Abstract

The invention provides a method for installing a rolling mill pressure cylinder in a limited space. The method comprises the following steps that 1, construction information is acquired, and a plurality of special lifting appliances are arranged according to the construction information; 2, the overall strength of all the special lifting appliances is inspected; 3, the special lifting appliances are arranged on a hydraulic cylinder; 4, steel wire ropes and chain blocks are arranged on a traveling crane lifting hook and a roll housing, and the steel wire ropes and the chain blocks are connected to the special lifting appliances correspondingly; and 5, the chain blocks are adjusted, a traveling crane is driven to conduct hoisting, and balance of the pressure cylinder is controlled in real time till the pressure cylinder is installed in place. The special lifting appliances are arranged on the pressure cylinder and connected to the traveling crane through the chain blocks and the steel wire ropes for lifting, the pressure cylinder can be balanced by adjusting the chain blocks, and then it is guaranteed that the pressure cylinder can be safely and stably installed in place.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment installation, and in particular relates to an installation method of a pressing upper cylinder of a rolling mill in a limited space. Background technique [0002] Rolling mill upper cylinder is the core device of the rolling mill. Whether its performance is good or not determines the quality of the strip. The hydraulic pressure upper cylinder is one of the outstanding and important symbols of the modernization of the rolling mill. It is easier to adapt to changes in rolling and operating conditions. According to The rolling type and rolling pass program, such as press rolling or temper rolling, can give the best compensation, and use the feature of adjustable rigidity of the rolling mill, and adopt a descending rigidity distribution method for the cold rolling mill to obtain high High-quality products, so as to ensure strip thickness and flatness, so that the strip quality is the best...
