Abstract

The numerical simulation model of single roller melt spinning for rapid quenching process of NdFeB alloy was built, and the vacuum chamber, cooling roller and sample were taken into account as a system. The existing mature technology was in order to verify the correctness of simulation. The rapid quenching ribbons with different roll speeds were used as the simulation objects. The results of the numerical simulation and experiments show that the validity of the model has been testified and the reasons of the formation of complete quenching ribbons and by-product have been explained. The experimental thickness of the ribbons is proportional to the theoretical thickness. In the same spray condition, with the roll speed increasing, the thickness decreases linearly. At the speed range of 25–30 m·s−1, the simulated calculation date is close to the experimental date, which can be considered as an ideal technological parameter.
