Embodiment Construction

[0033] The invention provides a method and device for eliminating the spiral roll mark of the strip steel surface pass machine, which mainly solves the problem of the spiral roll mark defect of the strip steel pass finish machine on the continuous hot-dip galvanizing production line through a simple equipment transformation method, and the transformation is without The modification of mechanical and electrical hardware basically does not require capital investment. After the transformation is successful, there is no additional maintenance cost.

[0034] like figure 1 As shown, the device provided by the present invention for eliminating the spiral roll mark of the skin pass mill of the strip steel includes: a high pressure cleaning nozzle 9 , a flat nozzle 10 , a horizontal moving frame 11 of the nozzle and a work roll 12 of the skin pass mill. The high-pressure cleaning nozzle 9 includes an upper high-pressure cleaning nozzle 1 and a lower high-pressure cleaning nozzle 2 . T...

Abstract

The invention discloses a method for eliminating spiral roll marks on a steel strip surface finishing machine. The method comprises the following steps of: initially washing the roll surface of the finishing machine by using spiral water current; and scraping the roll surface of the finishing machine by using fan-shaped water current, and further washing the roll surface. The invention further discloses a device for eliminating spiral roll marks on the steel strip surface finishing machine. Under the condition of slightly modifying high-pressure washing equipment of the finishing machine, thedefect of spiral roll marks on the steel strip surface finishing machine can be eliminated, the roll replacing times of the finishing machine on a continuous zinc-plating production line can be reduced, and the production cost is greatly lowered.

Description

technical field [0001] The invention relates to the technical field of cold-rolled strip rolling, in particular to a method and a device for eliminating spiral roll marks of a strip steel surface pass machine. Background technique [0002] During the continuous hot-dip galvanizing production process of strip steel, some zinc powder and zinc particles are often attached to the roll surface of the skin pass machine on the continuous hot-dip galvanizing production line, which needs to be cleaned by high-pressure cleaning equipment. At present, the existing domestic high-pressure cleaning devices use high-pressure water cleaning to have the following problems: the high-pressure cleaning nozzle generally presents a spiral spray, resulting in the formation of uneven spiral residual zinc powder marks on the surface of the skin-passing machine, and these zinc powder marks are copied to the belt. On the surface of the steel, a skin pass machine spiral roll mark defect will be formed...
