摘　　要：A new copper strip production technology combined with continuous extrusion and rolling technology was proposed. The roll velocity must first be matched with the continuous extrusion velocity to achieve continuous extrusion and roll forming. The bite condition of continuous extrusion was determined, and the compatibility equation between the roll velocity and parameters such as the extrusion wheel velocity, reduction, and strip size was established through mechanical by plastic theoretical calculations. The finite element model of continuous extrusion and rolling was then established by using the TLJ400 continuous extrusion machine with a roll diameter of 200 mm. The relationship between the continuous extrusion and rolling velocities was determined through numerical simulations by software DEFORM-3D, and the accuracy of compatibility equation of velocity was verified.结合连续挤压和轧制技术,提出一种铜板带生产新技术——连挤连轧成形工艺。在连挤连轧成形过程中,保证轧制速度与连续挤压速度的匹配是实现连挤连轧成形的重要条件。通过塑性力学理论计算,确定连续挤压咬入条件,建立轧辊转速与挤压轮转速、压下量和板带尺寸等参数之间的协调方程。以TLJ400连续挤压机及直径为200 mm的轧辊为模型,建立连挤连轧成形的有限元模型,并利用DEFORM-3D软件对铜板带连挤连轧成形过程进行数值模拟,研究连续挤压与轧制速度的关系,验证连挤连轧速度协调方程的准确性。
