Tsawg creep siab alumina cib

Tsawg creep siab alumina cib yog hom cib alumina siab uas tiv taus kub ntau dua li lwm cov khoom lag luam zoo sib xws, tuaj yeem txuag kev siv coke thiab nce cov hlau tawm. Qhov refractoriness ntawm qib siab alumina cib yog siab dua li ntawm cov av nplaum cib thiab cov pob zeb ib nrab silica, mus txog 1750 ~ 1790 ℃, uas yog rau cov khoom siv hluav taws xob siab. Tsawg creep thiab siab alumina cib yog ua raws “peb-pob zeb” txoj kev xav. Xaiv bauxite thiab av nplaum ua cov khoom siv tseem ceeb, ntxiv cov kyanite uas tsim nyog, andalusite thiab sillimanite, feem ntau hu ua “peb lub pob zeb”, tswj lub cev thiab tshuaj ntsuas thiab cov khoom muaj pes tsawg leeg, siv bauxite + mullite + corundum thiab lwm yam ntaub ntawv raw li cov phiaj xwm thev naus laus zis . Hauv cov txheej txheem tsim khoom, cov ntaub ntawv raw khoom tau pom thawj zaug thiab tswj hwm. Tom qab tsoo, tsoo, thiab tshuaj ntsuam, cov khoom xyaw tau muab faib raws qhov sib piv. Tom qab sib tov thiab sib tsoo, qhov loj me me thiab cov dej noo ntawm cov av nkos tau tswj kom ua tau raws li qhov yuav tsum tau ua molding. Kev tsim nyog abrasives tuaj yeem tswj tus naj npawb ntawm tshuab, qhov ntev thiab flashing ntawm molding, thaum kuaj cov khoom ib nrab ua tiav thiab kev ua tau zoo kom tau raws li qhov xav tau tshwj xeeb. Cov txheej txheem tsim tawm: siv qhov kub thiab txias calcined super bauxite, ntxiv cov khoom kub-kub nrog qhov nkag qis, thiab ua rau lub siab ua kom siab thiab ua kom sov kub. Nws muaj cov yam ntxwv ntawm lub zog siab, qis tus nqi nkag thiab qhov kub ua haujlwm siab. Nws tau siv dav hauv cov cua sov hauv ob sab phlu thiab ntsuas cov cib ntawm cov cua kub kub thiab cov cua kub tawg.

Khoom nta:

1. Tsawg tus tsiaj nkag thiab kub me me nkag.

2. Lub load softening kub yog siab.

3. Ua tau zoo tiv taus.

4. Kub thiab siab zog.

5. Zoo ntim ruaj ntseg ntawm qhov kub thiab zoo hnav tsis kam.

6. corrosion kuj zoo.

Vim tias cov khoom siv alumina refractory cib muaj siab Al2O3 siab dua, tsis muaj qhov tsis zoo thiab tsis muaj iav ntau dua, qhov hnyav ua kom sov siab dua li ntawm cov av nplaum cib, tab sis vim tias mullite muaju tsis tsim cov qauv network, lub ntsuas kub ua kom sov tseem tsis yog cov cib cib siab.

Tsawg creep thiab siab alumina cib muaj ntau dua Al2O3, uas yog ze rau cov khoom siv hluav taws xob nruab nrab, thiab tuaj yeem tiv taus qhov yaig ntawm cov kua qaub slag thiab alkaline slag. Txij li thaum lawv muaj SiO2, lub peev xwm los tiv thaiv alkaline slag tsis muaj zog dua li cov kua qaub slag.

Khoom Pab:

Qes qis-qib siab alumina cib yog ua los ntawm qib tshwj xeeb bauxite clinker ua cov khoom siv tseem ceeb, ntxiv los ntawm cov tshuaj tshwj xeeb ntxiv. Tom qab ua kom muaj kev kub siab thiab kub kub, lawv muaj qhov zoo ntawm qhov muaj peev xwm cia cua sov loj thiab tus nqi nkag qis. Lawv tsim nyog rau qhov cub tawg me me thiab nruab nrab. Cov cua kub qhov cub.

Tsawg creep thiab qib siab alumina cib rau qhov cub tawg thiab qhov cub tawg tawg tau siv rau tawg rauv taws kub kais raws. Cov txheej txheem pov tseg tau txais AI2O3-SiC-C series. Nws muaj cov yam ntxwv zoo ntawm kev tiv thaiv corrosion, yaig tsis kam thiab siab thermal stability. Nws tuaj yeem siv rau lub ntsiab lus tseem ceeb ntawm lub qhov cub tawg. Cov kab hlau kub, kab slag, viav vias taub hau, lub tank hlau seem, sab saum toj ntawm lub hauv paus tseem ceeb npog, ob sab ntawm lub hauv paus loj npog, hlau ditch, slag ditch, thiab lwm yam.
