Zvikonzero nei kuoma kwe induction yakaoma zvikamu hazvienderane nezvinodiwa zvehunyanzvi

1. Kudzima tembiricha hakuna kukwana

Ndiko kuti, kupisa hakuna kukwana uye iyo austenitizing tembiricha inodiwa haina kusvika. Kune yepakati kabhoni structural simbi, pane isina kunyungudutswa ferrite mu austenite, uye kune isina kunyungudika ferrite mune inodzimwa chimiro kunze kwemartensite, uye iyo yakadzima pamusoro peiyo workpiece inowanzova yebhuruu. Iyo inogona zvakare kuoneka kubva pakuonekwa kweiyo induction yakaomeswa zvikamu izvo zvakajairwa kudzimwa nzvimbo ndeye beige, uye yakanyanyisa kupisa ichena.

2. Kutonhora kusina kukwana

Ndiko kuti, mwero wekutonhora wakaderera pane yakakosha kutonhora mwero. Muchigadziro chakadzimwa, kunze kwechikamu chemartensite, kunewo tortenite, uye iyo yakawanda yakawanda ye tortenite, yakaderera kuoma. Zvinowanzoitika kana kusangana kweiyo quenching medium, tembiricha, kudzvanywa kunoshanduka uye gomba rejekiseni remvura rakavharwa.

3. Self-tempering tembiricha yakanyanya

Dambudziko rekunyanyisa kudziya tembiricha rinoitika mukudzima kweshaft scanning, inowanzoitika panguva yekudzima shaft yakachinjika kana kutsika shaft yakatwasuka kudzima. Kana hupamhi hwejeti yemvura ipfupi, nzvimbo yekupisa inokurumidza kupfuura iyo jet yemvura uye haitonhodze chikamu chekudzima zvakakwana, uye kuyerera kwemvura kunovharwa nematanho (chikamu chikuru chedhayamita chiri pamusoro, chikamu chidiki chedhayamita. iri pasi), uye chikamu chakadzimwa hachigoni kuramba chichitonhodzwa. Nekuda kweizvozvo, kutaridzika kwekudziya tembiricha kunowanzo kucherechedzwa uye kunoonekwa pane yakadzima.

4. Soft spot kana spiral black belt

Nzvimbo dzakapfava nemabhuroko panzvimbo yakadzimwa dzinowanzova nhema, uye bhandi dema rinotenderera rinowanzoitika chikanganiso chekuongorora zvikamu zvakadzimwa. Iri bhendi dema rinodaidzwawo kuti bhendi rakapfava, uye rinowanzova chimiro che tortite. Mhinduro ndeyekupfapfaidza mvura yakaenzana, uye kuwedzera kumhanya kwekutenderera kweiyo workpiece kunogonawo kuderedza kukwirira kwebhandi dema, asi chinonyanya kukosha ndechekuti chimiro chemvura yekupfapfaidza chinofanirwa kuita kuti nzvimbo yekudziya itonhorere zvakaenzana. Makomba ejeti akavharika anowanzova chimwe chezvikonzero zvemavara akapfava.

5. Kufurira kwezvinhu zvemakemikari

Kudzikiswa kwekuumbwa kwezvinhu, kunyanya iyo kabhoni yemukati, chimwe chezvikonzero zvekudzikisa kuoma. Kana zvichidikanwa, iyo yakasarudzwa kabhoni yemukati inogona kushandiswa kune zvakakosha zvikamu, kuitira kuti iyo yepamusoro uye yakaderera miganho yew (C) inogona kuderedzwa kusvika mukati me0.05%.

6. Kugadzirira kupisa kurapwa

Shanduko mukudzima uye kudzikamisa maitiro, uye ganda dema rezvinhu zvakakungurutswa rinoramba riri pamusoro pekudzima zvakare zvikonzero nei kuoma kweiyo induction yakaomeswa zvikamu zvisingaite zvinodiwa zvehunyanzvi.

7. Surface decarburization uye decarbonization

Inowanzoitika pamusoro pezvinhu zvinotonhora-zvinodhonzwa. Naizvozvo, mushure mekudzima mbariro idzi, dhizaini rekunze rinogona kugadzika ne 0.5mm kusati kwaoma. Kana kuomarara kwepamusoro kwakadzikira, kuomarara kwemukati kwakakwirira kudarika pamusoro, zvichiratidza kuti pane kabhoni-yakapera kana decarburized layer. (kunze kweakakosha majeometri akadai secam lobes, magiya epamusoro).

8. Ribhoni primitive tissue

Iyo yakasungirirwa chimiro muchimiro chepakutanga chechikamu chakadzimwa chichatungamira kusakwana kwekuoma mushure mekudzima. Pane ferrite isina kunyungudutswa mubhanhire yakagadzirwa, iyo isingagoni kunyungudutswa panguva ye austenitization process, uye kuoma mushure mekudzima kunofanira kunge kusina kukwana, uye bhanhire rakasungirirwa rakaoma kubvisa kunyange kana kupisa kwekushisa kuchiwedzerwa.
