Ingayenza njani igraphite endaweni yobhedu njenge electrode? Yabelwe nguAmandla omatshini aphezulu eGraphite Electrode yaseTshayina.
Ngeminyaka yoo-1960, ubhedu lwalusetyenziswa kakhulu njengesixhobo se-electrode, kwaye izinga lokusetyenziswa libalelwa malunga ne-90% kunye negraphite kuphela malunga ne-10%. Ngenkulungwane yama-21, abasebenzisi abaninzi nangakumbi baqala ukukhetha igraphite njengesixhobo se-electrode. EYurophu, ngaphezu kwe-90% yezinto ze-electrode yigraphite. Ikhopha, xa sele iyinto elawulayo ye-electrode, iphantse yaphulukana nomphetho wayo ngaphezulu kwegraphite. Yintoni eyabangela olu tshintsho? Kakade ke, kukho iingenelo ezininzi ze-graphite electrode.
(1) isantya processing ngokukhawuleza: ngokubanzi, isantya processing oomatshini yeI-Graphite Electrode iyathengiswainokuba 2 ~ 5 amaxesha ngokukhawuleza kunobhedu; Nangona kunjalo, i-edm i-2 ~ 3 amaxesha ngokukhawuleza kunobhedu, kwaye izinto eziphathekayo zincinci kwi-deformation. Indawo yokuthambisa yobhedu imalunga ne-1000 degrees, kwaye kulula ukukhubaza bubushushu. iqondo lobushushu be-Graphite sublimation ye-3650 degrees; I-coefficient yokwandiswa kwe-thermal kuphela i-1/30 yobhedu.
(2) ubunzima obulula: ubuninzi begraphite yi-1/5 kuphela yobhedu, enokunciphisa ngokufanelekileyo umthwalo wesixhobo somatshini (EDM) xa i-electrodes enkulu icutshungulwa ngokukhutshwa; Kufanelekile ngakumbi ukusetyenziswa kwesikhunta esikhulu.
(3) ukukhupha ukusetyenziswa kuncinci; Ekubeni ioli yentlantsi ikwaqulethe iiathom ze-C, ngexesha lokukhutshwa kwamanzi, ubushushu obuphakamileyo bubangela ukuba iiathom ze-C ezikwi-oyile yentlantsi zibole, nto leyo eyenza ifilimu ekhuselayo kumphezulu we-electrode yegraphite, ihlawulela ukulahleka kwe-electrode yegraphite. .
(4) akukho burrs; Emva kokuba i-electrode yobhedu icutshungulwe, kufuneka ilungiswe ngesandla ukususa i-burrs, ngelixa igraphite icutshungulwa.Umzi-mveliso weGraphite Electrodengaphandle kwe-burrs, egcina iindleko ezininzi kwaye yenza kube lula ukwenza imveliso ngokuzenzekelayo
(5) igraphite kulula ukuyigaya nokupholisha; Ekubeni i-graphite inesiqingatha sesihlanu kuphela sokumelana nokusika ubhedu, kulula ukugaya kunye nokupolisha ngesandla
(6) ixabiso lezinto eziphathekayo kunye nexabiso elizinzile; Ngenxa yokunyuka kwexabiso lobhedu kwiminyaka yakutshanje, ixabiso legraphite ye-isotropic liphantsi kunelobhedu. Ngaphantsi komthamo ofanayo, ixabiso leemveliso zegraphite ngokubanzi ze-toyo carbon yi-30% ~ 60% ephantsi kunobhedu, kwaye ixabiso lizinzile, ukuguquguquka kwexabiso lexesha elifutshane kuncinci kakhulu.
Ngenxa yolu ncedo olungenakuqhathaniswa, igraphite ithathe indawo yobhedu njengento ekhethiweyo ye-EDM electrode.
