Kuki grafite ishobora gusimbuza umuringa nka electrode?

Nigute grafite ishobora gusimbuza umuringa nka electrode? Bisangiwe naImbaraga zikomeye za Graphite Electrode Ubushinwa.

Mu myaka ya za 1960, umuringa wakoreshwaga cyane nk'ibikoresho bya electrode, igipimo cyo gukoresha kingana na 90% na grafite hafi 10%. Mu kinyejana cya 21, abakoresha benshi kandi benshi batangiye guhitamo grafite nkibikoresho bya electrode. Mu Burayi, ibice birenga 90% bya electrode ni grafite. Umuringa, iyo ibikoresho bya electrode byiganje, byatakaje hafi ya grafite. Niki cyateye iri hinduka rikomeye? Birumvikana, hari ibyiza byinshi bya grafite electrode.

(1) umuvuduko wihuse wo gutunganya: muri rusange, umuvuduko wo gutunganya imashini yaGraphite Electrode yo kugurishairashobora kwihuta inshuro 2 ~ 5 kurenza iz'umuringa; Nyamara, edm yihuta inshuro 2 ~ 3 kurenza umuringa, kandi ibikoresho ntibikunda guhinduka. Ingingo yoroshye yumuringa igera kuri dogere 1000, kandi biroroshye guhindurwa nubushyuhe. Graphite sublimation ubushyuhe bwa dogere 3650; Coefficient yo kwagura ubushyuhe ni 1/30 cyumuringa gusa.

. Birenzeho gukoreshwa muburyo bunini.

(3) gusohora ibicuruzwa ni bito; Kubera ko amavuta ya spark nayo arimo atome C, mugihe cyo gutunganya ibicuruzwa, ubushyuhe bwinshi butera C atom mumavuta ya spark kubora, nayo ikora firime ikingira hejuru ya electrode ya grafite, ikishyura igihombo cya electrode ya grafite. .

(4) nta burrs; Nyuma ya electrode y'umuringa itunganijwe, igomba gutunganywa intoki kugirango ikureho burrs, mugihe igishushanyo cyakozwe naGraphite Electrode urugandanta burrs, izigama ibiciro byinshi kandi byoroshya gukora umusaruro

(5) igishushanyo cyoroshye gusya no gusya; Kubera ko grafite ifite kimwe cya gatanu cyokugabanya umuringa, biroroshye gusya no gusiga intoki

(6) igiciro gito cyibiciro nigiciro gihamye; Kubera izamuka ryibiciro byumuringa mumyaka yashize, igiciro cya isotropic grafite kiri munsi yicy'umuringa. Mubunini bumwe, igiciro cyibicuruzwa rusange bya grafite ya toyo karubone iri munsi ya 30% ~ 60% ugereranije niy'umuringa, kandi igiciro kirahagaze neza, ihindagurika ryibiciro byigihe gito ni rito cyane.

Kubera iyi nyungu ntagereranywa, grafite yagiye isimbuza umuringa buhoro buhoro nkibikoresho byatoranijwe kuri EDM electrode.
