Yintoni iqondo lobushushu annealing emlonyeni wentsimbi umbhobho encinane frequency eliphezulu lokutshisa?

Umlomo wombhobho wetsimbi we-diameter encinci ufakwe kwi-furnace yokumelana neqondo lokushisa eliphezulu le-840 ℃; xa kusetyenziswa ukufudumeza kwe-high-frequency induction, ukuze kuphunyezwe injongo yokubuyisela kwakhona, iqondo lokushisa langempela lobushushu bomlomo wombhobho wentsimbi encinci yi-840 ℃.
