Kunezizathu eziningi zokukhetha izinto ze-graphite electrode, kodwa kunezindlela ezine eziyinhloko:
1. Ububanzi obumaphakathi bezinhlayiya zezinto
Ububanzi obumaphakathi bezinhlayiya zezinto buthinta ngqo isimo sokukhishwa kwezinto.
Uma usayizi wezinhlayiya ojwayelekile wezinto zokwakha uncane, kulapho ukukhishwa kwezinto zokwakha kufana khona, ukukhishwa kwazo kuzinze kakhulu, futhi ikhwalithi yobuso iba ngcono.
Ukuze uthole izikhunta ezibumbayo nezisebenzisa ugesi ezinezidingo eziphansi zobuso nokunemba, ngokuvamile kunconywa ukusebenzisa izinhlayiya eziqinile, njenge-ISEM-3, njll.; ukuze uthole izikhunta ze-elekthronikhi ezinezidingo eziphezulu zobuso nokunemba, kunconywa ukusebenzisa izinto ezinosayizi wezinhlayiya omaphakathi ongaphansi kuka-4μm.
Ukuqinisekisa ukunemba kanye nokuphela kobuso besikhunta esicutshunguliwe.
Uma usayizi wezinhlayiya ezimaphakathi zezinto ezincane, ukulahleka kwezinto ezincane, futhi amandla phakathi kwamaqembu e-ion aba maningi.
Isibonelo, i-ISEM-7 ivame ukunconywa ngezikhunta ezisebenzisa udayi kanye nezikhunta zokubumba ngokunemba. Kodwa-ke, uma amakhasimende enezidingo zokunemba okuphezulu kakhulu, kunconywa ukusebenzisa izinto ze-TTK-50 noma ze-ISO-63 ukuqinisekisa ukulahleka okuncane kwezinto.
Qinisekisa ukunemba kanye nobulukhuni bomphezulu wesikhunta.
Ngesikhathi esifanayo, lapho izinhlayiya zikhulu, isivinini sokukhipha sishesha futhi ukulahlekelwa komshini onzima kuncane.
Isizathu esiyinhloko ukuthi amandla amanje enqubo yokukhipha ahlukile, okuholela emandleni ahlukene okukhipha.
Kodwa ukuphela kobuso ngemva kokukhishwa kuyashintsha nokushintsha kwezinhlayiya.
2. Amandla okugobeka kwezinto
Amandla okuguquguquka kwezinto ezibonakalayo abonisa ngqo amandla ezinto ezibonakalayo, okubonisa ukuqina kwesakhiwo sangaphakathi sezinto ezibonakalayo.
Izinto eziqinile kakhulu zisebenza kahle kakhulu ekumelaneni nokukhishwa. Kuma-electrode anezidingo zokunemba okuphezulu, zama ukukhetha izinto eziqinile kangcono.
Isibonelo: I-TTK-4 ingahlangabezana nezidingo zezikhunta ezijwayelekile ze-elekthronikhi, kodwa kwezinye izikhunta ze-elekthronikhi ezinezidingo ezikhethekile zokunemba, ungasebenzisa usayizi ofanayo wezinhlayiya kodwa izinto zamandla aphezulu kancane i-TTK-5.
3. Ukuqina kogu lolwandle lwezinto
Ekuqondeni okungaphansi kwengqondo kwe-graphite, i-graphite ngokuvamile ibhekwa njengento ethambile.
Kodwa-ke, idatha yangempela yokuhlola kanye nezimo zokusetshenziswa zibonisa ukuthi ubulukhuni be-graphite buphakeme kunobezinto zensimbi.
Embonini ye-graphite ekhethekile, indinganiso yokuhlola ubulukhuni yendawo yonke yindlela yokulinganisa ubulukhuni be-Shore, futhi isimiso sayo sokuhlola sihlukile kwesezinsimbi.
Ngenxa yesakhiwo se-graphite esinezingqimba, sisebenza kahle kakhulu ekusikeni ngesikhathi senqubo yokusika. Amandla okusika angaba yi-1/3 kuphela yalawo ezinto zethusi, futhi indawo ngemuva komshini kulula ukuyiphatha.
Kodwa-ke, ngenxa yobulukhuni bayo obuphezulu, ukuguguleka kwamathuluzi ngesikhathi sokusika kuzoba kukhulu kancane kunokwamathuluzi okusika insimbi.
Ngesikhathi esifanayo, izinto ezinobulukhuni obuphezulu zilawula kangcono ukulahleka kokukhipha.
Ohlelweni lwethu lwezinto ze-EDM, kunezinto ezimbili ongakhetha kuzo zezinto ezinobukhulu obufanayo bezinhlayiya ezisetshenziswa kaningi, enye enobunzima obukhulu kanti enye enobunzima obuphansi ukuhlangabezana nezidingo zamakhasimende anezidingo ezahlukene.
isidingo.
Isibonelo: izinto ezinosayizi wezinhlayiya omaphakathi ongu-5μm zifaka phakathi i-ISO-63 ne-TTK-50; izinto ezinosayizi wezinhlayiya omaphakathi ongu-4μm zifaka phakathi i-TTK-4 ne-TTK-5; izinto ezinosayizi wezinhlayiya omaphakathi ongu-2μm zifaka phakathi i-TTK-8 ne-TTK-9.
Ngokuyinhloko kucatshangelwa ukukhetha kwezinhlobo ezahlukene zamakhasimende ekukhishweni nasekufakweni kukagesi.
4. Ukumelana okungaphakathi kwezinto
Ngokwezibalo zenkampani yethu mayelana nezici zezinto zokwakha, uma izinhlayiya ezijwayelekile zezinto zifana, isivinini sokukhipha esinokumelana okuphezulu sizohamba kancane kunokumelana okuphansi.
Ezintweni ezinobukhulu obufanayo bezinhlayiya, izinto ezinokumelana okuphansi zizoba namandla nobunzima obuphansi ngokufanayo kunezinto ezinokumelana okuphezulu.
Okusho ukuthi, ijubane lokukhipha kanye nokulahlekelwa kuzohluka.
Ngakho-ke, kubaluleke kakhulu ukukhetha izinto zokwakha ngokwezidingo zangempela zokusetshenziswa.
Ngenxa yokubaluleka kwe-powder metallurgy, ipharamitha ngayinye yeqoqo ngalinye lezinto inobubanzi obuthile bokuguquguquka kwenani layo elimele.
Kodwa-ke, imiphumela yokukhishwa kwezinto ze-graphite zebanga elifanayo ifana kakhulu, futhi umehluko emiphumeleni yokusetshenziswa ngenxa yemingcele ehlukahlukene mncane kakhulu.
Ukukhethwa kwezinto ze-electrode kuhlobene ngqo nomthelela wokukhishwa. Ngokwezinga elikhulu, ukuthi ukukhethwa kwezinto kufanele yini kunquma isimo sokugcina sejubane lokukhishwa, ukunemba komshini kanye nobulukhuni bomphezulu.
Lezi zinhlobo ezine zedatha zimele ukusebenza okuyinhloko kokukhishwa kwezinto futhi zinquma ngqo ukusebenza kwezinto.
