Abstract

A method of processing steel strip such that the steel strip can be temper rolled at the increased speeds and better surface texture control of prior art dry lubricants, yet the steel strip can be temper rolled with less frequent replacement of temper mill working rolls. Further, the resulting steel strip has increased stretchability and can be temper rolled to achieve sufficient reduction of YPE at lower working roll pressures and/or lower strip tension, previously only effective when the steel strip was lubricated with a wet lubricant film. Enhanced corrosion resistance is another advantage of this process.
