Abstract
The invention belongs to the field of mechanical equipment, and relates to an acid-free scale removal device for cold rolling. A special scale removal system is designed by aiming at surface treatment of a steel plate before cold rolling, and by adopting the system, mixed slurry of an abrasive and water is accelerated in a pipeline with the help of centrifugal force action and beats the surface of the steel plate at a high speed after passing through a pipeline outlet operating nozzle to remove an oxidized layer. Therefore, the scale removal quality can be controlled by adjusting parameters of the rotating speed of a centrifugal system, the slurry concentration, the nozzle angle, the target distance and the like. In a common acid cleaning process, acid liquor does not react with nonmetal oxides on the surface of the steel plate, so that the nonmetal oxides cannot be removed, and pollution is serious. By adopting the acid-free scale removal device provided by the invention, a mixed abrasive is adopted to perform physical impact on the oxide layer on the surface of the steel plate to ensure that the oxide layer and other impurities on the surface of strip steel can be effectively removed, and the abrasive and water can be recycled, so that the acid-free scale removal device is green and environment-friendly, and the discharge of waste and harmful substances is zero.
