Chiyambi cha electrode ya Graphite

Electrode ya graphiteimagwiritsidwa ntchito kwambiri popanga zitsulo za EAF. Kupanga zitsulo za ng'anjo yamagetsi kumagwiritsa ntchito graphite electrode kuti ilowetse mphamvu mu ng'anjo. Mphamvu yamphamvu imapanga kutulutsa kwa arc kudzera mu mpweya kumapeto kwa electrode, ndipo kutentha komwe kumapangidwa ndi arc kumagwiritsidwa ntchito posungunula. Malinga ndi mphamvu ya ng'anjo yamagetsi, ma graphite electrode okhala ndi mainchesi osiyanasiyana amagwiritsidwa ntchito. Kuti ma electrode agwiritsidwe ntchito mosalekeza, ma electrode amalumikizidwa ndi cholumikizira cha electrode.maelekitirodi a graphiteKupanga zitsulo kumapanga 70-80% ya kuchuluka kwa ma electrode a graphite. 2、 Amagwiritsidwa ntchito mu ng'anjo yamagetsi yotentha ya mgodi. Khalidwe lake ndilakuti gawo lotsika la ma electrode oyendetsera magetsi limakwiriridwa mu charge. Chifukwa chake, kuwonjezera pa kutentha komwe kumapangidwa ndi arc pakati pa mbale yamagetsi ndi charge, kutentha kumapangidwanso ndi kukana kwa charge pamene mphamvu ikudutsa mu charge. 3、 Furnace ya Graphitization, ng'anjo yosungunuka ndi galasi ndi ng'anjo yamagetsi yopangira zinthu za graphite zonse ndi ng'anjo zotsutsa. Zipangizo zomwe zili mu ng'anjo sizimangoteteza kutentha kokha, komanso zimatenthetsa. Nthawi zambiri, ma electrode oyendetsera magetsi amayikidwa mu khoma la mutu wa ng'anjo kumapeto kwa moto, kotero ma electrode oyendetsera magetsi sagwiritsidwa ntchito nthawi zonse.

Magawo ogwiritsira ntchito:

(1) Imagwiritsidwa ntchito mu uvuni wamagetsi wopanga zitsulo, womwe ndi wogwiritsa ntchito kwambirimaelekitirodi a graphiteKu China, kutulutsa kwa chitsulo cha EAF kumaphatikizapo pafupifupi 18% ya kutulutsa kwa chitsulo chosaphikidwa, ndipo electrode ya graphite yopangira zitsulo imafikira 70% mpaka 80% ya kuchuluka kwa ma electrode a graphite omwe amagwiritsidwa ntchito. Kupanga chitsulo cha ng'anjo yamagetsi ndi kugwiritsa ntchito electrode ya graphite kuti ilowetse mphamvu mu ng'anjo, ndikugwiritsa ntchito gwero la kutentha kwambiri lopangidwa ndi arc pakati pa mapeto a electrode ndi mphamvu kuti isungunuke.

2) Imagwiritsidwa ntchito mu ng'anjo ya arc yonyowa; ng'anjo ya arc yonyowa imagwiritsidwa ntchito makamaka popanga silicon yamakampani ndi phosphorous yachikasu, ndi zina zotero. Izi zimadziwika kuti gawo la pansi la electrode yoyendetsa limakwiriridwa mu charge, ndikupanga arc mu charge layer, ndikutenthetsa charge pogwiritsa ntchito mphamvu yotentha yopangidwa ndi kukana kwa charge yokha. Ng'anjo ya arc yonyowa yokhala ndi mphamvu yayikulu yamagetsi imafuna graphite electrode, mwachitsanzo, graphite electrode ya pafupifupi 100kg imafunika pa 1t iliyonse yopanga silicon, ndipo graphite electrode ya pafupifupi 100kg imafunika pa 1t iliyonse yopanga silicon. Pafupifupi 40 kg ya graphite electrode imafunika pa phosphorous yachikasu ya t.

(3) Imagwiritsidwa ntchito pa ng'anjo yolimbana ndi kupondereza; ng'anjo ya graphitization yopanga zinthu za graphite, ng'anjo yosungunula galasi ndi ng'anjo yamagetsi yopanga silicon carbide zonse ndi za ng'anjo yolimbana ndi kupondereza. Zipangizo zomwe zili mu ng'anjo ndi zotsutsana ndi kutentha komanso zotenthetsera. Nthawi zambiri, electrode ya graphite yoyendetsa imayikidwa mu khoma la mutu wa ng'anjo kumapeto kwa ng'anjo yolimbana ndi kupondereza, ndipo electrode ya graphite yomwe imagwiritsidwa ntchito pano sigwiritsidwa ntchito nthawi zonse.

(4) Amagwiritsidwa ntchito pokonzekera mawonekedwe apaderazinthu za graphite; chopanda kanthu cha graphite electrode chimagwiritsidwanso ntchito pokonza zinthu zosiyanasiyana zapadera za graphite monga chophikira, nkhungu, mbale ya boti ndi thupi lotenthetsera. Mwachitsanzo, mumakampani opanga magalasi a quartz, chopanda kanthu cha graphite electrode cha 10t chimafunika pa chubu chilichonse chamagetsi chosungunula cha 1t; chopanda kanthu cha graphite electrode cha 100kg chikufunika pa njerwa iliyonse ya quartz ya 1t.
