Sep 16, 2016 One key condition is a perfect pass design in the rolling mill. The paper deals with the models for a pass design calculation as well as a calculation of roll force and power demands for the rolling mill. On modern bar and rod mill, different types of mill stands are used, with 2‑roll, 3‑roll, and 4‑roll

Jan 01, 1990 The roll pass design of the intermediate pass is conducted in a way by means of which the spread.value falls within an admissible interval, so ensurmg a good rolled product. The roll pass design of a finishing round sequence follows the same general principles as of a roughing sequence. The height of the leading oval is defined by an iterative

The quality and productivity of hot rolled bar steel products strongly depends on hot rolling parameters such as strain, strainrate, temperature,groovedesignandrollingsequence. It influences the metal deformation behaviour within the pass and mill load requirement apart from roll wear. The metal flow behaviour in a hot rolling process is a
