Graphite electrodeinonyanya kushandiswa muEAF steelmaking. Electric furnace steelmaking ndeye kushandisa graphite electrode kuunza ikozvino muchoto. Ikozvino yakasimba inogadzira arc discharge kuburikidza negasi pamucheto wezasi we electrode, uye kupisa kunoitwa nearc kunoshandiswa kunyungudutsa. Maererano nehuwandu hwevira remagetsi, magirafu emagetsi ane madhayamita akasiyana anoshandiswa. Kuti uite kuti magetsi arambe achishandiswa, magetsi anobatanidzwa ne electrode threaded joint. Thegraphite electrodenokuda kwekugadzirwa kwesimbi kune 70-80% yehuwandu hwehuwandu hwe graphite electrode. 2, Inoshandiswa mumugodhi wekupisa simba revira. Chimiro chayo ndechokuti chikamu chezasi che electrode conductive chakavigwa mubhadharo. Nokudaro, kunze kwekupisa kunogadzirwa nearc pakati peplate yemagetsi uye kubhadharisa, kupisa kunogadzirwawo nekupikisa kwemutero apo ikozvino inopfuura nemubhadharo. 3, Graphitization choto, girazi rinonyunguduka choto uye choto chemagetsi chekugadzira zvigadzirwa zvegraphite ese mavira ekupikisa. Zvinhu zviri muchoto hazvisi kungopisa kupisa chete, asiwo kupisa chinhu. Kazhinji, iyo conductive graphite electrode inopinzwa muchoto chemusoro madziro pamagumo echoto, saka iyo conductive electrode haina kupedzwa nguva dzose.
Nzvimbo dzekushandisa:
(1) Inoshandiswa muchoto chemagetsi arc steelmaking, mushandisi mukuru wegraphite electrode. MuChina, kubuda kwesimbi yeEAF kunokwana gumi nesere muzana yekubuda kwesimbi, uye graphite electrode yekugadzira simbi inokwana 70% ~ 80% yehuwandu hwekushandiswa kwegraphite electrode. Electric furnace steelmaking ndeye kushandisa graphite electrode kuunza ikozvino muchoto, uye kushandisa yakakwira tembiricha yekupisa sosi inogadzirwa nearc pakati pekupera kwe electrode uye kuchaja kunyungudika.
2) Inoshandiswa muchoto chearc yakanyura; submerged arc furnace inonyanya kushandiswa kugadzira silicon yeindasitiri uye yero phosphorous, zvichingodaro inoratidzwa nekuti chikamu chezasi cheelectrode conductive chakavigwa muchaji, ichigadzira arc mujaja yekuchaja, uye kupisa iyo charge nekushandisa kupisa simba. yakagadzirwa nekupikisa kwechaji pachayo. Iyo yakanyura arc choto ine yakakwira density iripo inoda graphite electrode, semuenzaniso, ingangoita 100kg graphite electrode inodiwa kune yega 1t kugadzirwa kwesilicon, uye inenge 100kg graphite electrode inodiwa kune yega 1t kugadzirwa kwesilicon Inoda 40 kg yegraphite electrode inodiwa t yero. phosphorus.
(3) Inoshandiswa muvira rekudzivirira; graphitization choto chekugadzira zvigadzirwa zvegraphite, choto chekunyungudusa girazi uye choto chemagetsi chekugadzira silicon carbide zvese ndezvevira rekudzivirira. Zvinhu zviri muchoto zvose zvinopisa kupisa uye chinhu chinopisa. Kazhinji, iyo conductive graphite electrode yakamisikidzwa muchoto musoro madziro pamagumo echoto chekudzivirira, uye graphite electrode inoshandiswa pano hairambe ichipedzwa.
(4) Inoshandiswa kugadzirira-yakakosha-chimirographite zvigadzirwa; iyo isina chinhu yegraphite electrode inoshandiswawo kugadzira akasiyana akasarudzika-akaumbwa zvigadzirwa zvegraphite senge crucible, mold, chikepe dishi uye kupisa muviri. Semuenzaniso, muindasitiri yegirazi yequartz, 10t graphite electrode blank inodiwa kune yega yega 1t magetsi inonyungudika chubhu; 100kg graphite electrode isina inodiwa kune yega yega 1t quartz zvidhinha.
