A Tangible Value to the Leading Cold Rolling Mills is Cold Rolling Oil/Lubricant

Promising performance and quality of cold rolling oil

The cold rolling mills exist in several sizes and each mill entails a definite lubrication method depending on the size of the mill. Larger cold rolling mills use cold rolling oils both for lubrication and as well as cooling. As oils such as hydraulic fluids may pollute the cold rolling oil, therefore, an exact hydraulic oil should be used for the cold rolling mills, in order to assure the performance of cold rolling oil and the quality of the metal surface.

A small quantity of cold rolling oils is used by some smaller cold rolling mills in order to lubricate the strip and rolls, which is often referred to as minimum quantity lubrication. Later, the decreasing unit removes the used cold rolling oil stuck on the strip.

Choosing the Right Hydraulic oil for Right Cold Rolling Mills

A neat cold rolling oil is needed for medium-sized or large cold rolling mills for lubrication as well as for cooling. The outcome of this is high cold rolling oil flow and the necessary recovery of the cold rolling oil under the cold rolling mill. After filtration, the cold rolling oil is reused in the cold rolling mill. Filtration systems are designed to purify the oil by removing the metal particles. However, due to adulteration, oils such as hydraulic fluids, cannot be removed and its leftovers are still present in the cold rolling oil. Thus, it is significant to choose the right hydraulic oil for a right cold rolling mill.

The Adverse Effects of Unsuited Hydraulic Oils

The cold rolling oil gets contaminated once hydraulic oil leaks into it, resulting in various adverse effects. The effects are listed below.

While unwanted extracts from the hydraulic oil are added to the cold rolling oil, the additive levels of the cold rolling oil will faintly decrease.

By contamination with the higher viscosity hydraulic oil, the viscosity of the cold rolling oil will increase.

The actual performance of the cold rolling oil will condense, leading to an inferior productivity and a lower quality of the produced metal strip.

The Right Hydraulic Oil for Cold Rolling Mills

Most of the cost-effective standard hydraulic fluids are zinc based in order to protect the hydraulic system against wear. However, when there is a remaining oil on the metal surface, especially when it enters the annealing step, these fluids can cause stains on the surface of the metal strip.

Therefore, it is strongly recommended to use only cold rolling oil compatible hydraulic fluids should be in the cold rolling mills. There are numerous other standard additives that are unwanted in the cold rolling oil, and besides the additives, the viscosity also differs. The cold rolling oil has a rather low viscosity, approximately ranging from 4 to 9 mm2/s in reversing mills, and the viscosity of hydraulic fluids is standard 46 or 68 mm2/s.

Q8 Oils oil for Cold Rolling Mills

The Q8 Oils has developed a variety of hydraulic products and a wide range of cold rolling oil for use in cold rolling mills. The hydraulic oils are fully compatible with cold rolling oils. An interesting example is the Q8 Holst CR 15 hydraulic oil, which is specifically developed on request of a German OEM for use in their designed and manufactured cold rolling mills. And on the other hand, Q8 Bach R cold rolling oil, for manufacturing ferrous and non-ferrous metals. These are such type of lubricants, which are appropriate for all types of mills and also permitted by leading rolling mill manufacturer.
