电渣精炼 [diàn zhā jīng liàn]
[冶] electroslag refining
- 金属镍在电渣精炼前需用氩弧焊焊接接长，为保证焊接接头具有足够熔深，需要大参数进行焊接。
Nickel rod needs to be lengthen by argon arc welding before the electroslag refinements, large welding parameters are needed to assure the sufficient penetration. - 发达国家由于采用了先进的炼钢技术，如真空炉外精炼，电渣重熔，真空电渣重熔及粉末冶金等，使钢材质量发生了质的飞跃。
A leap in the quality of steel products has been realized in developed countries due to the applications of such advanced steelmaking practices as VOD, ESR, VMR and PM. - 在电渣熔铸过程中控制自耗电极熔化末端锥头形状，扩大钢渣接触面积，可以加强精炼效果。
The smelting quality can be improved by controlling the shape of consumable electrode tip, which affects the area of the slag/metal interface in electroslag shaped casting process.
