目前卷軋(ya)中(zhong)厚板軋(ya)機的主要有以(yi)下三種種生產(chan)工藝(yi)：
1. 單張(zhang)鋼(gang)板往(wang)復軋制(zhi)方式
這種方(fang)式主要(yao)用于軋制厚(hou)度大于20毫米(mi)的(de)厚(hou)鋼板(ban)(ban)，使用較(jiao)長的(de)板(ban)(ban)坯，當軋制到目標鋼板(ban)(ban)厚(hou)度時，最終長度大于50米(mi)（一般不超過(guo)100米(mi)），軋件直接(jie)從出口卷取爐下面送至轉(zhuan)鼓飛剪，將之剪切成倍尺母板(ban)(ban)長度；通過(guo)加(jia)速冷卻后進入熱矯直機及冷床；最后經精整線(xian)剪切出定尺成品鋼板(ban)(ban)。這種方(fang)式適于常規(gui)的(de)中(zhong)厚(hou)板(ban)(ban)生產(chan)工(gong)藝。
2. 卷軋鋼板方(fang)式
這(zhe)種方式(shi)主要用于軋(ya)(ya)(ya)(ya)制(zhi)生產(chan)(chan)(chan)(chan)厚度不(bu)超過(guo)20毫米(mi)(mi)(mi)的(de)(de)中(zhong)(zhong)厚鋼(gang)板(ban)。使用較長(chang)(chang)板(ban)坯(pi)，先在(zai)軋(ya)(ya)(ya)(ya)機(ji)(ji)(ji)上(shang)經反(fan)復可(ke)逆(ni)軋(ya)(ya)(ya)(ya)制(zhi)，當(dang)軋(ya)(ya)(ya)(ya)件(jian)厚度不(bu)超過(guo)25毫米(mi)(mi)(mi)時，長(chang)(chang)軋(ya)(ya)(ya)(ya)件(jian)進(jin)入(ru)(ru)(ru)軋(ya)(ya)(ya)(ya)機(ji)(ji)(ji)入(ru)(ru)(ru)口或(huo)出口卷取(qu)爐進(jin)行保溫，經往復軋(ya)(ya)(ya)(ya)制(zhi)，最終(zhong)軋(ya)(ya)(ya)(ya)至成(cheng)(cheng)品(pin)厚度；然后從(cong)出口卷取(qu)爐下面(mian)送往飛剪剪切成(cheng)(cheng)長(chang)(chang)度不(bu)超過(guo)50米(mi)(mi)(mi)的(de)(de)母板(ban)，再(zai)經熱矯直(zhi)機(ji)(ji)(ji)矯直(zhi)，冷(leng)(leng)床冷(leng)(leng)卻，在(zai)精整線(xian)剪切成(cheng)(cheng)定尺長(chang)(chang)度鋼(gang)板(ban)。這(zhe)種生產(chan)(chan)(chan)(chan)工藝(yi)是卷軋(ya)(ya)(ya)(ya)中(zhong)(zhong)厚板(ban)軋(ya)(ya)(ya)(ya)機(ji)(ji)(ji)特有(you)的(de)(de)生產(chan)(chan)(chan)(chan)工藝(yi)。卷軋(ya)(ya)(ya)(ya)板(ban)生產(chan)(chan)(chan)(chan)方式(shi)既不(bu)同(tong)(tong)于普通中(zhong)(zhong)板(ban)生產(chan)(chan)(chan)(chan)方式(shi)，也(ye)(ye)不(bu)同(tong)(tong)于熱連軋(ya)(ya)(ya)(ya)鋼(gang)卷生產(chan)(chan)(chan)(chan)方式(shi)。由于其采用的(de)(de)是當(dang)軋(ya)(ya)(ya)(ya)件(jian)軋(ya)(ya)(ya)(ya)至厚度不(bu)超過(guo)25毫米(mi)(mi)(mi)，長(chang)(chang)軋(ya)(ya)(ya)(ya)件(jian)進(jin)入(ru)(ru)(ru)機(ji)(ji)(ji)前或(huo)機(ji)(ji)(ji)后卷取(qu)爐進(jin)行保溫方式(shi)，因此既減少了軋(ya)(ya)(ya)(ya)件(jian)的(de)(de)溫降(jiang)，也(ye)(ye)可(ke)使軋(ya)(ya)(ya)(ya)件(jian)在(zai)卷取(qu)爐與軋(ya)(ya)(ya)(ya)機(ji)(ji)(ji)之(zhi)間形成(cheng)(cheng)張力，進(jin)而(er)可(ke)減小軋(ya)(ya)(ya)(ya)件(jian)縱向的(de)(de)變形抗力。由于卷軋(ya)(ya)(ya)(ya)鋼(gang)板(ban)具有(you)上(shang)述特點，因而(er)可(ke)使軋(ya)(ya)(ya)(ya)件(jian)軋(ya)(ya)(ya)(ya)得更薄，并(bing)能得到較好的(de)(de)板(ban)形。
3. 鋼卷(juan)軋制(zhi)方式
這(zhe)種方式(shi)用(yong)于軋(ya)(ya)制商(shang)品鋼(gang)(gang)卷(juan)(juan)(juan)(juan)。采用(yong)出、入口卷(juan)(juan)(juan)(juan)取(qu)爐，將軋(ya)(ya)件往復軋(ya)(ya)至厚(hou)2.5～20.0毫米(mi)的(de)帶鋼(gang)(gang)，經層(ceng)流冷(leng)卻后進入地(di)(di)下卷(juan)(juan)(juan)(juan)取(qu)機卷(juan)(juan)(juan)(juan)成(cheng)鋼(gang)(gang)卷(juan)(juan)(juan)(juan)。綜合了(le)熱(re)連(lian)軋(ya)(ya)機和中(zhong)厚(hou)板(ban)軋(ya)(ya)機的(de)技(ji)(ji)術(shu)(shu)特(te)點，形成(cheng)了(le)現代卷(juan)(juan)(juan)(juan)軋(ya)(ya)中(zhong)厚(hou)板(ban)軋(ya)(ya)機的(de)技(ji)(ji)術(shu)(shu)特(te)色。采用(yong)的(de)主(zhu)要技(ji)(ji)術(shu)(shu)有：直接(jie)熱(re)裝技(ji)(ji)術(shu)(shu)，最高(gao)(gao)可(ke)達到75％；爐卷(juan)(juan)(juan)(juan)軋(ya)(ya)制工藝技(ji)(ji)術(shu)(shu)；控制軋(ya)(ya)制及(ji)熱(re)機軋(ya)(ya)制工藝技(ji)(ji)術(shu)(shu)（可(ke)滿足生(sheng)產(chan)管線鋼(gang)(gang)、高(gao)(gao)強度造船(chuan)板(ban)、高(gao)(gao)強度結構鋼(gang)(gang)板(ban)的(de)要求(qiu)）；高(gao)(gao)精度、快(kuai)速動態自(zi)動厚(hou)度控制技(ji)(ji)術(shu)(shu)（AGC）；板(ban)形控制（目(mu)前僅限(xian)于軋(ya)(ya)輥(gun)彎輥(gun)）技(ji)(ji)術(shu)(shu)；控制冷(leng)卻及(ji)層(ceng)流冷(leng)卻＋加速冷(leng)卻技(ji)(ji)術(shu)(shu)；全液壓(ya)地(di)(di)下卷(juan)(juan)(juan)(juan)取(qu)機及(ji)自(zi)動踏步控制技(ji)(ji)術(shu)(shu)等。
