Iyo graphitization maitiro esimbi yakakanda uye zvinhu zvinokanganisa graphitization yesimbi yakakanda

 1. Graphitization maitiro esimbi yakakandwa

    Iyo yekuumba maitiro e graphite mu cast iron inonzi graphitization maitiro. Iyo yakakosha maitiro eakaumbwa esimbi simbi ndiyo yekuumba maitiro e graphite mune yakakanda simbi. Naizvozvo, zvakakosha kuti unzwisise mamiriro uye zvinhu zvinokonzeresa kuita kwe graphitization kugona chimiro nehunhu hwesimbi yezvinhu.

    Zvinoenderana neiri mbiri dhayagiramu yeFe-C chiwanikwa, iyo graphitization maitiro esimbi yakakandwa inogona kuganhurwa muzvikamu zvitatu:

    Chikamu chekutanga chikamu chemvura hypoeutectic crystallization nhanho. Kusanganisira iyo yekristallis yakananga yeiyo yekutanga graphite kubva kune yakasviba chikamu cheiyo hypereutectic zvinoriumba uye chikamu chemvura cheeutectic zvinoriumba kuburitsa austenite pamwe ne graphite, graphite inoumbwa neyakaora yekutanga cementite uye eutectic cementite panguva yekupisa tembiricha annealing.

    Iyo yepakati danho idanho pakati eutectic shanduko uye hypoeutectoid shanduko. Kusanganisira iyo yekunaya yakananga yechipiri graphite kubva austenite uye iyo graphite inoumbwa nekuora kweyechipiri cementite mune ino tembiricha renji.

    Chikamu chechitatu, ndiko kuti, chikamu cheshanduko yemutengo wakazara. Kusanganisira iyo eutectoid graphite yakaumbwa panguva yeku-kupeta shanduko uye iyo graphite inoumbwa nekuora kweiyo eutectoid cementite panguva yekuwedzera.

2. Zvinhu zvinokanganisa graphitization yesimbi yakakandwa

    Maumbirwo esimbi simbi anoenderana nedanho re graphitization. Kuti uwane chimiro chinodiwa, chakakosha kudzora mwero we graphitization. Kudzidzira kwakaratidza kuti zvinhu zvakawanda zvakaita semakemikari akaumbwa nesimbi, iyo inotonhora mwero wemakristani esimbi, kupisa nekumira kwesimbi yakanyungudutswa, nezvimwewo, zvese zvinokanganisa graphitization uye microstructure yesimbi yakakandwa.

1. Iko kukanganisa kwemakemikari ekuumbwa

    Pakati peyakajairika C, Si, Mn, P, uye S mune simbi yakakandwa, C uye Si zvinhu zvinokurudzira zvakanyanya graphitization, uye S chinhu chinodzivirira zvakanyanya graphitization. Muchokwadi, iko kukanganisa kwechinhu chimwe nechimwe pa graphitization kugona kwesimbi yakakanda kwakanyanya kuomarara. Simba rayo rakanangana nezviri mukati mechinhu chimwe nechimwe pachacho uye kana chichipindirana nezvimwe zvinhu, zvakaita saTi, Zr, B, Ce, Mg, nezvimwewo, zvese zvinotadzisa graphitization, asi kana zvirimo zvakaderera zvakanyanya (seB, Ce <0.01%, T <0.08%), ivo vanoratidza mhedzisiro yekusimudzira graphitization.

2. Mhedzisiro yekutonhora mwero

    Kazhinji kutaura, kutonhora kweye castings kunowanzoita kunonoka, kunonyanya kufadza iko kuve crystallization uye shanduko zvinoenderana nehurumende dhizaini yeFe-G yakagadzikana system, uye yakazara graphitization; zvinopesana, zvinobatsira kuve nekristalllization uye shanduko maererano nemufananidzo wedunhu weFe-Fe3C metastable system. Pakupedzisira ndakawana iron chena. Kunyanya mu graphitization padanho reyutectoid, sezvo tembiricha iri shoma, mwero wekutonhora unowedzera, uye kupararira kwemaatomu kwakaoma, zvinowanzo kunetsa kufambisa zvizere graphitization padanho reeutectoid.

    Iyo inotonhorera mwero wesimbi yakakanda chinhu chakazara, chinoenderana nekudira tembiricha, iko kupisa kwekushisa kwezvinhu zvekuumba uye madziro mukobvu wekukanda. Uye kazhinji izvi zvinhu zvine zvazvinoita zvakafanana pamatanho maviri.

    Kuwedzera kwekudziya tembiricha kunogona kunonotsa kutonhora kweyekukanda, iyo inosimudzira zvese yekutanga nhanho ye graphitization uye yechipiri nhanho ye graphitization. Naizvozvo, kuwedzera kudurura tembiricha kunogona kupura girafu kune imwe nhanho, uye kunogona zvakare kuwedzera iyo eutectoid shanduko.

3. Mhedzisiro yekupisa uye yakanyanya tembiricha kumira kwesimbi yakakandwa

    Mukati meimwe tembiricha renji, kuwedzera kupisa kwekudziya kwesimbi yakanyunguduka uye kuwedzera iyo yakanyanya-tembiricha yakamira nguva ichaguma nekunatsiridzwa kweiyo graphite-yakavakirwa simbi musimbi yakakandwa uye kuwedzera simba resimbi yakakandwa. Kana iyo superheat ikawedzera kuwedzerwa, iyo nucleation kugona kwesimbi yakakanda inoderera, uye graphite morphology ichashatiswa, uye kunyangwe yemahara cementite ichaonekwa, iyo inoderedza simba, saka kune'critical tembiricha '. Iyo yakaoma tembiricha inowanzoenderana nemakemikari akaumbwa esimbi yakanyungudika uye inotonhora mwero wekukanda. Inowanzo davirwa kuti yakanyanya tembiricha tembiricha yakajairwa grey yakakanda simbi ingangoita 1500-1550 ℃, saka zvinogara zvichitarisirwa kuti iyo simbi yekukanda tembiricha yakakwira.

Ndokumbirawo uchengete kwainobva nekero yechinyorwa chino kuti iprote zvakare: Iyo graphitization maitiro esimbi yakakanda uye zvinhu zvinokanganisa graphitization yesimbi yakakanda

Minghe Kambani Inokanda Kambani dzakatsaurirwa kugadzira uye kupa mhando uye epamusoro kuita Kukanda Zvikamu (simbi kufa zvikamu zvekukanda mhando zvinonyanya kusanganisira Mutete-Wall Yakakanda Kukanda,Hot Chamber Die Kukanda,Cold Chamber Die Kukanda), Round Sevhisi (Die Kukanda Service,Cnc machine,Kugadzira Mould, Surface Kurapa) .Chero tsika yeAluminium kufa kukanda, magnesium kana Zamak / zinc kufa kukanda uye zvimwe zvinodiwa zvekukanda zvinogamuchirwa kuti utibate.
