Description

Technical Field

[0001] This utility model relates to the field of steel rolling technology, and in particular to a cooling device for steel rolling guides and a steel rolling guide. Background Technology

[0002] Rolling guides are devices installed before and after the roll passes during the section steel rolling process. They help the rolled workpiece enter and exit the roll passes accurately and stably according to a predetermined direction and state. Rolling guides include components such as guide plates, guide plate boxes, fixed crossbeams, guide tubes, torsion guide plates, torsion rolls, and positive and negative retaining plates. Among them, the guide rolls are in constant contact with the high temperature of red-hot steel during normal rolling. After prolonged operation, the surface quality and dimensional accuracy of the guide rolls will significantly decrease, affecting the quality of the rolled products.

[0003] To address the aforementioned issues, patent document CN218486875U discloses a guide roller cooling device. This device includes a guide roller body, a heat sink, and a cooling assembly. The heat sink is fixed to the side wall of the guide roller body. The cooling assembly includes a water tank, a water pump, a cooler, an outlet pipe, a U-shaped cooling pipe, and an inlet pipe. One end of the outlet and inlet pipes is connected to the water tank, and the other end is fixed to both ends of the U-shaped cooling pipe and connected to it. The water pump and cooler are both mounted on the outlet pipe, with the water pump located between the cooler and the water tank. A through hole is provided on the heat sink, through which the U-shaped cooling pipe passes and is fixed to the heat sink. Multiple ventilation slots are provided on the heat sink, communicating with the through hole, and are equidistantly distributed circumferentially along the inner wall of the through hole. This device uses ventilation grooves on the heat sink to allow gas to flow through the grooves due to the pressure difference between the inside and outside of the grooves. This helps to remove heat from the heat sink and improve its heat dissipation effect, thereby ensuring the cooling effect on the guide rollers.

[0004] As can be seen, the above-mentioned device can utilize a radiator to dissipate heat from the guide rollers. By opening ventilation slots on the radiator, the heat dissipation efficiency of the radiator is improved, achieving rapid cooling of the guide rollers. However, the complex structure of the above-mentioned device leads to high production costs, and the difficulty and cost of maintenance are also greatly increased, reducing the economic benefits of enterprises.

[0005] This utility model provides a cooling device for rolling mill guides and a rolling mill guide, in order to solve the technical problems of high production cost and difficult maintenance caused by the complex structure of existing guide roller cooling devices.

[0006] To solve the above problems, the cooling device for rolling mill guides provided by this utility model adopts the following technical solution:

[0007] A cooling device for a steel rolling guide includes an eccentric handle quick connector, a horizontal pipe, and a vertical pipe. The eccentric handle quick connector is installed on the horizontal pipe, and the angle between the eccentric handle quick connector and the horizontal pipe is an acute angle.

[0011] 3. The angle between the eccentric handle quick coupling and the horizontal tube is an acute angle, which can effectively reduce the space occupied by the cooling device for rolling mill guides.

[0012] This utility model has a simple structure, low cost, and is easy to assemble and disassemble, making it convenient for maintenance. While saving space, it can also ensure the cooling effect on the guide rollers, effectively solving the technical problems of high production costs and difficult maintenance caused by the complex structure of the existing guide roller cooling device.

[0013] Furthermore, both of the risers are perpendicular to the horizontal pipe.

[0014] Furthermore, the two ends of the horizontal tube are sealed, and each end of the horizontal tube has a connection port for connecting to the vertical tube on the inner side of the sealed end.

[0015] Furthermore, the horizontal pipe has openings at both ends, and the horizontal pipe is connected to the vertical pipe through a bend joint.

[0016] Furthermore, the horizontal tube and the vertical tube are integrally formed.

[0017] Furthermore, the top surface of the horizontal tube has a center opening for inserting the eccentric handle quick connector.

[0018] Furthermore, the center of the top surface of the horizontal tube is connected to an inclined upward extending mounting tube, the outer wall of the mounting tube has an external thread, and the inner wall of the eccentric handle quick connector has an internal thread that matches the external thread. The eccentric handle quick connector is screwed onto the mounting tube.

[0019] Furthermore, the outer periphery of the mounting tube is provided with a seal to enhance the sealing of the connection between the eccentric handle quick connector and the mounting tube.

[0020] Furthermore, the water delivery pipe is a stainless steel flexible metal hose.

[0021] To solve the above problems, the rolling mill guide provided by this utility model adopts the following technical solution:

[0022] A rolling mill guide includes a guide body, which includes guide rollers, and also includes the aforementioned cooling device for the rolling mill guide. The cooling device for the rolling mill guide is installed on the guide body, and the two vertical pipes are respectively located on two opposite sides of the guide rollers.

[0023] The beneficial effects of the rolling mill guide provided by this utility model are as follows: By installing a cooling device for the rolling mill guide on the main body of the guide, a water supply pipe can be connected through an eccentric handle-type quick connector, realizing quick connection and disconnection between the water supply pipe and the horizontal pipe, improving work efficiency, and ensuring the safety and convenience of the operation process; the combined design of the horizontal pipe and the vertical pipe allows the cooling water to be evenly and efficiently distributed around the rolling mill guide. The horizontal pipe serves as the main channel for cooling water, while the vertical pipe sprays cooling water directly to the parts that need cooling through the water outlet holes, thereby improving cooling efficiency; the angle between the eccentric handle-type quick connector and the horizontal pipe is an acute angle, which can effectively reduce the space occupied by the cooling device for the rolling mill guide.

[0024] Through the above-mentioned design, this utility model effectively solves the technical problems of high production costs and difficult maintenance caused by the complex structure of the guide roller cooling device in the prior art. Attached Figure Description
