Description

Technical Field

[0001] The invention relates to the technical field of annealing devices, and in particular to an annealing device for aluminum and aluminum alloy-compounded steel composite strips. Background Art

[0002] Annealing is a metal heat treatment process, which means slowly heating the metal to a certain temperature, keeping it for a sufficient time, and then cooling it at an appropriate rate. In a broad sense, annealing is a heat treatment process for materials, including metal materials and non-metallic materials. Aluminum and aluminum alloy steel composite strips need to be annealed during the production process. The main purpose is to release stress, increase material ductility and toughness, and produce special microstructures. However, due to the long length and large area of ​​the strip, the metal strip plate occupies a large space.

[0003] Those skilled in the art have conducted research and improvements on this. For example, in a cold-rolled metal strip annealing device with application number 20220110790.9, the technical solution uses the rotation of the turntable to achieve a rotary motion mode, reducing the space occupied by the metal strip plate. However, the technical solution still has shortcomings. In the technical solution, the position of the heating coil is fixed, and the plate needs to be inserted into the coverage range of the heating coil in an arc shape, which makes the operation difficult.
