Lub ntsiab thermal khoom ntawm lubindustrial melting rauvsuav nrog calcination thiab sintering rauv, electrolytic tank thiabsmelting cub.Lub hauv ob sab phlu ntawm qhov chaw tua hluav taws ntawm lub qhov cub hluav taws xob feem ntau yog ua los ntawm high-alumina cib, thiab av nplaum cib tuaj yeem siv los ua cov hauv ob sab phlu rau lwm qhov chaw.Ib txheej ntawm refractory fiber ntau yog nteg rau ntawm tshav kub rwb thaiv tsev txheej nyob ze ntawm lub cub tawg, thiab ces ib txheej ntawm lub teeb ci ci los yog lub teeb ci ci.Zoo refractory castable pouring.
Lub plhaub ntawm electrolytic cell yog ua los ntawm steel phaj, thiab ib txheej ntawm rwb thaiv tsev board los yog refractory fiber xav tau pw nyob rau hauv lub plhaub, ces lub teeb ci ci los yog lub teeb refractory castables yog poured, thiab ces av nplaum cib yog tsim rau tsim cov txheej txheem tsis ua haujlwm, thiab cov khoom siv hluav taws xob ua haujlwm Cov txheej txheem tsuas yog ua los ntawm cov pa roj carbon lossis silicon carbide refractory cov ntaub ntawv nrog cov khoom siv hluav taws xob zoo, thiaj li tiv thaiv kev nkag mus ntawm molten aluminium thiab yaig ntawm fluoride electrolyte.Yav dhau los, cov txheej txheem ua haujlwm ntawm cov phab ntsa ntawm cov xov tooj ntawm tes electrolytic feem ntau yog ua nrog cov pa roj carbon blocks.Nyob rau hauv xyoo tas los no, Nyiv thiab qee lub tebchaws nyob sab Europe sab hnub poob tau siv silicon carbide cib ua ke nrog silicon nitride los tsim lawv, thiab ua tiav cov txiaj ntsig zoo.
Cov txheej txheem ua haujlwm nyob rau hauv qab ntawm electrolytic cell feem ntau yog ua los ntawm cov pa roj carbon blocks nrog cov pob qij txha me thiab ntim nrog cov pa roj carbon monoxide los tiv thaiv kev nkag mus ntawm cov tshuaj txhuas thiab txhim khu kev ua haujlwm.
Feem ntau siv aluminiumkhoom siv smeltingyog lub reverberatory rauv.Lub tshuab hluav taws xob hauv ob sab hauv kev sib cuag nrog cov tshuaj txhuas feem ntau yog ua los ntawm high-alumina cib nrog cov ntsiab lus A1203 ntawm 80% -85%.Thaum smelting high-purity hlau txhuas, mullite cib los yog corundum cib yuav tsum tau siv.Hauv qee lub tsev lag luam, silicon carbide cib ua ke nrog silicon nitride yog siv los ua cov masonry ntawm qhov chaw uas muaj kev yaig thiab hnav, xws li txoj kab nqes ntawm lub hearth thiab cov ntaub ntawv pov tseg aluminium.Nws tus kheej-bonded los yog silicon nitride-bonded silicon carbide cib kuj siv los ua ob sab nrog zircon cib.Rau qhov blockage ntawm aluminium qhov hluav taws xob, cov nyhuv ntawm lub tshuab nqus tsev casting refractory fiber yog zoo dua.Rauv hauv ob sab phlu uas tsis hu rau cov tshuaj txhuas yog feem ntau ua nrog av nplaum cib, av nplaum refractory castables los yog refractory plastics.Txhawm rau kom ceev cov melting ceev thiab txuag lub zog, lub teeb ci ci, lub teeb yuag refractory castables thiab refractory fiber ntau yog feem ntau siv los ua cov txheej txheem cua sov.
Aluminium smelting induction crucible rauv kuj tseem siv cov khoom siv.Lub hauv ob sab phlu feem ntau yog ua los ntawm high-alumina refractory castable los yog refractory ramming khoom nrog A1203 cov ntsiab lus ntawm 70% -80%, thiab corundum refractory qhob kuj siv los ua hauv ob sab phlu.
Lub molten aluminium ntws tawm los ntawm txhuas qhov hluav taws xob ntawm lub cub tawg los ntawm cov txhuas ntws tank.Lub tank hauv ob sab phlu feem ntau yog ua los ntawm silicon carbide cib, thiab tseem muaj cov blocks prefabricated ntawm fused silica xuab zeb.Yog hais tias lub prefabricated thaiv yog siv los ua ib lub tank hauv ob sab phlu, qhov saum npoo yuav tsum tau coated nrog fused silica xuab zeb los yog Siv siab alumina cement fused silica xuab zeb refractory castable li tiv thaiv txheej.
