Method for processing faults of roll bending system of rolling mill on line

Abstract

The invention discloses a method for processing faults of a roll bending system of a rolling mill on line. The method specifically comprises the following steps of (1) measuring and calculating the elevation of each part in the roll bending system of the rolling mill, and dismantling accessory equipment; (2) completing hoisting of the hidden part through a maintenance tool; and (3) carrying out information collection by adopting ODG tracking and on-site temperature measurement, and comprehensively judging a fault point. According to the method, disassembly, assembly and positioning of large equipment can be avoided, stable operation of a rolling mill system is well guaranteed, the maintenance time is saved, and the yield is increased.

Description

technical field [0001] The invention relates to a method for on-line processing of faults, in particular to a method for on-line processing of faults in the roll bending system of a rolling mill. Background technique [0002] The roll bending system of the four-high rolling mill, also known as the work roll balance system, is used to balance the self-weight of the work rolls, and at the same time apply a bending force to the work rolls to control the shape of the roll gap, so as to eliminate the influence of the rolling force on the shape of the steel plate and adjust the shape of the steel plate. , the purpose of flatness, the bending system is the core component of the four-high rolling mill, the bending system of each rolling mill includes 4 bending blocks, which are respectively installed on the rolling mill archway, a total of 16 hydraulic cylinders, such as hydraulic cylinders appear Problems such as channeling pressure, leakage, etc., the bending force cannot reach th...
