Our lubrication experts will help you make the right choice.
We have a lot of knowledge and experience in the lubrication of aluminium surfaces through hot and cold rolling, and through fabrication processes such as can making and automotive pressed panel production. We can use this knowledge to help you select your lubrication. Furthermore, we will evaluate its performance at every process stage so you’ll be confident you’ve made the right choice.
If you have a process problem linked to your lubricant, such as smut generation, we can help you solve it. Our decades of experience of working with lubricants mean that we’ve probably seen your problem before and so will be able to solve it quickly.
Lubrication is an essential part of the rolling process enabling aluminium to be converted from cast slab/ingot into a usable industrial form. Over the last 35 years major changes have taken place in rolling lubricant development and understanding. It is now accepted that the rolling lubricant influences mill productivity and the quality of metal produced.
There are three main functions of a lubricant in aluminium rolling. These are to prevent excessive contact between the rolls and aluminium surface; to remove heat generated by friction and deformation; and to carry fines and debris from the roll bite area to the filter.
The majority of hot rolling mills are lubricated and cooled by oil-in-water emulsions. However, the majority of cold and foil rolling mills are lubricated and cooled by oil-based lubricants.
In hot rolling the major component of the emulsion is water, with less than 10% oil phase. With cold and foil rolling the base oil is the major component, accounting for more than 90% of the total lubricant volume.
In all rolling lubricants the base oil functions as a solvent for the additive components which provide load bearing capacity and control friction in the roll bite.
