本文在实验研究民主德国 ＥＭＯ－２００型电子轰击炉的基础上，设计并研制成功 ５００ ｋＷ电子轰击炉。它是熔炼稀有，难熔、高纯金属运行中的最大功率的国产炉子． 作者研究并改善了由于电子束在磁浸没场中的不适应性，引起电子轨迹偏离轴向而增加 了对电子的截获率．进而在研制中发现热阴极和聚束极间距的最佳值，以及阴极的合理 装置结构。使枪的性能大为改善。
Based on the experimental study of EMO-200 electron bombardment furnace in Germany, a 500kW electron bombardment furnace was designed and developed. It is a home-made stove for smelting rare, refractory, high-purity metals in operation at maximum power. The authors investigated and improved the interception of electrons due to the inadaptability of the electron beam in a magnetic immersion field, causing the electron trajectories to deviate from the axial direction. And then found in the development of hot cathode and bunching pole spacing the best value, as well as the cathode of a reasonable device structure. Make the gun performance greatly improved.
