I-graphite ingayithatha kanjani indawo yethusi njenge-electrode?Amandla aphezulu omshini we-Graphite Electrode China.
Ngawo-1960, ithusi lalisetshenziswa kabanzi njengezinto ze-electrode, kanti izinga lokusetshenziswa lalilinganiselwa ku-90% kanti i-graphite yayicishe ibe yi-10%. Ekhulwini lama-21, abasebenzisi abaningi baqala ukukhetha i-graphite njengezinto ze-electrode. EYurophu, ngaphezu kuka-90% wezinto ze-electrode ziyi-graphite. Ithusi, eyake yaba yinto eyinhloko ye-electrode, selicishe lilahlekelwe umkhawulo walo ngaphezu kwe-graphite. Yini eyabangela lolu shintsho olukhulu? Yiqiniso, kunezinzuzo eziningi ze-graphite electrode.
(1) isivinini sokucubungula esisheshayo: ngokuvamile, isivinini sokucubungula ngomshiniI-Graphite Electrode iyathengiswakungaba ngokushesha okuphindwe kabili kuya kahlanu kunethusi; Kodwa-ke, i-edm ishesha ngokuphindwe kabili kuya kathathu kunethusi, futhi izinto azikwazi ukuguqulwa kakhulu. Indawo yokuthambisa yethusi icishe ibe ngama-degree ayi-1000, futhi kulula ukuyishintshashintsha ngokushisa. Izinga lokushisa le-Graphite sublimation lama-degree angu-3650; I-coefficient yokwanda kokushisa ingama-1/30 kuphela ethusi.
(2) isisindo esilula: ubuningi be-graphite buyi-1/5 kuphela yobuningi bethusi, okunganciphisa ngempumelelo umthwalo wethuluzi lomshini (i-EDM) lapho ama-electrode amakhulu ecutshungulwa ngokukhishwa; Kufaneleka kakhulu ukusetshenziswa kwesikhunta esikhulu.
(3) ukusetshenziswa kokukhipha kuncane; Njengoba uwoyela we-spark uqukethe nama-athomu e-C, ngesikhathi sokucubungula ukukhishwa, izinga lokushisa eliphezulu libangela ukuthi ama-athomu e-C ku-spark oil abole, okwenza ifilimu evikelayo ebusweni be-graphite electrode, okukhokhela ukulahlekelwa yi-graphite electrode.
(4) akukho ma-burrs; Ngemva kokuthi i-electrode yethusi isicutshunguliwe, idinga ukunqunywa ngesandla ukuze kususwe ama-burrs, kuyilapho i-graphite icutshungulwa yi-Ifektri yeGraphite Electrodengaphandle kwama-burrs, okusindisa izindleko eziningi futhi kwenza kube lula ukwenza ngokuzenzakalelayo ukukhiqiza
(5) i-graphite kulula ukuyigaya nokuyipholisha; Njengoba i-graphite inengxenye yesihlanu kuphela yokumelana nokusika njengethusi, kulula ukuyigaya nokuyipholisha ngesandla.
(6) izindleko zezinto eziphansi kanye nentengo ezinzile; Ngenxa yokwenyuka kwentengo yethusi eminyakeni yamuva nje, intengo ye-isotropic graphite iphansi kuneyethusi. Ngaphansi komthamo ofanayo, intengo yemikhiqizo ye-graphite ejwayelekile ye-toyo carbon iphansi ngo-30% ~ 60% kuneyethusi, futhi intengo izinzile kakhudlwana, ukuguquguquka kwentengo yesikhashana kuncane kakhulu.
Ngenxa yale nzuzo engenakuqhathaniswa, i-graphite iye yathatha indawo yethusi kancane kancane njengento ekhethwayo ye-electrode ye-EDM.
