Description

Built-in bearing type looper press roller

Technical Field

The utility model belongs to the technical field of rolling mills, and particularly relates to an embedded bearing type loop press roller.

Background

The loop is an important device in the finish rolling area of the bar production line. In order to ensure the dimensional accuracy of products, the modern high-speed bar rolling mill mostly adopts micro-tension or tension-free rolling to eliminate tension fluctuation and rolled piece dimensional fluctuation caused by various dynamic interferences in the rolling process. In order to solve the problem of fluctuation of the size of the rolled piece caused by tension change, a plurality of loops are arranged in a finishing mill group to eliminate the disturbance of dynamic speed change of each rolling mill piece. The speed of adjacent frames is regulated by an automatic control system, so that redundant rolled pieces are generated between the frames. The "extra" rolling stock is formed with the aid of a sleeve-lifting device and is able to dynamically maintain an arcuate sleeve-shape, called a loop.

The loop press roller is a critical component on the loop. In the current general design, the loop press roller is slotted and installed in the slot through the sleeve body, and both ends of the loop press roller are fixedly connected on the base through bearings. Therefore, the bearings on the two sides of the looper press roll are directly opposite to the impact of high temperature and cooling water of the rolled piece, and rust failure of the bearings is very easy to occur.
