I-graphite ingashintsha kanjani ithusi njenge-electrode?Kwabiwe nguAmandla aphezulu emishini yeGraphite Electrode yaseChina.
Ngawo-1960, ithusi lalisetshenziswa kabanzi njengezinto ze-electrode, izinga lokusebenzisa lalibalelwa ku-90% kanye negraphite cishe ngo-10%.Ekhulwini lama-21, abasebenzisi abaningi ngokwengeziwe baqala ukukhetha i-graphite njengento ye-electrode.EYurophu, ngaphezu kwe-90% yezinto ze-electrode yi-graphite.I-Copper, lapho iyingxenye ye-electrode ebusayo, isicishe yalahlekelwa umkhawulo wayo phezu kwegraphite.Yini eyabangela lolu shintsho olukhulu?Yiqiniso, kunezinzuzo eziningi ze-graphite electrode.
(1) ngokushesha ukucutshungulwa isivinini: ngokuvamile, ijubane mechanical processingI-Graphite Electrode iyathengiswakungaba izikhathi ezi-2 ~ 5 ngokushesha kunezethusi;Kodwa-ke, i-edm ishesha izikhathi ezi-2 ~ 3 kunethusi, futhi izinto ezisetshenziswayo azijwayele ukuguqulwa.Indawo yokuthambisa yethusi icishe ibe ngamadigri ayi-1000, futhi kulula ukukhubazeka ngenxa yokushisa.Ukushisa kwe-graphite sublimation ye-3650 degrees;I-coefficient yokunwetshwa kwe-thermal ingu-1/30 kuphela wethusi.
(2) isisindo esilula: ukuminyana kwegraphite kungu-1/5 kuphela wethusi, okunganciphisa ngokuphumelelayo umthwalo wethuluzi lomshini (EDM) lapho ama-electrode amakhulu ecutshungulwa ngokukhipha;Okufanelekile kakhulu ukusetshenziswa kwesikhunta esikhulu.
(3) ukusetshenziswa kokukhishwa kuncane;Njengoba uwoyela wenhlansi uqukethe nama-athomu angu-C, phakathi nokucutshungulwa kokukhishwa koketshezi, izinga lokushisa eliphakeme libangela ukuba ama-athomu C akuwoyela wenhlansi abole, okubuye kube ifilimu evikelayo ebusweni be-electrode yegraphite, kunxeshezelwe ukulahleka kwe-electrode yegraphite. .
(4) awekho ama-burrs;Ngemuva kokuthi i-electrode yethusi isicutshungulwe, idinga ukusikwa ngesandla ukuze isuse ama-burrs, kuyilapho i-graphite icutshungulwaImboni ye-Graphite Electrodengaphandle kwama-burrs, okugcina izindleko eziningi futhi kwenza kube lula ukwenza ukukhiqiza kube lula
(5) kulula ukuyigaya nokupholisha i-graphite;Njengoba i-graphite inengxenye yesihlanu kuphela yokumelana nokusika yethusi, kulula ukuyigaya nokupholisha ngesandla
(6) izindleko zempahla eziphansi kanye nenani elizinzile;Ngenxa yokukhuphuka kwentengo yethusi eminyakeni yamuva, intengo ye-isotropic graphite iphansi kuneyethusi.Ngaphansi komthamo ofanayo, intengo yemikhiqizo ye-graphite evamile ye-toyo carbon ingama-30% ~ 60% ephansi kunaleyo yethusi, futhi intengo izinzile, ukushintshashintsha kwentengo yesikhashana kuncane kakhulu.
Ngenxa yale nzuzo engenakuqhathaniswa, i-graphite ishintshile kancane kancane ithusi njengento ekhethwayo ye-electrode ye-EDM.
