Embodiment Construction

[0022] The invention aims at the requirement of mass production of checkered plates. By readjusting the profile of the checkered rolls, the checkered rolls have the function of continuously changing the convexity, which strengthens the ability of the rolling mill to control the plate shape, and can accurately and effectively make the gap between the work rolls The curve matches the shape curve of the rolled piece, which increases the range of use of the rolling mill, can obtain a good shape, and creates conditions for the mass production of checkered plates.

[0023] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments.

[0024] like figure 1 As shown, it is a structural schematic diagram of the upper work roll 11 provided with pattern protrusions 12 in the present invention. In this preferred embodiment, the upper work roll 11 is a patterned roll, and the patterned protrusions ...

Abstract

The invention discloses a checkered plate rolling method using continuous convexity-changeable roller-type checkered rollers. The checkered plate rolling method using the continuous convexity-changeable roller-type checkered rollers comprises setting working parameters of the continuous convexity-changeable roller-type checkered rollers on a rolling machine which rolls steel plates according to set multinomial coefficients. The continuous convexity-changeable roller-type checkered rollers comprises an upper working roller and a lower working roller, the upper working roller starts working from an operating side, and the lower working roller starts working from a transmission side. The checkered plate rolling method using the continuous convexity-changeable roller-type checkered rollers solves the difficult problem that the plate shapes of the checkered plates manufactured by the rolling machine can not be stably controlled, and reduces steel pile-up accidents of manufacturing the checkered plates.

Description

technical field [0001] The invention relates to a processing method of a metal plate, in particular to a method for rolling a patterned plate by using a continuously variable convexity roll-type patterned roll. Background technique [0002] The steel plate with patterns on the surface is beautiful, can increase friction, strengthen performance, and save steel, and is widely used in construction, shipbuilding, transportation, and machinery manufacturing industries. The pattern of the lentil-shaped checkered plate is an open shape, and it is the most widely used checkered plate at present. Its advantages are elegant appearance, good anti-skid effect, and no oil and water. There is a large market for checkered plates in Northwest China and North China, so the development of checkered plates has great economic and social benefits. [0003] The target crown setting for the finished product is 40 microns, but the strip crown is less than the target value. The original patterned...
