KHOOM Npe
Cov xaim feem ntau yog tsim los ntawm EAF / VD / LFfollowed los ntawm electroslag refining (ESR) yog tias tsim nyog rau cov laj thawj tshwj xeeb.
Cov kab ntawv thiab, qhov tsim nyog, kev zam txim yog raug kuaj rau ultrasonic kuaj raws qib sib txawv raws li cov neeg yuav khoom' cov tseev kom muaj.
Cov kab tuav feem ntau yog muab ci ci rau hauv qhov muag mob.
