Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] The present invention is a rolling mill back-up roll hydraulic liner assembly, the structure of which is as follows Figure 1~3 As shown, the liner body 1 is included, and the center of the liner body 1 is provided with two pistons 2, each piston 2 is coaxially sleeved with a compression ring 3, and the four vertices of the liner body 1 are respectively provided with screws 4 , A disc spring 5 is provided between the screw head of the screw 4 and the pressure ring 3 .

[0028] Wherein the liner body 1 is a cuboid structure, the center of the liner body 1 is provided with two circular grooves 6, the two circular grooves 6 are arranged along the length direction of the liner body 1, and the two pistons 2 are correspondingly installed in the two circular grooves within 6.

[0029] Wherein the piston rod of the piston 2 is sleeved with a...

Abstract

The invention discloses a rolling mill supporting roller hydraulic lining plate assembly which comprises a lining plate body. Two pistons are arranged in the center of the lining plate body. The outer portion of each piston is coaxially connected with a press ring in a sleeved manner. Screws are arranged at the four vertexes of the lining plate body correspondingly. A disc spring is arranged between a screw head of each screw and the corresponding press ring. The invention further discloses an application method of the lining plate assembly. The rolling mill supporting roller hydraulic lining plate assembly solves the problem that at present, a rolling mill supporting roller bearing pedestal copper sliding plate is worn seriously, and consequently the precision of a rolling mill is reduced.

Description

technical field [0001] The invention belongs to the technical field of metallurgical equipment, and relates to a hydraulic liner assembly for a back-up roll of a rolling mill, and also relates to a method for using the liner assembly. Background technique [0002] The rolling mill is the main engine of metallurgical equipment, and the roll assembly is the most critical part of the rolling mill. Since the back-up roll device needs to be replaced frequently, and the gap between the liner and the liner on the rolling mill frame should be minimized, the actual situation is that the back-up roll bearing Install copper slide plates on both sides of the seat, and let the fitter grind the copper slide plates before installation. Although in the initial stage of grinding, the gap between the copper slide plate and the rolling mill liner is small, and the precision of the whole rolling mill is relatively good, but after several roll replacements, the copper slide plate will be worn an...
