Description

Apparatus for adsorbed grit removing of shot blasting roll surface}

The present invention relates to an apparatus for removing grit adsorbed or adhered to a roll surface during shot blasting to give roughness (roughness) to the roll surface.

In general, by lowering the yield elongation of the cold rolled strip, giving a predetermined shape, hardness and roughness, and spraying a certain amount of grit at a high pressure and high speed on a skin pass roll to improve paintability. To give the rolls the appropriate roughness, this is referred to as shot blasting or less processing. As such, after the shot blasting process, the grit and the adhered foreign matter adsorbed or fixed on the roll surface should be removed.

Conventionally, as shown in FIG. 1, when the roll 200 processed in the shot blast processing equipment exits the equipment and rotates on the trolley 300, the operator 100 visually looks at the shot blast processing roll 200 surface. Look and remove the air gun 400 by spraying it toward the grit or foreign matter adsorbed on the surface of the roll. Removal of the grit may lead to secondary defects on the processing rolls, and also, if the adhered grit remains on the roll surface, there is a problem of causing defects by being transferred to the strip during rolling in a later process.

The present invention has been made to solve the above problems, the surface of the shot blasting roll that can more efficiently and easily remove the adsorbed or stuck grit during the shot blasting process to give roughness to the roll surface It is an object of the present invention to provide a grit removing device adsorbed on the substrate.
