Lubrication Reliability

 Why is keeping a check on Lubricant so important in Rolling Mills?

Hot Strip Mill, Cold Rolling Mill, Primary Boom Bar Mill, Bar, and Wire Rod Mill and Merchant Mill are parts of the rolling and finishing group.

The equipment is subjected to high impact loads, water and scale ingress, high temperature near reheating furnaces, and higher speed and unit loads in the rolling and finishing group.

This has a negative impact on Lubricant and makes them unfit for the equipment. Keeping a regular check on Oil's condition and Purifying it when necessary becomes really important to avoid mechanical breakdown and to control maintenance cost.

Minimac System has been promoting Lubrication Reliability practices which have helped Steel plants across India to overcome untimely breakdowns and save a large amount spent on maintenance.

A Steam turbine blower was to be commissioned in one of the topmost steel plants in Odisha, India by a leading EPC company, the pipelines were erected on the site and as per the Standard Operating Procedure listed by the Steel Plant Owner Company, the flushing was completed with a single auxiliary pump at 1500 LPM. However, during the trial run of the turbine, the inline lube oil filters would clog very frequently and lead to halted operations.

Problem Statement: Frequent clogging of inline lube oil filters were hindering the operations and delaying the steam turbine commissioning project.

Underlying Issues: On inspection, a root cause analysis was done and the required rate for effective flushing was calculated as 3500 LPM. The Particle contamination level...Read more
