Kulimba koyamba kwa chitsulo cha manganese chochuluka ndi kochepa kwambiri, 220-250 HV yokha, koma khalidwe la chitsulo cha manganese chochuluka ndilakuti chikavuta kwambiri, chimakhala cholimba, ndipo kulimba kwake kumatha kufika 600 HV pambuyo pa nthawi yogwiritsidwa ntchito.
Njira yosatha ya chitsulo cha manganese yokwera ikufunika. 1. Kulimba koyamba kumakhala kwakukulu. 2. Lolani makulidwe ogwirira ntchito a chitsulo cha manganese yokwera awonjezere kuti mphamvu zake zosatha zigwiritsidwe ntchito.
Chitsulo cha manganese ndi chinthu chofewa, kuuma kwake koyamba ndi pafupifupi 220-250 HV, kuya kwa gawo lolimba la impact kuli pakati pa 10-15 mm, ndipo kuuma pakuphwanya kwakukulu kumatha kufika 600 HV. Mu ntchito zophwanya zazing'ono, gawo lolimba la impact limakhala lochepa, ndipo kuuma nthawi zambiri kumakhala pafupifupi 350-500 HV.
Njira yodalirika kwambiri yowunikira kukana kwa chitsulo cha manganese ndikuwunika metallographic ya chinthu chomalizidwa komanso pambuyo pa chithandizo cha kutentha. Kapangidwe ka mankhwala wamba kamangosonyeza zizindikiro zakuthupi ndi zamankhwala. Kapangidwe ka makina sikangathe kukonzedwa kuti kafotokoze kukana kwake kukana. Nthawi zambiri, ndi chizindikiro choyamba cha kuuma chomwe chingatchulidwe.
Kuchiza kutentha ndi gawo lina lofunika kwambiri kuti zitsimikizidwe kuti zinthuzo ndi zolimba komanso zapamwamba. Kapangidwe ka chipinda chophwanyira chimakhudza kwambiri momwe chipangizo chophwanyira chimagwirira ntchito komanso nthawi yomwe zida zophwanyira zimagwirira ntchito.
Ngati muli ndi mafunso, chonde ndifunseni mu ndemanga, kapena nditumizireni uthenga wachinsinsi.
