本发明提供一种免混料的电子束冷床熔炼炉用下料装置及下料方法，包括设于电子束冷床熔炼炉真空熔炼室顶部的称料仓，该称料仓底部设有与冷床垂直的下料口、顶部设有进料口，且下料口上设有第一开闭门，进料口与竖直下料管相连，竖直下料管通过第二开闭门与上方的储料仓相连，储料仓顶部通过第三开闭门与料斗相连，储料仓顶部通过真空管与真空泵相连。使储料仓、称料仓形成与真空熔炼室相适应的真空环境，合金料进入称料仓，称重，进入真空熔炼室熔化并凝铸成锭，无需混料、压块，就能满足熔炼要求。

The invention provides a discharging device and a discharging method for a mixed-material-free electron beam colding bed smelting furnace. The discharging device for the mixed-material-free electron beam cold bed smelting furnace comprises a weighing bin which is arranged at the top of a vacuum smelting chamber of the electron beam cooling bed smelting furnace, a discharging opening perpendicularto the cooling bed is formed in the bottom of the weighing bin, a feeding opening is formed in the top of the weighing bin, a first opening and closing door is arranged on the discharging opening, thefeeding opening is connected with a vertical discharging pipe, the vertical discharging pipe is connected with an upper storage bin through a second opening and closing door, the top of the storage bin is connected with a hopper through a third opening and closing door, and the top of the storage bin is connected with a vacuum pump through a vacuum tube. The storage bin and the weighing bin forma vacuum environment matched with a vacuum melting chamber, the alloy material enters the weighing bin, weighing, feeding into the vacuum smelting chamber for melting, casting into ingots, material mixing and briquetting are not needed, so that the smelting requirements can be met.
