Two-machine two-flow electron beam cold bed smelting furnace

Abstract

The invention discloses a two-machine two-flow electron beam cold bed smelting furnace. The furnace comprises a double-layer water-cooling structure furnace body, a high-power electronic gun arrangedon a furnace cover, transverse feeding systems connected to the side faces of the furnace body, a smelting crucible connected to the feeding system and arranged in the furnace body, crystallizers connected to a smelting crucible refining area, ingot pulling devices connected to the crystallizer in a matched mode, an observation window used for observing the condition in the furnace and a matched vacuumizing system. The two transverse feeding systems are arranged on the two sides of the furnace body respectively, the two crystallizers and the two ingot pulling devices matched with the crystallizers are arranged, and the smelting crucible refining area is provided with two melt guide openings which are connected with the crystallizers respectively. According to the furnace, the smelting amount each time is increased, two cast ingots can be produced at the same time, and the ingot pulling production efficiency and the product specification diversity are improved.

Description

technical field [0001] The invention belongs to the technical field of electron beam smelting equipment, in particular to a two-machine, two-stream electron beam cooling bed smelting furnace. Background technique [0002] At present, the electron beam cooling bed melting furnace is one of the core equipment for smelting refractory metals, and plays an important role in the smelting of high-end materials. Electron beam melting furnace is a special vacuum metallurgical equipment. The high-energy electron beams of dozens to hundreds of KW can be gathered by the electron gun to generate high temperature and high energy density. When the high-energy electron beams are focused on refractory metal materials such as tungsten, tantalum, niobium, and zirconium, they will be melted and removed. Remove impurities to achieve the purpose of smelting and purification. During this period, the metal in the high-temperature melting area needs to enter the molten pool drop by drop, cool and ...

AI Technical Summary

Problems solved by technology

The current electron beam cooling bed melting furnace can melt about 10 tons of ingots each time, and the melting volume cannot meet the demand, and can only produce one specified ingot at a time, and the variety is single, which cannot meet the needs of diverse specifications.
