Ma electrode a grafiti amatanthauza mafuta a coke, singano ya coke ngati zinthu zopangira, malasha phula la zomatira, pambuyo poyika zinthu zopangira calcined, kusweka, kusakaniza, kukanda, kupanga, calcination, impregnation, graphite ndi makina opangira ndipo amapangidwa ndi mtundu wa kukana kutentha kwambiri kwa zinthu zopangira graphite, wotchedwa graphite electrode yopangira (yomwe tsopano imatchedwa graphite electrode), kuti isiyanitse ndi graphite yachilengedwe monga kukonzekera zinthu zopangira graphite electrode yachilengedwe. Malinga ndi index yake yabwino, imatha kugawidwa m'ma electrode wamba a graphite, electrode ya graphite yamphamvu kwambiri ndi electrode ya graphite yamphamvu kwambiri.
Ma electrode amphamvu kwambiri a graphite amapangidwa ndi mafuta a coke (kapena singano yaing'ono), nthawi zina thupi la electrode limafunika kulowetsedwa, mphamvu zake zakuthupi ndi zamakanika zimakhala zapamwamba kuposa ma electrode wamba a graphite, monga kukana kochepa, zomwe zimapangitsa kuti magetsi azikhala ndi mphamvu zambiri.
Ma electrode amphamvu kwambiri a graphite amalola kugwiritsa ntchito ma electrode a graphite a 18 ~ 25A/cm2, omwe amagwiritsidwa ntchito kwambiri popanga chitsulo cha arc ng'anjo champhamvu kwambiri.
Kupanga zitsulo za ng'anjo yamagetsi ndi komwe kumagwiritsa ntchito kwambiri ma electrode a graphite. Kutulutsa kwa chitsulo cha eAF ku China kumaphatikizapo pafupifupi 18% ya kutulutsa kwa chitsulo chosaphikidwa, ndipo ma electrode a graphite omwe amagwiritsidwa ntchito popanga zitsulo amaimira 70% ~ 80% ya kuchuluka kwa ma electrode a graphite. Kupanga zitsulo za ng'anjo yamagetsi ndi kugwiritsa ntchito ma electrode a graphite mu ng'anjo yamagetsi, kugwiritsa ntchito magetsi ochulukirapo ndi mphamvu pakati pa arc yopangidwa ndi gwero la kutentha kwambiri mpaka kusungunula.
-arc ng'anjo imagwiritsidwa ntchito makamaka popanga phosphorous yachikasu ya mafakitale ndi silicon, ndi zina zotero, khalidwe lake ndi gawo lotsika la electrode yoyendetsa yomwe imayikidwa mu ng'anjo, arc imapangidwa mkati mwa wosanjikiza wazinthu, ndipo imagwiritsa ntchito ng'anjo yokha kuchokera ku kukana kwa mphamvu yotentha kupita ku ng'anjo yotentha, imodzi mwamagetsi apamwamba kwambiri omwe amafunikira -arc ng'anjo imafuna graphite electrode, monga silicon 1 t pakupanga mpaka kugwiritsa ntchito graphite electrode ndi pafupifupi 100 kg, Pafupifupi 40kg ya graphite electrode imafunika kuti ipange phosphorous yachikasu 1t.
Uvuni wa graphitization wopangira zinthu za graphite, uvuni wosungunuka wa galasi losungunuka ndi uvuni wamagetsi wopangira silicon carbide ndi wa uvuni wotsutsa. Zinthu zomwe zili mu uvuni ndi zotsutsana ndi kutentha komanso chinthu chotenthetsera. Nthawi zambiri, electrode ya graphite yoyendetsa imayikidwa mu khoma la uvuni kumapeto kwa uvuni wotsutsa, ndipo electrode ya graphite imagwiritsidwa ntchito kuti igwiritsidwe ntchito mosalekeza pano.
Ma electrode opanda kanthu a graphite amagwiritsidwanso ntchito pokonza zinthu zosiyanasiyana za graphite zophimbidwa ndi nkhungu, bwato ndi zotenthetsera ndi zinthu zina zapadera za graphite. Mwachitsanzo, mumakampani opanga magalasi a quartz, 10T ya graphite electrode billet imafunika pa 1T iliyonse ya chubu cha fuse chamagetsi; 100kg ya graphite electrode billet imafunika kuti pakhale njerwa ya quartz ya 1t.
Kuyambira kotala lachinayi la chaka cha 2016, ndi kukwezedwa kwa mfundo zosinthira mbali yoperekera zinthu mumakampani opanga zitsulo ndi zitsulo, kuthetsa chitsulo cha pansi mwadzidzidzi kwakhala chinthu chofunikira kwambiri pakuchotsa mphamvu zopangira zomwe zatsala pang'ono kutha. Pa Januware 10, 2017, wachiwiri kwa Mtsogoleri wa National Development and Reform Commission adati pamsonkhano wa 2017 Council wa CISA kuti mipiringidzo yonse ya pansi iyenera kuchotsedwa isanafike pa June 30, 2017. Mu 2017, mphamvu yonse ya eAF ku China inali pafupifupi matani 120 miliyoni, pomwe matani 86.6 miliyoni anali kupangidwa ndipo matani 15.6 miliyoni anali atachotsedwa. Pofika kumapeto kwa Okutobala 2017, mphamvu yopangira eAF inali pafupifupi matani 26.5 miliyoni, ndipo pafupifupi 30% inayambiranso. Chifukwa cha kuchepa kwa mphamvu ya ng'anjo yapakatikati, chitsulo chamagetsi cha ng'anjo chimayatsidwa mwachangu, ndipo phindu lachuma la chitsulo chamagetsi cha ng'anjo ndi lodziwika bwino. Chitsulo chamagetsi cha ng'anjo chili ndi kufunikira kwabwino kwa magetsi amphamvu kwambiri komanso ma graphite electrode amphamvu kwambiri, komanso chidwi chachikulu chogula.
Mu 2017, mtengo wa graphite electrode m'dziko muno unakwera kwambiri, ndipo kufunikira kwa maiko akunja kunakwera. Misika yonse ya m'dziko muno ndi yakunja inabwerera ku chitukuko. Ku China, chifukwa cha kuchotsedwa kwa "chitsulo chapansi", kuwonjezeka kwa mphamvu ya ng'anjo yamagetsi, malire opanga zinthu zoteteza chilengedwe m'mabizinesi a carbon ndi zina, mtengo wa graphite electrode m'dziko muno unakwera kwambiri mu 2017, zomwe zikusonyeza kuti msika wa graphite electrode m'dziko muno ukusowa. Nthawi yomweyo, kukula kwa graphite electrode ku China kukuwonetsa kuti kufunikira kwa graphite electrode m'mayiko akunja kuli kwakukulu. M'dziko muno ndi kunja kwa dziko lapansi awonetsa kufunikira kwakukulu kwa graphite electrodes, makampani akadali ndi vuto losowa.
Chifukwa chake, kukopa ndalama kwa makampani opanga ma electrode amphamvu kwambiri a graphite kudakali kolimba.
Ndi chitukuko cha mafakitale achitsulo ndi zitsulo padziko lonse lapansi, ng'anjo yamagetsi ya arc pang'onopang'ono kupita ku mphamvu yayikulu kwambiri komanso yolamulira yokha ya makompyuta ndi zinthu zina zachitukuko, kugwiritsa ntchito ng'anjo yamagetsi ya arc yamphamvu kwambiri kukuwonjezeka, zomwe zimalimbikitsa kugwiritsa ntchito ma electrode amphamvu kwambiri a graphite.
Poyerekeza ndi United States, Europe, Japan ndi mayiko ena otukuka ndi madera ena, makampani opanga ma electrode a graphite amphamvu kwambiri ku China anayamba mochedwa, makamaka kudalira zinthu zotumizidwa kunja mwachangu, kupanga ma electrode a graphite amphamvu kwambiri sikuli kofunikira kwenikweni. Chifukwa cha chitukuko cha mafakitale achitsulo ndi zitsulo komanso kupita patsogolo kwaukadaulo, China pang'onopang'ono yaswa ulamuliro waukadaulo wa mayiko akunja, ndipo mphamvu yopanga ma electrode a graphite amphamvu kwambiri yakhala ikukwera, ndipo mtundu wa malonda nawonso wakula mofulumira. Pakadali pano, ma electrode a graphite amphamvu kwambiri omwe amapangidwa ku China apeza zotsatira zabwino mu uvuni waukulu wamagetsi, ndipo ma index onse a magwiridwe antchito a malondawa amatha kufika pamlingo wotsogola padziko lonse lapansi. Zinthu za graphite electrode zamagetsi ku China sizimangopereka msika wamkati, komanso kuchuluka kwa zinthu zotumizidwa kunja kumayiko akunja, kufunikira kwa zinthu zotumizidwa kunja kuli kochepa.
Kukula kwa kupanga zitsulo za ng'anjo kukhala zamphamvu kwambiri ndi njira yofunika kwambiri pakukula kwa makampani opanga zitsulo za ng'anjo yamagetsi. M'tsogolomu, kutulutsa kwa zitsulo za ng'anjo yamagetsi yamphamvu kwambiri kudzawonjezeka, ndipo kufunikira kwake kwa ma electrode a graphite yamphamvu kwambiri kudzawonjezekanso, zomwe zimalimbikitsa kupanga ma electrode a graphite yamphamvu kwambiri ku China. Makampani apakhomo a graphite electrode yamphamvu kwambiri amatha kuwonjezera unyolo wa mafakitale, kuchita kafukufuku ndi chitukuko cha zipangizo zopangira, ndikumanga zida zopangira, zomwe zingachepetse ndalama zamabizinesi ndikuwonjezera phindu logwira ntchito zamabizinesi.
