Description

Technical Field

[0001] The utility model relates to the technical field of rolling mill groove rolling equipment, in particular to a rolling mill groove rolling double-layer water retaining device. Background Art

[0002] During the steel rolling process, the rolling groove is in close contact with the high-temperature rolled piece and the temperature rises quickly. High-pressure water must be used to cool the rolling groove. However, when the cooling water of the rolling groove flows to the rolled piece, the local temperature is reduced, which reduces the local ductility of the rolled piece, causing a series of problems such as blackheads on the head and cluster cracks in some steels with high carbon content. The cooling water pipes of the rolling groove of the vertical rolling mill are installed on both sides of the rollers. The cooling water of the rolling groove will reduce the cooling temperature of the corners of the rolled piece. The cooling water pipe on the roller of the horizontal rolling mill is located directly above the rolling groove. The cooling water falls naturally and pours onto the rolled piece through the gap between the exit sliding guide and the roller. In order to prevent the cooling water from pouring onto the rolled piece, a rubber skin is generally added above the exit sliding guide to cover the gap between the roller and the roller to prevent the cooling water from pouring onto the rolled piece through the gap. However, after a period of use, the rubber skin is baked brittle by the high-temperature rolled piece and worn by friction with the rolling groove, and it is impossible to prevent the cooling water from pouring onto the rolled piece.

[0003] Therefore, a double-layer water retaining device for a rolling mill groove is provided to solve the above-mentioned problem. Summary of the invention

[0004] The technical problem to be solved by the utility model is that, in the prior art, in order to prevent cooling water from pouring onto the rolled piece, a rubber skin is generally added above the exit sliding guide to block the gap between the roller and the roller to prevent cooling water from pouring onto the rolled piece through the gap. However, after a period of use, the rubber skin is baked brittle by the high-temperature rolled piece and worn by friction with the rolling groove, and it is impossible to prevent cooling water from pouring onto the rolled piece. Therefore, a rolling mill groove double-layer water retaining device is provided, and the rolling mill groove double-layer water retaining device comprises:

[0005] The double-layer water retaining device for the rolling mill groove is fixedly installed on the outlet sliding guide, and the double-layer water retaining device for the rolling mill groove includes: a box body, one end of the box body is fixedly connected to the outlet sliding guide by bolts, the other end of the box body is provided with a folded edge, and the folded edge extends toward the roller, and an air inlet joint is provided on the side of the end of the box body close to the outlet sliding guide, and an air path main body is provided inside the box body and the folded edge, and the air inlet joint is communicated with the air path main body, and a locking mechanism is also provided on the folded edge, and the locking mechanism is used to clamp a non-metallic wear-resistant plate, and the non-metallic wear-resistant plate extends toward the roller.

[0006] Furthermore, the box body is arranged horizontally, and the folded edge and the box body are at a preset angle, and the preset angle is 15°.

[0007] Furthermore, a duckbill-type air outlet is provided at the end of the folded edge facing the roller, and the duckbill-type air outlet is communicated with the air path main body inside the folded edge.

[0008] Furthermore, the locking mechanism includes a 7-shaped clamping plate, which is fixedly mounted on the upper part of the end of the folded edge close to the box body. A locking hole is opened on the upper plate surface of the 7-shaped clamping plate, and a locking bolt is arranged in the locking hole.

[0009] Furthermore, the box body and the non-metallic wear-resistant plate are both in clearance fit with the rolling groove on the roller, and the clearance is 2 mm.

[0011] Furthermore, the box body is a stainless steel box body.

[0012] Furthermore, it also includes reinforcing ribs, which are used to connect the box body and the 7-shaped clamping plate.

[0013] The implementation of this utility model has the following beneficial effects:

[0014] The utility model utilizes non-metallic wear-resistant plates to block most of the cooling water. In addition, the application adopts a box and folded edge design, which can facilitate water conduction and purge the remaining cooling water.
