Description

Technical Field

[0001] The utility model relates to the field of descaling of profiled steel, in particular to a descaling device for profiled steel rolling. Background Art

[0002] Steel is oxidized at high temperature, forming a dense layer of scale on its surface. If this layer of scale cannot be removed before rolling, it will be pressed into the surface of the strip by the rolling mill during the rolling process, affecting the surface quality of the strip. The remaining scale will also accelerate the wear of the rolling mill rolls and reduce the service life of the rolls; and the descaling device for profiled steel rolling is a device used to remove the scale on the surface of profiled steel.

[0003] At present, the Chinese patent with the publication number CN211191431U discloses a high-pressure water oblique cutting descaling device, which includes a rolling line outlet frame. Two rolling rolls are rotatably installed on the rolling line outlet frame. The front surface of the rolling line outlet frame is provided with an upper fixed pipe and a lower fixed pipe. The left ends of the upper fixed pipe and the lower fixed pipe are respectively communicated with the two ends of a three-way pipe. The other end of the three-way pipe is communicated with one end of a water delivery pipe. The other end of the water delivery pipe is communicated with an external water tank through the water outlet pipe of an external high-pressure water pump. The lower surface of the upper fixed pipe and the upper surface of the lower fixed pipe are respectively fixedly installed with an upper A spray pipe, an upper B spray pipe, a lower A spray pipe and a lower B spray pipe. The bottom ends of the upper A spray pipe and the upper B spray pipe and the top ends of the lower A spray pipe and the lower B spray pipe are respectively threadedly installed with upper A spray heads, upper B spray heads, lower A spray heads and lower B spray heads. A collection tank is welded to the lower surface of the rolling line outlet frame. The patent points out the defects of the prior art: the scale on the surface of profiled steel has strong adhesion and is not easy to fall off completely. After re-rolling, it will cause serious defects on the surface of profiled steel, bringing irreparable consequences, and the profiled steel will be directly scrapped; although this device solves the above deficiencies, it also has the following new defects: 1. This device cannot clamp and fix the profiled steel to rotate it for multi-angle high-pressure flushing descaling, and the descaling is incomplete; 2. This device is not convenient for transportation and cannot be used in multi-scene work. Summary of the Invention
