Machining device for improving roller surface clearness and machining method thereof

Abstract

The invention discloses a machining device for improving the roller surface clearness and a machining method thereof. The machining device is connected to a machine body of a grinding machine, and comprises a shell body, a compression mechanism, a hydraulic mechanism and a surface treatment mechanism; the hydraulic mechanism is arranged above the shell body, the shell body is connected to the machine body of the grinding machine through the hydraulic mechanism, and one end of the surface treatment mechanism is connected to one side edge of the shell body through the compression mechanism and is arranged below the shell body; and the surface treatment mechanism comprises a steel plate and abrasive paper, the upper surface of the steel plate is in contact with the shell body, the abrasive paper is connected to the lower surface of the steel plate, the abrasive paper and the steel plate form a whole, and the lower surface of the abrasive paper is used for machining the roller surface clearness. By means of the machining device and the machining method, generation of powder in the roller rolling process can be reduced, strip steel surface spot defect generation caused by reduction of the roller surface clearness is reduced, meanwhile, the roller roughness attenuation is reduced, and the roller abrasive resistance is improved.

Description

technical field [0001] The invention relates to roll surface processing technology, more specifically, relates to a processing device and a processing method for improving the cleanliness of the roll surface. Background technique [0002] With the increase of market demand, customers have relatively higher requirements on the surface quality of the strip and the color difference of the strip surface, and the surface quality of the roll is directly reflected on the surface of the strip, so the quality of the strip surface and the quality of the roll Surface quality is closely related. [0003] According to the on-site tracking research, first, in terms of cleanliness, the surface of the roll has an impact on the cleanliness of the strip. After the new roll is put on the machine, the surface cleanliness of the strip is between 80-85 within 0-500 tons; The surface cleanliness of the strip is between 65-60 at 500-1000 tons; the surface cleanliness of the strip is between 55-60 ...

AI Technical Summary

Problems solved by technology

If the surface cleanliness of the strip is lower than 60, the cleaning pressure on the unit in the next process will increase, and it is very likely that the surface of the strip will be stained, which will affect the qualified rate of the product.

It can be seen from the above data that there will be a risk of bad rolls when the roll is 2000-3000 tons, so only new rolls can be replaced, thus reducing the rolling kilometers of each roll and increasing the roll change of the rolling mill per unit time time, thereby reducing the output
