Funsani

Annealing ndi njira yochizira kutentha kwa mapaipi osapanga dzimbiri.Cholinga chake ndikuchotsa kupsinjika kotsalira, kukhazikika miyeso, ndikuchepetsa chizolowezi cha deformation ndi kusweka.

Kodi kulumikiza chitoliro cha chitsulo chosapanga dzimbiri cha 2205 ndi chiyani?

Ndi chitoliro chopangidwa ndi ntchito yozizira, mpweya wa carbide, kuwonongeka kwa lattice, ndi mawonekedwe osagwirizana ndi kapangidwe kake kumapangitsa kuti kukana kwa dzimbiri kuchepe.Panthawi imeneyi, chithandizo cha annealing (kapena chithandizo chamankhwala) chikufunika.

Chifukwa chiyani chitoliro cha chitsulo chosapanga dzimbiri cha 2205 chimalumikizidwa?

Chepetsani kuuma kwachitsulo ndikuwongolera pulasitiki kuti muthandizire kudula ndi kuzizira kozizira

Yenga mbewu, homogenize zitsulo kapangidwe ndi kapangidwe, kusintha zitsulo katundu kapena kukonzekera wotsatira kutentha mankhwala

Chotsani kupsinjika kotsalira kwamkati muzitsulo kuti mupewe kupindika ndi kusweka.

2205 chitsulo chosapanga dzimbiri chubu annealing ndondomeko

Popanga, njira ya annealing imagwiritsidwa ntchito kwambiri.Malinga ndi zolinga zosiyanasiyana za annealing zomwe zimafunidwa ndi chogwiritsira ntchito, pali njira zosiyanasiyana zoyankhira, zomwe zimagwiritsidwa ntchito kawirikawiri ndi kuchepetsa kupsinjika maganizo, kutsegula kwathunthu ndi spheroidizing annealing.

Kuchepetsa kupsinjika maganizo.Chida chodziwika bwino chomangira machubu achitsulo chosapanga dzimbiri ndi ng'anjo yoyaka mosalekeza yomangira machubu achitsulo chosapanga dzimbiri, yomwe ndi ng'anjo yamoto yoyaka.Gwero la gasi loteteza limatenga ng'anjo yowola ya ammonia ndipo lili ndi chipangizo choyeretsera mpweya. Hangao Tech (SEKO Machinery) yasintha mawonekedwe a ng'anjo ya muffle, kuchotsa njira yotumizira lamba wa ma mesh ndikuyika m'malo mwake ndikupitilira mzere umodzi wa chubu.Zipangizozi zimakhala ndi mphamvu zowongolera, kupulumutsa mphamvu modabwitsa, kukonza bwino, ndi zina. Malo otentha a mzere wonse amatengera kuwongolera kutentha kwa PID.Mapaipi achitsulo osapanga dzimbiri amatenthedwa kudzera kutentha kuteteza zosapanga dzimbiri chitoliro chowala annealing ng'anjo mukusintha kwathu kumachepetsa ndikuwonetsetsa kuti mapaipiwo ndi ozungulira.

Zingwe zachitsulo zosapanga dzimbiri zimakonzedwa mofanana pachodyeramo, zimatumizidwa ku ng'anjo yowotchera kudzera pa lamba wotumizira, zimatenthedwa mpaka 1050-1080 ℃ motetezedwa ndi mpweya wowongolera, ndikusungidwa kwakanthawi kochepa, ma carbides onse amatha. Zisungunuke m'ng'anjo yotentha.Mu mawonekedwe a austenite, ndiyeno atakhazikika mwachangu mpaka pansi pa 350 ° C, yankho lolimba la supersaturated, ndiye kuti, mawonekedwe a unidirectional austenite, atha kupezeka.

Zoletsedwa kwathunthu.Amagwiritsidwa ntchito kuyeretsa mawonekedwe otenthedwa kwambiri okhala ndi zida zosauka zamakina pambuyo poponyera, kupanga ndi kuwotcherera kwachitsulo chapakati ndi chochepa cha carbon.Kutenthetsa workpiece kutentha kwa 30-50 ° C pamwamba pa kutentha komwe ferrite yonse imasandulika kukhala austenite, gwirani kwa kanthawi, kenako pang'onopang'ono muzizizira ndi ng'anjo.Panthawi yozizira, austenite imasinthanso, zomwe zingapangitse chitsulo kukhala chochepa kwambiri..

Spheroidizing Annealing.Amagwiritsidwa ntchito kuchepetsa kuuma kwakukulu kwa chitsulo chachitsulo ndi zitsulo zobereka pambuyo popanga.Chogwiritsira ntchito chimatenthedwa mpaka 20-40 ° C pamwamba pa kutentha komwe chitsulo chimayamba kupanga austenite, ndiyeno pang'onopang'ono chimakhazikika pambuyo posungira kutentha.Panthawi yozizira, lamellar cementite mu pearlite imakhala yozungulira, motero kuchepetsa kuuma.
