A roll cleaning device for a cold rolling mill

Abstract

The invention discloses a roller cleaning device for a cold rolling unit. Two oil baffle plates are provided; two oblique oil scraping plates are provided; the oil baffle plates are connected with the oblique oil scraping plates; two fixing blocks are arranged on an operation side supporting roller shaft seat and a transmission side supporting roller bearing seat respectively; the fixing blocks are provided with oblique sliding chutes and vertical sliding chutes; the oblique oil scraping plates are arranged in the oblique sliding chutes, and can slide up and down along the oblique grooves; a roller cleaning frame is arranged in the vertical sliding chutes, and can slide up and down along the vertical grooves; vertical oil scraping plates are fixed together with the roller cleaning frame after being flattened by a pressure plate, and are arranged on the roller cleaning frame through adjusting buttons; a disc spring is connected with guide pins; the guide pins are inserted into through holes in the two ends of the roller cleaning frame; fastening screws are arranged on the fixing blocks. The roller cleaning device for the cold rolling unit has high roller cleaning efficiency, is convenient to disassemble and assemble, and is easy to adjust; a roller cleaning strip always sticks close to a roller surface along with the roller diameter change of a support roller.

Description

technical field [0001] The invention relates to the field of back-up roll surface cleaning and strip degreasing of a cold-rolling unit, in particular to a roll-cleaning device for a cold-rolling unit. Background technique [0002] When the cold rolling unit is rolling, when the strip passes through the rolls at a high speed and a single pass with a large reduction rate, debris may be generated. The debris adheres to the work rolls and will be transferred to the work rolls as the rolls rotate. contact with the backup roller. If the debris is not removed, it will affect the roll and strip surface. In the modern cold rolling process, in order to lubricate the surface of the roll and reduce the temperature of the roll, the rolling fluid is sprayed on the entrance side of the roll, and the rolling fluid sprayed on the back-up roll will be transferred to the exit side of the rolling mill with the rotation of the back-up roll, and finally falls On the strip, the difficulty of deg...

If the debris is not removed, it will affect the surface of the roll and strip

In the modern cold rolling process, in order to lubricate the surface of the roll and reduce the temperature of the roll, the rolling fluid is sprayed on the entrance side of the roll, and the rolling fluid sprayed on the back-up roll will be transferred to the exit side of the rolling mill with the rotation of the back-up roll, and finally falls On the strip, it greatly increases the difficulty of degreasing the strip
