Multifunctional electron beam area smelting furnace

The utility model belongs to the technical field of ultra-pure material preparation, and particularly relates to a multifunctional electron beam area smelting furnace which comprises an upper feedingand clamping mechanism 1, a furnace body 2, an electronic gun 3, a vacuum system 4, a rack 5, an electronic gun moving mechanism 6, a lower feeding and clamping mechanism 7, an observation window 8, acontrol box 9, a high-voltage power supply, an automatic control system and a water cooling system. An upper material clamping head is arranged at the end, stretching into the furnace body 2, of theupper feeding material clamping mechanism 1, and a material rod to be melted is clamped on the upper material clamping head. The function of synchronous and coordinated movement of the gun body and the feeding and clamping mechanism can be achieved, diversified smelting materials can be achieved, the structure is compact, smelting of bars with the diameter of 50 mm can be achieved, the layout is reasonable, and maintenance
