Since the cooling water between rolls or stands is widely used in the hot rolling process, the supply of lubricating oil needs to ensure that the lubricating oil is evenly distributed on the roll surface and cannot be washed away by the cooling water. There are three main supply modes of hot rolling lubricating oil (Fig. 1). Pre-mixing mode.
