Cov tshwm sim txawv txav thiab kev kho mob ntawm corundum dawb ua ntej smelting rauv

1. Cov arc tawg
Nta: Tsis muaj cov zaub tam sim no, tsis muaj suab nrov hauv qhov cub, tsis muaj flash ntawm electrodes.
Ua rau: lub pas nrig arc tsis kho kom zoo, lub pas nrig tshem tawm tau ua ntxov dhau, thiab cov kua molten tsawg dua; Thaum cov khoom noj ceev dhau lawm, cov txhuas cov pa oxygen yog raus los thaiv txoj hauv kev tam sim no, lub tshuab hluav taws xob cov tshuaj tiv thaiv ua ib qho nyuaj, thiab cov electrode raug thaiv los ntawm kev poob.
Kev daws: xyuas ua ntej pib arc; Tom qab qhov cua sov qhov xwm txheej yog qhov ruaj khov dua, cov pas nrig carbon tau muab rho tawm. Ua tib zoo saib xyuas qhov ceev ceev pub mis; Txav cov electrode nquag thaum lub tshuab hluav taws xob series; Rov qab.
Thib ob, hlua hluav taws xob
Nta: Cov kua molten ntws sai sai rov qab los rau hauv cov hmoov nplej, nplawm ntau cov hmoov txhuas oxide, qee zaum ua rau arc tawg, feem ntau tshwm sim li ntawm 10h tom qab lub qhov cub qhib.
Ua rau: sab ntawm cov khoom txheej yog tuab, lub qhov cub hauv qab melting nto yog me me, kev pub mis tsis sib npaug, ua rau cov cua sov tsis sib xws, ib feem ntawm cov kua nplaum thiab cov phab ntsa ntawm lub cub tawg los yog lub cub tawg siab yog loj, cov kua molten thiab ntau cov khoom txias rau hauv.
Kev daws: nyob rau hauv thawj ob peb teev, qis voltage yog siv los nthuav cov melting nto thiab ua kom cov kua ntim; Yog tias loj heev, rhuav tshem qhov nyuaj, theem tus nqi, thiab ua tib zoo nrog nws.
Peb, tua
Nta: Sudden roar nyob rau hauv lub cub tawg, ejected ntau cov roj kub, hluav taws kub, tsis muaj qhov cub hauv ob sab phlu, lub cub tawg lub plhaub ntawm qhov chaw blasting liab, hnyav ua rau lub qhov cub tawg.
Ua rau: lub cub tawg hauv qab, qhov cub hauv ob sab phlu ntub dej, cov ntaub ntawv ntub dej, cov khoom siv sab nrauv yog tuab heev, kev ua haujlwm tsis zoo, ua rau lub qhov cub tawg ntau dhau.
Kev daws: tiv thaiv hauv qab ntawm lub cub tawg ntub; Tswj raw cov ntaub ntawv noo noo; Txhim kho kev ua haujlwm kom ntseeg tau tias cov khoom siv sib xws; Ua kom cov dej txias kom ntau yam tsis muaj lub qhov cub; Kev kho mob raws sij hawm, rhuav tshem cov coagulate, theem tus nqi;
Plaub, "txhim kho qhov cub hauv ob sab phlu"
Nta: molten kua thiab furnace hauv ob sab phlu cov tshuaj tiv thaiv, molten kua billow dhia hla cov khoom txheej, loj, them nyiaj yog nyuaj rau nias, thiab txawm lub cub tawg tawg.
Ua rau: kev ua haujlwm tsis raug, kev noj zaub mov tsis sib xws lossis tsis xis nyob, cov khoom txheej sab nraud ntawm cov electrode nyias nyias, cov electrode nyob ze rau ntawm phab ntsa ntawm lub qhov cub, qhov hluav taws xob tsawg dhau.
Kev daws: Ntxiv cov khoom pov tseg dawb corundum rau sab nraud ntawm cov electrode, particle loj 20-40mm; Kho qhov voltage lossis electrode nrug; Txo qhov tam sim no, txo lub zog tawm tswv yim, nce cov dej txias; Yog tias tsim nyog, nres qhov cub kho.
