Abstract

The utility model discloses a vertical roll pass for reducing the intermediate process scratch of a steel belt, which comprises an upper lateral wall and a lower lateral wall, wherein the vertical roll pass is in an asymmetric structure, and the pitch of the upper lateral wall is smaller than that of the lower lateral wall; and the outer chamfering center of the lower lateral wall is aligned with the upper surface of an inlet guide device installed in front of the vertical roll pass. The utility model avoids the scratch formed due to the friction between the steel belt and the inlet guide device and improves the product quality.

Description

A kind of edger roll pass that reduces the scuffing of steel band pilot process

Technical field

The utility model relates to a kind of roll pass of field of metallurgy, specifically a kind of pass that reduces the scuffing of steel band pilot process.

Background technology

Ribbon steel vertical miller pass is symmetrical pass at present.Before pass, be provided with and make rolled piece enter the entrance of pass guide and guard smoothly.In the steel band operation of rolling, edger roll import guide and guard meeting causes scuffing to rolled piece.

Summary of the invention

In order to overcome the problem that ribbon steel vertical miller pass exists in the prior art, the purpose of this utility model provides a kind of pass that the steel band pilot process scratches that reduces, and this pass has been avoided between steel band and the import guide and guard owing to the scuffing that rubs and form.

The purpose of this utility model is achieved through the following technical solutions:

A kind of edger roll pass that reduces the scuffing of steel band pilot process comprises upper side wall and lower wall, and it is characterized in that: this edger roll pass is a unsymmetric structure, and the gradient of described upper side wall is less than the gradient of lower wall; And the outer chamfering center of the lower wall import guide and guard upper surface preceding with being installed in the edger roll pass aligns.

For making things convenient for rolled piece to nip, the outer chamfering of pass lower wall described in the utility model is greater than the outer chamfering of pass upper side wall.

The utility model is designed to the edger roll pass asymmetric, the upper side wall gradient that is pass is little, the lower wall gradient is big, and the upper and lower outer chamfering of pass is different, and when edger roll import guide and guard were installed, the upper surface of import guide and guard and the lower wall of pass be the chamfering center-aligned outward like this, make steel band when nipping, enter pass along the import guide and guard, in case form rolling after, steel band is then thrown off the import guide and guard, has avoided between steel band and the import guide and guard because the scuffing that friction forms.

Compared with prior art, the utility model has been stopped the scuffing between steel band and the import guide and guard, has improved product quality.During the utility model is applicable to that ribbon steel is rolling.

Description of drawings

Fig. 1 is the structural representation of the utility model when rolled piece is nipped;

Fig. 2 is the structural representation of the utility model when rolling.

The specific embodiment

The edger roll pass that a kind of minimizing steel band pilot process described in the utility model scratches is seen Fig. 1, and this edger roll pass comprises upper side wall 1 and lower wall 2, and this edger roll pass is a unsymmetric structure, and the gradient of upper side wall 1 is less than the gradient of lower wall 2; And lower wall 2 outer chamfering centers import guide and guard 3 upper surfaces preceding with being installed in the edger roll pass align.

For making things convenient for rolled piece to nip, pass lower wall 2 outer chamferings are greater than pass upper side wall 1 outer chamfering.Like this when edger roll import guide and guard 3 are installed, the upper surface of import guide and guard 3 and the lower wall of pass 2 outer chamfering center-aligned, make steel band 4 when nipping, enter pass along import guide and guard 3, in case form rolling after, 4 of steel bands are thrown off import guide and guard 3, have avoided between steel band 4 and the import guide and guard 3 because the scuffing that friction forms.Fig. 1 is the structural representation of the utility model when rolled piece is nipped; Fig. 2 is the structural representation of the utility model when rolling.

The utility model is stopped in the steel band operation of rolling by the improvement of opposite roller pass design, and edger roll import guide and guard have improved product quality to the scuffing of rolled piece.

Claims

1. one kind is reduced the edger roll pass that the steel band pilot process scratches, and comprises upper side wall (1) and lower wall (2), and it is characterized in that: this edger roll pass is a unsymmetric structure, and the gradient of described upper side wall (1) is less than the gradient of lower wall (2); And the outer chamfering of lower wall (2) center import guide and guard (3) upper surface preceding with being installed in the edger roll pass aligns.

2. the edger roll pass that minimizing steel band pilot process according to claim 1 scratches, it is characterized in that: the outer chamfering of described pass lower wall (2) is greater than the outer chamfering of pass upper side wall (1).
