Lubricant in rolling mills reduces friction between metal surfaces, prevents wear and tear, and improves efficiency.
Lubricant reduces friction between metal surfaces in rolling mills
Prevents wear and tear on machinery
Improves efficiency by reducing energy consumption
Helps in cooling the metal during the rolling process
Examples: oil-based lubricants, grease, graphite-based lubricants
The major causes of roll breakage in maintenance engineering include material defects, improper setup, excessive tension, and foreign objects.
Material defects such as weak spots or impurities can weaken the roll and lead to breakage.
Improper setup or alignment of the roll can cause uneven stress distribution and eventual breakage.
Excessive tension on the roll can exceed its load-bearing capacity and cause it to break.

The main causes of rolling mill bearing breakage are lack of lubrication, contamination, overloading, and misalignment.
Lack of lubrication can lead to increased friction and heat generation, causing the bearing to fail prematurely.
Contamination from dirt, debris, or water can accelerate wear and tear on the bearing surfaces.
Overloading the bearing beyond its capacity can cause excessive stress and lead to failure.
Misal...
Compressor overhead cause can be due to various factors such as high discharge pressure, low suction pressure, dirty filters, or worn out components.
High discharge pressure can lead to overheating of the compressor.
Low suction pressure can cause the compressor to work harder and overheat.
Dirty filters can restrict airflow and cause the compressor to overheat.
Worn out components such as valves or seals can lead to ineff
Wire rope condition can be measured by visual inspection, non-destructive testing, and load testing.
Visual inspection for signs of wear, corrosion, broken wires, and distortion
Non-destructive testing methods like magnetic particle inspection, ultrasonic testing, and dye penetrant testing
Load testing to assess the strength and integrity of the wire rope under working conditions
