本文研究了用提高軋制溫度(預先加热)的方法来改善6合金的塑性和降低其变形阻力的可能性,目的是为了提高軋管机的生产率及改善管材的质量。軋制溫度范圍通过实驗方法确定。选擇軋制溫度的一般条件如下:在强化变形的条件下,保证材料能經受高度变形;为了保持冷变 This paper investigates the possibility of improving the ductility and reducing the resistance to deformation of the 6 alloy by increasing the rolling temperature (pre-heating) in order to improve the productivity of the tube rolling mill and to improve the quality of the tube. The rolling temperature range is determined experimentally. The general conditions for the selection of the rolling temperature are as follows: under conditions of intensive deformation, the material is guaranteed to withstand a high degree of deformation; in order to keep the cold
