目前卷軋中厚(hou)板軋機的(de)主要有(you)以下三(san)種種生產工藝：
1. 單(dan)張鋼板往復軋(ya)制方式
這(zhe)種方(fang)式主要用于軋制(zhi)厚(hou)度(du)大于20毫米(mi)(mi)的厚(hou)鋼(gang)板(ban)(ban)，使用較長的板(ban)(ban)坯，當軋制(zhi)到目標鋼(gang)板(ban)(ban)厚(hou)度(du)時，最(zui)終長度(du)大于50米(mi)(mi)（一般不(bu)超過100米(mi)(mi)），軋件直(zhi)接從出口卷取爐下面送至轉鼓飛剪，將之(zhi)剪切成倍(bei)尺(chi)母板(ban)(ban)長度(du)；通過加速冷(leng)卻后進入熱矯直(zhi)機及冷(leng)床；最(zui)后經精整線剪切出定尺(chi)成品(pin)鋼(gang)板(ban)(ban)。這(zhe)種方(fang)式適(shi)于常(chang)規的中(zhong)厚(hou)板(ban)(ban)生產工藝。
2. 卷軋鋼板方式
這(zhe)種方式(shi)主(zhu)要用(yong)(yong)于(yu)軋(ya)(ya)制生(sheng)(sheng)產(chan)厚(hou)(hou)度不超(chao)過(guo)20毫(hao)米(mi)的中厚(hou)(hou)鋼(gang)板(ban)(ban)。使(shi)用(yong)(yong)較長(chang)板(ban)(ban)坯，先在(zai)軋(ya)(ya)機(ji)上經(jing)反復可(ke)逆軋(ya)(ya)制，當(dang)軋(ya)(ya)件(jian)厚(hou)(hou)度不超(chao)過(guo)25毫(hao)米(mi)時(shi)，長(chang)軋(ya)(ya)件(jian)進(jin)入(ru)軋(ya)(ya)機(ji)入(ru)口(kou)或出口(kou)卷(juan)(juan)取(qu)爐進(jin)行保溫，經(jing)往復軋(ya)(ya)制，最(zui)終軋(ya)(ya)至成(cheng)品厚(hou)(hou)度；然后(hou)從(cong)出口(kou)卷(juan)(juan)取(qu)爐下面送往飛剪剪切成(cheng)長(chang)度不超(chao)過(guo)50米(mi)的母板(ban)(ban)，再經(jing)熱(re)矯直機(ji)矯直，冷床冷卻，在(zai)精整線剪切成(cheng)定尺(chi)長(chang)度鋼(gang)板(ban)(ban)。這(zhe)種生(sheng)(sheng)產(chan)工藝(yi)是卷(juan)(juan)軋(ya)(ya)中厚(hou)(hou)板(ban)(ban)軋(ya)(ya)機(ji)特有的生(sheng)(sheng)產(chan)工藝(yi)。卷(juan)(juan)軋(ya)(ya)板(ban)(ban)生(sheng)(sheng)產(chan)方式(shi)既(ji)不同于(yu)普通(tong)中板(ban)(ban)生(sheng)(sheng)產(chan)方式(shi)，也(ye)不同于(yu)熱(re)連軋(ya)(ya)鋼(gang)卷(juan)(juan)生(sheng)(sheng)產(chan)方式(shi)。由于(yu)其采用(yong)(yong)的是當(dang)軋(ya)(ya)件(jian)軋(ya)(ya)至厚(hou)(hou)度不超(chao)過(guo)25毫(hao)米(mi)，長(chang)軋(ya)(ya)件(jian)進(jin)入(ru)機(ji)前或機(ji)后(hou)卷(juan)(juan)取(qu)爐進(jin)行保溫方式(shi)，因此既(ji)減少了軋(ya)(ya)件(jian)的溫降，也(ye)可(ke)使(shi)軋(ya)(ya)件(jian)在(zai)卷(juan)(juan)取(qu)爐與軋(ya)(ya)機(ji)之間(jian)形成(cheng)張力，進(jin)而可(ke)減小軋(ya)(ya)件(jian)縱向的變(bian)形抗力。由于(yu)卷(juan)(juan)軋(ya)(ya)鋼(gang)板(ban)(ban)具有上述特點(dian)，因而可(ke)使(shi)軋(ya)(ya)件(jian)軋(ya)(ya)得(de)更薄，并能(neng)得(de)到(dao)較好的板(ban)(ban)形。
3. 鋼卷軋制方式
這種(zhong)方式用于軋(ya)(ya)制(zhi)(zhi)商品鋼(gang)(gang)卷(juan)(juan)(juan)。采(cai)用出、入口(kou)卷(juan)(juan)(juan)取(qu)爐，將軋(ya)(ya)件往復軋(ya)(ya)至厚(hou)2.5～20.0毫米的(de)(de)(de)帶鋼(gang)(gang)，經層流冷卻(que)(que)后進(jin)入地下(xia)卷(juan)(juan)(juan)取(qu)機(ji)(ji)卷(juan)(juan)(juan)成鋼(gang)(gang)卷(juan)(juan)(juan)。綜合(he)了熱(re)連軋(ya)(ya)機(ji)(ji)和中厚(hou)板(ban)軋(ya)(ya)機(ji)(ji)的(de)(de)(de)技(ji)術(shu)特點，形成了現(xian)代卷(juan)(juan)(juan)軋(ya)(ya)中厚(hou)板(ban)軋(ya)(ya)機(ji)(ji)的(de)(de)(de)技(ji)術(shu)特色。采(cai)用的(de)(de)(de)主要(yao)技(ji)術(shu)有：直接(jie)熱(re)裝技(ji)術(shu)，最高(gao)可達(da)到75％；爐卷(juan)(juan)(juan)軋(ya)(ya)制(zhi)(zhi)工藝(yi)技(ji)術(shu)；控(kong)(kong)制(zhi)(zhi)軋(ya)(ya)制(zhi)(zhi)及熱(re)機(ji)(ji)軋(ya)(ya)制(zhi)(zhi)工藝(yi)技(ji)術(shu)（可滿足生產管(guan)線鋼(gang)(gang)、高(gao)強度造船板(ban)、高(gao)強度結構鋼(gang)(gang)板(ban)的(de)(de)(de)要(yao)求(qiu)）；高(gao)精度、快速(su)動態自(zi)動厚(hou)度控(kong)(kong)制(zhi)(zhi)技(ji)術(shu)（AGC）；板(ban)形控(kong)(kong)制(zhi)(zhi)（目前僅限(xian)于軋(ya)(ya)輥彎輥）技(ji)術(shu)；控(kong)(kong)制(zhi)(zhi)冷卻(que)(que)及層流冷卻(que)(que)＋加速(su)冷卻(que)(que)技(ji)術(shu)；全(quan)液(ye)壓地下(xia)卷(juan)(juan)(juan)取(qu)機(ji)(ji)及自(zi)動踏步控(kong)(kong)制(zhi)(zhi)技(ji)術(shu)等。
