电工用铜铜线坯连铸过程凝固结晶研究 Research on Solidification Crystallization in Continuous Casting Process of Copper Wire

本文主要研究连铸过程中冷却强度、连铸温度及连铸速度对电工用铜线坯连铸组织的影响，通过合理布置结晶轮冷却系统及确定合适的连铸温度和速度，最终得到呈中心对称的柱状晶穿晶组织铸坯，满足电工用铜线坯的性能要求。 This paper mainly researches the effect of continuous casting parameters on copper microstructure, including cooling intensity, casting temperature and speed. Through the reasonable arrangement of crystallization cooling system and appropriate casting temperature and speed, in the end, the center symmetric columnar crystals are formed in the billet to satisfy the requirement of the copper drawing stock for electrical performance.
