Rolling Oil
Cold rolling oil is used to enhance the surface quality through lubrication and cooling frictional heat and plastic deformation heat generating during the cold rolling process.
Classifications of Cold Rolling Oil
| · By dilution (water-soluble and neat) | · By rolling mill types (TCM, RCM, Z-Mill, SPM) |
| · By up and down process (MC, CAL, BAF, CGL) | · By thickness (high-speed thin plate, and sheet) |
| · By ingredients of rolling oil (oil base, synthetic ester, and mineral base) | · By materials (steel, stainless steel, electrical steel sheet, and non-ferrous metals such as aluminum) |
| Classification | Circulation Type | Composition | Rolling Mills | Applications |
|---|---|---|---|---|
| Neat | Circulation type | Mineral based | Reverse Mill | General steel, high alloy steel sheet stainless steel, high carbon steel |
| Water-soluble | Direct type | Oil and fat based | PCM | Galvanized steel sheet, special steel, BP, high tensile steel |
| Circulation Type | Mineral based | Reverse Mill | General steel, stainles steel, electrical steel sheet, high carbon steel | |
| Oil and fat based, mixed, and ester based | Reverse Mill, PCM | General thin steel sheet, automotive steel sheet, BP, high carbon steel, electrical steel sheet |
