Description

Technical Field

[0001] This utility model belongs to the technical field of water cooling equipment for steel profiles, and specifically relates to a cooling water pipe structure for H-beam steel rolls. Background Technology

[0002] Currently, the German SMS equipment commonly used in domestic steel profile production lines still employs the traditional "trapezoidal" structure for universal roll cooling. However, this roll cooling structure suffers from uneven roll cooling, leading to phenomena such as roll "loosening" and scaling, ultimately resulting in defects such as rounded corner folds, which seriously affect product quality and increase roll consumption. Utility Model Content

[0003] The purpose of this invention is to solve the above problems and provide a cooling water pipe structure for H-beam steel rolls.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A cooling water pipe structure for H-beam steel rolls includes two upper cooling structures and two lower cooling structures. The two upper cooling structures are symmetrically arranged on both sides above the upper roll ring, and the two lower cooling structures are symmetrically arranged on both sides below the lower roll ring. The positions of the upper cooling structures and the lower cooling structures are perpendicular to each other.

[0006] Furthermore, the upper cooling structure includes a first water inlet pipe, a U-shaped cooling water pipe, two first vertical water pipes, and several short nozzles. The U-shaped cooling water pipe is horizontally arranged on one side above the upper roller ring, with both sides located directly above the upper roller ring. The first water inlet pipe is vertically arranged in the middle of the top surface of the U-shaped cooling water pipe. The two first vertical water pipes are vertically arranged on the bottom surface of the two bends of the U-shaped cooling water pipe, and the first vertical water pipes are located on one side wall of the upper roller ring. The ends of the U-shaped cooling water pipe and the first vertical water pipes are sealed by first plugs. The several short nozzles are evenly arranged on the lower part of the U-shaped cooling water pipe and on the side of the first vertical water pipe facing the upper roller ring. The first water inlet pipe is connected to an external cooling water source.

[0007] Furthermore, the short nozzles on both sides of the U-shaped cooling water pipe are arranged vertically downwards, and the short nozzles in the middle of the U-shaped cooling water pipe and on the first vertical water pipe are arranged obliquely downwards.

[0008] Furthermore, the lower cooling structure includes a second water inlet pipe, a trapezoidal cooling water pipe, two second vertical water pipes, and several long nozzles. The second water inlet pipe is located on the middle side of the trapezoidal cooling water pipe and is connected to a cooling water source. The two second vertical water pipes are parallel to and symmetrically arranged on the two sides of the trapezoidal cooling water pipe, opposite to the second water inlet pipe. The two second vertical water pipes are located on both sides of the lower roller ring. The ends of the trapezoidal cooling water pipe and the second vertical water pipe are both sealed with second plugs. The several long nozzles are evenly arranged on the upper part of the trapezoidal cooling water pipe and on the side of the second vertical water pipe facing the lower roller ring.

[0009] Furthermore, the long nozzle in the middle of the trapezoidal cooling water pipe is set vertically upward, and the long nozzles on the two sides of the trapezoidal cooling water pipe and the second vertical water pipe are set obliquely upward.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model, through the combined action of the upper and lower cooling structures, can provide all-round cooling for the upper and lower roller rings, ensuring uniform cooling of all working surfaces of the roll, especially the roll rounded corners, thus avoiding phenomena such as roll chipping and scaling, and ensuring product quality.

[0012] 2. This utility model reduces the wear of the rolling mill rolls, reduces rolling mill roll consumption, and lowers production costs;

[0013] 3. This utility model eliminates the need for manual grinding of the rolls during the steel-passing process, thus reducing the workload. Attached Figure Description

The positions of the upper cooling structures 4 and the lower cooling structures 5 are perpendicular to each other.

[0022] The upper cooling structure 4 includes a first water inlet pipe 4.1, a U-shaped cooling water pipe 4.2, two first vertical water pipes 4.3, and several short nozzles 4.2. The U-shaped cooling water pipe 4.2 is horizontally arranged on one side above the upper roller ring 2, with both sides directly above the upper roller ring 2. The first water inlet pipe 4.1 is vertically arranged in the middle of the top surface of the U-shaped cooling water pipe 4.2. The two first vertical water pipes 4.3 are vertically arranged on the bottom surface of the two bends of the U-shaped cooling water pipe 4.2, and the first vertical water pipes 4.3 are located on one side wall of the upper roller ring 2. The ends of the cooling water pipe 4.2 and the first vertical water pipe 4.3 are both sealed by the first plug 4.4. The plurality of short nozzles 4.5 are evenly arranged on the lower part of the U-shaped cooling water pipe 4.2 and the side of the first vertical water pipe 4.3 facing the upper roller ring 2. The short nozzles 4.5 on both sides of the U-shaped cooling water pipe 4.2 are vertically downward and facing the roller surface of the upper roller ring 2. The short nozzles 4.5 in the middle of the U-shaped cooling water pipe 4.2 and on the first vertical water pipe 4.3 are obliquely downward at 45° and aligned with the side wall of the upper roller ring 2. The first water receiving pipe 4.1 is connected to an external cooling water source.

[0023] The lower cooling structure 5 includes a second water inlet pipe 5.1, a trapezoidal cooling water pipe 5.2, two second vertical water pipes 5.3, and several long nozzles 5.4. The second water inlet pipe 5.1 is located on one side of the middle of the trapezoidal cooling water pipe 5.2 and is connected to a cooling water source. The two second vertical water pipes 5.3 are parallel to and symmetrically arranged on the two sides of the trapezoidal cooling water pipe 5.2, opposite to the second water inlet pipe 5.1. The two second vertical water pipes 5.3 are located on the two sides of the lower roller ring 3. On both sides of the sidewall, the ends of the trapezoidal cooling water pipe 5.2 and the second vertical water pipe 5.3 are sealed by the second plug 5.5. The plurality of long nozzles 5.4 are evenly arranged on the upper part of the trapezoidal cooling water pipe 5.2 and the side of the second vertical water pipe 5.3 facing the lower roller ring 3.

[0024] The working process of this utility model:

[0025] When this utility model is in use, the first water inlet pipe 4.1 and the second water inlet pipe 5.1 are connected to a cooling water source. The cooling water enters the U-shaped cooling water pipe 4.2 and the first vertical water pipe 4.3 in sequence along the first water inlet pipe 4.1, and then sprays out from the short nozzles 4.5. The short nozzles 4.5 on both sides of the U-shaped cooling water pipe 4.2 are aimed at the roller surface of the upper roller ring 2 for cooling spraying, and the short nozzles 4.5 in the middle of the U-shaped cooling water pipe 4.2 and on the first vertical water pipe 4.3 are aimed at the side wall of the upper roller ring 2 at an angle downward for cooling spraying.

[0026] Cooling water enters the trapezoidal cooling water pipe 5.2 and the second vertical water pipe 5.3 sequentially along the second water inlet pipe 5.1, and then sprays out from the long nozzle 5.4. The long nozzle 5.4 in the middle of the trapezoidal cooling water pipe 5.2 is aimed at the roller surface of the lower roller ring 3 for cooling spraying, and the long nozzles 5.4 on both sides of the trapezoidal cooling water pipe 5.2 and on the second vertical water pipe 5.3 are angled upwards to be aimed at the two side walls of the lower roller ring 3 for cooling spraying.

[0027] The upper cooling structure 4 and the lower cooling structure 5 work together to cool the upper roller ring 2 and the lower roller ring 3 in all directions, ensuring uniform cooling of all working surfaces of the roll, especially the roll fillet, thus avoiding phenomena such as roll chipping and scaling, and ensuring product quality.
