Roll Selection
How rolling mills actually run: stand groups, temperatures, quench lines and which roll grade each stage needs. Each article is written to help a mill engineer make one decision.
In roughing stands a crack or a break ends the life of a roll sooner than wear. The grades used in each type of mill, how to choose adamite or SG iron pearlitic, and how to step hardness across the stands.
Shore C is a rebound test, not a wear guarantee. How the number is measured on a roll, why it drops with depth, where each Vimco grade sits, and why harder is not always better.
HSS resists wear, ICDP resists sticking and cracking. What the published wear figures really compare, which stand suits which grade, and how to judge the switch on cost per tonne.
