  • (PDF) A New Method for Roll Pass Design

    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

  • Roll Pass Design for Round Bars ScienceDirect

    1990-1-1 · In the paper a general computer approach strategy concerning the roll pass design for round bars is presented. It deals with roughing and finishing sequences optimizing the pass geometry. The results of the calculation, applied to steel bars, show a good agreement with the geometrical data found in the technical literature or pertaining to
