Roller grinding method

Abstract

The invention belongs to the field of metallurgical machinery maintenance, and discloses a roller grinding method. 80# or 100# is adopted in a grinding wheel of a grinding machine. The transverse moving speed of the Z-axis of the grinding machine is 2000mm / min, the continuous feed rate of the X-axis is 0.015mm / min, the grinding pressure is 1.0-1.5Pa, and the surface roughness of a roller is 0.2-0.7um. According to the roller grinding method, the phenomenon of strip steel deviation can be avoided effectively, the rolling efficiency of strip steel is improved, and the quality of strip steel products is improved.

Description

technical field [0001] The invention belongs to the field of metallurgical machinery maintenance, and in particular relates to a roll grinding method. Background technique [0002] During the rolling process of the 20-high rolling mill, when the rolling speed reaches 200m / min, the deviation of the strip often occurs, resulting in poor shape of the strip. Contents of the invention [0003] In order to increase the roughness of the rolls, avoid the phenomenon of strip steel deviation, and improve the strip steel rolling efficiency, the invention provides a roll grinding method. [0004] Technical scheme of the present invention is: [0005] 1. The grinding wheel of the grinding machine is 80# or 100#; [0006] 2. The Z-axis traverse speed of the grinding machine is 2000mm / min; the X-axis continuous feed rate is 0.015mm / min; [0007] 3. The grinding pressure is 1.0~1.5 Pa, and the surface roughness of the roll is 0.2~0.7 um. [0008] The invention can effectively avoid...
