Ama-electrode e-graphiteziyizingxenye ezibalulekile ekusebenzeni kwezithando ze-arc, ezidlala indima ebalulekile ezinqubweni ezihlukahlukene zezimboni.
Ama-electrode e-graphite enziwa ngokuyinhloko ngohlobo lwekhabhoni ebizwa ngokuthi i-graphite, okuwuhlobo lwekristalu lwe-element carbon.I-graphite inezinto ezihlukile eziyenza ilungele ukusetshenziswa kuma-electrode, njengokuhamba kwawo okuphezulu kagesi, ukumelana okuphezulu nokushisa namakhemikhali, kanye ne-coefficient ephansi yokwanda okushisayo.Lezi zakhiwo zivumela ama-electrode e-graphite ukuthi asebenze kahle kakhulu ekusetshenzisweni kwesithando somlilo we-arc.
IInqubo yokukhiqiza ama-graphite electrodekuhilela izinyathelo ezimbalwa.Iqala ngokukhethwa kwezinto ezisezingeni eliphezulu ze-graphite, ezibuye zigaywe bese zixutshwa ne-binder material, njenge-coal tar pitch noma i-petroleum coke.Le ngxube ibe isibunjwa ibe yifomu le-electrode elifunekayo kusetshenziswa inqubo yokubumba.Ngemuva kokubunjwa, ama-electrode angaphansi kwenqubo yokubhaka ukuze asuse i-binder futhi aqhubeke nokuqinisa isakhiwo sekhabhoni.Lokhu kulandelwa inqubo ye-graphitization, ehlanganisa ukushisisa ama-electrode emazingeni okushisa acishe abe ngu-3000 degrees Celsius ukuze awaguqule abe igraphite.Ekugcineni, ama-electrode enza uchungechunge lwezivivinyo zokulawula ikhwalithi ukuze kuqinisekiswe ukusebenza kwawo nokwethembeka.
Ama-electrode e-graphite athola ukusetshenziswa okubanzi ezinqubweni ezihlukahlukene zezimboni, ikakhulukazi ezithandweni zikagesi ze-arc.Lezi ziko zisetshenziselwa ukukhiqizwa kwensimbi, lapho ama-electrode e-graphite esebenza njengezinto zokuqhuba ukukhiqiza nokugcina i-arc kagesi, encibilikisa izinto zokusetshenziswa futhi ivumela ukwakheka kwensimbi encibilikisiwe.Ukwengeza, ama-electrode e-graphite asetshenziswa kwezinye izinqubo ze-metallurgical ezifana nokukhiqizwa kwama-ferroalloys, i-silicon metal, ne-calcium carbide.
Ukubaluleka kwama-electrode e-graphite ezilungiselelweni zezimboni akukwazi ukweqiwa.I-thermal conductivity yabo ephezulu ivumela ukudluliswa kokushisa okuphumelelayo, okuvumela ukuncibilika ngokushesha nakakhudlwana kwezinto ezisetshenziswayo kuma-arc furnaces.Ama-electrode e-graphite aphinde abonise ukumelana okuhle kakhulu nokushaqeka okushisayo, ukuwavimbela ekuqhekekeni noma ekuphukeni ngaphansi kwezimo zokushisa ezinzima.Lokhu kuqina kuqinisekisa impilo ye-electrode ende futhi kunciphisa isikhathi sokuphumula kanye nezindleko zokunakekela.
Ngaphezu kwalokho, i-graphite electrode conductivity kagesikungesinye isici esibalulekile ekubalulekeni kwabo kwezimboni.I-conductivity ephezulu yenza ukuhamba kahle kukagesi ngokusebenzisa ama-electrode, okuholela ku-arc ezinzile futhi engaguquki phakathi nenqubo yokuncibilika.Lokhu kuqinisekisa ukusatshalaliswa okufanayo nokulawulwa kokushisa, okuholela ekuthuthukisweni kwekhwalithi yensimbi nokuvumelana.
Ubukhulu nekhwalithi yama-electrode e-graphite kuba nomthelela omkhulu ekusebenzeni kwawo ekusebenzeni kwesithando somlilo se-arc.Ubukhulu bama-electrode, njengobubanzi nobude bawo, ziyahlukahluka kuye ngomklamo othile wesithando somlilo kanye nezidingo zokukhiqiza.Abakhiqizi bakhiqiza izinhlobonhlobo zamasayizi ama-electrode ukuze kuhlangatshezwane nezinhlobo ezahlukene zesithando somlilo namandla.
Abakhiqizi be-graphite electrodeidlala indima ebalulekile ekuhlinzekeni lezi zingxenye ezibalulekile ezimbonini emhlabeni wonke.Laba bakhiqizi kumele bahambisane nezinyathelo eziqinile zokulawula ikhwalithi ukuze kuqinisekiswe ukukhiqizwa kwama-electrode ahlangabezana namazinga embonini.Ukulawulwa kwekhwalithi kuhlanganisa ukuhlolwa kwezakhiwo ezibonakalayo, njengokuminyana nokunwebeka kokushisa, kanye nezakhiwo zikagesi, ezifana nokumelana nokumelana nogesi okuthile.Ngokugcina izindinganiso zekhwalithi ezingaguquki, abakhiqizi be-graphite electrode bafaka isandla ekusebenzeni kahle okuphelele nasekukhiqizeni imisebenzi yesithando somlilo se-arc.
Sengiphetha, ama-electrode e-graphite abalulekile ekusebenzeni kwezithando zama-arc futhi adlala indima ebalulekile ezinqubweni eziningi zezimboni.Izakhiwo zabo eziyingqayizivele, ezifana nokuhamba kukagesi okuphezulu, ukumelana nokushisa, nokuqina, kubenza balungele ukusetshenziswa kulezi zinhlelo zokusebenza.Inqubo yokukhiqiza ama-electrode e-graphite ihilela ukukhethwa ngokucophelela kwezinto ze-graphite zekhwalithi ephezulu, okulandelwa uchungechunge lwezinyathelo ezifana nokuxuba, ukubumba, ukubhaka, kanye ne-graphitization.Ama-electrode e-graphite athola izinhlelo zokusebenza ekukhiqizeni insimbi kanye nezinqubo ezihlukahlukene ze-metallurgical.Ukubaluleka kwabo kukwazi ukudlulisa kahle ukushisa, ukumelana nokushaqeka kwe-thermal, nokuhlinzeka nge-conductivity kagesi ezinzile.Sekukonke, abakhiqizi be-electrode be-graphite badlala indima ebalulekile ekuhlinzekeni ama-electrode ekhwalithi ephezulu kanye nokuqinisekisa ukusebenza kahle nokuthembeka kwemisebenzi yezimboni.
XHUMANA NATHIUkuthola ULWAZI OLUYIQINISO MAYELANA NE-GRAPHITE ELECTRODE.
