Embodiment 1

[0026] The present embodiment provides a kind of technological method of grinding roll, as figure 1 As shown, the method includes:

[0027] S101, use a 120# ceramic grinding wheel to perform rough grinding and semi-rough grinding on the roll, during the rough grinding process, control the linear speed of the grinding wheel to 37-38m / s, control the speed of the roll to 39-40rpm, and control the Z-axis longitudinal direction of the grinder The moving speed is 2800~3000m / s.

[0028] In this step, before the rough grinding of the roll, the support roll is used to support the roll to place the roll on the grinder, and after the roll is placed on the grinder, the 120# ceramic grinding wheel is used to carry out rough grinding and semi-rough grinding of the roll, In order to be able to grind away the removal amount of the roll to ensure that the fatigue layer of the roll is removed. The hardness level of the 120# vitrified grinding wheel is L level. It should be noted that through...

Abstract

The invention provides a process for grinding rolls, comprising: using a 120# ceramic grinding wheel to perform rough grinding and semi-rough grinding on the rolls, during the rough grinding process, the linear velocity of the grinding wheel is controlled to be 37-38m / s, and the rotational speed of the rolls is controlled to be 39~40rpm, control the Z-axis longitudinal movement speed of the grinding machine to 2800~3000m / s; in the semi-coarse grinding process, control the grinding wheel linear speed to 35~36m / s, control the roll speed to 37~38rpm, control the Z-axis longitudinal movement speed of the grinding machine 2600~2800m / s; 320# ceramic grinding wheel is used for semi-fine grinding of the roll. During the semi-fine grinding process, the linear speed of the grinding wheel is controlled to be 22-24m / s, the speed of the roll is controlled to be 34-38rpm, and the Z-axis longitudinal direction of the grinder is controlled. The moving speed is 600-800m / s; use 320# ceramic grinding wheel to fine-grind the roller. During the fine-grinding process, control the linear speed of the grinding wheel to 18-22m / s, control the speed of the roller to 42-54rpm, and control the Z-axis longitudinal direction of the grinding machine. The moving speed is 400-500m / s; among them, the semi-fine grinding includes: the first semi-fine grinding and the second semi-fine grinding; the fine grinding includes: the first fine grinding, the second fine grinding and the third fine grinding Grinding; the concentration of grinding fluid is 3.5-4.0%.

Description

technical field [0001] The invention belongs to the technical field of iron and steel smelting, and in particular relates to a process for grinding rolls. Background technique [0002] As a kind of strip steel with huge market demand, high-gloss mirror panel has been widely used in food and catering, LED lights, locks, gift packaging, lighters and other fields. [0003] The feature of high-gloss mirror panels is that they have extremely high requirements on the surface quality of the product. The surface roughness must be controlled below Ra0.3μm, and there must be no defects such as chromatic aberration, scratches, and roll marks. Currently, the high-gloss mirror panels produced in China Quality cannot be guaranteed, and high-gloss mirror panels are mainly dependent on imports, which leads to higher production costs. Contents of the invention [0004] Aiming at the problems existing in the prior art, the embodiment of the present invention provides a process method for g...
