The technological conditions of the continuous solidification of copper-chromium alloy and their matching relationship were studied, as well as the microstructure of copper-chromium alloy and the formation of surface defects. The results show that when the mold height is 10-25mm, the cooling distance is 25mm, the alloy temperature is 1210-1280 ℃, the pulling speed is 0.2-1.0mm / s and the cooling water volume is 720L / h, Cu-0.6% Cr alloy material.
