Rolling mill is used as a processing device for thinning plate materials in industrial sites such as steel mill cold rolling mills.

In the rolling mill apparatus, an oil in water emulsion is used as a lubricant for the purpose of reducing frictional force generated on the friction surface or dispersing frictional heat.

The oil-in-water type emulsion has a volume ratio of about 3% of oil, and most of the remaining water is composed of water, and contains a small amount of factory dust such as coal powder, iron powder, etc., Which greatly influences the performance of the apparatus and the quality of the plate produced by the rolling mill apparatus.
