Kodi quenching kutentha osiyanasiyana a ng’anjo yamoto

Kodi kutentha kwa ng’anjo ya bogie ndi yotani? Nthawi zambiri, kutentha kwapakati kumakhala kocheperako kuyambira 20 mpaka 35 ° C.

1. Kugubuduza zitsulo zokhala ndi zitsulo pambuyo pa spheroidization ndi annealing zimakhala ndi ntchito yabwino yodula, yomwe ndi yofunika kwambiri popanga zitsulo zogudubuza pamzere wodzipangira;

2. Pambuyo spheroidizing akugubuduza kubala zitsulo, ng’anjo trolley ali mkulu kukhudzana kutopa mphamvu, kuvala kukana ndi toughness pambuyo quenching ndi otsika kutentha kutentha;

3. Pakugubuduza zitsulo zokhala ndi zitsulo popanda spheroidization, kutentha kozimitsa kumakhala kocheperako (20 ~ 35 ℃), koma pambuyo pa spheroidization, kutentha kozimitsa kumakulitsidwa mpaka 40 ~ 45 ℃, ndipo chizolowezi cha kutenthedwa ndi kupindika ndi kusweka panthawi yozimitsa ndi. kuchepetsedwa. . Kugudubuza zitsulo zokhala ndi spheroidizing annealing process point Kugudubuza kokhala ndi chitsulo kumatha kutengera kuzizira pang’onopang’ono spheroidizing kapena kutentha spheroidizing njira.

Nthawi zambiri amakhulupirira kuti mainchesi ozungulira a carbides pambuyo pa annealing ndi 0.4 mpaka 0.5 μm. Pamene chiŵerengero cha ozungulira carbides mu kapangidwe kuzimitsidwa ng’anjo trolley ndi 7 mpaka 8%, moyo wa anagubuduza kubala.

Pambuyo spheroidizing annealing, pamene m’dera chiŵerengero cha ozungulira carbides ndi pafupifupi 15%, kuti 7-8% ya ozungulira carbides kukhalabe pambuyo kuzimitsidwa mu ng’anjo muffle, kukula kwa ozungulira carbides pambuyo annealing ayenera mosamalitsa ankalamulira kuti izo. 0.4 ~ 0.5μm. Pachifukwa ichi, ng’anjo yokhazikika komanso yodalirika iyenera kugwiritsidwa ntchito popanga spheroidizing annealing.
