Cooling and lubrication of hot rolling of aluminum alloys

The purpose of hot rolling cooling lubrication is to use effective lubricants to greatly reduce the friction between the roll and the deformed metal, as well as the additional deformation force of the metal caused by friction resistance, thereby reducing the energy consumption during rolling.
The use of effective anti-sticking and friction-reducing lubricants is conducive to improving the surface quality of rolled aluminum alloys.
Reduce roll wear and extend roll service life.
Utilize the cooling properties of lubricants, pass the lubricant, and control the temperature of the lubricant. Flow, injection pressure. Can effectively control the roll temperature and roll shape.

The functions of aluminum alloy hot rolling emulsion are
1. Reduce the friction between the aluminum plate and the roll during rolling,
2. Avoid direct contact between the roll and the aluminum plate and aluminum coil and prevent the roll from sticking to the aluminum plate,
3. Control the temperature and roll shape of the roll,
4. Dissolve or emulsify the machine lubricant that falls on the roll road.
The basic function of the emulsion is cooling and lubricating during hot rolling, in which water plays a cooling role and oil plays a lubricating role.

The components of aluminum alloy emulsion.
Mineral oil is mixed with one or more emulsifiers and various additives such as extruders, wetting agents, antioxidants, defoamers, biocides and the like.

Aluminum processing plants can mix hot emulsions themselves and can only produce ordinary aluminum plates and aluminum coils with low requirements on surface quality. They cannot produce PS plates can making materials and other products with high requirements on surface quality and high performance.
