Effect of Boron on the Melting Dynamics of Iron Base

Analyzed the melting process of iron base which contacted tightly with boron slag, established the boriding melting dynamical model of iron base and calculated the melting rate of pure iron. The melting rate of pure iron is not only decided by heat transfer rate, but also related to the mass transfer rate of boron. With the resolving of the model, we can know that the melting rate of pure iron is 3.41mm/min, and melting time is 15 min. When the speed of heating is high, the melting rate is mainly decided by diffusion.
