| Using metallographic analysis method to study the influence of continuous casting parameters on AgCu4Ni0.5 alloy solidification structure. The result shows that when both the solution temperature and casting speed are low, the solid-liquid interface temperature gradient of alloy is comparatively low and the solidification time is comparatively long, which is beneficial to aggregate nickel. Increasing the solution temperature and speeding up the continuous casting speed, the content of Cu, Ni were close to the nominal composition and Ni evenly distributed in the matrix and obtained the uniform composition casting billet. |
