Qhov zoo ntawm Graphite Electrodes hauv Steelmaking
Graphite electrodes yog ib qho tseem ceeb ntawm kev lag luam steelmaking vim lawv ua lub luag haujlwm tseem ceeb hauv Electric Arc Furnace (EAF) steelmaking txheej txheem. Ua los ntawm graphite, ib tug crystalline daim ntawv ntawm carbon, cov high-kev ua tau zoo electrodes yog siv raws li ib tug conductive cov ntaub ntawv los hloov hluav taws xob zog rau lub hluav taws xob arc rauv. Graphite electrodes ua tau zoo dua lwm cov ntaub ntawv vim lawv cov thermal conductivity, tsis tshua muaj thermal expansion, thiab zoo heev hluav taws xob conductivity.

Lub Tshuab Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob (EAF) cov txheej txheem steelmaking yuav cuam tshuam cov hlau nplaum thiab lwm yam khoom siv raw hauv lub cub tawg siv graphite electrodes. Cov electrodes tau muab tso rau hauv qhov cub thiab ib qho hluav taws xob tam sim no dhau los ntawm lawv los tsim ib qho arc, uas tsim cov cua sov uas melts cov ntaub ntawv raw. Tom qab ntawd cov hlau molten yog muab pov rau hauv cov duab uas xav tau.

Graphite electrodes feem ntau yog siv hauv kev lag luam steelmaking, tab sis lawv tuaj yeem siv los tsim lwm yam hlau xws li txhuas thiab tooj liab. Cov electrodes muaj nyob rau hauv ntau txoj kab uas hla, qhov ntev, thiab qib kom haum rau qhov sib txawv ntawm qhov cub thiab qhov yuav tsum tau ua.

Cov txheej txheem tsim khoom ntawm graphite electrodes suav nrog kev siv cov roj av zoo coke thiab rab koob coke ua cov khoom siv raw. Cov ntaub ntawv raw yog crushed, tov nrog thee tar suab thiab ci nyob rau hauv lub cub tawg ntawm kub tshaj 2, 000 degree los tsim cov khoom graphite blocks. Cov blocks raug txiav mus rau hauv cov duab thiab qhov loj me los tsim cov khoom kawg.
