[0002] Electron beam melting refers to a vacuum melting method that converts the kinetic energy of a high-speed electron beam into heat energy as a heat source for metal melting under high vacuum. Abbreviation: EBM. This melting method has the characteristics of high melting temperature, adjustable furnace power and heating speed, and good product quality, but there are also problems such as low metal recovery rate, large specific power consumption, and the need to carry out melting under high vacuum state.
