Study on Hot Extrusion Process of Leaded Zinc-copper Alloy

对含铅锌白铜的热挤压工艺参数进行研究。实验结果表明:在挤压温度780～880℃,挤压速度400～600mm/s,挤压力15MPa,能够挤压出含铅锌白铜铜圆杆;热挤压后,含铅锌白铜合金杆的抗拉强度是460.33MPa,伸长率为19.4%。

The hot extrusion process parameter of leaded zinc-copper alloy was researched. The experiment results show that, when extrusion temperature is 780-880℃, the extrusion speed is 400-600 mm/s, the extrusion pressure is 15MPa, the leaded fine-copper round bar can be extruded. After hot extrusion, the tensile strength of leaded zinc-copper alloy bar is 460.33 MPa, the elongation is 19.4%.
