Description

Technical Field

[0001] The utility model relates to the technical field of metallurgy, and particularly relates to a side loop for steel rolling. Background Art

[0002] Side loops are widely used in high-speed wire rod rolling lines. During the steel rolling process, after the head of the steel material enters the downstream stand, the loop is lifted by the loop forming wheel to make the second flow rate equal between each stand, so as to achieve tension-free rolling, eliminate the tension caused by the accumulation or tension of the steel between adjacent rolling mills, and achieve tension-free rolling between the front and rear stands.

[0003] The existing side loop structure, such as the side loop outlet device disclosed in the Chinese patent with the publication number CN203197014U, can reduce the scratching of high-speed wire rod products at the outlet. However, in many practical scenarios, if the adjustment parameters of the loop forming wheel are unreasonable, the steel material is likely to collide with the inner wall of the side loop during loop forming, resulting in scratching.

The buffer roll 7 can contact the steel material 2 after looping.

[0024] The purpose of such a design is that by arranging a buffer roll inside the side loop body, it can effectively prevent the steel material after looping from contacting the inner wall of the side loop body, thereby reducing the probability of the steel material being scratched, and solving the problem that in many practical scenarios of the existing side loop, if the adjustment parameters of the looping roll are unreasonable, the steel material is prone to collide with the inner wall of the side loop and cause scratches during looping.

[0025] In this embodiment, the looping roll 5 is arranged at the bottom of the side loop body 1, and the buffer roll 7 is arranged at the top of the side loop body 1.
