Abstract

The invention provides an upper supporting roll balancing device for a rolling mill, which comprises a carrying pole beam, a balance hanging board and a guide lifting cylinder, wherein the carrying pole beam is arranged above an upper beam of the rolling mill, the balance hanging board is connected to the carrying pole beam, and the guide lifting cylinder is connected to the balance hanging board. By adopting the upper supporting roll balancing device provided by the invention, the frequency of regulating the guide lifting cylinder can be reduced, and the service life of a hydraulic cylinder is prolonged.

Description

technical field [0001] The invention relates to the field of large-scale steel rolling equipment of metallurgical machinery, in particular to a balancing device for back-up rolls on a rolling mill. Background technique [0002] In order to eliminate the gap between the pressing screw pair, the pressing screw and the spherical thrust pad (or thrust bearing), the spherical thrust pad (or thrust bearing) and the upper back-up roll bearing seat, the upper back-up roll bearing seat and the bearing in the rolling mill And between the bearing and the roll, if the upper AGC (automatic thickness control) is used, it also includes the harmful gap between the AGC cylinder and its upper and lower related parts due to the action of gravity, so as to avoid the impact of biting, rolling and throwing steel, and protect the Equipment, to maintain stable rolling, the upper backup roll balance device is installed on the rolling mill. [0003] At present, in large-scale strip rolling mill equi...
