Product Description 4-Roll Reversing Cold Rolling MillNote: We can design the machine according to your requirements!1.Brief IntroductionThe 4-roll reversing cold rolling mill will carry out finish rolling of stainless steel coils with material thickness of 2.5-3.25mm. After several passes of rolling, it will be rolled into high-precision cold-rolled steel coils of 0.5-1.95mm, using a single-stand reversible four-roll cold rolling mill to ensure high-speed and stable production of thin gauge products.Characteristics of the Cold Rolling Mill4 High reversing cold rolling mill is the cold rolling production line which adopts UCM-type single-stand mill. It rolls pickled hot rolled coils into cold hard coils. The unit is equipped with hydraulic AGC. The work roll is equipped with positive and negative bending and subsection cooling. The intermediate roll is equipped with the positive bending and moving, and the front and rear frames are equipped with double X-ray thickness gauge, etc. its Characteristics: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;3.Positive and negative bending of the work roll; the intermediate roll has transverse moving presetting, locking, and positive bending control measure. The bending roll can be controlled from single side; rollers are equipped with subsection cooling and roll shape adjustment. Multiple-plate-shape control measure is able to better control the plate shape of finished strips.4.Double-station roll changing carriage is adopted, which realizes the swift changing between the work roll and the intermediate roll.5.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.6.X-ray thickness gauge is adopted, improving the thickness precision of finished strips.7.The whole control system of the Six-High CRM adopts full digital AC driving devices, PLC Unit process control and remote communication network technology. The power supply and distribution, AC and AC motor control, PLC system, remote I / O system, AGC system and human machine interface (HMI) are integrated through two-level network. In the design, the interfaces between each system are designed in a unified way, so as to form the whole automatic control system of modern CRM.8.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.9.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.10.In the second-level automation controlled by AGC, rolling schedule is further improved.11.All key components and parts of hydraulic system adopt import components and parts, which improves system reliability.12.Hydraulic AGC system is equipped with advanced functions of constant roll gap control, constant roll force control, constant thickness control, mass flow control, thickness pre-control, tension/speed automatic control, etc. 2.
