Cold Strip Rolling Mill


In the cold strip rolling mill process, steel sheets become thinner and form to the desired shape. The advantages of cold strip rolling mill compering to hot strip rolling mill are better thickness Tolerance and lower oxidation. In cold strip rolling mill, due to the nature of the process, the temperature of the product and rollers rise, and therefore rollers should be cooled by spraying (the same way as hot strip rolling mill). Since cold strip rolling mill requires lubrication, existence of oil is essential. For cooling and lubricating the rollers of the cold strip rolling mill usually mixture of water and oil is used (5% oil, 95% water). Then this mixture that is heat in contact with product and rollers, cooled by a heat exchanger to be sprayed to the rollers at optimum temperature. As the last step, in cold strip rolling mill processes, steel may be annealed.
