White PaperSuccessful Execution Of Roll Cooling Strategies

coolant is used for multiple reasons: 1) to cool rolls; 2) to provide lubrication (in cold mills); 3) to control product temperatures (for example in inter-stand cooling stations in hot mills); and 4) to control the thermal profile (in most cold sheet mills, many other cold mills, and increasingly even in hot mills).

Modeling The Thermal Regime Of A Cold-Rolling Mill With

with the higher rolling speeds used in modern cold-rolling mills, proper roll cooling has become a critical factor in avoiding problems of excessive roll spalling and poor thermal crowning.



cooling system. problems of this kind can never really be calculated but they have a detrimental effect on all rolling schedules including stresses in the roll. as regards “abnormal” rolling conditions - which are more or less very “normal” for rolling mills - roll damage often occurs with consequences for the mill and the rolled product.
