Xaiv Cov Khoom Raw Thiab Particle Loj Rau Tsawg Creep Refractory Bricks

Kev xaiv cov khoom siv raw thiab qhov loj me rau cov khoom siv qis qis refractory cib

1. Cov khoom siv raw
Hauv cov khoom siv AL2O3-SiO2, mullite thiab corundum yog cov ntaub ntawv tseem ceeb, thiab muaj ntau yam khoom siv raw, siv mullite ua piv txwv. Yuav xaiv cov khoom siv raw li cas?
Cov txheej txheem xaiv:
1. Cov yam ntxwv ntawm txhua yam khoom siv raw;
2. Tus nqi tsim nyog. Feem ntau hais lus, txoj kev loj hlob ntawm fused mullite crystals yog zoo dua li ntawm sintered mullite crystals, thiab lub moj khaum tsim los ntawm interlocking ntawm mullite muaju yog qhov ruaj khov; Tsawg tus ciam teb txo cov qoob loo ciam teb, uas muaj txiaj ntsig zoo rau kev nkag mus. Yog li ntawd thaum ua cov creep refractory cib tsawg, * * xaiv fused mullite. Qhov zoo ntawm sintered mullite los ntawm ntau hom, nrog rau alumina raws li mullite, yog superior rau cov coj alumina raws li mullite; Piv nrog rau cov npe sib xws ntawm alumina raws li mullite, "peb lub pob zeb" zoo mullite muaj cov ntsiab lus ntau dua ntawm mullite thiab kev txhim kho siv lead ua zoo dua qub. Cov txheej txheem ntub dej tau txais mullite nrog cov khoom zoo dua li cov npe sib xws ntawm mullite tau los ntawm cov txheej txheem semi qhuav vim cov khoom txaus homogenization. Hauv kev xaiv "peb lub pob zeb" hauv cov khoom lag luam, kev xaiv ntau dua yog tsim rau cov khoom siv raw ntawm sillimanite thiab rhodochrosite.
2. Granularity

Thaum tsim cov khoom tshiab, kev saib xyuas yuav tsum tau them rau particle loj tis. Txawv particle loj distributions cuam tshuam rau kev ua tau zoo ntawm cov khoom. Cov tsoos peb - theem cov khoom xyaw ntawm ntxhib, nruab nrab, thiab nplua tsis haum lawm. Nyob rau hauv lub ntiaj teb niaj hnub no uas nanotechnology tau siv rau kev siv tshuab thiab lub neej txhua hnub, cov khoom xyaw rau cov khoom siv refractory yuav tsum tau xaiv nyob rau hauv ntau theem, raws li lub hauv paus ntsiab lus ntawm nruj packing kom ntau li ntau tau, kom tau ib tug tuab lub cev. Qhov tsawg kawg nkaus yuav tsum tau muab qhab nia yog plaub theem: ntxhib, nruab nrab, nplua, thiab nplua. Nyob rau tib lub sijhawm, qhov loj me ntawm cov khoom siv raw yuav tsum ua kom tsis tu ncua, nrog rau txhua qhov me me ntawm cov khoom, thiab sim ua raws li lub hauv paus ntsiab lus ntawm kev ntim khoom nruj.

3. Kub

Kev xaiv ntawm calcination kub yog ib qho tseem ceeb heev los xyuas kom meej ib tug nruj daim ntawv cog lus ntawm lub matrix thiab cov aggregate. Tseem muaj ntau yam ntxwv ntawm "San Shi" uas yuav tsum tau tshawb nrhiav thiab siv ntxiv, xws li thermal poob siab tsis kam, CO tsis kam, hluav taws xob rwb thaiv tsev, thiab lwm yam. Hauv cov ntsiab lus, qhov no yog tus sau cov kev paub hauv kev txhim kho thiab kev siv ntawm "Peb Lub Pob Zeb". Nrog rau kev nkag siab ntxiv ntawm "Peb Lub Pob Zeb", nws yuav muaj kev txhim kho ntau dua thiab lub luag haujlwm yav tom ntej, thiab kev cia siab ntawm kev ua lag luam yuav dav dua.
