Sezvatinoziva tese, graphite ine hunhu hwemhando yepamusoro izvo zvimwe zvinhu zvesimbi hazvigone kutsiva. Sezvinhu zvinosarudzwa, graphite electrode zvinhu zvinowanzova nezvakawanda zvinokanganisa maitiro mukusarudzwa chaiko kwezvinhu. Kune akawanda mabhesi ekusarudza graphite electrode zvinhu, asi pane mana makuru maitiro:
Kune zvishandiso zvine avhareji saizi yechikamu, kusimba uye kuoma kwezvinhu zvine yakaderera resistivity zvakare yakadzikira zvishoma pane iyo ine yakakwirira resistivity. Kureva kuti, kukurumidza kubuda uye kurasikirwa kuchave kwakasiyana. Naizvozvo, iyo intrinsic resistivity ye graphite electrode zvinhu yakakosha kwazvo pakushandisa inoshanda. Kusarudzwa kwezvinhu zve electrode kunoenderana zvakananga nemhedzisiro yekubuda. Kusvika pamwero mukuru, kusarudzwa kwezvinhu zvinogadzirisa mamiriro ekupedzisira ekuburitsa kumhanya, machining akarurama uye pamusoro roughness.
Muindasitiri yakasarudzika yegraphite, iyo yakajairika kuomarara yekuyedza chiyero ndiyo Shore kuomarara nzira yekuyedza, iyo yekuyedza musimboti wakasiyana neiyo yesimbi. Kunyangwe mukunzwisisa kwedu kusinganzwisisike kwegraphite, inowanzoonekwa sechinhu chakapfava. Asi iyo chaiyo bvunzo data uye mashandisiro anoratidza kuti kuoma kwegraphite kwakakwira kupfuura iyo yesimbi zvinhu. Nekuda kweiyo yakaturikidzana chimiro chegraphite, ine yakanakisa yekucheka maitiro mukucheka maitiro. Simba rekucheka rinongosvika 1/3 yemhangura, uye iyo yakagadzirwa nemichina iri nyore kubata.
Nekudaro, nekuda kwekuoma kwayo kwepamusoro, chimbo chinopfeka chichava chikuru zvishoma pane icho chesimbi yekucheka maturusi mukucheka. Panguva imwecheteyo, zvinhu zvine kuoma kwepamusoro zvine kudzora kwakanakisa kwekubuda kurasikirwa. Naizvozvo, iyo Shore kuomarara kwegraphite electrode zvinhu zvakare imwe yemaitiro ekusarudza e graphite electrode zvinhu.
Ipapo kune kuchinjika kusimba kwegraphite electrode zvinhu. Simba rekushanduka-shanduka re graphite electrode zvinhu ndiko kuratidzwa kwakananga kwesimba rezvinhu, kuratidza kuwirirana kwemukati wemukati wezvigadzirwa. Izvo zvinhu zvine simba rakakwirira zvine zvakanakira discharge wear resistance. Kune electrode nehupamhi hwepamusoro, zvinhu zvine simba riri nani zvinofanira kusarudzwa sezvinobvira.
Pakupedzisira, avhareji yechidimbu dhayamita ye graphite electrode zvinhu, avhareji chidimbu dhayamita ye graphite electrode zvinhu zvinokanganisa zvakananga mamiriro ekubuda kwezvinhu. Iyo diki yeavhareji saizi yechikamu, iyo yakawanda yunifomu yekubuda, iyo yakanyanya kugadzikana mamiriro ekubuda uye zvirinani kunaka kwepamusoro. Iyo yakakura saizi yechikamu, inokurumidza kukurumidza kubuda uye kudiki kurasikirwa kwekukasha. Chikonzero chikuru ndechekuti simba rekuburitsa rinosiyana neazvino kusimba panguva yekubuda. Nekudaro, iyo yepamusoro pekupedzisira mushure mekubuda inosiyana nekuchinja kwezvikamu.
Graphite electrodes inogona kuve yekutanga sarudzo yezvinhu muindasitiri. Ndizvo chaizvo nokuti magirafu emagetsi ane mabhenefiti asina kunaka ayo akakosha ekusarudza maitiro emagraphite electrodes uye kusarudzwa kwemapeya akakodzera emagraphite electrode ndiyo kiyi.
