instant silicon

Instant silicon Hlau silicon, tseem hu ua industrial silicon, yog ib qho khoom siv dav siv hauv cov hlau smelting thiab siv los ua tus neeg sawv cev hauv cov txheej txheem smelting.Silicon kuj yog ib qho zoo tivthaiv hauv txhuas alloys, thiab feem ntau cam khwb cia txhuas alloys muaj silicon.Lub instant silicon yog sab nrauv ntawm silicon hlau ntxiv rau flux.Kev ua haujlwm ntawm cov flux yog tsim kom muaj cua sov ntau hauv cov txheej txheem ntawm cov hlau smelting, kom cov hlau silicon melts sai, thiab cov tshuaj tiv thaiv kub ntawm cov flux feem ntau tsis siab, txog 740 degrees Celsius, yog li no hom hlau silicon. nrog flux ntxiv tseem hu ua instant silicon.Siv los kho cov ntsiab lus ntawm silicon hauv aluminium alloys.

Qhov zoo ntawm kev siv instant silicon

1. Lub dissolution ceev yog ceev heev, cov tshuaj tiv thaiv yog ceev, thiab lub sij hawm tau txais kev cawmdim.

2. Cov ntsiab lus yog siab li 95%, uas muaj peev xwm tswj tau cov nyiaj ntawm silicon ntxiv, thiab ceev nrooj configure ib feem ntawm aluminium-silicon alloy.

3. Nws yog qhov yooj yim heev rau kev siv, tsuas yog muab tso rau saum npoo ntawm cov kua txhuas, nias rau hauv thiab do.Tus nqi rov qab yog ntau dua 90%.

4. Ib qho zoo tagnrho hloov khoom rau txhuas-silicon intermediate alloys.Nws tshem tawm ntau qhov kev suav nrog thiab cov khoom tsis zoo uas tau yooj yim coj mus rau hauv aluminium-silicon alloys, thiab zam kev siv cov khib nyiab thiab lwm yam txhuas los npaj aluminium-silicon alloys, uas yog qhov nyuaj rau kev tswj xyuas qhov zoo ntawm qhov kawg aluminium alloy.

5. Txo qhov kub thiab txias, txo lub sij hawm melting, thiab txo cov nqi ntawm cov khoom xyaw alloy.

Daim ntawv thov

Txhua yam silicon-muaj cam khwb cia lossis wrought aluminium uas muaj kub.Siv qhov kub thiab txias: 740-770 ℃ (qhov kub siab dua, cov nyhuv zoo dua)

Yuav siv li cas

Tom qab tag nrho cov nqi yog melted, do zoo thiab coj mus kuaj rau kev soj ntsuam.Xam qhov sib ntxiv ntawm cov silicon ceev ceev raws li cov txiaj ntsig kev soj ntsuam.Thaum cov txhuas molten nce mus txog 740-770 ° C (tus txheej txheem ntawm kev ntxiv silicon yog cov tshuaj tiv thaiv endothermic, qhov kub ntawm cov hlau molten yuav tsum tau rhuab kom qhov kub thiab txias tsis qis dua 740 ° C), pov cov silicon tus neeg sawv cev tam sim ntawm lub molten. aluminium nto rau kev siv, thiab nias lub tswb rau hauv molten aluminium.Do hauv 2-5 feeb.Cov lus piav qhia: Cov ntsiab lus silicon yog 95%, thiab nws tuaj yeem yaj sai sai ntawm qhov kub thiab txias, uas txo cov nqi ntawm cov khoom xyaw alloy, thiab tuaj yeem npaj cov khoom siv silicon-aluminium sai sai nrog cov ntsiab lus silicon;Cov kev tswj muaj pes tsawg leeg yog qhov tseeb heev, thiab ntau qhov kev suav nrog thiab cov khoom tsis zoo uas tau yooj yim coj mus rau hauv tus tswv alloy raug tshem tawm.Impurities, kom tsis txhob siv cov khib nyiab lwm yam txhuas los npaj aluminium-silicon master alloys thiab cuam tshuam rau qhov zoo ntawm qhov kawg aluminium alloy uas nyuaj rau kev tswj.
