Problems solved by technology

The basic principle is that in the saddle between the backing bearings of support rollers B and C, an outer eccentric ring is installed outside the inner eccentric ring of the pressing device, and the eccentric ring is respectively driven by an adjusting hydraulic cylinder or a hydraulic motor The rotation of the eccentric ring, the rotation of any one of the outer eccentric rings can cause the corresponding deformation of the shaft of the support roll group, so as to eliminate the partial or entire thickness unevenness of the rolled strip. This control device can only control two parts B and C. The support roller is used to control the plate shape, the actual control effect is not good, and the adjustment is not strong

Embodiment Construction

[0046] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0047] Such as figure 1 As shown, the novel 20-roll rolling mill of the present invention comprises frame 4, roll system, roll box, pressing device, drive unit, is characterized in that:

[0048] 1) The frame 4 is an overall frame archway with a rectangular shape cast from high-quality steel, and the window of the archway is rectangular. The roller box 2 and the lower roller box 1 symmetrical to the upper roller box 2 are composed, and the sliding mating surfaces of the archway window and the upper and lower roller boxes are planes,

[0049] Such as figure 1 , figure 2 As shown, there are 8 groups of rectangular saddles 10 installed in the roll box of a 20-roll rolling mill, and 4 sets of rectangular saddles are respectively installed in the upper and lower roll boxes, which are symmetrically arranged up and down and left and right. Th...

Abstract

A novel 20-roller rolling mill is composed of integral rectangular machine frame, a roller box unit consisting of upper and lower roller boxes with rectangular saddle and lock unit, a dual-wedge regulator for said lower roller box and comprising swinging cylinder, swinging arm, connecting rod and wedge blocks, and the convexity controller consisting of hydraulic cylinder, rack bar and sectorial gear.

Description

technical field [0001] The invention relates to the field of rolling equipment, in particular to a novel 20-roll rolling mill. Background technique [0002] The 20-high mill is used to produce thin cold-rolled strip. The difficulty in the design of the 20-roll mill lies in the structure of the roll box. The cooperation between the roll box and the archway and the structure of the archway have a great influence on the performance of the rolling mill. Conventional roll boxes are very difficult to process, and the machining accuracy cannot be guaranteed, which affects the matching accuracy between the roll box and the arch window. It is also difficult for the conventional roll box to adapt to the actual situation that the roll system has a large roll diameter difference. Therefore, there should be a More rational design of rolling mill stand and roll box. [0003] In a traditional 20-roll rolling mill, the roll necks of the outer support rolls are supported on backing bearing...
