I-RP Graphite Electrode yeLadle Furnace
Ukuhlukaniswa Kwe-Graphite Electrodes
Isithando somlilo esenza i-arc steel sikagesi singahlukaniswa sibe isithando somlilo esijwayelekile samandla kagesi (cishe 300KVA ngethani), isithando somlilo esinamandla amakhulu (cishe 400kVA ngethani) kanye nesithando somlilo esinamandla amakhulu (500 ~ 1200KV/A ngethani) ngokusho umthamo we-transformer ngethani ngalinye lomthamo wesithando somlilo.
Ngokusho kwezigaba zamandla kagesi we-electric furnace steel making, futhi ngokusho komehluko wezinto ezingavuthiwe ezisetshenziswa ekukhiqizeni ama-electrode kanye nezinkomba zomzimba nezamakhemikhali ze-electrode eqediwe, i-graphite electrode ihlukaniswe yaba izinhlobo ezintathu: amandla avamile we-graphite electrode (RP) , amandla aphezulu e-graphite electrode (HP) kanye ne-ultra-high power graphite electrode (UHP).
Ukwethulwa kwe-RP Graphite Electrode
I-RP graphite electrode yenziwe ngokuyinhloko nge-petroleum coke njengezinto zokusetshenziswa kanye ne-asphalt yamalahle njengesibopho ngokusebenzisa i-calcination, i-batching, ukuxova, ukubumba, ukubhaka, i-graphitization kanye nomshini.
I-Graphite Electrode iyi-conductor ekhulula amandla kagesi esithandweni se-arc sikagesi ukuze kushiswe futhi kuncibilike izinsalela zensimbi.
Izici
I-RP graphite electrode ikhiqizwa nge-petroleum coke, enezinga lokushisa eliphansi le-graphitization.inezici ezilandelayo:
1.Ukumelana okuphezulu
2.I-coefficient yokunweba yomugqa omkhulu
3.Ukumelana nokushaqeka okushisayo okungalungile
4.Ukuminyana okuvumelekile kwamanje kuphansi
Ukusetshenziswa kwe-RP Graphite Electrode
(1) Ukwenza insimbi ku-Electric Arc Furnace (EAF) kanye neLadle Furnace (LF)
I-RP Graphite electrode isetshenziswa kakhulu ku-LF/EAF ekwenzeni insimbi.Lapho i-graphite electrode isebenza ku-LF, yamanje izokwethulwa nge-graphite electrode esithandweni, futhi kuzoba nomthombo wokushisa okhiqizwa i-arc kagesi phakathi kokuphela kwe-electrode kanye nenkokhelo yesithando somlilo sokuncibilikisa.
(2) Ukukhiqiza i-silicon yensimbi ne-phosphorus ephuzi esithandweni somlilo esingaphansi kwamanzi
Enye i-carbon electrode enosayizi omkhulu (isb.700mm-1400mm) isetshenziselwa ukukhiqiza i-silicon yensimbi ne-phosphorus ephuzi esithandweni somlilo esingaphansi kwamanzi.Ingxenye engezansi ye-carbon electrode ingcwatshwa ekukhokhiseni, yenza i-arc kungqimba lokushaja, impahla izoncibilika ngamandla okushisa akhiqizwa ukumelana nokushaja.Isibonelo, cishe i-100kg ye-electrode ye-graphite isetshenziswa ngethani elingu-1 le-silicon yensimbi.
(3)Ngokukhiqiza i-corundum esithandweni sikagesi
(4)Isetshenziselwa ukucubungula imikhiqizo ye-graphite emise okukhethekile
I-electrode ye-graphite engenalutho nayo isetshenziselwa ukucubungula ama-graphite prod ahlukahlukene amise okwesipesheli
