(PDF) A New Method for Roll Pass Design Optimisation
Roll wear is amongst the key criteria for devising a rational roll pass design. Rolls in a hot mill have to withstand radial loads up to 12 MN and high temperatures in the range of 900 to 1300 oC. In addition to the obvious need for resistance to breakage there is the continuing component of roll wear that is critical to the economics of
