M’pofunikanso kusankha quenching kutentha kwa zitsulo bala quenching ndi tempering mankhwala mzere
Pafupipafupi zida zotentha Nthawi zambiri amagwiritsa ntchito sikani kuzimitsa pamene Kutentha malo workpiece ndi lalikulu ndi magetsi ndi ochepa. Panthawiyi, malo owerengetsera otentha A amatanthauza malo ozungulira ndi inductor. Ndi mphamvu yofananira yamagetsi, gwero lamagetsi lofunikira ndilochepa, ndipo ndalama zogulira zida ndizochepa, zomwe ndizoyenera kupanga magulu ang’onoang’ono.
Chitsulo chozimitsa ndi kutenthetsa zida zochizira kutentha zimakhala ndi kutentha kwina kozimitsira pagawo lililonse lachitsulo. Pokhapokha ndi kutentha ndi kuzimitsa mkati mwa kutentha kumeneku kungapangidwe ndi ntchito yokhutiritsa. Pamene kutentha kwa kutentha kumakhala kosalekeza, ngati kutentha kozimitsa komwe kumasankhidwa kumakhala kochepa kuposa kutentha koyenera, chifukwa kusintha kwa gawo sikuli kokwanira, mawonekedwe otentha ndi austenite kuphatikiza ferrite, kapena austenite kuphatikiza spherite, kuzimitsidwa Mapangidwewo ndi martensite kuphatikiza ferrite kapena martensite. kuphatikiza ngale, ndipo kuuma kudzachepa. Ngati quenching Kutentha kutentha ndi apamwamba kuposa mulingo woyenera kwambiri kutentha, otentha austenite njere adzakula, ndipo zotsatira analandira pambuyo quenching. Pakati singano kapena wandiweyani singano martensite, ngati ndi mkulu mpweya zitsulo, padzakhala anapitiriza austenite, amene kuchepetsa kuuma padziko.
Mu kupanga kwenikweni, ngati mulingo woyenera kwambiri quenching kutentha osiyanasiyana kalasi zitsulo anatsimikiza, koma chifukwa Kutentha mlingo (ndiko kuti, mphamvu yeniyeni pamene mbali ndi usavutike mtima) ndi wamkulu kuposa kapena wocheperako lolingana Kutentha mlingo, zachabechabe kapena osafunika. kuzimitsa zidzachitikanso Organization, ngati Kutentha mlingo wa kupatsidwa ulemu Kutentha zida ndi zosakwana lolingana Kutentha mlingo, workpiece adzakhala mkangano kwa anatsimikiza quenching kutentha, ndi dongosolo superheated adzakhala analandira pambuyo quenching. Ngati mathamangitsidwe ndi wamkulu kuposa lolingana Kutentha mlingo, workpiece adzakhala mkangano kwa anatsimikiza quenching kutentha, pambuyo kuzimitsa A kuzimitsidwa dongosolo ndi Kutentha kokwanira adzakhala analandira. Choncho, posankha kutentha kozimitsira kwazitsulo zachitsulo kuzimitsa ndi kutenthetsa mzere wa mankhwala, osati zolemba zokhazokha zakuthupi ndi mapangidwe oyambirira ayenera kuganiziridwa, koma mphamvu ya kutentha kwachangu iyeneranso kuganiziridwa.
