Ingayenza njani igraphite endaweni yobhedu njenge electrode?Yabelwe nguAmandla omatshini aphezulu eGraphite Electrode yaseTshayina.
Ngeminyaka yoo-1960, ubhedu lwalusetyenziswa kakhulu njengesixhobo se-electrode, izinga lokusetyenziswa libalelwa malunga ne-90% kunye negraphite kuphela malunga ne-10%.Ngenkulungwane yama-21, abasebenzisi abaninzi nangakumbi baqala ukukhetha igraphite njengesixhobo sombane.EYurophu, ngaphezu kwe-90% yezinto ze-electrode yigraphite.Ubhedu, xa sele buyinto elawulayo ye-electrode, sele iphantse yaphulukana nomphetho wayo phezu 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 obuphezulu bubangela ukuba iiathom ze-C ezikwintlantsi zibole, nto leyo eyenza ifilimu ekhuselayo kumphezulu we-electrode yegraphite, ihlawule 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 yethusi ngokuthe ngcembe njengento ekhethiweyo ye-EDM electrode.
