EBCHR (under high vacuum) allows the vacuum melting furnace, refining and solidification of the final ingot separated, preventing the molten metal flows into the ingot while insoluble components, which provides sufficient residence time to separate the volatile and the reaction of melting rate, and it can be achieved that the residue was evaporated to an impurity element is not required to detect almost undetectable level. Cr volatilization problems exist, the charge must be replenished in the. it's reported in the literature, the content of oxygen and nitrogen in the alloy is significantly reduced, non-metallic inclusions through the water-cooled liquid separator is mechanically removed or decomposed at the heat treatment intense electron beams, so the cleanliness of the material is better than other methods of melting the alloy.
Electron beam melting slag film (EBFFM) is a certain percentage of the slag film on the metal surface cooling bed, non-conducive to slag film covering part of the degassing of molten metal and slag film covering part helps reduce evaporation losses, complete removal of impurities task. Less work reported in this area.
