• Development of a rational roll pass design for a rolling

    2013-5-8 · A new technique is developed to analyze the roll pass design of a section rolling mill. Metal forming nonuniformity and efficiency coefficients, which determine the degree of working of a metal microstructure in rolling of section bars, are used as performance criteria. The system of roll passes intended for the production of a round bar 28 mm in diameter is used as an Effect of pass schedule and groove design on the metal,2019-4-9 · flow. So, the design of the roll groove geometry and the roll pass sequence are important aspect to be assessed. The pre-diction of the load and torque with different groove designs plays an important role in order to improve the draft during rolling. The roll grooves in a roller and the roll pass sequence in a hot rolling mill are usually
