Ukusetshenziswa nokusebenza kwe-graphite electrode

Okokuqala, ukuhlukaniswa kwe-graphite electrode

I-electrode yegraphite ihlukaniswe: amandla ajwayelekile e-graphite electrode (RP); Amandla aphezulu we-graphite electrode (HP); I-ultra-high power graphite electrode (UHP).

Okwesibili, ukusetshenziswa kwe-graphite electrode

1. Isetshenziselwa ukwenza insimbi yesithando se-arc kagesi

I-graphite electrode material isetshenziswa kakhulu ekwenzeni insimbi yesithando somlilo kagesi. Ukwenziwa kwensimbi yesithando somlilo ukusebenzisa i-graphite electrode esithandweni ukwethula ukusebenza kwamanje, amandla amanje angaphansi kwe-electrode angaba ngale ndawo yegesi ukukhiqiza umthelela wokukhishwa kwe-arc, kusetshenziswa ukushisa okukhiqizwa i-arc ekuncibilikiseni. . Ubukhulu bamandla kagesi, afakwe ama-electrode e-graphite anama-diameter ahlukene, angasetshenziswa ngokuqhubekayo, ngokumelene nokuxhumana phakathi kwama-electrode joints electrode. I-graphite esetshenziswa ekwenzeni insimbi njenge-electrode material ibalelwa ku-70-80% yenani eliphelele le-graphite e-China.

I-2.Isetshenziselwa isithando somlilo esishisayo samaminerali

Isetshenziselwa ukukhiqizwa kwe-ferroalloy yesithando somlilo, i-silicon ehlanzekile, i-phosphorus ephuzi, i-calcium carbide ne-matte, ebonakala ngengxenye engezansi ye-electrode conductive engcwatshwe ekukhokhiseni, ngakho-ke ngaphezu kwepuleti kagesi kanye ne-arc kagesi phakathi kokushaja. ukukhiqiza ukushisa, i-current through the charge resistance iphinde ikhiqize ukushisa.

3.Okwezithando zomlilo

Enqubweni yokukhiqiza, isithando somlilo se-graphitization semikhiqizo ye-graphite yezinto ezibonakalayo, isithando somlilo sengilazi encibilikayo kanye nesithando somlilo sikagesi se-silicon carbide yiziko zokumelana. Ukuphathwa kwezinto ezibonakalayo esithandweni akuyona nje ukumelana nokushisa, kodwa futhi into okufanele ishiswe.

4.Hot die casting die kanye ne-vacuum heater yomlilo neminye imikhiqizo ekhethekile

Kumele futhi kuqashelwe ukuthi ekuhlanganiseni i-graphite electrode, isikhunta se-graphite kanye ne-graphite crucible 3 izinhlobo zezinto ezihlanganisiwe zokushisa okuphezulu, izinto ezintathu ze-graphite ekushiseni okuphezulu, i-graphite kulula ukuyi-oxidize ukusabela komlilo, ngakho-ke ebusweni be-carbon layer of the material. , thuthukisa ukwakheka kwe-graphite void okuxekethile.
