Description

technical field [0001] The invention relates to a control system, in particular to a cold cathode electron gun smelting furnace control system, and also relates to a metal ingot smelting method, which belongs to the smelting field. Background technique [0002] Under vacuum conditions, using high-energy electron beams emitted by electron guns to convert kinetic energy into thermal energy for metal smelting technology is one of the most advanced metal smelting technologies at present, and it is widely used in the smelting and purification of expensive and refractory metals. [0003] Electron guns can be mainly divided into hot cathode guns and cold cathode guns. The cathode of the hot cathode gun adopts a tungsten wire structure, and the cathode of the electron gun needs to be heated to above 2000°C during the working process, which has the disadvantages of many faults, high energy consumption, and high cost. [0004] The cathode of the cold cathode gun adopts an aluminum bl...

AI Technical Summary

Problems solved by technology

[0005] However, the existing hot cathode gun smelting furnace has many faults, high energy consumption, and high cost. At present, it is not possible to accurately control the cold cathode electron gun to complete the metal ingot smelting. Furthermore, a system that can be accurately controlled and easy to operate is urgently needed
