Silicon hlau 411

Cov hlau siliconsmelting belongs rau lub zog noj ntau lawm, cov hlau silicon ntau lawm nyob rau hauv peb lub teb chaws tau ntev lawm, nrog rau lub teb chaws zog txoj cai nruj thiab kev loj hlob ntawm lub zog txuag thiab emission txo, raws li zoo raws li kev txhawb zog tshiab, hlau silicon. smelting tau dhau los ua cov khoom lag luam thiab cov txheej txheem. Ntau lub tuam txhab tsim hluav taws xob hauv tsev tau tsim cov kev lag luam sib txuas, xws li hlau silicon, polysilicon, monocrystalline silicon, hnub ci hlwb, thiab lwm yam, ob peb xyoos tom ntej no yuav cuam tshuam rau kev txhim kho ntawm Tuam Tshoj lub zog tag nrho thiab kev siv lub zog tshiab. .

Hlau silicon yog tsim los siv txoj kev carbothermal, uas yog ib txoj kev ntawm smelting silica thiab carbonaceous txo cov neeg ua hauj nyob rau hauv lub submerged arc rauv. Lub purity ntawm silicon ua nyob rau hauv no txoj kev yog 97% mus rau 98%, thiab xws li silicon feem ntau yuav siv tau rau metallurgical lub hom phiaj. Yog tias koj xav kom tau txais qib siab dua silicon, koj yuav tsum tau ua kom zoo dua kom tshem tawm cov impurities kom tau cov hlau silicon nrog cov purity ntawm 99.7% mus rau 99.8%.

Tam sim no, cov txheej txheem ntau lawm ntawm carbothermal txoj kev tsim cov hlau silicon hauv Suav teb yog: silica feem ntau yog siv los ua raw khoom, roj av coke, charcoal, ntoo chips, low-ash thee, thiab lwm yam. smelted ntawm kub kub nyob rau hauv lub submersible hluav taws xob rauv kom tau silica los ntawm silica. Hlau silicon rov qab, uas yog ib qho slag-dawb submerged arc high-temperature smelting txheej txheem.
