Eminyakeni yamuva nje, ngokusetshenziswa kabanzi kwezikhunta ze-graphite, inani lokusetshenziswa kwaminyaka yonke kwezikhunta embonini yemishini liphindwe kahlanu kunenani eliphelele lazo zonke izinhlobo zamathuluzi omshini, futhi ukulahlekelwa okukhulu kokushisa nakho kuphambene kakhulu nezinqubomgomo ezikhona zokonga amandla eShayina. Ukusetshenziswa okukhulu kwezikhunta akugcini nje ngokwandisa ngqo izindleko zamabhizinisi, kodwa futhi kuholela ekuvalweni kwemigqa yokukhiqiza njalo ngenxa yokufakwa kabusha kwezikhunta njalo, ekugcineni okubangela ukulahlekelwa okukhulu kwezomnotho.
Ngokusho kocwaningo, ngenxa yezinto zokusetshenziswa kwesikhunta kanye namanani amandla akhuphuke kakhulu kanye nezinye izizathu, inzuzo yemikhiqizo yemboni yesikhunta yehle ngonyaka odlule; Ukuze zisinde futhi zithuthuke, amabhizinisi amaningi ayazamukela
Ukushintsha izinto kusetshenziswa njengendlela enkulu yokuguqula nokuthuthukisa. Kuyaqondakala ukuthi izinkampani eziningi zethule izinto zokukhipha inhlansi ye-graphite, ekukhiqizweni kwesikhunta kudlala indima ebaluleke kakhulu. Uma kuqhathaniswa nesikhunta sethusi sendabuko, izinto ze-graphite zinezinzuzo zokunemba okuphezulu komshini kanye nomphumela omuhle wobuso, ikakhulukazi ekucutshungulweni kwesikhala sesikhunta sokunemba, udonga oluyinkimbinkimbi, oluncane, nezinto eziqinile eziphakeme zinenzuzo enkulu. Uma kuqhathaniswa nethusi, izinto ze-graphite zinezinzuzo ezifana nokusetshenziswa okuncane, isivinini sokukhipha okusheshayo, isisindo esincane kanye ne-coefficient encane yokukhulisa ukushisa, ngakho-ke i-electrode yethusi iye yaba yinto eyinhloko yezinto zokucubungula ukukhishwa. Ngokuphambene nalokho, izinto ze-graphite electrode zinezinzuzo eziyisithupha ezilandelayo:
1. Isivinini esisheshayo; Ukukhishwa kwe-graphite kushesha ngokuphindwe kabili kuya kathathu kunethusi, futhi izinto akulula ukuziguqula. Zinezinzuzo ezisobala ekucutshungulweni kwe-electrode encane eqinisiwe. Indawo yokuthambisa yethusi icishe ibe yi-1000 degrees, futhi kulula ukuyiguqula ngenxa yokushisa.
2. Isisindo esincane; Ubuningi be-graphite buyi-1/5 kuphela yobethusi. Uma i-electrode enkulu icutshungulwa ngokukhishwa, umthwalo wethuluzi lomshini (i-EDM) ungancishiswa ngempumelelo, okuyinto efaneleka kakhulu ekusetshenzisweni kwesikhunta esikhulu.
3. Ukumosheka okuncane; Njengoba uwoyela we-spark uqukethe ama-athomu e-C, izinga lokushisa eliphezulu libangela ukuthi ama-athomu e-C ku-spark oil abole ngesikhathi sokucubungula ukukhishwa, bese kwakheka ifilimu evikelayo ebusweni be-graphite electrode, ekhokhela ukulahleka kwe-graphite electrode.
4. Azikho izimbobo; Ngemva kokuba i-electrode yethusi isicutshunguliwe, izimbobo kudingeka zisuswe ngesandla. Kodwa-ke, azikho izimbobo ngemva kokuba i-graphite isicutshunguliwe, okungagcini nje ngokusindisa izindleko eziningi kanye namandla abasebenzi, kodwa futhi kwenza kube lula ukukhiqiza ngokuzenzakalelayo.
5. Ukupholisha okulula; Ngenxa yokuthi ukumelana kokusika kwe-graphite kuyingxenye eyodwa kwezinhlanu kuphela zethusi, kulula ukuyigaya nokuyipholisha ngesandla.
Vi. Izindleko eziphansi; Ngenxa yokwenyuka kwentengo yethusi eminyakeni yamuva nje, intengo ye-graphite kuzo zonke izici iphansi kuneyethusi. Ngaphansi komthamo ofanayo wobubanzi be-carbon yaseMpumalanga, intengo yemikhiqizo ye-graphite iphansi ngo-30% kuya ku-60% kuneyethusi, intengo izinzile, futhi ukuguquguquka kwentengo yesikhashana kuncane kakhulu. Njengoba ukongiwa kwamandla, ukuvikelwa kwemvelo kanye nokusebenza kahle kokucubungula kuba yinto egxile embonini yokukhiqiza, izinto ze-graphite electrode zizothatha indawo ye-electrode yethusi kancane kancane futhi zidlale indima ebalulekile ku-EDM. Ngokufanayo, emncintiswaneni okhulayo emakethe yesikhunta namuhla, ukusetshenziswa kobuchwepheshe bokucubungula obuthuthukisiwe ukuthuthukisa imikhiqizo yesikhunta esezingeni eliphezulu kuyindlela engcono kakhulu yamabhizinisi yokuwina imakethe namakhasimende.
