄(bo)，并能(neng)得到(dao)較好(hao)的(de)(de)板(ban)形。

 3. 鋼卷軋制方式

   這種(zhong)方式用(yong)于軋(ya)制(zhi)(zhi)商品鋼卷(juan)。采(cai)用(yong)出、入口卷(juan)取爐，將軋(ya)件往復軋(ya)至厚2.5～20.0毫米的(de)帶鋼，經層流冷(leng)(leng)卻(que)(que)后進入地(di)下卷(juan)取機(ji)卷(juan)成鋼卷(juan)。綜合了(le)熱(re)連軋(ya)機(ji)和中(zhong)厚板軋(ya)機(ji)的(de)技(ji)(ji)術(shu)特點(dian)，形(xing)成了(le)現代卷(juan)軋(ya)中(zhong)厚板軋(ya)機(ji)的(de)技(ji)(ji)術(shu)特色。采(cai)用(yong)的(de)主(zhu)要技(ji)(ji)術(shu)有：直接(jie)熱(re)裝技(ji)(ji)術(shu)，最高可達到75％；爐卷(juan)軋(ya)制(zhi)(zhi)工藝(yi)技(ji)(ji)術(shu)；控制(zhi)(zhi)軋(ya)制(zhi)(zhi)及(ji)熱(re)機(ji)軋(ya)制(zhi)(zhi)工藝(yi)技(ji)(ji)術(shu)（可滿足生產管(guan)線鋼、高強(qiang)度造船(chuan)板、高強(qiang)度結構(gou)鋼板的(de)要求(qiu)）；高精度、快速(su)動(dong)態(tai)自動(dong)厚度控制(zhi)(zhi)技(ji)(ji)術(shu)（AGC）；板形(xing)控制(zhi)(zhi)（目前(qian)僅限于軋(ya)輥彎輥）技(ji)(ji)術(shu)；控制(zhi)(zhi)冷(leng)(leng)卻(que)(que)及(ji)層流冷(leng)(leng)卻(que)(que)＋加速(su)冷(leng)(leng)卻(que)(que)技(ji)(ji)術(shu)；全液(ye)壓地(di)下卷(juan)取機(ji)及(ji)自動(dong)踏步控制(zhi)(zhi)技(ji)(ji)術(shu)等。
