Equipment Level It adopts the UCM-type single-stand 6-roll reversible cold rolling mill. The work roll of the rolling mill is equipped with positive and negative bending. The intermediate roll is equipped with positive bending and twitch. The uncoiler is equipped. Both front and rear frames are equipped with coiler, thickness gauge, laser velocimeter etc., which can realize large tension rolling and guarantee high-speed and stable production with specified thinness.1450 6-roll reversible cold rolling unit is the cold rolling production line with designed annual output of 225 thousand tons and adopts UCM-type single-stand mill. Roll 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, double-laser velocimeter, etc. 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 (company's utility model patent: ZL201120139812.6);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. 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. Imported X-ray thickness gauge is adopted, improving the thickness precision of finished strips.6. Imported laser velocimeter is adopted to realize mass flow AGC control in combination with AGC system, with improved the yield of strips.7. The rolling mill adopts Simens S7-400 programmable controller, DC drive adopts 6RA70 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.8. 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.9. In the second-level automation controlled by AGC, rolling schedule is further improved.10. All key components and parts of hydaulic system adopt import components and parts, which improves system reliability.11. Hydaulic AGC system is equipped with advanced functions of constant roll gap control, constant roll force control, constant thickness control, mass flow control, thickness precontrol, tension/speed automatic control, etc.5.
