摘要：

Continuous casting composite is a new method to prepare high performance metal composite materials. Improving continuous casting speed has important practical significance for improving production efficiency and reducing production cost. The increase of continuous casting speed will significantly affect the solidification behavior and billet quality. In this study, pure copper clad Q235 steel wire with outer diameter of 8.7 mm and core diameter of 6 mm was prepared by continuous casting composite method; and the influences of process parameters on the surface quality, copper layer microstructure, interfacial diffusion layer thickness and interfacial bonding strength were studied. The results show that copper-clad steel wire with low surface roughness value, finer grain of copper layer and high bonding strength can be fabricated under processing parameters of composite temperature of 1150 ℃, primary cooling water flow of 400−800 L/h, secondary cooling water flow of 100 L/h and continuous casting speed of 300−420 mm/min. This provides a foundation for large-scale production of copper-clad steel wires. © 2023 Central South University of Technology. All rights reserved.
