Graphite electrodeFeem ntau yog siv hauv EAF steelmaking. Hluav taws xob rauv steelmaking yog siv graphite electrode los qhia tam sim no rau hauv qhov cub. Qhov muaj zog tam sim no ua rau arc tawm los ntawm cov pa roj ntawm qhov kawg ntawm cov electrode, thiab cov cua sov tsim los ntawm arc yog siv rau smelting. Raws li lub peev xwm ntawm lub cub hluav taws xob, graphite electrodes nrog txawv diameters yog siv. Txhawm rau ua kom cov electrodes tsis tu ncua, cov electrodes txuas nrog cov electrode threaded sib koom ua ke. Covgraphite electroderau steelmaking nyiaj rau 70-80% ntawm tag nrho cov nyiaj ntawm graphite electrode. 2, Nws yog siv nyob rau hauv mine thermal fais fab cub. Nws cov yam ntxwv yog tias qhov qis ntawm cov hluav taws xob electrode yog faus rau hauv tus nqi. Yog li ntawd, nyob rau hauv tas li ntawd mus rau lub tshav kub generated los ntawm lub arc ntawm lub phaj hluav taws xob thiab tus nqi, lub tshav kub kuj yog generated los ntawm cov kuj ntawm tus nqi thaum lub tam sim no dhau los ntawm tus nqi. 3 、 Graphitization rauv, iav melting rauv thiab hluav taws xob rau cov khoom siv graphite yog tag nrho cov cua sov ua haujlwm. Cov ntaub ntawv nyob rau hauv lub qhov cub tsis yog tsuas yog cua sov, tab sis kuj cua sov khoom. Feem ntau, cov conductive graphite electrode yog muab tso rau hauv lub cub tawg lub taub hau phab ntsa ntawm qhov kawg ntawm lub hearth, yog li cov conductive electrode tsis noj tas li.
Daim ntawv thov teb:
(1) Nws yog siv rau hauv hluav taws xob arc steelmaking rauv, uas yog cov neeg siv loj ntawmgraphite electrode. Nyob rau hauv Tuam Tshoj, cov zis ntawm EAF steel account rau txog 18% ntawm cov khoom siv raw khoom, thiab cov graphite electrode rau steelmaking account rau 70% ~ 80% ntawm tag nrho cov graphite electrode. Hluav taws xob rauv steelmaking yog siv cov graphite electrode los qhia tam sim no rau hauv lub cub tawg, thiab siv cov kub kub qhov chaw uas tsim los ntawm cov arc nruab nrab ntawm qhov kawg ntawm cov electrode thiab tus nqi rau smelt.
2) Nws yog siv nyob rau hauv submerged arc rauv; submerged arc rauv yog tsuas yog siv los ua cov khoom lag luam silicon thiab daj phosphorus, thiab lwm yam, nws yog tus cwj pwm los ntawm qhov qis ntawm cov hluav taws xob hluav taws xob yog faus rau hauv tus nqi, tsim ib qho arc hauv cov txheej txheem, thiab cua sov tus nqi los ntawm kev siv lub zog hluav taws xob. generated los ntawm qhov tsis kam ntawm tus nqi nws tus kheej. Lub submerged arc rauv uas muaj ntau dua tam sim no xav tau graphite electrode, piv txwv li, txog 100kg graphite electrode yog xav tau rau txhua 1t silicon ntau lawm, thiab hais txog 100kg graphite electrode yog xav tau rau txhua txhua 1t silicon ntau lawm txog 40 kg ntawm graphite electrode yog xav tau rau t daj. phosphorus.
(3) Nws yog siv rau cov cua sov ua haujlwm; graphitization rauv rau ua cov khoom graphite, rauv rau melting iav thiab hluav taws xob rauv rau ua silicon carbide tag nrho cov nyob rau hauv lub cub tawg. Cov ntaub ntawv nyob rau hauv lub cub tawg yog ob qho tib si cua sov tsis kam thiab rhuab khoom. Feem ntau, cov conductive graphite electrode yog embedded nyob rau hauv lub cub tawg lub taub hau phab ntsa ntawm qhov kawg ntawm lub qhov cub, thiab cov graphite electrode siv ntawm no tsis tas yuav noj.
(4) Nws yog siv los npaj tshwj xeeb-zoo li tusgraphite khoom; qhov khoob ntawm graphite electrode kuj yog siv los ua ntau yam khoom tshwj xeeb zoo li graphite xws li crucible, pwm, nkoj tais thiab cua sov lub cev. Piv txwv li, hauv kev lag luam quartz iav, 10t graphite electrode yog xav tau rau txhua 1t hluav taws xob melting raj; 100kg graphite electrode yog xav tau rau txhua 1t quartz cib.
