Example Embodiment

[0093] Example

[0094] Such as figure 1 As shown, the figure only takes 2 pairs of brush rollers as an example, but the present invention is not limited to figure 1 2 pairs of brush rollers shown.

[0095] When descaling starts, according to the thickness of the strip, the brush roller moves up and down, the motor drives the brush roller to move the gearbox up and down, and the pair of brush rollers are opened up and down through the movable screw to open the roll gap; the strip is conveyed to the pinch roller through the strip entrance The exit pinch roller makes the strip tight in the device. Start the high-speed nozzle and start the discharge fan. The brush roller moves the motor up and down to adjust the gap between the brush roller pairs, so that the flexible abrasive belt brush strip of the brush roller contacts the surface of the strip.

[0096] Start the drive motors of the brush rollers to the respective brush rollers to remove the oxide scale on the surface of the strip....

Abstract

A plate strip surface scale removal device is used for removing scales on the surface of a plate strip and comprises a removing device used for removing the scales, a gathering device used for gathering the scales, and a dust removing device. According to a scale removal method, through the cooperative work of the removing device, the gathering device and the dust removing device, continuous scale removal work of removing, gathering and dust removing is conducted. According to the plate strip surface scale removal device and method, a continuous dry type flexible brush roll scale removal device and method for plate strip surface scale removal are provided. A plate strip continuously passes through the part between brush rolls arranged up and down, and the scales on the surface of the plate strip are removed through the brush rolls rotating at a high speed. Each brush roll is composed of a spirally-arranged strip-shaped abrasive belt. The strip-shaped abrasive belts rotating at a high speed collide with the surface of the plate strip, sand grains on the abrasive belts grind the scales on the surface of the plate strip away, the scales become fine powder dust and are removed through the gathering device and the dust removing device, and the plate strip surface scale removal work is finished.

Description

technical field [0001] The invention belongs to the field of heat treatment production in rolling, and in particular relates to a strip surface descaling device and a method thereof. Background technique [0002] In the process of rolling and heat treatment, the surface of the strip will inevitably produce a certain thickness of oxide scale, that is, iron scale. For carbon steel strips, the scale is mainly composed of Fe2O3, Fe3O4 and FeO, with a thickness of 7-15 μm, and the surface scale is usually removed by pickling (hydrochloric acid). For stainless steel and special steel plates, in addition to iron oxide, there are oxides such as NiO, Cr2O3, etc. These oxides are very dense and are very firmly combined with the steel plate body. Usually, most of the scale is removed by shot blasting, and then the Pickling with strong acid (hydrofluoric acid, nitric acid + sulfuric acid). The pickling process is inefficient, takes up a lot of space, and causes great damage to the env...
