The first principle of cooling system design is consideration of all heat sources (See Figure 4). Heat is primarily generated in the roll gap (roll bite) from deformation of the metal and friction, at the direct interface between the product and rolls. Heat energy is related to the actual electrical energy driving the mill stand.
