Novel metal plate strip surface cleaning method and device

Abstract

A novel metal plate surface strip cleaning method and device is characterized by comprising an upper pressure box and a lower pressure box (41 and 42) which are oppositely disposed on the upper surface and the lower surface of a metal plate strip, the upper and lower pressure boxes (41 and 42) are soaked in grinding mud blended with multi-edged fine particulate matter to be in pressure contact with a metal plate surface, and a pressure contact surface of the upper and lower pressure boxes (41 and 42) and the metal plate surface a soft and wear-resisting surface. The novel metal plate strip surface cleaning method and device mainly used for surface cleaning of a cold metal plate strip surface is of a purely physical way and not involved in pollution of chemistry, dust, noise, and the like, and has good capacity of environmental improvement. By the method and device, the capacity of energy conservation and emission reduction of a metallurgy industry can be improved, surface quality of the cold / hot rolled metal plate strip can be improved the same time, and the quality defect of the rolled metal plate surface can be overcome. The novel metal plate surface strip cleaning method and device has broad application prospects in the field of cold rolling production.

Description

technical field [0001] The present invention relates to the technical field of metal surface cleaning. Specifically, the present invention relates to a novel method and device for cleaning the surface of metal strips. The grinding surface with a certain pressure is in pressure contact with the upper and lower surfaces of the metal strip. Through the joint action of the grinding mud and the pressure surface, it is ensured that the metal strip can realize the removal of surface attachments after passing through the grinding surface that is in pressure contact with the upper and lower surfaces of the metal strip. , to ensure that the surface of the metal is kept clean enough when it enters the next process flow, effectively improving the surface quality of the finished metal and the efficiency of post-processing. Background technique [0002] During the hot rolling or heat treatment process of steel, alloy and other metal materials, a layer of dense covering composed of metal o...

Problems solved by technology

For example, 3M Company has designed a brush roller with bristles, and each bristle surface is adhered with multiple hard particles, such as SiC particles, brown corundum, etc., which are used to achieve the cleaning effect when the brush roller and the surface of the metal strip are rolled and scrubbed. However, the hard particles adhered to the surface of the bristles are easy to fall off, which directly affects the stability of the use effect of the brush roller

China's Anhui Qianshan Brush Roller Factory processes a variety of hard brush rollers for brushing off the scales on the surface of metal strips. The bristles are usually made of wear-resistant rigid materials. Brushing, the roughness of the board surface after brushing is large, and the uniformity of cleaning is difficult to be guaranteed
