Embodiment 1
[0016] Embodiment 1 The method for improving the finishing temperature of can body material
[0017] In this embodiment, a five-stand cold tandem rolling mill is used to roll 3104 can body materials. The thickness of the hot-rolled coil is 2.5 mm, the thickness of the finished coil is 0.275 mm, and the width is 1250 mm. The working roll diameter of the five stands is 470-508mm, the length of the roll body is 1727mm, the diameter of the backup roll is 1092-1168mm, the length of the roll body is 1626mm, and the temperature of the water-based coolant is 58°C. Water-based coolant (supplied by French Total) is used for lubrication, and the ratio of oil in the water-based coolant, nozzle injection pressure, water-based coolant flow rate and reduction rate in the five racks are controlled, as shown in Table 1. Show. The speed of the fifth frame is 1350m / min.

Embodiment 2
[0028] Embodiment 2 The method for improving the finish rolling temperature of can body material
[0029] In this embodiment, a five-stand cold tandem rolling mill is used to roll the can body material. The thickness of the hot-rolled coil is 2.3 mm, the thickness of the finished coil is 0.272 mm, and the width is 1550 mm. The working roll diameter of the five stands is 470-508mm, the length of the roll body is 1727mm, the diameter of the support roll is 1092-1168mm, the length of the roll body is 1626mm, and the temperature of the water-based cooling liquid is 60°C. Water-based coolant is used for lubrication, and the ratio of oil in water-based coolant, nozzle injection pressure, water-based coolant flow rate and reduction rate are controlled in five racks, as shown in Table 4. The speed of the fifth frame is 1380m / min.
