Copper Cold Rolling oil is divided into 4 categories: Mineral Oil, animal and vegetable oil, mixed oil, blend oil

1. Mineral Oil

Mineral Oil is the most widely used lubricating oil in copper pressure processing. It is a non-polar substance and can only form a non-polar physical adsorption film on the surface of copper products, it is usually used as a base oil for the formulation of process lubricants.

2. Animal and vegetable oils

Oil Or fat, extracted from animal or plant seeds, is a polar substance, which not only easily forms a physical adsorption film on the surface of copper products, but also forms a chemical adsorption film on the lubricating surface of polar molecules, it's a good lubricant. But the chemical stability of animal and vegetable oil is poor, easy to aging and deterioration, and the price is higher, in the actual production less direct use.

3. Blend oil

Mixed oil is made by mixing Mineral Oil and animal and vegetable oil in different proportions. It has good lubrication performance and has certain application in copper production.

4. Blend oil

Mixed oil is made by mixing Mineral Oil and animal and vegetable oil in different proportions. It has good lubrication performance and has certain application in copper production.

5. By far the most widely used in copper strip rolling is the blend oil

At present, the most commonly used oil in copper strip rolling is blending oil. The blend oil is made of refined mineral oil mixed with various functional additives, therefore, it has the characteristics of high oil film strength, not easy to crack, strong anti-oxidation ability, good surface precision, low roughness and high cleanliness after annealing. Because the heat capacity of mineral oil is small and the cooling effect is poor, the improvement of rolling speed is limited to a certain extent.

Copper Rolling Products and rolling stage of different choice of rolling oil, technical requirements are different. Should combine the concrete rolling condition to carry on the choice. Generally for hard rolled parts and rolling pressure, choose high viscosity of the Rolling Oil; and high-speed rolling mill should choose low viscosity of the rolling oil; The lubricating oil with good lubricity should be selected when rolling Copper Thin Strip and ultra-thin strip. In order to ensure the best lubrication effect of Copper Strip rolling, uniform oil film is used on the surface of copper strip to avoid sticking roll caused by too thin oil film or too thick oil film which makes the surface cleanliness of annealed copper strip low. At present, the oil used in the rolling oil is generally a blend of oil.
