I-graphite ingashintsha kanjani ithusi njenge-electrode? Kwabiwe nguAmandla aphezulu emishini ye-Graphite Electrode China.
Ngawo-1960, ithusi lalisetshenziswa kabanzi njengezinto ze-electrode, izinga lokusebenzisa libalelwa ku-90% kanye negraphite cishe ngo-10%. Ngekhulu lama-21, abasebenzisi abaningi ngokwengeziwe baqala ukukhetha i-graphite njengento ye-electrode. EYurophu, ngaphezu kwe-90% yezinto ze-electrode ziyi-graphite. I-Copper, uma iyingxenye ye-electrode evelele, 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 ngama-degree angu-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: ubukhulu be-graphite buyi-1/5 kuphela yethusi, enganciphisa 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 ka-C akuwoyela wenhlansi abole, okubuye kube ifilimu evikelayo ebusweni be-electrode yegraphite, kunxephezele 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 ngokuzenzakalelayo
(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 yokwenyuka kwentengo yethusi eminyakeni yamuva nje, intengo ye-isotropic graphite iphansi kuneyethusi. Ngaphansi kwevolumu efanayo, intengo yemikhiqizo ye-graphite evamile ye-toyo carbon ingama-30% ~ 60% ephansi kuneyethusi, futhi intengo izinzile, ukuguquguquka kwentengo yesikhashana kuncane kakhulu.
Ngenxa yale nzuzo engenakuqhathaniswa, i-graphite ishintshile kancane kancane ithusi njengento ekhethwayo ye-electrode ye-EDM.
