Chifukwa chiyani ma Graphite Electrodes Amagwiritsidwa Ntchito mu Electric Arc Furnace

 

• Conductivity

Graphite ndi kondakitala wabwino kwambiri wamagetsi, ndikupangitsa kuti ikhale chisankho choyenera kuti chigwiritsidwe ntchito mu ng'anjo zamagetsi zamagetsi.Pamene mphamvu yamagetsi yamagetsi imadutsa mu electrode, imapanga arc yamagetsi, yomwe imathandizira kusungunuka kwa zipangizo zamagetsi.Kuwongolera kwapamwamba kwa graphite kumathandizira kutengera mphamvu moyenera panthawi yosungunuka.

• Thermal Resistance

Chimodzi mwa zifukwa zazikulu zomwe ma elekitirodi a graphite amakondedwa m'ng'anjo zamagetsi zamagetsi ndi kukana kwawo kwapadera kwa kutentha.Ng'anjo zamagetsi zamagetsi zimagwira ntchito kutentha kwambiri, nthawi zambiri kufika pa madigiri 3000 Celsius.Ma electrode a graphite amagwiritsa ntchito ng'anjo yamagetsi yamagetsiimatha kupirira kutentha kwakukulu kumeneku popanda kuwononga kwambiri kapena kutulutsa oxidizing, kuwapanga kukhala oyenera kugwiritsidwa ntchito motalikirapo mumikhalidwe yovuta ngati imeneyi.

• High Melting Point

Graphite ili ndi malo osungunuka kwambiri pafupifupi madigiri 3,600 Celsius.Khalidweli limapangitsa maelekitirodi a graphite kukhala oyenera kugwiritsidwa ntchito m'ng'anjo zamagetsi zamagetsi, pomwe kutentha kwambiri kumafunika kusungunula zida zolizira.Malo osungunuka kwambiri amatsimikizira kuti ma electrode amasunga umphumphu ndi ntchito zawo panthawi yonse yosungunuka.

• Chemical Inertness

Ma elekitirodi a graphite ali ndi mphamvu zokhala ndi mphamvu zopanga mankhwala, kutanthauza kuti amalimbana kwambiri ndi kusintha kwamankhwala kapena dzimbiri kuchokera kuzitsulo zosiyanasiyana zosungunula ndi zotuluka zomwe zimapezeka muzotengera.Kusakhazikika kwamankhwala kumeneku kumatsimikizira kuti ma elekitirodi a graphite amakhalabe osawonongeka ndikuchita bwino, kulola moyo wautali wa elekitirodi ndikuchepetsa nthawi yopumira m'malo mwa electrode.

• Mphamvu zamakina

Kuphatikiza pa matenthedwe awo abwino kwambiri komanso mankhwala, ma electrode a graphite amawonetsanso mphamvu zamakina apamwamba.Amatha kupirira kupsinjika kwakukulu kwakuthupi ndi kugwedezeka komwe kumachitika chifukwa cha arc yamagetsi ndi zida zopangira.Mphamvu zamakina zama electrode a graphite zimapangitsa kuti pakhale bata komanso zimachepetsa chiopsezo cha kusweka kwa ma elekitirodi panthawi yosungunuka.

• Zabwino Machinability

Ubwino wina wa maelekitirodi a graphite ndi luso lawo labwino.Opanga amatha kuwaumba mosavuta ndikuwapanga momwe amafunira, kulola ma elekitirodi osinthika kuti akwaniritse zofunikira zamitundu yosiyanasiyana ya ng'anjo yamagetsi yamagetsi.Kusinthasintha kumeneku pakupanga kumapangitsa kuti ma elekitirodi agwirizane ndi momwe ng'anjo imapangidwira ndikuwongolera kusungunuka kwathunthu.

• Mtengo-Kuchita bwino

Ma electrode a graphite amapereka njira yotsika mtengo yopangira ng'anjo yamagetsi yamagetsi.Ngakhale ali ndi zinthu zapadera, ma elekitirodi a graphite ndi otsika mtengo poyerekeza ndi zida zina zama elekitirodi.Moyo wotalikirapo wautumiki, kukana kuwonongeka, ndi kuchepetsedwa kwa nthawi yosinthira zonse zimathandizira kuti ma elekitirodi a graphite akhale okwera mtengo.

• Ubwino Wachilengedwe

Kugwiritsa ntchito ma electrode a graphite kumaperekanso phindu la chilengedwe.Zida zopangira magetsi pogwiritsa ntchito ma electrode a graphiteamadya mphamvu zochepa poyerekeza ndi ng'anjo zakale, zomwe zimapangitsa kuti mpweya wowonjezera kutentha ukhale wotsika.Kuphatikiza apo, kuthekera kwa ma elekitirodi a graphite kupirira kutentha kwambiri komanso kukana dzimbiri kumachepetsa kufunika kosinthitsa ma elekitirodi pafupipafupi, zomwe zimapangitsa kuchepa kwa zinyalala komanso kukhazikika kwa chilengedwe.

Ma electrode a graphite amagwiritsidwa ntchito kwambiri m'ng'anjo zamagetsi zamagetsi chifukwa chapamwamba kwambiri, kukana kutentha, malo osungunuka kwambiri, kusungunuka kwamankhwala, mphamvu zamakina, kutheka bwino, kutsika mtengo, komanso kupindulitsa chilengedwe.Ma elekitirodi awa amagwira ntchito yofunika kwambiri pothandizira njira zosungunulira zitsulo ndipo ndizofunikira kwambiri m'mafakitale ambiri.Kukula kosalekeza ndi kuwongolera kwa ma electrode a graphite kumathandizira kupititsa patsogolo komanso kukhazikika kwaukadaulo wa ng'anjo yamagetsi yamagetsi.
