Malinga ndi kuchuluka kwa mavalidwe ndi kuvala kwa ma induction olimba, mfundo zotsatirazi zitha kuganiziridwa:
1) Kutentha kwa induction kumagwiritsidwa ntchito kuzimitsa pamwamba pa chogwirira ntchito, chomwe chimathandizira kwambiri kukana kwa ntchito yoyambirira yosazimitsidwa.
2) Poyerekeza ndi magawo wamba olimba olimba, magawo olimba a induction amathandizira kukana kuvala chifukwa cha kuuma kwapamwamba komanso kusakhala ndi decarburization.
3) Kukana kwamphamvu kwa magawo olimba a induction opangidwa ndi chitsulo chapakati cha kaboni ndi chotsika kuposa cha magawo olimba opangidwa ndi carburized chifukwa cha kuuma kwapamtunda komanso kukhala ndi kaboni.
