D1 is the outer diameter of the roll. D2 is the diameter of the roll when it is scrapped, that is, rolls larger than this diameter can be used in the rolling mill and have the same performance as when delivered. Below this diameter, the performance of the roll cannot be guaranteed. D3 is the diameter of the core material. Figure 5b explains:
