Typical characteristics

Manufacturer's description

Walzoel BM 71/W-27 covers two specialised ExxonMobil rolling oils. Walzoel W-27 is a fully formulated aluminium rolling oil based on a high quality mineral oil cut with specially selected non-staining additives, particularly suited to rolling aluminium sheet and strip; it provides clean annealing without prior degreasing and good reduction capability for aluminium alloys, with Wyrol 8 available as the corresponding additive top-up package. Walzoel BM 71 is a copper and copper-alloy rolling oil made from high quality base oils and carefully selected additives to enhance lubricity and oxidation stability, suited to four-high and six-high mills where roll bearings are not lubricated by the rolling oil; its low viscosity provides excellent cooling. Walzoel W-27 meets US FDA Regulation 21 CFR 178.3910, allowing use in the production of food packaging material, and has extremely low aromatics content and low odour. Walzoel BM 71 offers excellent filterability in systems using active and/or inactive earth filter media, contains no sulphur-containing additives, and has a very low additive depletion rate, with very good oxidation resistance that prevents the formation of dissolved copper soaps.

Applications

• Walzoel W-27: particularly suited for rolling aluminium sheet and strip, providing clean annealing without the need for degreasing beforehand.
• Walzoel W-27: additives provide good reduction capability for aluminium alloys; the corresponding additive package Wyrol 8 is available for top-up.
• Walzoel BM 71: particularly suited for rolling copper and copper alloys on four-high and six-high mills where roll bearings are not lubricated by the rolling oil.
• Walzoel BM 71: low viscosity provides excellent cooling properties; very good oxidation resistance and the absence of acidic components prevent the formation of dissolved copper soaps.

Performance & benefits

• Meets US FDA Regulation 21 CFR 178.3910, Surface Lubricants Used in Manufacture of Metallic Articles.
• Clean annealing properties reduce the potential for production rejections.
• Compliance with FDA regulation allows use in production of food packaging material.
• Extremely low aromatics content and low odour make the roll oil acceptable to workers and the environment.
• Reduced evaporation due to the extremely narrow boiling range of the base oil.
• Excellent filterability in filter systems using active and/or inactive earth; additive depletion is low in systems where only inactive earth is used, and enhanced filterability keeps the rolling oil clean in service.
• No sulphur-containing additives.
• Very low additive depletion rate.
