Kutanga, kushandiswa kweiyo carburizing agent muchoto carburizing nzira

1. Carbon, sechimwe chezvinhu zvakakosha musimbi yakakandwa, inonyanya kuoma kugadzirisa kupfuura zvimwe zvinhu.Nekuti kabhoni yakanyanya kuderera kupfuura simbi yemvura, kugona kunyura kuchave kwakadzikira pasina kuzungunuka kwakasimba.Kazhinji mu batching, kabhoni zvinoenderana nepamusoro pemuganho wezvido zvehurongwa, uye funga nezve kunyungudutswa kwekabhoni inopisa muripo, saka mirira kusvika simbi ichaja yajeka, huwandu hwekabhoni huri muhurongwa hwekuita, kunyangwe zvishoma kupfuura iyo yepamusoro. muganhu unogonawo kushandiswa kuwedzera zvishoma zve (zvakachena, zvakaoma) zvimedu zviri nyore kuunza pasi, muchoto chemagetsi kunyunguduka kabhoni pane carburizing operation iri nyore zvikuru.

2. Kudyisa kutevedzana

Danho 1: Kutanga kuisa imwe mari yekudzorera (kana kusara shoma shoma yesimbi yemvura) pazasi pechoto, kuitira kuti zvinhu zvitsva zvinyudzwe musimbi yemvura, kuderedza oxidation.

Danho rechipiri: Wedzera zvimedu zvesimbi kutanga, wobva wawedzera carburizing agent.Panguva ino, nzvimbo yekunyunguduka yesimbi yemvura yakaderera, iyo inogona kukurumidza kunyungudutswa kuti ivandudze kureba kweyero yemvura, kuitira kuti iyo carburizing agent inopinda musimbi yemvura.Iko kuwiriranisa kwe carburizing uye kunyunguduka kwesimbi hakuwedzere nguva yekunyungudika uye kunopedza simba shoma.Nekuda kwekudzikisa huwandu hweFeO neC hwakakwira kupfuura iyo yeSi neMn, kurasikirwa kwekupisa kweSi neMn kunogona kudzikiswa nekuwedzera carburizer pane yakaderera tembiricha.Edza kushandisa mabhegi ekurongedzerwa ane carburizing agent muchoto chemagetsi, usashandise spade pinch muchoto chemagetsi, kuitira kudzivirira zvimedu zvakanaka zvinoyamwa nemuunganidzi guruva.

Danho rechitatu: Zvimedu zvakanyungudutswa zvishoma uye mari yekudzorera inowedzerwa.Kuona kuti iyo carburizing agent yakanyungudutswa isati yanyungudutswa, panguva ino, high-power electric furnace (> 600kW/t) inonyanya kukosha nekuti nguva inodiwa yekunyungudutsa zvinhu inogona kunge iri shoma pane iyo nguva inodiwa yekunyura. iyo carburizer.Panguva imwecheteyo, basa rinokurudzira revira remagetsi rinofanira kushandiswa kusvika pamwero mukuru mukugadzirisa kutorwa kweagent carburizing.

Danho rechina: Kana chiyero chekudzoreredza che carburizing agent uye kutonga kwekabhoni yemukati meiron iron zvine chokwadi, iyo carburizing agent inogona kuwedzerwa nezvimedu kamwe.Kana isina chokwadi inogona kusiya 5% ~ 10% ye carburizing agent kuti ibatane kaviri.Iyo yechipiri yekuwedzera ye carburizing agent ndeye kukwenenzvera-tuning kabhoni (kana yekuwedzera yakapiswa kabhoni), inofanirwa kuwedzerwa mushure meiyo liquefier yesimbi, isati yajoinha iyo yemvura simbi pamusoro slag raking yakachena, nepazvinobvira kudzivirira carburizing mumiriri anopinda mu slag, uyezve. high-simba magetsi uchishandisa choto chemagetsi chinobvongodza basa rekuvandudza chiyero chekunyura.

Nhanho yechishanu: Wedzera ferrosilicon uye mamwe alloys, sampuli yekuongorora, gadzirisa kuumbwa, kunze kwevheni.Dzivisa kuchengeta simbi yemvura pakupisa kwepamusoro kwenguva yakareba.Kuchengetwa kwenguva refu kwesimbi yemvura pakupisa kwepamusoro (kunyanya kuvharidzira kwenguva refu pamusoro pe1450 ℃) iri nyore kutungamira kune oxidation yekabhoni, kuwedzera kwesilicon yemukati (silicon dioxide yakaderedzwa) uye kurasikirwa kwekristaro nuclei musimbi yemvura. .

Chechipiri, kushandiswa kwecarburizing agent mupakeji carburizing nzira

Kana zvichidikanwa kuvharisa mupakeji, saizi ye100 ~ 300 chinangwa carburizing agent inogona kuiswa pazasi pepakeji, uye tembiricha yepamusoro yemvura simbi inonyururwa zvakananga kune carburizing agent (kana kuwedzerwa nesimbi yemvura. kuyerera), uye simbi inonyandurwa zvizere mushure mekupera uye kutorwa kwekabhoni.Mhedzisiro yecarburizing mupakeji haina kunaka senge iri muchoto, uye mwero wekunyura wakaoma kudzora.Zvisinei nekushandiswa kweiyo carburizing agent kana carburizing nzira inofanirwa kutariswa kuburikidza neyakagadzirwa bvunzo carburizing process uye absorption rate process kana yatemerwa, usaite nyore kutsiva rudzi rwe carburizing agent uye mabviro, kana iwe uchida kuchichinja inofanira kupasa ongororo yekugadzira. zvakare.
