High-pressure spraying and cleaning device for cold-rolled strip steel

Abstract

The invention relates to the field of cleaning device spraying fluids on the surface of cold-rolled strip steel, in particular to a high-pressure spraying and cleaning device for cold-rolled strip steel. The high-pressure spraying and cleaning device comprises a spraying system (1), a spraying circulating system (2) and an outlet spraying circulating system (3) and is characterized by further comprising a front brushing roll (51), a front support roll (52), a front brushing roll holder (53), a front worm gear lifting machine (54), a rear brushing roll (61), a rear support roll (62), a rear brushing roll holder (63), a rear worm gear lifting machine (64), an upper brushing roll spraying pipe (71) and a lower brushing roll spraying pipe (72). The high-pressure spraying and cleaning device is good in cleaning effect, highly adaptive, and high in economic benefit.

Description

technical field [0001] The invention relates to the field of cleaning devices for spraying fluid on the surface of cold-rolled steel strips, in particular to a high-pressure spraying and brushing device for cold-rolled steel strips. Background technique [0002] Impurities such as rolling oil, iron powder and carbon powder are attached to the surface of the strip after cold rolling, which affects the surface reflectivity of the strip, and causes quality defects such as bell furnace adhesion and poor galvanizing process coating, reducing the The surface quality of the strip steel, so the cleaning process of the strip steel after cold rolling is an important link to improve the quality of the strip steel. At present, the cleaning section of the strip is mainly composed of three parts: the pre-cleaning area, the annealing furnace and the post-cleaning area. The pre-cleaning area is mainly used to clean the rolling oil and a small amount of residual iron powder on the surface of...

Problems solved by technology

A large amount of "silicon mud" adheres to the surface of the silicon steel sheet, and the two sets of equipment in front of the furnace, such as water scrubbing and hot water spraying in the pre-cleaning area, cannot effectively remove the "silicon mud", resulting in the "silicon mud" being accompanied by the silicon steel plate. The belt enters the annealing furnace, causing scarring of the roller table in the furnace, which in turn causes batch roll marks on the silicon steel sheet, affecting product quality
