Method for improving use reliability of lubricating system for 5M rolling mill stand roll

Abstract

The invention discloses a method for improving the use reliability of a lubricating system for a 5M rolling mill stand roll. The method for improving the use reliability of the lubricating system for the 5M rolling mill stand roll is characterized in that a pipeline of the lubricating system for the rolling mill stand roll is transformed, the design that one main pipe of the original pipeline is divided into four branch pipes to lubricate four stand roll user points separately, finally, the four branch pipes are gathered to the main pipe and return to an oil tank, and only the main pipe is provided with a pressure monitor is changed into the design that the four stand roll user points are provided with an independent loop for lubrication separately, the loops do not influence one another, each loop is independently provided with a flow meter and a pressure sensor, and real-time monitoring for lubrication pressure and flow of the four stand roll user points is realized. According to the invention, poor lubrication and uneven lubrication of a stand roll bearing are effectively avoided, and the service life of the stand roll is prolonged.

Description

technical field [0001] The invention relates to a rolling mill system of a wide and heavy plate mill, in particular to a lubrication system for rolls of a rolling mill stand. Background technique [0002] The 5M rolling mill in the wide and heavy plate factory is usually a single stand, with a wide variety of rolling products. The thick plate rolling is transported to the entrance and exit of the rolling mill through the steel transfer roller table and the stand roller for rolling. The entrance stand rolls are built in the rolling mill archway at the entrance side of the rolling mill, and the exit stand rolls are built in the rolling mill archway at the rolling mill exit side. They have the same function as the steel-turning roller table but do not turn steel. Due to the lack of space, the rack rollers are all driven by a single motor, and the other two rollers are driven by two motors arranged in front and back through the speed change mechanism. The internal bearings of t...

AI Technical Summary

Problems solved by technology

In May 2020, the 5M rolling mill of a wide and heavy plate factory was uncontrollable and poorly lubricated due to the uncontrollable lubrication point of the rolls of the exit stand, and the bearings of the rolls of the exit stand were burned. The accident caused the rolling line to stop for 26 hours, causing major economic losses
