ferrosilicon 75
Feem ntau ntawm cov pa roj carbon monoxide muaj nyob rau hauv daim ntawv ntawm cov pa roj carbon monoxide, tab sis cov pa roj carbon tsawg kuj muaj nyob rau hauv daim ntawv ntawm hydrocarbons (feem ntau hu ua volatiles). Qhov no ntawm cov hydrocarbons volatilizes deb ntawm qhov kub thiab txias, yog li cov ntsiab lus volatile ntawm coke yuav tsum tsis txhob ntau tshaj 2%.

Ntxiv nrog rau cov tshuaj muaj pes tsawg leeg ntawm coke, kuj tseem muaj cov kev xav tau rau nws lub cev lub cev. Qhov ntau dua qhov kev tiv thaiv ntawm coke ntawm qhov kub thiab txias, qhov tob ntawm cov electrode yog ntxig rau hauv tus nqi, uas yuav pab ua kom lub cub tawg kub thiab yog li ua kom lub crucible loj. Qhov loj porosity ntawm coke tsis tsuas yog muaj kev ua haujlwm siab, tab sis kuj muaj thaj chaw loj, uas ua rau thaj chaw tshuaj lom neeg thiab ua kom nrawm nrawm ntawm cov tshuaj tiv thaiv.

Qhov loj me me ntawm coke muaj qhov cuam tshuam zoo rau smelting. Thaum cov particle loj dhau lawm, qhov kev tiv thaiv ntawm tus nqi txo, thiab nws yog ib qho nyuaj rau cov electrode yuav tsum tau ntxig rau hauv tus nqi, uas ua rau lub cub tawg qis, me me crucible, thiab smelting txawv txav. Yog hais tias qhov loj me me dhau los yog muaj cov hmoov ntau dhau, qhov kev hlawv yuav ntau dua, uas yuav yooj yim ua rau lub cub tawg nplaum thiab cuam tshuam rau huab cua permeability ntawm cov khoom nto. Yog li ntawd, coke yuav tsum muaj qee qhov me me. Qhov loj me ntawm coke siv nyob rau hauv loj ferrosilicon hluav taws xob rauv yog nyiam dua tsawg dua 8 hli. Qhov kub ntawm qhov me me ferrosilicon hluav taws xob rauv yog qhov tsawg. Txhawm rau kom qhov kub thiab txias, cov txheej txheem "smoldering" yog siv rau hauv kev ua haujlwm. Ntxiv qee cov hmoov coke tuaj yeem pab cov sintering ntawm cov khoom nto, kom cov electrode tuaj yeem nkag mus tob rau hauv cov khoom siv hluav taws xob. Yog li ntawd, thaum smelting nyob rau hauv ib tug me me-muaj peev xwm ferrosilicon hluav taws xob rauv, me me ntawm coke hmoov yuav siv tau.
Tsis muaj cov cai tshwj xeeb rau lub cev lub cev ntawm coke. Lub coke tsim nyog yuav raug xaiv raws li kev xyaum ua ntau lawm.
Tam sim no, cov coke siv rau smelting ferrosilicon nyob rau hauv kuv lub teb chaws yog feem ntau me me-grained coke uas tau raug soj ntsuam los ntawm cov coke siv nyob rau hauv blast furnace smelting.
