摘要
电子束熔炼具有高真空、高能量密度、可精准控制等特点,被广泛应用于难熔金属行业。本文依托核工业理化工程研究院电子枪技术和LT102真空装置,设计研制了一套难熔金属电子束熔炼用供料、熔铸拖锭装置。主要阐述了供料、熔铸拖锭装置的设计技术要求,针对难熔金属进行了熔炼功率计算,并对结构设计功能进行了详细介绍。所研制的供料装置具有多工位、换料功能,拖锭装置具备水冷、下拉、旋转功能。最终装配测试的供料、熔铸拖锭装置性能满足设计要求,整体熔炼实验中设备运行良好。
Electron beam melting has the characteristics of high vacuum,high energy density,and precise control,and is widely used in the refractory metals industry.Relying on the electron gun technology and the LT102 device of the Research Institute of Physical and Chemical Engineering of Nuclear Industry,a set of feeding,melting,and casting ingot dragging devices for electron beam melting of refractory metals were designed.The technical requirements for the design of feeding,melting,and casting devices are mainly described,the smelting power for refractory metals is calculated,and the structural design function is introduced in detail.The developed feeding device has multiple work stations and refueling functions.The dragging device has functions of water cooling,pull-down,and rotation.The performance of the feeding and casting dragging device for the final assembly test meets the design requirements,and the equipment runs well in the overall melting experiment.
