Ukucima kunye nokunciphisa ii-crankshafts

Inkqubo yokucima kunye nenjongo
I-workpiece ishushu kwiqondo lobushushu le-austenitizing ixesha elithile kwaye lipholile kwizinga elikhulu kunezinga lokupholisa elibalulekileyo lokufumana inkqubo yonyango lobushushu lwesakhiwo se-martensite.
Ukuphucula ubunzima obuphezulu kunye nokugqoka ukuchasana kwe-workpiece
Inkqubo yobushushu obuphantsi kunye nenjongo
Inkqubo yonyango lokushisa apho intsimbi ecinyiweyo ishushu kwi-250 ° C. kwaye emva koko ipholile.
Ukuze kugcinwe ubunzima obuphezulu kunye nokumelana nokuxhatshazwa kwe-workpiece ecinyiweyo, ukunciphisa uxinzelelo olushiyekileyo kunye nokuqina ngexesha lokucima.
Indlela yokwahlula phakathi kwe-crankshaft ecinyiweyo kunye engacinywanga?
I-ayini idibana neekhemikhali kunye neoksijini esemoyeni kumaqondo obushushu aphezulu ukuze ivelise i-iron trioxide emnyama. Oku kwahlukile kwinto esiyibiza ngokuba ngumhlwa. Into esiqhele ukuyithetha ngomhlwa kukuba i-iron idibana neoksijini, amanzi, kunye nezinye izinto ezisemoyeni kwiqondo lobushushu begumbi ukuze zenze (inxalenye eyintloko yomhlwa) i-iron oxide, ebomvu.
Iayini ifudunyezwa kwioksijini:
3Fe + 2O2 === Ukufudumeza ==== Fe3O4
Iayini iyarusa emoyeni:
i-crankshaft engacinywanga
i-crankshaft ecinyiweyo
