Za graphite electrode joint

Mgwirizano wa electrode wa graphite uyenera kukhala wapamwamba kuposa thupi la electrode, choncho, mgwirizanowu uli ndi Coefficient yotsika yowonjezera kutentha ndi Coefficient yapamwamba yowonjezera kutentha kuposa electrode.

Kulumikizana kolimba kapena kotayirira pakati pa cholumikizira ndi dzenje la electrode screw kumatengera kusiyana kwa kukulitsa kwamafuta pakati pa cholumikizira ndi elekitirodi.Ngati mgwirizano wa axial Coefficient wa kukula kwa kutentha ukuposa electrode Coefficient of thermal expansion, kugwirizana kudzamasulidwa kapena kumasulidwa.Ngati Joint Meridional Coefficient ya kukula kwa matenthedwe idutsa kwambiri Coefficient of thermal expansion of the electrode screw hole, dzenje la electrode screw lidzakhala ndi nkhawa yakukulira.Kukula kosiyanasiyana kwamafuta ophatikizana ndi mabowo a electrode kumakhudzidwa ndi kugawa kwa kutentha kwachilengedwe (CTE) ndi gawo lazinthu ziwiri za graphite, ndipo kutentha uku ndi ntchito ya kuchuluka kwa zothina.Ngati mawonekedwe kukhudzana kukana ndi mkulu pa chiyambi, izi ndi chifukwa cha kukhudzana pamwamba ndi laimu ufa (fumbi), mapeto kuwonongeka, kugwirizana zoipa, kapena chifukwa cha zolakwika processing, amene adzapanga olowa kudzera kwambiri panopa, chifukwa kutenthedwa kwa cholumikizira, kupanikizika kwa mawonekedwe pamgwirizano kumadalira kuthamanga kwapakati pakati pa zigawo ziwirizi, koma Coefficient of thermal expansion ndi chinthu chomwe sichiyenera kunyalanyazidwa.

Pogwiritsira ntchito, kutentha kwa olowa nthawi zonse kumakhala kokwera kuposa kwa electrode pamalo omwewo opingasa.Ndi kuwonjezeka kwa kutentha, ma elekitirodi ndi olowa nawo zimapanga kukula kwa mzere.Kaya ma elekitirodi ndi olowa zikugwirizana kapena ayi nthawi zambiri zimatengera ngati chiwonjezeko chowonjezera cha ma elekitirodi chikugwirizana kapena ayi.

Ngakhale kulibe chinthu changwiro padziko lapansi, kampani ya Hexi carbon imayesetsa kwambiri kuti iganizire zinthu zosiyanasiyana popanga ma graphite electrode joints, kuti ikwaniritse ungwiro momwe ingathere ndikuwongolera khalidwe lazinthu momwe zingathere.
