Roll Pass Design For Blooming Mill

This book discusses as well the different types of rolls for various rolling mills, including blooming, plate, sheet, sheet bar, small section, heavy product, skin passing, and cold rolling mills. the final chapter explains the purpose of roll pass design to ensure the maximum output at minimum cost as well as to reduce the roll wear to a minimum.

The 10pass example should be fine if youre running nonnotched, postcut mild steel. if the section is notched, precut, or highstrength material, youll need more passes to achieve desired results. additional passes allow the material to flow through the mill with less strain. design the layout and roll tooling
