Cooling Bed in a Rolling Mill during Convective Heat Transfer
Abstract—The cooling of a metal during heat removal via radiation and convection is considered. The cooling beds used in modern section rolling mills are calculated using the quantity of heat transfer. A formula is proposed for calculating the time of metal cooling from 850 to 50°C. It gives a result 1.78 times less than the formula that …
Hot Lubrication Rolling | SpringerLink
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.
