3. Length minimum and maximum. 4. Notching or secondary operations. 5. Reference to mating parts. 6. Attention to critical areas. If a wornout sample roll is submitted instead of a roll drawing, the manufacturer should take the time to reverseengineer the roll, make a new drawing, and get it approved by the customer to avoid any misunderstandings when the new roll tooling is delivered.

The selection of roll diameter is an important decision for rolling mill design. It is generally selected on the basis of strip thickness, the type of material to be rolled, maximum reduction to be given to the strip, the coefficient of friction, mill speed, etc. Large diameter rolls provide better rigidity and better cooling.

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.
