Arc na lantarki tsarin narkewar tanderun

1. Nau’in rabo na albarkatun mai narke

A albarkatun kasa na lantarki baka makera na iya zama fashewa tander narkakkar da baƙin ƙarfe, baƙin ƙarfe slag, Magnetic rabuwa baƙin ƙarfe slag, slag karfe, karfe wanke yashi, guntun karfe, alade baƙin ƙarfe, da dai sauransu Babban manufar smelting shi ne don narke kayan da cewa Induction narkewa tanderu ba zai iya sarrafa. Ingancin tanderu iri-iri yana da kyau ko mara kyau. Kai tsaye yana shafar zagayowar narkarwa, tsadar narkewa, da samar da narkakken ƙarfe. Don haka, akwai manyan buƙatu masu zuwa don kayan caji daban-daban:

(1) Abubuwan da ke tattare da sinadarai na kayan caji daban-daban yakamata su kasance a sarari kuma su tsaya.

(2) Ba dole ba ne a haxa kowane nau’in kayan tanderu da kwantena da aka rufe, masu ƙonewa, fashewar abubuwa da jika don tabbatar da amincin ciyarwa da narkewa.

(3) Duk wani nau’in cajin yakamata ya kasance mai tsabta, ƙarancin tsatsa, kuma babu tarkace, in ba haka ba zai rage ƙarfin cajin, tsawaita lokacin narkewa, ko ma karya electrode. Sabili da haka, akwai hanyar haɗi mai mahimmanci a cikin rabo da ƙari na kayan.

(4) A cikin sharuddan gaba ɗaya girma na daban-daban yatsa karfe da slag karfe, giciye-section yankin kada ya wuce 280cm * 280cm. Zai shafi lokacin ciyarwa da wahalar ciyarwa. Manyan tarkace marasa tsari da kusan madauwari za su rugujewa cikin sauƙi da karye yayin narkewa. lantarki.

(5) Batching wani muhimmin sashi ne mai mahimmanci na narkewar wutar lantarki. Ko batching yana da ma’ana da ma’aikaci zai iya yin aikin narkawa akai-akai daidai da buƙatun tsari. Abubuwan da suka dace zasu iya rage lokacin narkewa. Kula da abubuwan sinadaran: Na farko, girman cajin dole ne a daidaita daidai gwargwado don cimma manufar ingantaccen shigarwa da sauri. Na biyu, ana amfani da kowane nau’i na caji a hade bisa ga ingancin narkakken ƙarfe da hanyar narkewa. Na uku shi ne cewa sinadaran dole ne su cika ka’idojin tsari.

(6) Game da buƙatun kayan da suka dace a cikin tanderun ginshiƙi: ƙasa yana da yawa, saman yana kwance, tsakiya yana da tsayi, kewaye da ƙananan ƙananan, kuma babu wani babban toshe a ƙofar tanderun, don haka rijiyar. ana iya shiga cikin sauri yayin narkewa kuma ba a gina gadoji.

2. Lokacin narkewa

A cikin tsarin narkewar wutar lantarki, lokacin daga lokacin fara wutar lantarki har zuwa lokacin da caji ya narke gaba ɗaya ana kiran shi lokacin narkewa. Lokacin narkewa yana lissafin kashi 3/4 na duk tsarin narkewa. Ayyukan lokacin narkewa shine saurin narkewa da zafi da caji tare da ƙarancin wutar lantarki yayin tabbatar da rayuwar tanderun. Kuma zaɓi slag a cikin lokacin narkewa don tabbatar da kyakkyawan tasirin arc na murhun wutar lantarki, wanda shine ɗayan mahimman yanayi don inganta rayuwar sabis na tanderun. Yana daya daga cikin yanayin da ake bukata don ƙara yawan rayuwar sabis na tanderun. Domin asalin narkakkar baƙin ƙarfe yana narkar da shi ne a cikin tanderun wutar lantarki, yana cikin yanayi na narkewar alkaline. Ko da ba a kara lemun tsami a lokacin narkewa ba, sakamakon samuwar kumfa slag a cikin tanderun ya fi kyau, kuma slag kuma dan kadan ne alkaline (lantarki arc makera refractories). Siffofin kuma sune alkaline). Sabili da haka, slagging ba tare da lemun tsami ba yana da tasiri kadan akan rayuwar sabis na tanderun. A lokacin lokacin narkewa, murhun arc yana amfani da kayan arcing a matsayin babban abu, kuma ana amfani da iskar oxygen azaman mataimaki don haɓaka kayan a cikin yankin sanyi kusa da bangon tanderun don rage lokacin narkewa.

3. Lokacin farfadowa

Lokacin daga ƙarshen narkewa zuwa tapping shine lokacin raguwa. A lokacin lokacin raguwa, ƙara yawan adadin silicon carbide (raw abu 4% -5%) don dakatar da busa iskar oxygen, kuma an rufe ƙofar tanderun, don haka an samar da yanayi mai kyau na ragewa a cikin tanderun ta hanyar ƙananan wuta da kuma babban halin yanzu. . An kafa motsi mai tsayi mai tsayi don deoxidize da rage oxides a cikin slag a saman don ƙara yawan amfanin ƙasa. Gabaɗaya, lokacin raguwa yana sarrafawa tsakanin mintuna 10-15, kuma a ƙarshe ana sarrafa zafin da ake buƙata don sakin slag, kuma an gama aiwatar da aikin narkewa.

4. Kudin narkewa

Farashin narka ɗanyen ƙarfe na ƙarfe a cikin tanderun baka na lantarki yana tasiri kai tsaye ƙimar amfani da tanderun baka na lantarki. Ko da yake zaɓin albarkatun ƙasa don murhun baka na lantarki ya fi na tanderun narkewar induction, dole ne a haɗa farashin ƙarfe na baƙin ƙarfe tare da ƙananan farashi. Binciken farashi na murhun narkewar shigar da wutar lantarki da wutar lantarki, da albarkatun ƙasa; muddin wutar baka ta wutar lantarki ta dace daidai da adadin caji, jimillar farashi zai yi ƙasa da na tanderun narkewa. Dangane da farashin wutar lantarki a lardin Shandong, an kiyasta cewa kowane tan na narkakkar ƙarfe za a iya rage yuan 130 kusan.

Daga teburin da ke sama, ana iya ganin cikakken ƙarfin wutar lantarki na narke duplex na iya ceton 230Kwh na wutar lantarki, wanda ya kai kashi 37% idan aka kwatanta da narkakken tanderun da ke narkewar ton na baƙin ƙarfe. Koren tasirin ceton makamashi na wannan tsari yana da fice sosai.

5. Rayuwa sabis na layi

Bisa ga halaye na wutar lantarki arc tanderu smelting, da tanderun shekaru iya isa dogon tanderu shekaru. Takamammen bincike shine kamar haka:

(1) Sakamakon zafin zafin jiki mai zafi: rufin tanderun yana gabaɗaya a yanayin zafi mai zafi da yanayin zafi sama da 1600 ℃, kuma yana da tsayayya da saurin sanyi da zafi wanda zai haifar da babbar illa ga rufin tanderun; yayin da wutar lantarki baka makera smelting narkakkar baƙin ƙarfe, da yawan zafin jiki ne kullum sarrafa a game da 1500 ℃, don haka Lalacewar high zafin jiki ga tanderun rufi ne m negligible. Saboda ci gaba da daidaita narkakken baƙin ƙarfe don samar da ci gaba mai narkewa kuma a lokaci guda don isa digiri 1550 na zafin iskar oxygen da ke busawa daga cikin tanderun, rayuwar sabis na rufin tanderun za a iya inganta sosai.

(2) Tasirin yashwar abun da ke tattare da sinadarai: Na’urar tanderun wutar lantarki ta wutar lantarki sune abubuwan da ke hana ruwa gudu. Matsakaicin albarkatun albarkatun kasa shine cewa karfen karfe yana tare da babban adadin alkaline slag, wanda ya sa yawan cajin wutar lantarki ya zama alkaline. Rushewar bango ma kadan ne. Yanayin smelting na alkaline shine ainihin yanayin don inganta rayuwar tanderun, amma slag yana da kauri sosai, wanda zai samar da yankin zafin jiki a gida, wanda zai rage rayuwar sabis na rufin tanderun.

(3) Radiation na baka yana nunawa ta hanyar tasirin kumfa slag submerged arc a lokacin narkewa, wanda zai iya rage zagayowar narkewar wutar lantarki. A lokaci guda kuma, kyakkyawan tasirin arc mai nutsewa zai iya rage zafin zafi zuwa rufin tanderun, ta haka yana haɓaka rayuwar tanderun.

(4) karo na inji da girgiza kuma za su shafi rayuwar sabis na tanderun. Hanyoyin ciyarwa masu ma’ana kuma za su ƙara rayuwar sabis na tanderun. Yin caji da rarrabawa ba su da ma’ana, ko tankin kayan ya ɗaga sama da yawa, kuma gangaren tanderun na iya ɗaukar manyan abubuwa masu nauyi. Rikici, girgizawa da tasiri suna haifar da ramuka, duk waɗanda ke rage rayuwar rufin tanderun. Bugu da ƙari, bisa ga bangon wutar lantarki na wutar lantarki shine yanki mai zafi, cajin zai iya yada kayan zuwa wadannan maki uku, wanda zai kara yawan rayuwar sabis na rufin tanderun.

(5) Hanyar busa iskar oxygen kuma za ta shafi rayuwar sabis na tanderun. Oxygen yana aiki azaman mai taimako baka mai taimako a cikin tanderun lantarki. Gabaɗaya, bangarorin biyu na bangon tanderun da ƙofar tanderun sune yankin sanyi, kuma ana amfani da lantarki don aika kayan sinadarai. Tsawaitawa da m iskar oxygen busawa dabaru na iya rage smelting sake zagayowar da kuma kara da wutar makera rayuwa (bisa ga daban-daban abu yanayi, babban tubalan na kayan da aka zaba domin busawa, da kuma iskar oxygen ba a hura a kan tanderun kasa da kuma tanderu bango kamar yadda zai yiwu. ), da kuma busa a lokaci guda Lokacin iskar oxygen bai kamata ya yi tsayi da yawa ba don kauce wa yanayin zafi na gida kusa da bangon tanderun da kuma rushewar bangon tanderun.
