Coiler Front Side Guide System for Hot Rolling Line

Abstract

The invention discloses a front-side guide plate system of a hot rolling wire reeling machine and relates to an auxiliary device of the hot rolling wire reeling machine. The front-side guide plate system comprises parallel-section guide plates and oblique-section guide plates, which are hinged with each other, wherein the parallel-section guide plates and the oblique-section guide plates consist of operating sides and driving sides, which are symmetrically distributed, and conveying roll ways are arranged between the operating sides and the driving sides; the operating sides and the driving sides of the parallel-section guide plates comprise guide plates, a plurality of vertical rolls, a plurality of transition guide plates, lining plates and driving devices, the vertical rolls are distributed on the guide plates along the extending directions of the guide plates, the transition guide plates are distributed on the inner sides of the guide plates along the extending directions of the guide plates, the lining plates are arranged on the inner sides of the guide plates along the extending directions of the guide plates, and the driving devices are arranged on the outer sides of the guide plates, are connected with the guide plates and synchronously move to drive the operating sides and the driving sides to move in parallel. According to the front-side guide plate system, the workload for exchanging the lining plates is effectively reduced, the service time of the lining plates is prolonged, the equipment consumption is reduced, and the product quality of a rolled black coil is improved.

Description

technical field [0001] The invention relates to an auxiliary device for a hot rolling line coiler. Background technique [0002] At present, the disadvantages of the side guide plate device of the same type of coiler at home and abroad are as follows: [0003] 1. The lining plate of the parallel section of the side guide plate wears out very quickly when the finished strip steel plate is poorly shaped and deviates. Basically, it must be replaced every 4 hours for surfacing repair, and the on-site workers have a lot of labor; [0004] 2. After the groove is worn out on the liner plate of the parallel section of the side guide plate, the natural round edge of the finished strip will have severe sliding friction on the upper or lower part of the groove, resulting in a large amount of filiform iron filings and iron oxide scale. These iron filings and iron oxide scales will be partially brought into the coiler and pressed into the surface of the steel plate to cause quality defe...

AI Technical Summary

Problems solved by technology

These iron filings and iron oxide scales will be partially brought into the coiler and pressed into the surface of the steel plate to cause quality defects;

[0005] 3. In order to control the coil shape (reduce the tower shape), the side guide plate will generate lateral thrust on the strip steel, especially the tail, but after the groove is worn out by the lining plate of the parallel section of the side guide plate, the edge of the strip steel will be stuck in the groove Quality defects that can cause flanging

[0006] 4. The design of the side guide plate lining plate cannot be turned over for use, which reduces the service life of the equipment
