Zopangiramukukonza ndondomeko, Kutentha mankhwala ndi ulalo wofunika kwambiri, kutentha mankhwala pafupifupi annealing, normalizing, quenching ndi tempering njira zinayi zofunika, amene amadziwika kuti zitsulo kutentha mankhwala a "chinai moto".
imodzi, chithandizo chachitsulo chachitsulo chamoto - annealing:
1, annealing ndi kutenthetsa workpiece ndi kutentha koyenera, malinga ndi zinthu ndi workpiece kukula ntchito osiyana akugwira nthawi, ndiyeno pang'onopang'ono kuzirala, cholinga chake ndi kupanga zitsulo mkati bungwe kufika kapena kuyandikira boma mgwirizano, kupeza ntchito yabwino ya ndondomeko ndi ntchito, kapena kuzimitsa kwina kwa kukonzekera minofu.
2, cholinga cha annealing:
① Kupititsa patsogolo kapena kuthetsa chitsulo pakuponya, kupangira, kugudubuza ndi kuwotcherera komwe kumachitika chifukwa cha zolakwika zosiyanasiyana zamagulu ndi kupsinjika kotsalira, kuteteza kusinthika kwa chogwirira ntchito, kusweka.
② Pewani chogwirira ntchito podula.
③ Yenga mbewu ndikuwongolera kapangidwe kake kuti muwongolere zida zamakina a workpiece. (4) Konzekerani chithandizo chomaliza cha kutentha (kuzimitsa, kutentha).
Awiri, zitsulo kutentha chithandizo chachiwiri moto - normalizing:
1, normalizing ndi kutenthetsa workpiece kutentha koyenera pambuyo kuzirala mu mlengalenga, zotsatira za normalizing ndi ofanana annealing, koma kapangidwe ndi bwino, nthawi zambiri ntchito kusintha kudula ntchito zipangizo, komanso nthawi zina ntchito mbali zina. ndi zofunika otsika monga chomaliza kutentha mankhwala.
2, cholinga normalizing:
① Itha kuthetseratu kutentha kwakukulu kwa njere ndi mawonekedwe a mawidnell akuponyera, kupangira ndi kuwotcherera mbali, ndi zomangira zomangira muzinthu zopukutira; Kukonzekera kwambewu; Ndipo angagwiritsidwe ntchito ngati chisanadze kutentha mankhwala pamaso quenching.
② Ikhoza kuthetsa maukonde yachiwiri simenti, ndikuyenga pearlite, osati kusintha makina katundu, komanso yabwino tsogolo spheroidizing annealing.
③Simenti yaulere pamalire a tirigu imatha kuthetsedwa kuti ntchito yojambula ikhale yozama.
Chachitatu, chithandizo chachitsulo chachitsulo chachitatu chamoto - kuzimitsa:
1, kuzimitsa ndi kutenthetsa workpiece pambuyo kuteteza kutentha, m'madzi, mafuta kapena mchere zina inorganic, organic madzi njira ndi zina quenching sing'anga kuzirala mwamsanga. Pambuyo kuzimitsa, zitsulo zimakhala zolimba, koma nthawi yomweyo zimakhala zowonongeka.
2. Cholinga cha kuzimitsa:
① Sinthani makina azinthu zachitsulo kapena magawo. Mwachitsanzo: kusintha kuuma ndi kuvala kukana kwa zida, mayendedwe, etc., kusintha malire zotanuka akasupe, kukonza mabuku katundu mbali kutsinde, etc.
②, kusintha zinthu zakuthupi kapena mankhwala achitsulo chapadera. Monga kuwongolera kukana kwa dzimbiri kwa chitsulo chosapanga dzimbiri, onjezerani maginito okhazikika achitsulo chachitsulo, etc.
Chachinayi, chithandizo cha kutentha kwachitsulo chachinayi chamoto - kutenthetsa:
1, kutentha pofuna kuchepetsa brittleness chitsulo, kuzimitsa zitsulo pa kutentha ena oyenera pamwamba kutentha firiji ndi pansi 710 ℃ kwa nthawi yaitali, ndiyeno kuzirala, ndondomeko amatchedwa tempering.
2, cholinga cha kuchepetsa:
①, kuchepetsa kupsinjika kwamkati ndikuchepetsa brittleness, pamakhala kupsinjika kwambiri komanso kupsinjika kwa magawo ozizimitsa, monga kusatentha kwanthawi yake nthawi zambiri kumatulutsa mapindikidwe komanso kusweka.
② Sinthani mawonekedwe a makina a workpiece. Pambuyo kuzimitsa, workpiece ndi mkulu kuuma ndi brittleness. Pofuna kukwaniritsa zofunikira zosiyanasiyana za ntchito zosiyanasiyana, kuuma, mphamvu, pulasitiki ndi kulimba kungasinthidwe ndi kutentha.
③, khazikitsani kukula kwa workpiece. Ndi kutentha, mawonekedwe a metallographic akhoza kukhazikika kuti atsimikizire kuti mapindikidwe sadzachitika m'tsogolomu.
④, sinthani magwiridwe antchito achitsulo cha aloyi.
