[Abstract]:The effect of adding 0.1% Al-Ti-B refiner with different mass fraction in 1100 aluminum alloy and electromagnetic oscillation field during casting and rolling on the microstructure refinement of slab casting was studied. The results show that the microstructure refinement effect of the slab subjected to electromagnetic oscillation field in the process of casting is higher than that of the ordinary slab casting under the condition of adding the same content of Al-Ti-B. At the same time, it is found that when the mass fraction of the refiner is 0.1% and the electromagnetic oscillation field is applied in the process of casting and rolling, the refining effect is satisfactory, and its microstructure is better than that of the conventional casting rolling with 0.4% fining agent. Therefore, electromagnetic oscillation casting can greatly reduce the amount of refiner, reduce element segregation, and improve the internal quality of casting and rolling billet.
