WALZOEL BM 71/W27
Mobil industrial , France
Product Description
Walzoel W-27 is a fully formulated aluminium rolling oil based on a high quality mineral oil cut with specially selected non staining additives, which permit required lubrication characteristics to be obtained.
Walzoel BM 71 is a copper and copper alloys rolling oil that consists of high quality base oils and carefully selected additives to enhance lubricity and oxidation stability.
Features and Benefits
Walzoel W-27:
• Meets US FDA Regulation 21 CFR 178.3910, Surface Lubricants Used in Manufacture of Metallic Articles
• Clean annealing properties reduce potential for production rejections.
• Compliance with FDA regulation allows use in production of food packaging material.
• Extremely low aromatics content and low odor makes the roll oil acceptable to workers and the environment.
• Reduced evaporation due to the extremely narrow boiling range of the base oil.
Walzoel BM 71:
• Excellent filterability characteristics in filter systems using active and/or inactive earth. Additive depletion is low in systems, where only inactive earth is used. Enhanced filterability allows clean rolling oil in service.
• No sulphur-containing additives.
• Very low additive depletion rate.
Applications
Walzoel W-27:
Walzoel W-27 is particularly suited for rolling aluminum sheet and strip. It provides clean annealing without the need of degreasing beforehand. The additives used in Walzoel W27 provide good reduction capability for aluminum alloys. For additive top-up the corresponding additive package Wyrol 8 is available.
Walzoel BM 71:
Walzoel BM 71 is particular suited for rolling of copper and copper alloys on four-high and six-high mills where roll bearings are not lubricated by the rolling oil. The low viscosity provides excellent cooling properties. The very good oxidation resistance and the absence of acidic components prevent the formation of dissolved copper soaps.
