Problems solved by technology

[0002] At present, in the multi-line cutting process, the roll cooling water pipes are mostly welded by employees using steel pipes. The actual use effect after processing is unstable. The curvature of the cooling water pipes is inconsistent with that of the rolls, resulting in poor cooling effect on the rolls. , the result is that in the production process, due to the poor cooling effect of the rolls, the rolls are often worn and worn out, and the rolling volume is not reached and the rolls are off the assembly line ahead of time, which restricts the normal operation of the production

Embodiment 1

[0018] Embodiment 1: A method for manufacturing roll cooling water pipes in multi-line split rolling, comprising the following steps:

[0019] a. Make cooling water pipe bending standard sample 1: According to the diameter and length of the roll in multi-line slit rolling, make a cooling water pipe bending standard sample 1 with the same curvature as the roll. The structure of cooling water pipe bending standard sample 1 is a cylindrical structure , the outer wall of the cylindrical structure is provided with an annular groove 2, the inner diameter of the annular groove 2 is the same as the diameter of the roll;

[0020] b. Make a single cooling water pipe: heat the processed single cooling water pipe, and then bend it along the cooling water pipe standard sample 1, so that the bending degree of the cooling water pipe is consistent with the roll;

[0021] c, make a plurality of cooling water pipes: repeat step b, make the same cooling water pipes as the number of rolls;

Abstract

The invention relates to the technical field of manufacturing cooling water pipes, in particular to a method for manufacturing roll cooling water pipes in multi-line slitting and rolling. The cooling water pipe can make the bending degree of the cooling water pipe consistent with the roll, and can fully fit the surface of the roll for sufficient cooling. The cooling water pipe is aligned with the standard sample to make a cooling water pipe suitable for the roll in multi-line split rolling, ensuring The distance between the cooling water pipes is the same as the distance between the rolling grooves, so that each roll can be fully cooled, making the online service life of the rolls more stable. Negative difference and line difference are easier to control.
