high temperature Sintering Furnace for NdFeB
High Temperature Sintering Furnace Equipment Usage and Features
High vacuum grain boundary diffusion furnace is for the NdFeB production enterprises to use heavy rare earth metal element boundary diffusion process and research and development of special equipment.
Through the grain boundary diffusion method to make heavy rare earth metal elements effectively into the magnet grain boundary around, while reducing the use of heavy rare earth metal elements. In the realization of the magnet to increase the coercivity while avoiding the remanence decline.
With the furnace cavity clean, high vacuum, uniform diffusion, low cost, high efficiency, automatic control, simple operation, for the NdFeB metal diffusion production process to provide the ideal environment and means.
