Dab tsi yog cov khoom siv refractory siv hauv txhuas qhov cub cua sov?

Cov khoom siv refractory rau txhuas qhov cub muaj cua sov feem ntau yog cov cib ua hluav taws kub hnyiab thiab cov khoom pov tseg, tab sis kev xaiv nws txawv heev raws li qhov sib txawv. Refractories rau txhuas qhov cub tsim hluav taws xob yuav tsum muaj lub siab ua kom lub zog loj, qhov taub me me, cov ntsiab lus qis ntawm SiO2, Na2O, thiab K2O. Lub qhov cub cua sov yuav tsum muaj kev ua haujlwm zoo ntawm qhov kub ntawm 800 ° C. Tus kws kho mob ntawm Kerui Refractories tau suav sau cov khoom siv hluav taws xob ntau rau txhuas qhov cub cua sov rau koj siv xwb.

Cov txheej rwb thaiv tsev cua sov ntawm lub alumina rotary kiln tau npog los ntawm txheej txheej ntawm cov khoom siv hluav taws xob uas muaj nyob rau ntawm lub plhaub kiln, thiab tom qab ntawd ua nrog lub ntiaj teb diatomaceous, ntab cov hlaws cib lossis cov av nplaum av nplaum, thiab qee qhov tam sim no tau hloov nrog lub teeb ci ntsa iab. Cov txheej txheem ua haujlwm ntawm thaj tsam ua ntej cua sov yog ua nrog cov av nplaum cib, thiab cov av alumina siab lossis phosphate-bonded high-alumina cib tau siv rau thaj tsam kub kub.

Tam sim no, cov khoom siv refractories uas tsis tau hloov pauv tau siv dav hauv kev lag luam txhuas, xws li cov tshuaj calcium-aluminate-qis refractory castable hauv thaj tsam calcination, thiab cov hlau fiber ntau ntxiv rau hnav-resistant castables rau lub qhov ncauj qhov ncauj, lub qhov ncauj qhov ntswg, thiab cov tis kiln.

Lub tshuab ua hluav taws xob ntsaws yog txhawm rau txhim kho cov cua sov uas tiv taus cov ntsia hlau ntsia hlau lossis cov thauj tog rau nkoj ntawm lub plhaub rauv, tom qab ntawd nthuav tawm txheej txheej ntawm 20mm tuab cov khoom siv hluav taws xob ua kom muaj zog, thiab thaum kawg ncuav 200-300 tuab cov nplaim hluav taws.

Cov txheej txheem ua haujlwm ntawm lub tshuab ua kom rov ua dua tshiab ntawm aluminium smelting rauv nyob rau hauv kev sib cuag nrog cov txhuas yaj yog feem ntau ua nrog cov qib alumina siab nrog Al2O3 cov ntsiab lus ntawm 80-85%; thaum smelting high-purity hlau txhuas, mullite cib lossis corundum cib tau siv. Ntawm qhov nqes hav ntawm qhov hearth, teeb tsa cov khib nyiab txhuas thiab lwm yam yooj yim corroded thiab hnav qhov chaw, thiab siv cov tshuaj silicon nitride los ua ke nrog cov pob zeb silicon nitride. Ntws aluminium troughs thiab aluminium qhov hluav taws xob raug scoured los ntawm aluminium molten. Feem ntau, nws tus kheej sib txuas lossis silicon nitride sib txuas silicon carbide cib tau siv, thiab cov zircon cib kuj tseem siv ua cov ntaub. Lub qhov cub cua sov uas tsis tiv tauj rau txhuas txhuas feem ntau siv cov av nplaum, cov av nplaum uas tsis tuaj yeem ua tau lossis cov yas uas tsis tuaj yeem ua tau.

Cov khoom siv hluav taws xob ua hluav taws xob ua kom tawg rau txhuas thiab txhuas alloys feem ntau yog cov khoom siv aluminium qhuav ramming, lossis silicon carbide tau ntxiv rau cov khoom siv alumina qhuav ramming, uas tsis nquag ua rau cov dej xau.
