Development of a rational roll pass design for a rolling
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 example to analyze Improvement in the rollpass design of the continuous lightsection mill 250 Assistant Shop Manager V A Satskii RollPass Design Engineer V Shum Authors Assistant Shop Manager V A Satskii View author publications You can also search for this author in PubMed Google Improvement in the rollpass design of the continuous Roll Pass Design satyendra; June 18, 2014; 1 Comment ; Long products, roll grooves, Roll pass, Roll pass design, rolling mill, rolls, sections,; Roll Pass Design Long products are normally rolled in several passes, whose numbers are determined by the ratio of the initial input steel material (square or round billet or bloom) and final cross section of finished productRoll Pass Design – IspatGuru
