Problems solved by technology

However, the performance of the strip produced by the existing aluminum processing technology is not good, and the thickness, roughness, and flatness of the sheet cannot be guaranteed, which will directly affect the surface coloring, corrosion resistance, and rigidity of the subsequent sheet, and cannot meet production needs.

Embodiment Construction

[0019] The technical solution of the present invention is, an EDT surface rolling method for an aluminum strip, which includes the following steps: S1: establishing an EDT rolling mode; S2: setting a constant rolling force; S3: de-tensioning roller; S4: rolling Force and texture roughness conversion.

[0020] In the solution of the present invention, in the step S1, the EDT rolling mode includes an EDT rolling system, and the EDT rolling system includes an uncoiler 1, a deflector roll 2, a plate roll 3 and a coiler 4. The deflector roll There is a CVC six-high rolling mill 9 between the guide roll 2 and the profile roll 3. The aluminum sheet is transported to the CVC six-high rolling mill 9 through the uncoiler 1 and the deflector roll 2. After being rolled by the CVC six-high rolling mill 9, it is passed through the profile roll. 3 and the coiler 4 are reeled. In the EDT rolling mode, the minimum rolling force protection of the pressing cylinder is set from 1000KN to 500KN, i...

Abstract

The invention discloses an EDT surface rolling method for an aluminum plate strip. The EDT surface rolling method comprises the following steps that S1, an EDT rolling mode is established; s2, constant rolling force is set; s3, removing a tensioning roller; s4, rolling force and texturing roughness conversion is conducted, in the step S1, an EDT rolling system is included in the EDT rolling mode, the EDT rolling system comprises an uncoiler, a deflector roller, a plate type roller and a coiler, a CVC six-roller mill is arranged between the deflector roller and the plate type roller, and an aluminum plate is conveyed to the CVC six-roller mill through the uncoiler and the deflector roller, rolled through the CVC six-roller mill and then wound through the plate type roller and the coiler; the EDT plate produced through the aluminum plate strip EDT surface rolling method is uniform in surface roughness, free of obvious twill and flat in plate shape, the product quality can be improved conveniently, and the production requirement is met.

Description

technical field [0001] The invention relates to the technical field of aluminum sheet rolling, in particular to an EDT surface rolling method for an aluminum sheet and strip. Background technique [0002] Different from traditional vehicles, new energy vehicles use new energy as power to drive the vehicle. Restricted by the weight of the power battery and the cruising range of the power battery, in terms of vehicle design and material application, the lightweight of the car body has become the first consideration for car companies. The problem. If lightweight technology is used on new energy vehicles, the body weight can be reduced by 10%, the power consumption can be reduced by 5.5%, and the cruising range can be increased by 5.5%. [0003] The car body is one of the heaviest components in a car, accounting for about 30% of the total weight of the car. Aluminum alloys have a series of excellent properties, such as low density, high specific strength and specific stiffness...
