Intshayelelo ye-graphite electrode

I-electrode yegrafayithiIsetyenziswa kakhulu ekwenzeni intsimbi ye-EAF. Ukwenza intsimbi yesithando sombane kukusebenzisa i-graphite electrode ukungenisa umbane kwisithando somlilo. Umbane onamandla uvelisa i-arc discharge ngegesi kwicala elisezantsi le-electrode, kwaye ubushushu obuveliswa yi-arc busetyenziselwa ukunyibilikisa. Ngokwendlela isithando sombane esisebenza ngayo, kusetyenziswa ii-graphite electrodes ezineedayamitha ezahlukeneyo. Ukuze kwenziwe ii-electrodes zisetyenziswe rhoqo, ii-electrodes ziqhagamshelwe yi-electrode threaded joint.i-electrode yegrafayithiUkwenza intsimbi kubiza i-70-80% yenani lilonke le-electrode ye-graphite. 2. Isetyenziswa kwisithando samandla obushushu semayini. Uphawu lwayo kukuba inxalenye esezantsi ye-electrode eqhubayo ingcwatywe kwitshaja. Ke ngoko, ukongeza kubushushu obuveliswa yi-arc phakathi kwepleyiti yombane kunye netshaja, ubushushu buveliswa nakukumelana kwetshaja xa umbane udlula kwitshaja. 3. Isithando se-Graphitization, isithando sokunyibilikisa iglasi kunye nesithando sombane sokwenza iimveliso ze-graphite zonke zii-furnace zokumelana. Izinto ezikwisithando azigcini nje ngokuxhathisa ukufudumeza, kodwa zikwayinto yokufudumeza. Ngokwesiqhelo, i-electrode ye-graphite eqhubayo ifakwa eludongeni lwentloko yesithando ekupheleni kweziko, ngoko ke i-electrode eqhubayo ayisetyenziswa rhoqo.

Iindawo zokufaka isicelo:

(1) Isetyenziswa kwisithando sombane sokwenza intsimbi, esisetyenziswa kakhului-electrode yegrafayithiETshayina, imveliso yentsimbi ye-EAF ibandakanya malunga ne-18% yemveliso yentsimbi eluhlaza, kwaye i-graphite electrode yokwenza intsimbi ibandakanya i-70% ~ 80% yexabiso lilonke lokusetyenziswa kwe-graphite electrode. Ukwenza intsimbi ye-furnace yombane kukusebenzisa i-graphite electrode ukungenisa umbane kwi-furnace, kwaye kusetyenziswe umthombo wobushushu obuphezulu obuveliswa yi-arc phakathi kwesiphelo se-electrode kunye netshaja yokunyibilikisa.

2) Isetyenziswa kwi-oven ye-arc engaphantsi komhlaba; i-oven ye-arc engaphantsi komhlaba isetyenziselwa kakhulu ukuvelisa i-silicon yemizi-mveliso kunye ne-phosphorus etyheli, njl.njl. ibonakaliswa kukuba inxalenye esezantsi ye-electrode eqhubayo ingcwatywe kwi-charge, yenze i-arc kumaleko we-charge, kwaye ifudumeze i-charge ngokusebenzisa amandla obushushu aveliswa kukuxhathisa kwe-charge ngokwayo. I-oven ye-arc engaphantsi komhlaba ene-current density ephezulu idinga i-graphite electrode, umzekelo, i-electrode ye-graphite emalunga ne-100kg iyadingeka kwimveliso nganye ye-silicon ye-1t, kwaye i-electrode ye-graphite emalunga ne-100kg iyadingeka kwimveliso nganye ye-silicon ye-1t. Malunga ne-40 kg ye-electrode ye-graphite iyadingeka kwi-phosphorus etyheli ye-t.

(3) Isetyenziselwa isithando somlilo esichaseneyo; isithando somlilo esidibanisayo ukuvelisa iimveliso zegrafiti, isithando somlilo esinyibilikisa iglasi kunye nesithando sombane sokwenza i-silicon carbide zonke zezesithando somlilo esichaseneyo. Izinto ezikwisithando somlilo zombini zichasene nokufudumeza kunye nezinto ezifudunyezwayo. Ngokubanzi, i-electrode yegrafiti eqhubayo ifakwa eludongeni lwentloko yesithando somlilo ekupheleni kwesithando somlilo esichaseneyo, kwaye i-electrode yegrafiti esetyenziswa apha ayisetyenziswa rhoqo.

(4) Isetyenziselwa ukulungiselela imilo ekhethekileyoiimveliso zegrafayithi; i-blank ye-graphite electrode ikwasetyenziselwa ukucubungula iimveliso ezahlukeneyo ze-graphite ezinemilo ekhethekileyo ezifana ne-crucible, i-mold, isitya senqanawa kunye nomzimba wokufudumeza. Umzekelo, kushishino lweglasi ye-quartz, i-10t graphite electrode blank iyadingeka kwityhubhu nganye yokunyibilikisa yombane ye-1t; i-100kg graphite electrode blank iyadingeka kwisitena ngasinye se-1t quartz.
