Lubricants
Metal rolling is the process of stretching a piece of sheet metal to a certain thickness by increasing its length. The process requires lubrication to control the friction between the rolls. Friction control is critical; low friction is desirable in some places but if too low in other contact areas it can cause the rolls not to flatten the metal effectively, creating pits and smears. The most important characteristics of rolling oils are to cool the metal and work rolls whilst providing the required lubrication to the roll bite and protecting both from corrosion.
We are a global supplier of synthetic lubricant base oils and additives for use in hot and cold rolling, with ferrous and non-ferrous metals. We know that many factors can affect the process, such as:
- Water quality
- Roll speeds
- Roll configuration
- Required deposit levels
- Hardness of metal being rolled
- Final thickness
- Temperature of operation
Proving the performance of our products
Test methods we use to differentiate the rolling oil product range in our laboratories include Thermogravimetric Analysis (TGA) and Laser diffraction particle sizing.
