 6 Roll Reversing Cold Rolling Mill Coil Width 1600mm
 

The cold rolling mill can work with pickled hot rolled coil of  thickness of 6mm, which is rolled into a high-precision cold-rolled steel coil of 0.4-4.5mm after several passes, using a single-stand reversible four-roll UCM cold rolling mill. The work rolls are provided with positive and negative bends, the intermediate rolls are provided with positive bending rolls and twitching, and the uncoiling machine and the front and back of the frame are provided with a tension coiler, a thickness gauge, a laser speedometer, etc., which can realize large tension rolling. Guarantee high-speed and stable production of thin gauge products.
 


Remark: We can customize the cold rolling mills according to your special  requirements. 
6 Roll Reversing Cold Rolling Mill Coil Width 1600mm

1.Uncoiler is equipped with CPC automatic centering function, which adopts EMG products from Germany, and improves the centering response speed and position control accuracy.
2.Rolling line adjustment equipment adopts stepwise wedge combination adjustment, and the input roll diameter can quickly and automatically control the stepwise wedge displacement of the oil cylinder drive to the right position, realizing automatic and quick adjustment of the rolling line (company's utility model patent:  ZL201120139812.6)
3. Work roll positive and negative bending roll; intermediate roll traverse pre-set, lock, and has positive bending roll control means, bending roll can be controlled separately on one side; roll section cooling roll type adjustment. A variety of plate type control methods can better control the shape of the finished strip.
4.Roll system of the rolling mill, the turning roll, and the oil removal roll bearing adopt air-oil lubrication, which can prolong the bearing's life and reduce oil consumption, pollution and maintenance quantity with high lubrication efficiency.
5.The rolling mill adopts Simens S7-400 programmable controller, DC drive adopts 6RA80 all-digit speed regulating system, and the electric system takes safety protection measures of overload protection, strip breakage protection, emergency cut-off, etc.; the unit is equipped with functions of strip tail automatic deceleration, accurate stopping and multi-point stopping; coiler is equipped with functions of cycle memory, strip length calculation, and jaw accurate positioning.
6.AGC automatic system adopts "S7-400+FM458" structure, which makes the utmost use of the controller and matches the quick response of the high-speed rolling mill.
7.All key components and parts of hydraulic system adopt import components and parts, which improves system reliability.
