Abstract：Al-Ti-B is one of the most commonly used refining agents for aluminum alloys.In the process of field use,there was a problem that the refining ability cannot be fully developed.The effects of Al-Ti-B addition time on Al-Ti-B absorptivity and microstructure refinement were studied.The results show that the addition time is inversely related to the absorptivity and the effect of microstructure refinement.The absorptivity and refining effect of element B are gradually improved when the time node of adding Al-Ti-B alloy is delayed.The proper time to add Al-Ti-B in the casting ladle is 8 min after the start of degassing.
