Mene ne Rotor na Graphite Degassing?

Na'urar jujjuyawar graphiteAna amfani da shi sosai a masana'antar simintin ƙarfe, musamman a cikin narkewa da tace aluminum da ƙarfensa, kuma a wasu lokuta don maganin zinc mai narkewa, ƙarfe mai tagulla da sauran ƙarfe marasa ƙarfe.
Su muhimmin abu ne a cikin tsarin cire gas. Ta hanyar juyawa da allurar iskar gas mara aiki, rotor yana cire iskar gas da aka narkar da kuma wani ɓangare na abubuwan da aka haɗa daga ƙarfe mai narkewa yadda ya kamata, yana hana ramuka, ƙuraje da sauran lahani a cikin simintin, don haka yana tabbatar da ingancin samfuran ƙarshe na ciki da na saman.

1. Kayan aiki

Ana yin amfani da rotors na degassing na graphite daga graphite mai tsabta ko isostatic graphite saboda dalilai masu zuwa:

• Kyakkyawan aiki mai zafi mai kyau:
  Suna iya kiyaye daidaiton tsarin a yanayin zafi na ƙarfe mai narkewa (misali, kusan digiri 700 na Celsius ga aluminum mai narkewa).

• Daidaiton sinadarai:
  Suna nuna ƙarancin danshi ga narkakken aluminum da sauran ƙarfe, wanda ke taimakawa wajen rage zaizayar ƙasa da kuma bin ƙarfe sosai.

• Ƙarfin juriyar tsatsa:
  Suna iya jure wa hari daga ƙarfe mai narkewa da wasu kwararar ruwa.

• Kyakkyawan injina:
  Ana iya juya graphite, niƙa shi da haƙa shi, wanda hakan ke sauƙaƙa ƙera rotors a cikin tsari da girma dabam-dabam don dacewa da ƙira daban-daban na tanda da buƙatun sarrafawa.

2. Ka'idar Aiki da Manyan Ayyuka

Juya narkewar narkewa don haɓaka fitar da iskar gas

A lokacin aiki, ana nutsar da rotor ɗin graphite a cikin ƙarfe mai narkewa kuma injin yana tuƙa shi da babban gudu.

• Juyawan yana haifar da tasirin motsawa, wanda ke sa ƙarfen da ke narke ya kwarara da ƙarfi;

• Wannan yana taimakawa wajen kawo iskar gas da aka narkar da su da kuma abubuwan da suka haɗu da su waɗanda aka kama ko kuma ba su da daidaito a cikin narkewar su zuwa saman, wanda hakan ke hanzarta sakin iskar gas da kuma flotation na slag.

Alluran iskar gas mara aiki don cire iskar gas mai inganci

Yawanci ana tsara hanyoyin iskar gas na ciki a cikin rotor ta yadda za a iya shigar da iskar gas marasa aiki (galibi argon ko nitrogen) cikin ƙarfen da aka narke.

• A ƙarƙashin aikin na'urar juyawa, iskar gas mara aiki ta rabu zuwa adadi mai yawa na kumfa mai laushi;

• Yayin da waɗannan kumfa ke tashi ta cikin narkewar, suna musanya da hydrogen da aka narkar da shi da sauran iskar gas a cikin ƙarfen kuma suna fitar da su daga narkewar;

• Wasu ƙananan oxides da abubuwan da ba na ƙarfe ba suna manne da saman kumfa kuma ana haɗa su zuwa saman, inda za a iya cire su ta hanyar cire su.

3. Yanayin Aikace-aikacen da Aka saba

• Cire gas kafin a yi amfani da shi:
  Kafin a yi amfani da aluminum alloy simintin, ana yi wa narkewar magani don cire gas da kuma rage yawan danshi don rage yawan danshi da kuma inganta yawan danshi.

• Tsarin narkewa da tacewa:
  A cikin tanderun narkewa ko tanderun tacewa, ana amfani da rotors masu cire gas don cire hydrogen da wasu oxides daga narkewar, ta haka ne ake inganta tsaftar narkewar.

4. Nau'o'i da Siffofin Tsarin Rotors na Graphite Degassing

Dangane da nau'in ƙarfe da ake sarrafawa, ƙirar tanderu da kuma yawan wutar lantarki da ake buƙata, ana samun rotors na graphite degassing a cikin ƙira daban-daban, kamar:

• Na'urorin degas na Rotary:
  Mafi kyawun mafita ga maganin narkewar aluminum. Ana ɗora rotor ɗin a kan sandar mota kuma yana juyawa a cikin kwano na ƙarfe mai narkewa ko tanderun tacewa.

• Tsarin kan rotor daban-daban:
  Misali, kan ruwa mai yawa ko ƙira masu ingantaccen kwarara waɗanda ke samar da kumfa mai kyau da daidaito don haɓaka ingancin cire gas.

• Tsarin da aka haɗa ko aka raba:
  Ana yin amfani da wasu na'urorin juyawa a matsayin guda ɗaya (shaft da head), yayin da wasu kuma ke amfani da haɗin zare don haka kawai kan rotor da ya lalace ne ake buƙatar a maye gurbinsa, wanda hakan ke rage farashin gyarawa.

5. Fa'idodi da Daraja

• Kyakkyawan juriya:
  Graphite yana da ƙarfin juriya ga tsatsa da kuma juriya ga girgizar zafi, wanda ke bawa rotor damar kiyaye tsawon rai mai kyau a cikin yanayin ƙarfe mai narkewa.

• Ingantaccen aikin degassing:
  Haɗuwar iskar gas mai juyawa da kuma allurar iskar gas mara aiki yana rage yawan iskar gas da ke narkewa a cikin ƙarfe sosai.

• Babban ci gaba a ingancin ƙarfe:
  Bayan an cire iskar gas da ƙazanta masu cutarwa, zagayawar porosity na siminti yana raguwa kuma tsarin ciki yana ƙaruwa, yana inganta halayen injiniya da ingancin saman.

Mai tunatarwa:A tsawon lokaci, na'urar rotor ta graphite za ta lalace saboda yawan zafin jiki, matsin lamba na injiniya da kuma iskar shaka, don haka ana buƙatar kulawa da maye gurbin akai-akai.
