Nkhungu ndi chida chofunikira chothandizira kuzindikira luso lazopangapanga pakupanga, ndipo m'zaka zaposachedwa, lakhala likugwiritsidwa ntchito kwambiri popanga mafakitale amakono.Malinga ndi momwe amagwiritsidwira ntchito, ubwino wa nkhungu makamaka umadalira kusankha kwa zinthu za nkhungu ndi njira yochizira kutentha. Malinga ndi zikhalidwe za ntchito, nkhungu anawagawa ozizira kupanga nkhungu, ofunda forging nkhungu, otentha forging nkhungu, pulasitiki kupanga nkhungu ndi kuponyera nkhungu, etc. Nkhaniyi makamaka ikukhudza kusankha zinthu ndi kupanga ndondomeko otentha forging nkhungu.

1. Malamulo osankhidwa azinthu ndi chithandizo cha kutentha zofunikira zaukadaulo wamafuta otentha amafa：

Kupyolera mu kusanthula wamba kulephera mawonekedwe a otentha forging kufa, zikhoza kuoneka kuti kufa ayenera kuganiziridwa mu ndondomeko kusankha zinthu ndi.kutentha kwamphamvu,kuumitsa-kuthekera, mphamvu ndi kulimba, kutentha kutopa ntchitondi zina zotero. Kuchokera pakuwona chithandizo cha kutentha, ndikofunikira kulingalira kukana kuvala, decarburization pamwamba, kuuma, etc.

Thermal rigidity,amadziwikanso kuti red rigidity, amatanthauza nkhungu pamalo otentha kwambiri kuti asunge bata la bungwe ndi magwiridwe antchito, ndikutha kukana kufewetsa.Luso limeneli makamaka zimadalira mankhwala zikuchokera zinthu palokha ndi ndondomeko kutentha mankhwala. Nthawi zambiri, zitsulo zokhala ndi malo osungunuka kwambiri monga V, W, Co, Nb, Mo komanso zosavuta kupanga zinthu zambiri za carbide zimakhala zolimba pakutentha.

Mphamvu ndi kulimbazimaganiziridwa makamaka molingana ndi mphamvu ya nkhungu, kukula kwa mbewu zachitsulo, mawonekedwe, kugawa, kukula, kuchuluka kwa carbide ndi zomwe zili zotsalira za austenite zidzakhudza mphamvu ndi kulimba kwa nkhungu.Zinthu izi makamaka zimadalira kapangidwe ka chitsulo, momwe bungwe likuyendera komanso kagwiritsidwe ntchito koyenera kakuchiritsa kutentha.

Kuuma - kuthekeraamatanthauza kuuma osiyanasiyana zomwe zingatheke pambuyo pozimitsa zinthuzo, zomwe zimagwirizana mwachindunji ndi mpweya wa carbon. Zachidziwikire, pali zinthu zambiri zomwe zimakhudza moyo wamafa otentha, ndipo zida ziyenera kusankhidwa molingana ndi momwe zimagwiritsidwira ntchito pamoto wonyezimira.

2. Hot forging kufa processing luso：

Choyamba, bkukwera, kugwa ndispheroidizing annealing chithandizo:Zinthu za nkhungu zomwe zimaperekedwa ndi fakitale yachitsulo zimakhala makamaka ngati mipiringidzo kapena ma billets opangira, ndipo ma carbides mu bungwe lamkati amagawidwa m'malo ochezera pamalire ambewu. Ngati zipangizo za nkhungu zomwe zili mu mawonekedwewa sizikukonzedwanso, ming'alu imakhala yosavuta kuyambitsa ndi kufalikira pamphepete mwa malire a tirigu panthawi yomanga, kuchepetsa kubereka kwa nkhungu ndipo pamapeto pake kumachepetsa moyo wautumiki wa nkhungu.Kupyolera mu mankhwala opangira ndi spheroidizing annealing, carbide yaying'ono, yunifolomu ndi yobalalika imatha kupangidwa, mawonekedwe a mkati mwa nkhungu amasintha, ndipo zochitika zowonongeka zomwe zimachitika chifukwa cha kupsinjika kwa m'deralo mu ndondomeko ya kutentha zimapewedwa, ndipo moyo wautumiki wa nkhungu ndi bwino.

Chachiwiri, fkulandira chithandizo: Konzani kudula pamaso kutentha mankhwala, cholinga chachikulu chomwe ndi kupewa kupanga kupsinjika kwamphamvu pamwamba pa nkhungu panthawi yokonza ndikuchepetsa kutopa kwa nkhungu.Electrical kugunda processing ndi zinthu kusungunuka processing ndondomeko. Pambuyo pokonza mphamvu yamagetsi, chingwe chosungunuka ndi kutentha kwa kutentha kumapangidwa mosavuta pamwamba pa nkhungu, zomwe zimakhudzana ndi kuuma ndi kuvala kukana kwa nkhungu pamwamba. Pofuna kuchepetsa kupanikizika kwapang'onopang'ono komwe kumapangidwa pamwamba pa nkhungu pambuyo pa chithandizo cha kutentha, magetsi oyendetsa magetsi sagwiritsidwanso ntchito pambuyo pomaliza kutentha kwa kutentha, koma kuchepetsa ndalama zothandizira.Kapena ntchito njira akupera ndi kupukuta pambuyo pokonza kuchepetsa zotsatira pa wosanjikiza pamwamba processing kupewa kudula, makamaka magetsi zimachitika processing kuti nkhungu padziko kuwonongeka ndi zimakhudza moyo wa nkhungu.

Chachitatu, chithandizo cha kutentha:Tekinoloje yoyenera yogwiritsira ntchito iyenera kugwiritsidwa ntchito kuchepetsa kusinthika kwa nkhungu mu njira yochizira kutentha, monga kugwiritsa ntchito njira zotenthetsera zamitundu yambiri, zomwe zingalepheretse nkhungu kuti isatenthedwe. Pa nthawi yomweyo, njira kutentha mankhwala ayenera kupewa evaporation wa zinthu alloying, ndipo mkati kololeka osiyanasiyana zinthu kuumitsa luso, mpweya quenching luso ndi vakuyumu kutentha mankhwala ayenera kugwiritsidwa ntchito mmene ndingathere kuchepetsa kutentha kutentha mapindikidwe ndi kupewa kuwonjezeka kwa malipiro a processing pambuyo pa ulalo wa chithandizo cha kutentha, zomwe zimapangitsa kutentha kwapamwamba komanso kukhudza moyo wautumiki wa nkhungu.

Nizi, sotentha kuphulika, akupera, kupukuta mankhwala:pambuyo quenching ndi tempering ndondomeko, pamaso kutentha mankhwala, kuwombera peening ayenera kuchitidwa kupanga compressive maganizo wosanjikiza pamwamba pa kufa, kuti kusintha padziko kumakokedwa nkhawa boma la kufa pambuyo quenching ndi tempering mankhwala;mankhwala nkhungu kupukuta angathenso kuthetsa zofooka za nkhungu processing pamwamba ndi kusintha moyo utumiki.

Ndiye,Nayitrogeni wa ion: in pofuna kupititsa patsogolo kukana kutopa ndi kuvala kukana nkhungu, ndi bwino kugwiritsa ntchito N2 ndikupewa NH3, chifukwa H + mu NH3 imakhala ndi mphamvu ya hydrogen embrittlement pa nkhungu.Tiyenera kuzindikira kuti kutentha kwakuya kwa nayitrogeni kuyenera kukhala kochepa kuposa kutentha kwa kutentha pambuyo pozimitsa, kuti tipewe kuchepetsa kuuma kwa nkhungu, zomwe zimapangitsa kuti nkhunguyo isawonongeke..

Pomaliza, cchithandizo cha ryogenic: tiye mfundo ya cryogenic chithandizo ndi kuchepetsa otsalira austenite kupanga compressive kupsyinjika pamwamba pa nkhungu kusintha kuuma ndi pamwamba kuvala kukana nkhungu.Koma muyenera kukhala otetezeka. Zambiri za chithandizo cha cryogenic: nkhungu (kutentha kwa chipinda) - nayitrogeni wamadzimadzi (-196) "C / 2 maola - kubwerera kwachilengedwe ku kutentha kwa 160-170C / maola 4 opanda kuzirala.

Zonsezi, kupanga fakitale yotentha si ntchito yophweka, pali zambiri zoti mumvetsere komanso malamulo ambiri oti muwazindikire ndikutsatiridwa, ndikuyembekeza kuti zomwe zili pamwambazi zingakuthandizeni pamlingo wina. Takulandirani kusiya mafunso ndi malingaliro anu pansipa. ZZBETTER monga katswiri ndi luso kampani, ifenso opangidwa ambiri tungsten carbide otentha forging amafa ndi zinthu zina WC, kotero lemberani ife ngati muli ndi kufunsa kulikonse komanso.
