Device and method for removing oxide scales from hot rolled steel bands by using steel wire roller brush

Abstract

The invention discloses a device and a method for removing oxide scales from hot rolled steel bands by using a steel wire roller brush. The device comprises at least one center shaft along the width direction of a steel band; each center shaft is provided with a steel wire roller brush; the length of each steel wire roller brush is greater than the width of the steel band; the brush diameters of all positions of each steel wire roller brush along the width direction of the steel band are set according to bending degrees of friction surface sections, corresponding to the positions, of the steel band. As the brush diameters of all positions of each steel wire roller brush along the width direction of the steel band are set according to the bending degrees of the friction surface sections, corresponding to the positions, of the steel band, so each steel wire roller brush rubs the whole width of the steel band during work, each position of the steel band can be rubbed with each steel wire roller brush, phenomena of excessive friction at one position and no friction at the other position are avoided, and compared with a structure that the whole steel wire roller brush cannot be in contact with all positions of the steel band in the prior art, the device has the advantages that the oxide scales attached to all positions of the steel band can be removed, and the oxide scale removing effect is greatly improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing and manufacturing, in particular to a device and a method for removing iron oxide scale of a hot-rolled steel strip by using a steel wire roller brush. Background technique [0002] The modern more advanced continuous pickling method for removing scale from hot-rolled steel strips usually includes the following steps: firstly, stretching and bending are used to continuously break the scale with mechanical devices, and the difference in ductility of the material between the scale and the steel strip matrix is ​​utilized. , can loosen the iron scale and most of it will fall off from the hot-rolled steel strip substrate. This step is called scale breaking treatment; then the pickling process is carried out to remove the remaining iron scale, and then it is washed with water, dried, and passivated. [0003] The above pickling method can well remove scale and meet the quality requirements...

AI Technical Summary

Problems solved by technology

However, the problem with the pickling method is that it causes great pollution to the society

When the wider steel strip 100″ needs to be rubbed, the groove part cannot touch the steel strip 100′, so the entire wire roller brush needs to be replaced, resulting in a smaller range of use of the above-mentioned wire roller brush and a higher cost of use of the entire device
