Cold Rolling Oils

Wocorol 5000 SeriesThe Wocorol 5000 SERIES of products represents a quantum leap forward in rolling oil technology. The base oil and additives in the Wocorol 5000 Series were carefully selected after extensive laboratory testing. This testing allowed Wallover Oil Company to formulate a product with three major advantages over more traditional rolling oils. First, Wocorol 5000 Series products are formulated with additives that will leave no residue on the rolled strip, even with the lower annealing temperatures seen on copper alloys. It is by far the cleanest running rolling oil available. Second, Wocorol 5000 Series has a heavy-duty additive package that allows greater reductions per pass. This means your strip can be rolled to final gauge with fewer passes, therefore eliminating an intermediate annealing process. Third, all of the above benefits were achieved while lowering the base oil’s viscosity to a bare minimum. This dramatically enhances surface finish. Also, the light viscosity will inherently carry less dirt, improving your filtration capabilities without any equipment changes. Wocorol 5000 Series are designed specifically for stainless steel. It has also proven to be extremely effective on titanium and beryllium copper.

Founded in 1863, Wallover Oil Company is one of the oldest independent manufacturers of industrial lubricants in the United States today. With more than a century of experience, a diverse product line and a commitment to provide outstanding service, it is little wonder that Wallover is also one of the largest manufacturers of premium lubricants and metalworking fluids in the industry.

Our experience with cold rolling oils dates back more than 60 years when we blended our first product for a Sendzimir Mill rolling stainless steel in Pennsylvania. Our products today are sold worldwide for all types of metals, including carbon and stainless steels, titanium, copper, brass, bronze, beryllium copper and aluminum alloys. With customized products, customized service, extensive R&D and laboratory facilities to maximize your mill’s performance and maintain your system, Wallover Oil Company is the best choice to provide your rolling oil requirements.

Wocorol 6000 SeriesThe Wocorol 6000 SERIES of products is formulated for applications where finish, cooling ability and strip cleanliness are the primary requirements of your rolling oil. The straight cut 60 SUS base oil is extremely stable and displays good natural resistance to oxidation. With its low viscosity and additive package for wetting and extreme pressure, the Wocorol 6000 Series of products will aid greatly in shape control and other heat related problems. These products burn extremely clean in both strip and bell annealing and were designed for finish rolling of stainless steel, copper alloys and titanium.

Wocorol 7000 SeriesThe Wocorol 7000 SERIES of products represent our most versatile rolling oils. The 70 SUS base oil is straight cut and exhibits excellent natural oxidation resistance, cooling ability, rust protection and demulsibility. Wocorol 7000 Series, with their heavy additive package, are a good selection when large reductions are being taken. This additive package gives even wetting along the entire length of the work roll providing maximum cooling while eliminating surface to surface contact with specially selected extreme pressure agents. Providing excellent surface conditions in breakdown or finish rolling, with varied speeds and reduction schedules, the Wocorol 7000 Series, with its broad product mix, will do the job.
