Abstract: the invention belongs to the technical field of packaging steel strip production, in particular an automatic production line for producing high-strength color coated packaging steel strip by non quenching and tempering process, which includes the following equipment successively arranged in 2017 and 2018: Tension unwinding unit, strip welding machine, feeding leveler, storage bin, tension speed control s-roll unit Longitudinal shear unit, trimming machine, heating furnace, first and second cooling tanks, coating tank, coating drying furnace, wax or oil tank, drying tower, differential tension speed control s-roll unit, independent gravity looper unit, winding unit, packaging and transportation unit, automatic control system 3. Spring fatigue tester sheet metal: it is a protective layer system for the appearance of spring fatigue tester. The winding machine includes adjusting wheel, pressing wheel, nylon wheel, pneumatic shear Guide pulley, receiving drum and unloading trolley. This production line integrates the whole production process of high-strength color coated packaging steel strip into one production line. The metallographic structure of the steel strip is pearlite + ferrite. Compared with the existing domestic and foreign production lines of high-strength packaging steel strip ≥ 880mpa, the production line of the invention reduces the investment in equipment with the same capacity by 90% and the production cost per ton of steel strip by 40%

sovereignty item: 1. An automatic production line for producing high-strength color coated packaging steel strip by non quenching and tempering process, including feeding equipment, Slitting unit, coating equipment, independent gravity looper unit and finished product winding and packaging equipment, which is characterized in that the production line includes the following successively arranged equipment: tension winding unit, plate and strip welding machine, feeding and pressing roller, leveler, storage bin, tension speed control s-roll unit Longitudinal shear unit, trimming machine, heating furnace, the first cooling tank, coating tank, coating drying furnace, the second cooling tank, wax or oil tank, drying tower, differential tension speed control s-roll unit, independent gravity looper the European Central Bank announced to keep the interest rate unchanged and relax the monetary policy time limit, or it will extend the unit, winding unit, packaging unit. PLC and the control devices of each unit are connected to form a closed-loop control system of temperature and speed, The tension unwinding unit comprises a charging trolley under the discharging platform and a discharging device above the charging trolley on the discharging platform. The storage bin is composed of an inlet inclined vertical roll group, a storage bin body and an outlet inclined vertical roll group which are successively arranged. The outlet inclined vertical roll group is adjacent to the inlet of the tension speed control s roll unit, The longitudinal shearing unit is composed of an inlet idler, an adjusting device, a pressing roller, a longitudinal shearing machine, a trimming unit composed of a tension plate and two deburring machines in series, and an outlet steering roller
