Angle steel rolling guide device

Abstract

The invention relates to the field of steel rolling in the steel industry and discloses an angle steel rolling guide device. The angle steel rolling guide device comprises a guide box. Vertical plates and an inlet guide plate are arranged on the left side and the right side of the guide box, the inlet guide plate is in a horn mouth shape, the vertical plates are vertically arranged on the two sides of the guide box, and the vertical plates and the guide box are integrally formed. Two supporting arms are arranged on the front side and the rear side of the guide box correspondingly. The middle portion of each supporting arm is connected with the guide box through a rotation shaft. The supporting arms are provided with vertical guide rollers, and the vertical guide rollers on the two supporting arms can be used in cooperation. Compressing springs are arranged on the parts, between the vertical guide rollers and the rotation shafts, of the supporting arms, one end of each compressing spring is connected with the corresponding supporting arm, and the other end of each compressing spring is connected with the guide box. A flat guide roller is arranged on the bottom of the guide box and can provide support for displacement of a steel piece in the guide box. The angle steel rolling guide device can reduce the problems of surface scratches, scars and the like on rolling pieces, and precise centering can be achieved.

Description

(1) Technical field [0001] The invention relates to the field of steel rolling in the iron and steel industry, in particular to an angle steel rolling guide device. (2) Background technology [0002] At present, the imported rolling guides used in the field of domestic angle steel production mostly use sliding guides, or three-roller up and down rolling guides. Among them, the sliding guide has the advantages of simple structure and convenient adjustment. Sliding friction occurs between them, and the rolled piece is at a high temperature above 1000°C. During the production process, the surface of the guide is easy to cause iron sheet sticking, resulting in scratches and iron sheeting on the surface of the rolled piece, resulting in quality defects such as scratches and scars on the surface of the finished product. Although the three-roller up and down rolling guide avoids the advantage of scratching the rolled piece, its stability is relatively poor, and it is easy to cause ...

[0002] At present, the imported rolling guides used in the field of domestic angle steel production mostly use sliding guides or three-roller up and down rolling guides. The sliding guides have the advantages of simple structure and convenient adjustment. Sliding friction occurs between them, and the rolled piece is at a high temperature above 1000°C. During the production process, the surface of the guide is easy to cause iron sheet sticking, resulting in scratches and iron sheeting on the surface of the rolled piece, resulting in quality defects such as scratches and scars on the surface of the finished product

The three-roller up and down rolling guide, although it avoids the advantage of scratching the rolled piece, its stability is relatively poor, and it is easy to cause quality defects such as the deflection angle of the finished product
