Description

Technical Field

[0001] The utility model belongs to the technical field of rolling, and particularly relates to a novel water retaining device. Background Technique

[0002] During the rolling of rolled materials at present, the temperature of the rolled materials when they come out of the furnace is generally above 1000°C. To protect the rough rolling rolls, high-pressure water is needed to cool them.

[0003] At present, the following problems exist in the rough rolling parallel rolling mills:

[0004] 1) After the cooling water of the upper roll is sprayed from top to bottom onto the roll surface, it will flow onto the surface of the rolled material. There is a temperature difference on the same surface of the rolled material, the deformation resistance increases, the thermal stress on the surface of the rolled material is large, surface cracks are generated, and the strip shape is difficult to control.

[0005] 2) The temperature drop on the upper surface of the rolled material is too large (more than 40°C), the temperature of the upper and lower surfaces is uneven, and the deformation of the lower surface is larger than that of the upper surface during the subsequent rolling, which may cause the rolled material to warp and cannot enter the next pass, easily resulting in production accidents.

[0006] 3) The cooling water is sprayed on the guide assembly. The assembly is easily rusted when exposed to high temperature and humid environment for a long time, and it is not easy to disassemble and assemble later.

[0007] 4) If a simple water baffle is used, the working surface cannot fit seamlessly with the rolling groove, and there will still be cooling water flowing towards the rolled material.

[0008] 5) Using a simple water baffle is easy to be damaged and it is inconvenient to replace the rolling groove. Content of the Utility Model

[0009] The purpose of the utility model is to provide a novel water retaining device. By designing a composite water retaining edge composed of a steel plate, a flexible water sealing strip and a cotton curtain, and arranging a flange part matching the rolling groove hole shape on the front side of the water baffle body, it is used to block the cooling water sprayed and splashed from the upper roll to the upper surface of the rolled material, so as to improve the effectiveness of the water retaining device, reduce the non-process temperature drop caused by the water accumulation on the surface of the rolled material, improve the surface quality of the rolled material, and reduce the incidence of production accidents.

[0010] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0011] The utility model is a novel water retaining device, which includes a rough rolling roll, a guide assembly and a water baffle mechanism. The rough rolling roll is provided with a rolling groove;

[0012] The water baffle mechanism includes a water baffle body and a group of support feet;

[0013] A flange part matching the rolling groove is arranged on the front side of the water baffle body, and notch parts are formed between both sides of the flange part and both sides of the water baffle body;

[0014] The water baffle body is arranged outside the rough rolling roll, the flange part clearance is arranged in the rolling groove, and a clearance for yielding with a consistent spacing is formed between the flange part and the notch part and the outer wall of the rough rolling roll;

[0015] Flexible edge strips are fixed to the front sides of the flange part and the notch part, and the water baffle body is in interference fit with the rough rolling roll through the flexible edge strips;

[0016] One end of a group of the support feet is rotatably connected to the rear side of the water baffle body through a front hinge, and the other end of the group of the support feet is rotatably connected to the top of the guide assembly through a rear hinge.

[0017] Furthermore, a cotton seal is fixed to the front side of the upper surface of the water baffle body. The cotton seal is in the shape of a curtain and covers above the clearance for yielding, and the edge of the cotton seal is attached to the outer wall of the rough rolling roll.

[0018] Furthermore, both ends of the cotton seal are flush with the two side edges of the water baffle body respectively, and the spacing between the cotton seal and the flange part and the notch part is consistent.

[0019] Furthermore, the two support feet are distributed in parallel, and the support feet and the water baffle body are distributed perpendicularly.

[0020] Furthermore, when the upper surface of the support feet is flush with the upper surface of the water baffle body, the two blades of the front hinge are in a parallel state, and the front end face of the support feet is attached to the rear side face of the water baffle body.
