Description

TECHNICAL FIELD

[0001] The utility model relates to aluminum processing technical field more specifically relates to a kind of movable heating device for improving the tight state of aluminum strip edge part. BACKGROUND

[0002] In the production process of aluminum strip, the tight state of aluminum strip edge part is one of the key factors affecting product quality and production efficiency. The tight state of aluminum strip edge part is usually caused by the temperature difference between the edge and the middle part during rolling, annealing and other processes, resulting in uneven distribution of thermal stress. When the roller temperature is low, the edge of the aluminum strip and the roller contact area dissipate heat faster, the temperature is further reduced, and the temperature difference between the edge and the middle part is aggravated, so that the edge generates greater tensile stress, forming a tight state.

[0003] This tight state will cause a series of problems: first, it will affect the flatness quality of the aluminum strip, causing edge wave, warping and other defects; second, the tight edge is prone to cracking during subsequent processing, affecting product yield; in addition, the tight state will also increase the rolling force, accelerate the wear of the roller and reduce the production efficiency.

[0004] Currently, the industry usually uses fixed heating device to heat the edge of aluminum strip to alleviate the tightness of the edge. However, fixed heating device has the disadvantages of poor flexibility, limited heating range, high energy consumption, etc., which is difficult to meet the production needs of aluminum strips of different specifications. In addition, the fixed heating device is usually installed at a specific location and cannot be adjusted flexibly according to the actual situation during production, resulting in unsatisfactory heating effect.
