Problems solved by technology

[0005] The purpose of the present invention is to solve the problem of maintaining the shape of the bus bar of the work rolls, and the manufacturing accuracy of the rolling mill must be greatly improved in view of the above-mentioned existing rolling mills that produce rolling indentations on the surface of the rolled parts, which destroy the surface quality of the product. In view of the present situation of production difficulty and cost, a multi-roll rolling mill for eliminating plate and strip rolling marks is provided. In this rolling mill, the backing rolls are staggered and arranged side by side, and the upper and lower roll seats are decomposed and set, so that it can effectively eliminate The rolling marks on the surface of the rolled parts greatly improve the precision of the rolling mill

Embodiment Construction

[0018] figure 1 Shown is a three-dimensional schematic diagram of the first specific embodiment of the present invention, which includes a frame 1 and a symmetrical upper tower roller system that is respectively arranged on the upper and lower sides of the rolled piece 101 in the frame 1 And lower tower-shaped roller system, frame 1 is a tunnel-shaped frame integral body along the tower-shaped roller system axial direction formed by panel 11, back plate 12, top plate 13 and base plate 14 enclosing. The surface of the back plate is provided with a feed opening 121 for the strip blank 102 to enter. The surface of the panel 11 is provided with a discharge port 111 for outputting the rolled piece 101 . Top-to-bottom grooves 7 are respectively opened on the outer surfaces of the panel and the backboard. The opening of the grooves 7 can not only greatly save the manufacturing material cost of the frame 1, but also help to improve the rigidity of the frame in the horizontal directio...

Abstract

A multi-roller rolling mill for eliminating the rolled tracing on plate or band material is composed of a machine frame and upper and lower tower-shaped roller trains. Said machine frame consists of front panel with discharge opening, back plate with feeding opening, top plate and bottom plate. The backing rollers, upper roller seat and lower roller seat are vertically arranged. A pressing down unit is arranged between said top plate and upper roller seat. A regulator is arranged between said bottom plate and lower roller seat. Said backing rollers are staggered.

Description

technical field [0001] The invention relates to a multi-roll rolling mill for eliminating rolling marks on plates and strips, in particular to a multi-roll mill that can eliminate rolling marks on the surface of rolled plates and strips by setting the roll rings of two adjacent backing rolls alternately and side by side. rolling mill. Background technique [0002] In the existing multi-roll mill, most of the backing rolls are segmented rolls composed of a plurality of rings arranged at intervals, and the backing roll is usually supported by a cylindrical body as a whole. roll or work roll. Due to the action of the huge rolling force, the roll ring of the backing roll is squeezed on the surface of the backup roll or the work roll, so that indentations appear on the surface of the backup roll or the work roll and the surface stress is concentrated, thereby causing damage to the surface of the rolled piece Rolling indentation destroys the surface quality of the product or red...
