Description

technical field [0001] The invention relates to the technical field of metal material calendering processing equipment in the metallurgical industry, in particular to a method for uncoiling, trimming, splitting, leveling, finishing, sizing, and cladding of hot-rolled double-layer bimetallic composite plates and / or coils. Film and palletizing production lines. Background technique [0002] With the rapid development of global machinery manufacturing and the increasing precision and efficiency requirements of bimetallic composite calendering, metallurgical equipment has become numerically controlled, intelligent, and efficient, and most of them are special-purpose, especially after bimetallic composite coils and plates are hot-rolled. The specialization of the finishing line is extremely prominent, and most manufacturers avoid investing in bimetallic composite material equipment due to the difficulty of breaking through the technology, thus affecting the development of the met...

AI Technical Summary

Problems solved by technology

[0004] 1) It is not possible to complete the composite material coil and composite material plate separation on the same production line. Two special production lines are needed to complete it, resulting in high manpower and equipment investment and a large equipment footprint

[0005] 2) The existing production line cannot simultaneously level, finish and cut the upper and lower composite boards formed after the composite material roll is torn apart, and the production efficiency is low

[0006] 3) In the existing production line, after uncoiling and centering, the head is aligned first, and then the edge is trimmed and divided. Due to the different radius of curvature of the inner and outer composite plates of the composite material roll, the length after unrolling is not equal, resulting in the subsequent disc shearing cannot be carried out smoothly. This will lead to production stagnation, and even affect product quality, resulting in equipment damage

[0007] 4) After the existing production line is uncoiled, it is roughly centered before trimming, which makes it difficult for the center line of the disc shear opening to coincide with the center line of the strip, resulting in poor dimensional accuracy of the finished plate and reducing product quality

In addition, the width and thickness of the waste edge cut by the disc shears are relatively large, resulting in severe distortion of the edge material after shearing, making it difficult to recycle.

[0008] 5) The existing production line will pile up steel due to poor speed and insufficient tension, which will lead to production stagnation, even affect product quality, and cause equipment damage. At the same time, it cannot meet the extended processing requirements of subsequent processes

[0009] 6) The finished board is easy to scratch or wear the clad stainless steel surface in the process of palletizing and packaging, which seriously affects the application effect of stainless steel composite materials and reduces the surface quality of the product
