Servo STEEROL C 17 (B) is a water soluble Rolling oil.It is synthesized with highly refined base stock and performance based additives. The water acts as a coolant and the oil acts as a lubricant. It is used in 20 HI Rolling Mills for rolling non – ferrous metal, where lubrication of bearing for IMR and work roll are with the same oil. It provides desirable co-efficient friction between the Roll bites. It is depend upon the type of metal surface, Roll diameter, rolling speed and percentage reduction.It is oil-in- water emulsions(typically with 2 to 5% oil concentration).
