　　1、筒體的預彎

　　先(xian)在鋼板(ban)(ban)(ban)一端預(yu)彎，卷(juan)板(ban)(ban)(ban)機應逐漸升壓卷(juan)制鋼板(ban)(ban)(ban)，在卷(juan)制過程中，用(yong)樣(yang)板(ban)(ban)(ban)檢(jian)(jian)查(cha)(cha)預(yu)彎段情況，但不(bu)得過卷(juan)。按上游技(ji)術文件(jian)要(yao)求，在預(yu)彎段用(yong)樣(yang)板(ban)(ban)(ban)檢(jian)(jian)查(cha)(cha)，棱角度控制采用(yong)弦長等于1/6設(she)計內徑Di，且不(bu)小于300 mm的(de)內樣(yang)板(ban)(ban)(ban)檢(jian)(jian)查(cha)(cha)，圓弧處(chu)與樣(yang)板(ban)(ban)(ban)之間的(de)間隙(xi)應≤2 mm，一端預(yu)彎合格后預(yu)彎另一端。卷(juan)制過程中，卷(juan)板(ban)(ban)(ban)機升壓數據(ju)(ju)壓力表數值及用(yong)樣(yang)板(ban)(ban)(ban)檢(jian)(jian)查(cha)(cha)數據(ju)(ju)記錄(lu)妥。

　　2、筒體的卷制

　　卷(juan)圓(yuan)時鋼板(ban)(ban)在上(shang)下輥之間放正，板(ban)(ban)材邊(bian)緣與(yu)輥筒(tong)軸(zhou)(zhou)線(xian)應(ying)嚴格(ge)保持平行。采用(yong)將板(ban)(ban)上(shang)的(de)標(biao)(biao)記與(yu)輥軸(zhou)(zhou)線(xian)上(shang)的(de)劃(hua)線(xian)標(biao)(biao)記對正來(lai)保證。卷(juan)制(zhi)(zhi)筒(tong)節(jie)時，逐次(ci)減少筒(tong)體(ti)的(de)曲率半徑(jing)，進行多次(ci)卷(juan)板(ban)(ban)成(cheng)型(xing)。卷(juan)制(zhi)(zhi)過程中用(yong)樣板(ban)(ban)控制(zhi)(zhi)卷(juan)制(zhi)(zhi)量(liang)和調(diao)離卷(juan)板(ban)(ban)機，控制(zhi)(zhi)過卷(juan)及每一次(ci)卷(juan)圓(yuan)的(de)變形量(liang)控制(zhi)(zhi)在總變形時的(de)30%。卷(juan)制(zhi)(zhi)完成(cheng)后用(yong)等離子切割去(qu)除一端(duan)(duan)預彎端(duan)(duan)。
