Inoita sei kudonhedzwa kunyorera vira kuita simbi?

Yekutanga gadziriro yekugadzira simbi muchoto chekunyungudutsa induction:

1. Paunenge uchigadzirira kugadzira simbi, basa rekutanga rekuongorora harifaniri kuregererwa. Iwe unofanirwa kutanga wanzwisisa mamiriro eiyo lining yechoto, kana maturusi ekugadzira akazara, uye kuti induction inonyungudutsa choto pani yakajairika.

2. Zvose zvigadziko zviviri zvevira zvakagadzirirwa, uye zvigadzirwa zvinodiwa zvakadai seferrosilicon, medium manganese, synthetic slag, mumiririri wekuchengetedza kupisa, nezvimwewo zvinofanira kugadzirirwa panzvimbo uye kuiswa pakati pevira.

3. Chigadzirwa chesimbi chinofanira kunge chiri panzvimbo, uye choto haigoni kutangwa kana simbi isina kunyatsogadzirirwa.

4. Chenjerera kune insulation rubber bedding ye induction melting furnace, uye inorambidzwa zvachose kusiya chero mapeji.

Yechipiri ndeyekutarisisa kana iyo induction inonyungudutsa simbi yekugadzira simbi inopinda muchikamu chekugadzira:

1. Iyo nyowani lining lining ichave yakabikwa mukuomerera zvinoenderana nezvinodiwa zveiyo nyowani bheka kubheka maitiro, uye nguva yekubheka inofanira kuve yakakura kupfuura maawa maviri.

2. Kutanga wedzera kapu diki yekusveta kuchoto kuti udzivirire jira revira. Hazvibvumirwi kuwedzera zvakananga zvidimbu zvakakura zvezvinhu muchoto chisina chinhu, uye wozoshandura magetsi. Panguva ino, mushandi wepamberi wechoto anofanira kuwedzera zvinhu zviduku zvakapararira zvakapoteredza choto muchoto munguva, uye zvinorambidzwa zvachose kudonha. Iyo chitofu chepamusoro uye silicon simbi sheet punch inongotenderwa kushandiswa panguva yehovhoni, uye haibvumidzwe kushandiswa panguva yakasara yenguva.

3. Iyo dhisiki hoist inosimudza zvinhu ichiisa pachitofu kubva mustockyard, uye vashandi vepamberi vanoronga zvimedu zvesimbi. Izvo zvakarongwa zvinopisa uye zvinhu zvinoputika zvinoiswa zvakananga mubhokisi rekuunganidza rakakosha uye zvakanyoreswa uye zvinosimbiswa nekuchengetedzwa kwechitofu.

4. Bhokisi rakakosha rekuunganidza rezvinhu zvinopisa uye zvinoputika rinoiswa pakati pemaseti maviri emabhesi echoto, uye hapana anogona kuifambisa paanoda.

5. Kudyisa pamberi pechoto kunonyanya kushandiswa nemaoko. Mushure mokunge tsvina yechitofu yakanyatsorongedzwa, kureba kwezvinhu zvishoma kudarika 400mm, uye zvinhu zvakanyatsosarudzwa nemutungamiri wechoto zvinogona kuwedzerwa nekapu yekusveta. Mutungamiriri wekutyaira ndiye chidiki chechigaro chimwe nechimwe chevira. Furnace master, kana vamwe vanhu vakaraira mukombe wekusveta wekutyaira, mutyairi wekutyaira haabvumidzwe kudyisa.

6. Nhamba yekudya yekapu yekusveta inofanira kudzorwa. Mushure mekuwedzera, simbi yakarashika haibvumirwi kudarika pamusoro pemuromo wechoto chemoto induction melting. Simbi yakaraswa yakapararira pamuromo wechoto inofanira kucheneswa nemikombe yekusveta. Munguva yekudyisa, nzvimbo yakatenderedza yevira yekunyungudutsa induction inofanirwa kuchengetedzwa yakachena kudzivirira simbi yakaraswa kuti irege kudonha uye kukonzera kupisa kweiyo induction coil kana tambo yekubatanidza.

7. Zvinorambidzwa zvachose kuunganidza simbi yakawanda yezvimedu pachikuva, uye huwandu hwose hunodzorwa mukati me3 makapu ekusveta kuderedza kuoma kwekugadzirisa zvimedu.

8. Muchiitiko chekuputika, mufambisi anofanira kukurumidza kufuratira kumuromo wechoto, uye nokukurumidza kubva panzvimbo yacho.

9. Munguva yekudya kusati kwaitwa, zvinhu zvakareba uye zvakakura zvinofanira kugadzirwa uye kuwedzerwa muchoto kuti zvinyungudutse mudziva rakanyungudutswa nokukurumidza. Izvo zvinorambidzwa zvachose kuwedzera ivo zvakananga kukonzera bhiriji. Kana iyo midziyo yechoto ichiwanikwa ichivharisa, zambuko rinofanira kuparadzwa mukati me3 maminetsi. Chaji inokurumidza kunyungudutswa mudziva rakanyungudutswa. Kana bhiriji risingakwanisi kuparadzwa mukati memaminitsi e3, simba rinofanira kugurwa kana kuti bhiriji rinofanira kuparadzwa munzvimbo yekuchengetedza kupisa simba risati ratumirwa kune yakajairika smelting.

10. Kune dzimwe simbi dzakasara dzakafuta uye dzinoda vanhu vanopfuura 2 kuti vafambe muchoto, zvinorambidzwa zvachose kukanda muchoto. Kushandura kunofanira kuitwa pamucheto wechoto, uye nekunyatsosundirwa muchoto.

11. Chikafu chetubula chinowedzerwa muchoto, uye muromo wepamusoro wepombi unofanira kunge uri munzira yekuputira, uye haibvumirwi kuva munzira yekushanda kwevanhu.

Kune simbi inotonhora uye pfupi-yekupedzisira inoenderera mberi kukanda slabs mu slag ladle uye tundish, simbi yakanyungudutswa mu induction kunyunguduka choto inofanira kuwedzerwa yakatwasuka mushure mekunge simbi yakanyungudutswa yasvika kupfuura 2/3, uye haibvumidzwe kurova choto. lining.

13. Kana simbi yakanyungudutswa muchoto chekunyungudutsa induction inosvika kupfuura 70%, tora sampuli kuti uongororwe. Iwo masampula haafanire kuve akaremara senge maburi ekudzika, uye hapana simbi simbi ichapinzwa mumakapu emuenzaniso. Mushure mekuumbwa kwemakemikari mhedzisiro yemasampuli yabuda, vashandi vanogadzira zvinhu vanozobva pane yakazara mamiriro evira maviri. Sarudza huwandu hwealloy yakawedzerwa.

14. Kana mugumisiro wekuongorora kwemakemikari pamberi pevira unoratidza kuti kabhoni yakakwirira, wedzera mamwe iron oxide nuggets ye decarburization; kana zvichiratidza kuti kabhoni yakaderera, wedzera imwe nguruve iron nuggets ye recarburization; kana avhareji sarufa yevira mbiri iri pasi kana yakaenzana ne 0.055%, raki dzichapera panguva yekurova. Oxidized slag, wedzera huwandu hweiyo synthetic slag yakawedzerwa kune desulfurization. Panguva ino, tembiricha yekurova simbi inofanira kuwedzerwa zvakakodzera. Kana avhareji sarufa yevira mbiri iri ≥0.055%, simbi yakanyungudutswa inofanira kurapwa muchoto chakasiyana, ndiko kuti, chikamu chepamusoro-sarufa simbi yakanyungudutswa inodururwa muladle Iise mune mamwe mavira, wobva wawedzera mamwe. silicon simbi sheet inobaya mumavira maviri ekunyungudutsa uye ipapo kubaya. Kana iri phosphorus yakakwira, inogona kungogadziriswa muchoto chakasiyana.

15. Mushure mokunge simbi yose yakasvibiswa muchoto yakanyungudutswa, boka riri pamberi pechoto richazunungusa choto kuti chidururire slag. Mushure mekudurura slag, zvinorambidzwa zvachose kuisa mvura, mafuta, pendi uye tubular zvimedu muchoto. Zvakaoma uye zvakachena zvinhu zviri mukunyungudutswa. Inofanira kugadzirirwa. Mushure mokunge simbi yakanyungudutswa muchoto yakazara, chenesa slag zvakare. Mushure mekuchenesa, kurumidza kuwedzera alloy kugadzirisa kuumbwa. Iyo simbi inogona kubatwa kupfuura maminetsi matatu mushure mekunge alloy yawedzerwa. Chinangwa ndechekuita kuti alloy ive neyunifomu yakagadzirwa muchoto.

16. Kubata tembiricha: Kumusoro kunoramba kuchikandira 1650—1690; simbi yakanyungudutswa inenge 1450.

17. Pima tembiricha yesimbi yakanyungudutswa pamberi pechoto, uye kudzora curve yekufambisa magetsi zvinoenderana netembiricha yekupuruzira uye nguva yekubata inodiwa kuti irambe ichikanda. Izvo zvinorambidzwa zvachose kuchengetedza iyo induction yakanyunguduka muchoto chepamusoro tembiricha (tembiricha yekubata inodzorwa pazasi 1600 ℃)

18. Tembiricha inokwira nekukurumidza mushure mekugamuchira chiziviso chekuramba ichikanda simbi tapping. Chiyero chekupisa cheiyo induction yakanyunguduka muvira mune yakazara mvura mamiriro: anenge 20 ℃/min pamberi pe20 furnaces; inenge 30 ℃/min ye20-40 furnaces; inenge 30 ℃/min yemavira pamusoro pe40 Ndiyo 40°C/min. Panguva imwecheteyo, cherechedza kuti iyo yakakwirira yekushisa muchoto, inokurumidza kukurumidza kupisa.

19. Kana chirahwe chekutanga chikabirirwa, 100 kg yekugadzira slag inowedzerwa kune iyo ladle yekuchengetedza kupisa, uye mushure mekunge wechipiri wabikwa, 50 kg yekuvhara mumiriri inowedzerwa kune iyo ladle yekuchengetedza kupisa.

20. Mushure mekunge induction melting furnace yapera, chengetedza mamiriro ekugadzirisa zvakanyatsonaka, uye inorambidzwa zvachose kudira mvura muchoto kuti itonhorere; kana zvimwe zvikamu zvechigadziko chevira zvakasvibiswa zvakanyanya, choto chinofanira kugadziriswa zvakanyatsonaka isati yatanga moto, uye moto unofanira kumirira muchoto mushure mekugadzirisa. Kudyisa kunogona kuitwa chete mushure mekunge mvura yese yabuda. Kutanga, wedzera kapu yekusveta silicon simbi punch muchoto, uye wobva wawedzera zvimwe zvimedu. Imba yekutanga mushure mekugadzirisa huni inofanira kudzora magetsi emagetsi, kuitira kuti chigadziko chemoto chive nekugadzirisa sintering kuti ive nechokwadi chekugadzirisa Nokuda kwekuita kwechoto, zvinorambidzwa zvachose kuwedzera zvidimbu zvakakura zvemarara muchoto pakarepo mushure mekugadzirisa. choto.

21. Munguva yese yekugadzirwa kwekugadzira, zvinorambidzwa zvachose kuburitsa pani yevira kune kunze, uye iyo insulating rubber inofanira kuchinjwa munguva kana yakakanganiswa.
