三辊斜轧钢管内扩值与管壁变形量和径壁比的关系
THE RELATIONSHIP BETWEEN INNER-EXPANSION VALUES AND WALL FORMATION AMOUNT & D/T RATIO IN THREE-ROLL CROSS ROLLING
-
摘要: 提出了计算三辊斜轧钢管内扩值的新方法,分析了三辊斜轧过程管壁变形时的金属流动特点。Abstract: A new method for calculating inner expansion values of tubes rolled by a three-roll mill is put forward based on rolling experiments on a φ108mm three-roll mill, and the metal-flow features in wall compression formation during three-roll cross-rolling are analysed.
