Product Description Coil Width 800mm Cold Rolling Mill Note: We can design the machine according to your requirements!1.Brief IntroductionThis cold rolling mill is to roll the steel coil with the thickness of 2.5mm to 4.0mm. Afterseveral pass rolling, it can be rolled into high-precision cold-rolled coil withthickness of 0.3mm to 1.8mm. It adopts single stand reversible four high coldrolling mill, which is equipped with a coiler with high tension and AGC thicknesscontrol system. It can realize high tension rolling and ensure the high-speedand stable production of thin products. The features:1) The electric control of rolling mill adopts Siemens AC drive technology. SiemensS7-400 series PLC products are used for automatic control2) The electric drive and automation system of rolling mill is with overloadprotection, belt breaking protection, emergency stop and other safetyprotection measures.The unit has the functions of automatic deceleration ofbelt tail, accurate stop, rolling process parameter setting, etc. the coilerhas the functions of coil number memory and belt length calculation. Theproduction process interlock and fault alarm of the unit are controlled bySiemens PLC to realize the automation of production process and fault alarm.3)The adjustment device of rolling line adopts the combination adjustment ofstepped wedge. The roll diameter inputting can quickly and automaticallycontrol the displacement of stepped wedge driven by oil cylinder to a properposition, so as to realize the automatic and rapid adjustment of rolling line.4)The gear of the reducer of the important driving equipment with heavy load,such as coiler and main rolling mill, is grinded with hard tooth surface; thebearing of the reducer of coiler and main rolling mill is of high quality withChina brand.5)Full hydraulic Screw down, hydraulic AGC automatic control. It has thefunctions of constant roll gap position control, constant pressure control,roll deviation adjustment, thickness pre control, monitoring, etc.6)Positive and negative bending of the work roll; the intermediate roll has transverse movingpresetting, locking, and positive bending control measure. The bending roll can be controlledfrom single side; rollers are equipped with subsection cooling and roll shape adjustment.Multiple-plate-shape control measure can better control the plate shape of finished strips.7)Double-station roll changing carriage is adopted, which realizes the swift changingbetween the work roll and the intermediate roll. 8)Roll system of the rolling mill, the turning roll, and the oil removal roll bearing adopt air-oillubrication, which can prolong the bearing's life and reduce oil consumption, pollution andmaintenance quantity with high lubrication efficiency. 2.Product ProgramStandard of coming materialMaterial quality pickled hot rolled strips Q195,Q235, SPCC, SPCD, SPCEThickness2.5mm to 4.0mmWidth400mm to 800mmRolling diameter(interior /exterior)Φ508/2200mm The maximum rolling weight18t Standard of finished products Thickness0.2-1.8mmWidth400-800mmRolling diameter(interior/exterior)Φ508/Φ2200mm The maximum rolling weight18tDrive mode: work roll driveMax. rolling speed: 600 m/min.
