Wet temper oil is used for temper rolling process of finishing the surfaces of annealed steel sheets or hop-dip coated steel sheets with high roughness roll. Having excellent cleaning and anti-rustings, these are classified into wet temper oil for galvanized steel sheets and that for general steel sheets. These fluids diluted with ion-exchange water are sprayed director to steel sheets and rolls.
