Ndi chitukuko chofulumira cha mafakitale amafuta aku China, kufunikira kwazitsulo zapamwamba kumakulirakulira, ndipo chitsulo chapamwamba chiyenera kuzimitsidwa, chifukwa chake kuphunzira kuzimitsa kwathunthu kwachitsulo ndikofunikira kwambiri. China Heavy Machinery Research Institute yapanga "kuviika quenching + kutsitsi mkati + kupota" ndi "kunja kwa shawa lamkati la ndege + sapota" njira ziwiri, ndi kafukufuku ndi chitukuko chokhudzana ndi mzere wozimitsa, ndikupeza zotsatira zabwino. Onse quenching ndondomeko ali ndi makhalidwe ake, shawa kunja mkati ndege kuzimitsa kupanga mzere ndi oyenera mafuta chitsime mipope, mafuta casing, kubowola chitoliro quenching, yabwino kwa wonse quenching woonda khoma zitsulo chubu; Kumizidwa kuzimitsa kupanga mzere ndi oyenera khoma makulidwe kuyerekeza Great wonse kuumitsa mkulu ntchito wandiweyani-mipanda chubu, ndipo mankhwala ake zimagwiritsa ntchito chitetezo dziko, mphamvu nyukiliya, mafuta ndi gasi ndi magalimoto mafakitale.

Kumiza kuzimitsa kupanga mzere
Zipangizo zozimitsa zapakhomo zomwe zimagwiritsidwa ntchito pano, pali zolakwika zina zamachubu zokhuthala, monga (1), kupindika kwa chitoliro chokhuthala chozimitsidwa mosavuta, kuwongoka, kuzunguliridwa kosauka, kumapangitsa kuti pakhale zovuta; (2) mkati ndi kunja chitoliro sangathe kuzimitsidwa, chifukwa Markov thupi okhutira ndi otsika, wosagwirizana kuuma; (3) kukwera mtengo kwa ntchito, kusatetezeka bwino. Poyankha zofooka izi, chipatala paokha kafukufuku ndi chitukuko, akanema wathunthu wa kupanga dziko loyamba ntchito "kumiza quenching + kuzungulira + utsi wamkati" quenching wa zitsulo chitoliro khoma makulidwe kuposa 20 mm kuchokera lonse kumizidwa quenching kuzimitsa quenching mzere kupanga. Njira yopangira ng'anjo ndi: zida zotenthetsera zitsulo zowuma → choyezera chofikira chokwera chokwera mozungulira mofulumizitsa njira kukanikiza chitoliro chachitsulo chothandizira → mozungulira chitoliro chonyamulira chokwera mozungulira kuyendetsa mtengo wachitsulo kumiza mwachangu m'madzi → mkati mwa kutsitsi. mphuno yolowera mkati mwa jekeseni wa chitoliro chachitsulo → kumapeto kozimitsa, mkati mwa malo opoperapo → za kukweza silinda idzakwera matabwa achitsulo → pindani kuti muyimitse kudyetsa chipangizo pa chipangizo chodyera ndi chipika-ndi-kutembenukira ku mizu ya madzi opanda kanthu. Chitoliro cha chitoliro → Madzi opanda kanthu amatanthawuza kukweza mbali imodzi ya chitoliro adakwezedwa kuphulika kwina kokakamira mpweya kuzimitsa madzi → madzi → chitoliro chonyamulira mkati mwa chitoliro pang'onopang'ono kupita ku zodzigudubuza → zitsulo zowumitsa. Izi kumiza kuzimitsa quenching wagawo kwa nthawi yoyamba ntchito "kumiza quenching + atembenuza + mkati kutsitsi" luso latsopano m'mimba mwake lalikulu, wandiweyani-mipanda chubu chonse kuzimitsidwa kuthetsa lalikulu m'mimba mwake wandiweyani-mipanda chitoliro mapindikidwe quenching, quenching wosagonjetsa luso mavuto; Tidapeza zotsatirazi zotsatirazi: (1) Chifukwa cha kuchuluka kwa chitoliro chamadzi, kusinthasintha kothamanga kwambiri, chithandizo chothandizira chamitundu yambiri, kotero kuti kuwongolera bwino kwachitsulo, zosakwana 2 mm / m, kumakwaniritsa zofunikira za mankhwala. (2) kugwiritsa ntchito kasinthasintha mkati mwa nozzle yopopera yam'manja, kuchepetsa chitoliro cha ovality mutu wothandiza chitoliro. (3) Ndi kusuntha kuzimitsa mkati quenching ndondomeko kusinthasintha, yunifolomu makina katundu zitsulo, pambuyo quenching martensite kutembenuka mlingo wa pa 90%, ngakhale 95%, kuuma ndi makulidwe malangizo a zonse kutalika zitsulo chitoliro zolakwa ≤ 3 HRC.

"Utsi + kunja shawa + mkati sapota" kuzimitsa njira.
Njirayi ndi yopyapyala khoma makulidwe a chitoliro. ng'anjo yachitsulo yowumitsidwa imatenthedwa mpaka pafupifupi 1000 ℃, chogudubuza chakudya kupita kumalo omwe tingayembekezere, chipangizo chodyera kukweza chitsulo ndikuchiyendetsa pang'onopang'ono kumatanthawuza mawilo ozungulira, kupanikizika komwe kumayikidwa pazitsulo zopopera kumangirira mofulumira kumatanthauza kukanikiza chitoliro, rotary pagalimoto amatanthauza mofulumira atembenuza mofulumizitsa zitsulo chitoliro, zitsulo chitoliro ili mwachindunji pamwamba padziko kunja kwa chubu kuthira kwa yunifolomu akunja chitoliro sprinkler, pamene kutsitsi njira anaika mu chitoliro mapeto a chitoliro khoma kwa kutsitsi mutu. Choncho malo amkati ndi akunja a chitoliro chachitsulo akhala akuzimitsa yunifolomu.
