Abstract

Abstract: 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.

Key words: electron beam melting, feeding device, casting towing device, vacuum melting furnace, refractory metal
