On the basis of analysis of the rapid melting mechanism involved in process, the differences of these three kinds of devices are compared in terms of the requirements for the solid pitch, melting efficiency, cleaning, control and daily maintenance.

Under laser pulse heating, a non-equilibrium heat and mass transfer model based on the non-Fourier law is developed for surface rapid melting and solidification process (RMSP) of Uniphase binary alloys.

In this paper, the application of quick-fuse in thyristor converter is introduced and the choice of parameter.

Based on the simulative experiment of the relationship between the values of resistance and current and temperature,the paper presents the theoretical basis for safe application of the quick fuse.
