Description

Strip steel surface cleaning device before rolling Technical Field The invention relates to the technical field of rolling mill equipment, in particular to a device for cleaning the surface of strip steel before rolling. Background The rolling mill is also called a roller mill, and can crush and homogenize viscous substances, and when the strip steel is produced and prepared, the strip steel is rolled by a six-roller five-connection unit, so that the strip steel is subjected to uniform-texture shaping deformation. The six-roller five-tandem rolling unit adopts a pressure processing mode, and during processing, a rolled piece is subjected to plastic deformation through large rolling force, and the surface quality of strip steel in the rolling process mainly depends on whether the surface of the strip steel contacted with the roll surface is clean or not and the cleanliness of an emulsion system. However, in the production process of a five-continuous rolling unit in an acid rolling workshop of a sand steel cold rolling mill, the defect of hard rolling foreign matter pressing in is overcome because the outermost roller of the three-roller stabilizing roller surface at the inlet of the rolling mill is free from emulsion to wash the sticky foreign matter on the roller surface, the rest roller surfaces washed by the emulsion are clean and no foreign matter is found, and once the sticky foreign matter on the roller surfaces is not cleaned in time, the foreign matter pressing in is caused along with the rolling of strip steel entering the rolling mill, so that the product is judged.
