1. Beryllium oxide:beryllium okusayidi sikuti amangotaya chitsulo chochuluka, komanso amachepetsa mawonekedwe a pamwamba pa forgings ndi moyo wautumiki wakutaya ufa.Ngati wapanikizidwa muzitsulo, ndiyezojambulaadzachotsedwa.Kulephera kuchotsa beryllium oxide kudzakhudza kutembenuka.
2. Decarburization:Decarburization imatanthawuza chodabwitsa kuti zonse kapena gawo la kaboni pamwamba pazitsulo zimatenthedwa.Decarburization imapangitsa pamwamba pa workpiece kuwoneka mawanga ofewa, kuchepetsa kuuma kwa pamwamba, kukana kuvala komanso kutopa.
3. Kutentha kwambiri ndi kutentha kwambiri:Kutentha amatanthauza zitsulo Kutentha kupitirira kololeka kutentha, kuti mbewu kukula coarse.Kutentha kwambiri si kothandiza kutentha kutentha, kotero kuti forgings kukhala Chimaona Chimaona ndi mawotchi katundu yafupika, koma akhoza kuthetsedwa ndi normalizing kapena annealing pambuyo.kupanga.Kuwotcha kwambiri kumatanthawuza kuchitika kwa ma oxides kapena kusungunuka pang'ono kwa zitsulo chifukwa cha nthawi yotentha ndi yayitali komanso kutentha kwambiri.Kutentha thupi sikungatheke.

4. Kupsinjika:chifukwa cha kusiyana pakati pa mkati ndi kunja kwa chitsulo, kuwonjezereka sikuli kofanana, ndipo kupanikizika kwamkati kumapangidwa, komwe kumatchedwa kutentha kwa kutentha.Kusintha kotsatizana kwa kapangidwe ka metallographic komwe kumachitika chifukwa cha kutentha kumayambitsanso kupsinjika, komwe kumatchedwa kupsinjika kwa microstructure.Izi zipangitsa workpiece mu Kuwotcha mng'alu, chifukwa workpiece pambuyo galimoto processing mng'alu ndi zidutswa.
5. Kuthyoka pakati:chilema ichi amawononga mankhwala zikuchokera ndi microstructure yunifolomu zitsulo, amachepetsa quenching kuuma ndi kuwonongeka makina katundu.Ngati kutentha kwa annealing ndikokwera kwambiri ndipo kumabweretsa gawo la graphite, sizingakhale zophweka kudula ndi kuzimitsa kutentha kwambiri ndi kupunduka.Koma ngati annealing kutentha kapena otsika kutentha, pearlite sangathe kumaliza kudalirana kwa mayiko, si abwino kudula ndi wotsatira kutentha mankhwala.
6. hard and brittle mesh carbide: zimafooketsa mphamvu yolumikizirana pakati pa zinthu za kristalo, zida zamakina zimayipitsitsa kwambiri, makamaka kulimba kwamphamvu kumachepetsedwa, koma kumatha kusinthidwa kapena kuthetsedwa ndi normalizing.Ngati pali banded carbide, zidzachititsa kuuma ndi dongosolo quenching ndi tempering osagwirizana, ndi zosavuta mapindikidwe, amenenso ndi chilema cha banded dongosolo la pearlite ndi ferrite pamodzi malangizo processing mapindikidwe.Panthawi imodzimodziyo, idzachepetsanso pulasitiki ndi kulimba kwazitsulo, kotero kuti kukula kwa makina sikuli kokhazikika, kuvala kwachangu kwa zida.
