Njira Yopangira The Graphite Electrode
Graphite elekitirodi ndi mtundu wa kutentha kugonjetsedwa ndi graphite conductive zakuthupi opangidwa pogwiritsa ntchito petroleum coke, singano coke monga akaphatikiza, malasha phula monga binder, pambuyo angapo njira monga kusakaniza, akamaumba, Kukuwotcha, kuviika, graphitization ndi processing makina.
Njira zazikulu zopangira ma electrode a graphite ndi awa:
(1) Kukalala.Mafuta a coke kapena asphalt coke ayenera kupangidwa, ndipo kutentha kwa calcination kuyenera kufika 1300 ℃, kotero kuti kuchotsa kwathunthu zinthu zosakhazikika zomwe zili mu carbon raw materials, ndikuwongolera kachulukidwe woona, mphamvu zamakina ndi mphamvu zamagetsi za coke.
(2) kuphwanya, kuyesa, ndi zosakaniza.The calcined carbon yaiwisi yaiwisi anathyoledwa ndi kuwonetseredwa mu akaphatikiza particles za kukula kwapadera, mbali ya coke ndi pansi ufa wabwino, ndi youma osakaniza ndi moyikira molingana chilinganizo.
(3) Sakanizani.Mu Kutentha boma, kachulukidwe youma osakaniza zosiyanasiyana particles ndi kachulukidwe binder, wothira ndi kneaded kuti lithe pulasitiki phala.
(4) akamaumba, pansi pa zochita za kuthamanga kunja (extrusion kupanga) kapena pansi pa zochita za mkulu pafupipafupi kugwedera (kugwedera kupanga) akanikizire phala mu mawonekedwe enaake ndi mkulu osalimba yaiwisi electrode (billet).
(5) Kuphika.Elekitirodi yaiwisi imayikidwa mu ng'anjo yapadera yowotcha, ndipo ufa wa coke wazitsulo umadzazidwa ndikuphimba ndi electrode yaiwisi.Pakutentha kwambiri kwa cholumikizira cha pafupifupi 1250 ℃, chowotcha cha carbon electrode chimapangidwa.
(6) Wopanda chilema.Pofuna kukonza kachulukidwe ndi mphamvu zamakina amagetsi amagetsi, ma elekitirodi owotcha amalowetsedwa mu zida zamagetsi apamwamba, ndipo phula lamadzimadzi loviika limakanikizidwa mu dzenje la mpweya wa elekitirodi.Pambuyo pa kumizidwa, kuwotcha kuyenera kuchitika kamodzi.Malinga ndi zomwe zimafunikira pakugwirira ntchito kwa chinthucho, nthawi zina kuyimitsidwa ndi kuwotcha kwachiwiri kuyenera kubwerezedwa nthawi 23.
(7) graphitization.Mpweya wa kaboni wophika umayikidwa mu ng'anjo ya graphitization, yokutidwa ndi zinthu zotsekemera.Pogwiritsa ntchito njira yowotchera yopangira magetsi mwachindunji kuti ipange kutentha kwambiri, ma elekitirodi a kaboni amasinthidwa kukhala ma elekitirodi a graphite okhala ndi graphite crystal structure pa kutentha kwakukulu kwa 2200 ~ 3000 ℃.
(8) makina.Malinga ndi zofunika ntchito, graphite elekitirodi akusowekapo pamwamba kutembenuka, lathyathyathya mapeto pamwamba ndi wononga mabowo pokonza kugwirizana, ndi olowa kuti kugwirizana.
(9) Elekitirodi ya graphite idzayikidwa bwino pambuyo poyang'ana ndikutumizidwa kwa wogwiritsa ntchito.
