Ukusetyenziswa kunye neempawu zee-electrode zegraphite:

1. Isetyenziswe kwisithando sombane se-arc steelmaking

Iielectrode zegraphite zisetyenziswa ikakhulu kwi-steelmaking yesithando sombane.I-Electric furnace steelmaking kukusebenzisa i-electrode yegraphite ukwazisa ngoku kwi-oven.Umbane onamandla udlula igesi ekupheleni kwe-electrodes ukuvelisa ukukhutshwa kwe-arc, kwaye ukushisa okwenziwa yi-arc kusetyenziselwa ukunyibilika.Ngokutsho komthamo wesithando sombane, i-electrode yegraphite ene-diameter eyahlukeneyo isetyenziswa.Ukuze wenze i-electrodes isetyenziswe ngokuqhubekayo, i-electrodes ixhunywe ngamacandelo adibeneyo e-electrode.I-electrodes yegraphite ye-akhawunti ye-steelmaking malunga ne-70-80% yexabiso elipheleleyo le-electrode yegraphite.

2. Isetyenziswa kwiziko lombane elishushu eliphantsi kwamanzi

I-graphite electrode entywiliselwe kwiziko lombane elishushu lisetyenziselwa ukuvelisa i-ferroalloy, isilicon esulungekileyo, i-phosphorus etyheli, i-matte kunye ne-calcium carbide, njl. eveliswa yi-arc phakathi kwepleyiti yombane kunye nentlawulo, i-Heat yangoku iveliswa ngokuchasana kwentlawulo xa idlula kwintlawulo.Itoni nganye yesilicon idinga ukusebenzisa malunga ne-150kg ye-electrode yegraphite, kwaye itoni nganye yephosphorus emthubi kufuneka isebenzise malunga ne-40kg ye-electrode yegraphite.

3. Isetyenziswe kwisithando somlilo

Amaziko okwenziwa kwegrafiti ukuze kuveliswe iimveliso zegraphite, iziko lokunyibilikisa iglasi enyibilikayo, kunye neziko lombane lokuvelisa isilicon carbide zonke zizitofu zokuxhathisa.Izinto ezikwi-furnace zombini zi-resistors zokufudumeza kunye nezinto eziza kufudumeza.Ngokuqhelekileyo, i-electrodes ye-graphite yokuqhuba ifakwe kwindonga yokutshisa ekupheleni kweziko, ukwenzela ukuba i-electrode conduction ingadli ngokuqhubekayo.

4. Ukulungiselela

Inani elikhulu leentsimbi zegraphite electrode blanks zikwasetyenziselwa ukucubungula iimveliso ezahlukeneyo ezimile njengeecrucibles, izikhephe zegraphite, iimolds ezishushu kunye nezinto zokufudumeza zevacuum zombane.Kufuneka kuqatshelwe ukuba kukho iintlobo ezintathu zezinto zokwenziwa kwezixhobo zegraphite kwiqondo lokushisa eliphezulu, kubandakanywa i-electrodes yegraphite, i-graphite molds kunye ne-graphite crucibles.I-graphite kwezi zinto zintathu zithandwa kwi-oxidative combustion reactions kumaqondo obushushu aphezulu, okukhokelela kumaleko wekhabhoni kumphezulu wezinto.Ukunyuka kwe-porosity kunye nesakhiwo esikhululekile sichaphazela ubomi benkonzo.

Iielectrode zegraphite zenziwe ikakhulu ngepetroleum coke kunye nenaliti yecoke, kwaye i-coal tar pitch isetyenziswa njengesibophelelo.Zenziwa ngokubala, ukudibanisa, ukuxova, ukucofa, ukuqhotsa, igraphitization, kunye nomatshini.Bakhulula amandla ombane ngendlela yee-arcs kwii-oven arc zombane.Ii-conductors zokufudumeza kunye nokunyibilika kwentlawulo zinokwahlulwa zibe yi-electrode yegraphite yamandla aqhelekileyo, amandla aphezulu e-graphite electrode kunye ne-ultra-high power graphite electrode ngokwezikhombisi zabo zomgangatho.
