Description

Technical Field

[0001] The utility model relates to the technical field of strip steel cold rolling equipment, and more specifically to an online adjustment and deviation correction pressure roller mechanism. Background Art

[0002] In the pickling cold rolling mill, the problem of the tail edge overflow is a difficult technical problem to solve. When the steel coil enters the flat cover furnace, the overflow edge part is wrinkled and must be cut off before entering the leveling machine. This process will waste a lot of semi-finished strip steel. The control of the overflow edge lies in the roller on the curling plate. The parallelism of the installation of the roller is very important, but the polyurethane material of the roller body is not wear-resistant. As the roller body wears, the installation accuracy decreases, and the tail edge overflow cannot be controlled. Adjustment requires shutdown and high altitude, which takes a long time and is also dangerous. Therefore, in view of this, the existing structure is studied and improved, and an online adjustment and correction roller mechanism is provided to achieve a more practical purpose.
