Ntchito ndi Katundu wa Graphite Electrode

Gulu la ma electrode a graphite

Nthawi zonse mphamvu ya graphite elekitirodi (RP); Mphamvu yapamwamba ya graphite elekitirodi (HP); Standard-ultra high power graphite elekitirodi (SHP); Ultra high power graphite electrode (UHP).

1. Ntchito mu ng'anjo magetsi arc steelmaking

graphite elekitirodi zipangizo angagwiritsidwe ntchito makamaka magetsi ng'anjo steelmaking. Kupanga zitsulo za ng'anjo yamagetsi ndiko kugwiritsa ntchito maelekitirodi a graphite kuti adziwitse zomwe zikuchitika mu ng'anjoyo. Mphamvu yamagetsi imatha kutulutsa ma arc kudzera m'malo otsika a ma elekitirodi, ndikugwiritsa ntchito kutentha kopangidwa ndi arc kusungunula. Kukula kwa capacitance, okonzeka ndi maelekitirodi graphite ndi diameters osiyana, angagwiritsidwe ntchito mosalekeza kwa maelekitirodi, abutting motsutsana kugwirizana maelekitirodi pa mfundo electrode. Graphite ntchito steelmaking monga elekitirodi nkhani nkhani pafupifupi 70-80% ya okwana graphite elekitirodi mowa ku China.

2. Amagwiritsidwa ntchito mu ng'anjo yamagetsi yotentha yomira

Amagwiritsidwa ntchito kwambiri popanga ferroalloy yachitsulo, silicon yoyera, phosphorous yachikasu, calcium carbide ndi matte. Amadziwika kuti m'munsi mwa electrode conductive amaikidwa m'manda, kotero kuti kuwonjezera pa kutentha komwe kumapangidwa ndi arc pakati pa mbale yamagetsi ndi chiwongolero, zomwe zikuchitika panopa zimadutsa pamoto Kutentha kumapangidwanso ndi kukana. wa mlandu.

3. Amagwiritsidwa ntchito mu ng'anjo yotsutsa

Popanga, ng'anjo za graphitization zopangira zinthu za graphite, ng'anjo zosungunula zosungunula magalasi aukadaulo ndi kupanga, ndi ng'anjo zamagetsi za silicon carbide zonse ndi ng'anjo zotsutsa. Kasamalidwe kazinthu mu ng'anjo sikuti amangotenthetsa, komanso ndi chinthu chotenthetsera.

4. Zinthu zooneka ngati mwapadera monga ma thabwa otentha otentha ndi zinthu zotenthetsera za ng'anjo zamagetsi za vacuum

Komanso tisaiwale kuti pakati zipangizo graphite mu atatu mkulu-kutentha gulu zipangizo kuphatikizapo maelekitirodi graphite, graphite nkhungu ndi graphite crucibles, pa kutentha, pakati pa zipangizo zitatu graphite, graphite n'zosavuta oxidize ndi kuwotcha, kuti mpweya. wosanjikiza wa zinthu pulasitiki pamwamba , Kupititsa patsogolo porosity ndi dongosolo lotayirira la moyo.
