目前卷軋中厚(hou)板軋機的主要有(you)以(yi)下三種(zhong)種(zhong)生產工藝：

 1. 單張鋼板往復(fu)軋制方式

   這種(zhong)方式主要(yao)用于軋制厚(hou)度(du)大于20毫(hao)米的厚(hou)鋼(gang)板(ban)，使用較長(chang)的板(ban)坯，當軋制到目標鋼(gang)板(ban)厚(hou)度(du)時，最終(zhong)長(chang)度(du)大于50米（一般不超過100米），軋件直接從出口卷取爐下面送至轉鼓飛剪(jian)，將之剪(jian)切成倍(bei)尺母板(ban)長(chang)度(du)；通過加(jia)速冷卻(que)后進入熱矯直機(ji)及冷床；最后經精整線剪(jian)切出定尺成品鋼(gang)板(ban)。這種(zhong)方式適(shi)于常規(gui)的中厚(hou)板(ban)生產(chan)工藝。

 2. 卷軋鋼板(ban)方式

   這種(zhong)方(fang)(fang)式(shi)(shi)主要用于(yu)軋(ya)(ya)(ya)(ya)制生(sheng)(sheng)產(chan)厚(hou)度不(bu)(bu)超(chao)過20毫(hao)米(mi)的(de)中厚(hou)鋼板。使(shi)(shi)(shi)用較長板坯，先在(zai)軋(ya)(ya)(ya)(ya)機(ji)上經反復可逆軋(ya)(ya)(ya)(ya)制，當軋(ya)(ya)(ya)(ya)件(jian)厚(hou)度不(bu)(bu)超(chao)過25毫(hao)米(mi)時，長軋(ya)(ya)(ya)(ya)件(jian)進入軋(ya)(ya)(ya)(ya)機(ji)入口或(huo)出口卷(juan)(juan)(juan)(juan)取(qu)(qu)(qu)爐進行(xing)保溫，經往(wang)復軋(ya)(ya)(ya)(ya)制，最終軋(ya)(ya)(ya)(ya)至成品厚(hou)度；然(ran)后從出口卷(juan)(juan)(juan)(juan)取(qu)(qu)(qu)爐下面送往(wang)飛(fei)剪(jian)(jian)剪(jian)(jian)切成長度不(bu)(bu)超(chao)過50米(mi)的(de)母(mu)板，再經熱矯直(zhi)機(ji)矯直(zhi)，冷床冷卻，在(zai)精整線剪(jian)(jian)切成定尺長度鋼板。這種(zhong)生(sheng)(sheng)產(chan)工藝(yi)是卷(juan)(juan)(juan)(juan)軋(ya)(ya)(ya)(ya)中厚(hou)板軋(ya)(ya)(ya)(ya)機(ji)特有的(de)生(sheng)(sheng)產(chan)工藝(yi)。卷(juan)(juan)(juan)(juan)軋(ya)(ya)(ya)(ya)板生(sheng)(sheng)產(chan)方(fang)(fang)式(shi)(shi)既(ji)(ji)不(bu)(bu)同于(yu)普通(tong)中板生(sheng)(sheng)產(chan)方(fang)(fang)式(shi)(shi)，也(ye)不(bu)(bu)同于(yu)熱連(lian)軋(ya)(ya)(ya)(ya)鋼卷(juan)(juan)(juan)(juan)生(sheng)(sheng)產(chan)方(fang)(fang)式(shi)(shi)。由(you)于(yu)其采(cai)用的(de)是當軋(ya)(ya)(ya)(ya)件(jian)軋(ya)(ya)(ya)(ya)至厚(hou)度不(bu)(bu)超(chao)過25毫(hao)米(mi)，長軋(ya)(ya)(ya)(ya)件(jian)進入機(ji)前(qian)或(huo)機(ji)后卷(juan)(juan)(juan)(juan)取(qu)(qu)(qu)爐進行(xing)保溫方(fang)(fang)式(shi)(shi)，因此既(ji)(ji)減少(shao)了軋(ya)(ya)(ya)(ya)件(jian)的(de)溫降，也(ye)可使(shi)(shi)(shi)軋(ya)(ya)(ya)(ya)件(jian)在(zai)卷(juan)(juan)(juan)(juan)取(qu)(qu)(qu)爐與軋(ya)(ya)(ya)(ya)機(ji)之間形成張(zhang)力(li)(li)，進而(er)可減小軋(ya)(ya)(ya)(ya)件(jian)縱向的(de)變形抗力(li)(li)。由(you)于(yu)卷(juan)(juan)(juan)(juan)軋(ya)(ya)(ya)(ya)鋼板具有上述特點，因而(er)可使(shi)(shi)(shi)軋(ya)(ya)(ya)(ya)件(jian)軋(ya)(ya)(ya)(ya)得(de)更薄，并能得(de)到較好的(de)板形。

 3. 鋼卷軋制方式

   這(zhe)種方式用于(yu)軋(ya)(ya)(ya)制商品鋼(gang)卷(juan)(juan)。采(cai)用出、入口卷(juan)(juan)取(qu)爐(lu)，將軋(ya)(ya)(ya)件往復(fu)軋(ya)(ya)(ya)至厚2.5～20.0毫米的帶(dai)鋼(gang)，經層流冷(leng)(leng)(leng)卻(que)后進入地下卷(juan)(juan)取(qu)機卷(juan)(juan)成鋼(gang)卷(juan)(juan)。綜(zong)合了熱(re)連軋(ya)(ya)(ya)機和(he)中厚板軋(ya)(ya)(ya)機的技術(shu)(shu)(shu)特點，形(xing)成了現代卷(juan)(juan)軋(ya)(ya)(ya)中厚板軋(ya)(ya)(ya)機的技術(shu)(shu)(shu)特色。采(cai)用的主要技術(shu)(shu)(shu)有：直接(jie)熱(re)裝(zhuang)技術(shu)(shu)(shu)，最高(gao)可達到75％；爐(lu)卷(juan)(juan)軋(ya)(ya)(ya)制工藝技術(shu)(shu)(shu)；控制軋(ya)(ya)(ya)制及熱(re)機軋(ya)(ya)(ya)制工藝技術(shu)(shu)(shu)（可滿足(zu)生產(chan)管線(xian)鋼(gang)、高(gao)強度(du)(du)造船板、高(gao)強度(du)(du)結構鋼(gang)板的要求）；高(gao)精度(du)(du)、快(kuai)速動態自(zi)(zi)動厚度(du)(du)控制技術(shu)(shu)(shu)（AGC）；板形(xing)控制（目前僅限于(yu)軋(ya)(ya)(ya)輥彎輥）技術(shu)(shu)(shu)；控制冷(leng)(leng)(leng)卻(que)及層流冷(leng)(leng)(leng)卻(que)＋加速冷(leng)(leng)(leng)卻(que)技術(shu)(shu)(shu)；全液壓地下卷(juan)(juan)取(qu)機及自(zi)(zi)動踏步控制技術(shu)(shu)(shu)等。
