Silicon Mullite cib

Silica Cib

Silica-Mullite cib, lub hom tshiab ntawm hnav refractory refraction brick, muaj cov coj tsis kam tsib zaug siab dua li ntawm phosphate-alumina cib. Hais txog nws lub cev muaj pes tsawg leeg, nws yuav tsum yog cov khoom lag luam uas silicon-mullite, xa mus rau silica-mullite cib. Cov npe no feem ntau yog cov neeg nyiam ua lag luam hauv tsev, thiab lwm yam kev lag luam feem ntau hu nws High-alumina carlicon caricon carlicon carbide cib.

Silica-mullite cib yog ib qho 1203- si {2}} sic refractory thiab silicon carbide raws li lub ntsiab raw khoom. Nws lub nra ua softening kub, thermal poob siab kuj, kev tawm tsam tsis kam thiab kev yaig kuj zoo dua li cov cib ntau dua, thiab txawm tias zoo dua li spinel cib. Tam sim no, Silica-Mullite Cib siv nyob rau yuav luag txhua feem ntawm Cement Castary Cotary Canary.

 

Qhov ntom ntawm Silica-Mullite Cib yog qhov tseem ceeb heev. Cov khoom lag luam zoo siab tuaj yeem inhibit oxidation ntawm sic thiab txhim kho cov kev ua tau zoo ntawm silica-mullite cib. Lub particle muab qhab nia ntawm cov av nkos muaj qhov cuam tshuam ncaj qha rau ntawm cov khoom lag luam. Txhawm rau kom tau txais cov khoom lag luam siab, cov feem pua ​​feem pua ​​ntawm feem pua ​​ntawm ntau qhov ntau thiab tsawg rau xam raws li lub dinger-funk mis. Tom qab ntawd, feem pua ​​ntawm particle loj muaj pes tsawg leeg tau muab suav raws li cov khoom siv raw, thiab tsim nyog tau hloov kho cov kev sim kom tau cov particle kev tsim khoom.

Phosphoric acid-cov khoom lag luam tsis yog tsuas yog muaj lub zog tuab thiab muaj zog, tab sis kuj tseem muaj lub siab refdicaliness nyob rau hauv thauj thiab zoo hnav tsis kam.

Kev tsim khoom ntawm silicon carbide mullite los ntawm silicon carbide thiab high-alumina bauxite bauxite clinker yog nyob rau hauv kab nrog thev naus laus zis ntawm refractory cib cov khoom. Txij li thaum Silicon carbide yog oxidized los ua silicon diocide, yog li cov khoom tiv thaiv zoo li cov khoom siv ntawm cov zaub mov zoo nkauj, yog li ntawd tuaj yeem ua kom muaj cov ntsiab lus ntawm silicon Li no txhim kho lub thermal poob siab, hnav tsis kam thiab corrosion tsis kam ntawm cov khoom. Qhov kev pab cuam lub neej ntawm kev muaj zog thiab tuab silicon-molybdenum breaks tshwj xeeb lub tog raj kheej yog 3 mus rau 4 npaug ntev dua li ntawm cov qoob loo ntau dua.

Cov ntawv thov loj ntawm silicon-molybdenum cib refractory ntau dua thiab muaj kuab lom thiab tshuaj lom neeg ntawm cov ntaub ntawv refractory. Yog li ntawd, tsuas yog rau thaj chaw tua hluav taws ntawm lub Molly Clock, thiab cov txiaj ntsig kev hloov pauv ntawm silica, thiab cov nyhuv hloov pauv tau zoo dua li magnesia-chrome cib.

(1) Cov khoom muaj cov qauv tuab thiab hnav zoo.

Lub ntsiab Crystal theem ntawm silicon-moulded refractory breaks yog muaj ntawm high-hardness 9.}. 5), 0-7. 5). Cov qauv ntawm cov khoom lag luam yog ntom heev, nrog ib qho ntom ntom, nrog ib qho ntom ntom feem ntau ntawm 2.7 thiab 3. {{14} g / cm3. Nrhiav cov ntaub ntawv refractory network thiab hais txog cov ntaub ntawv. Qhov ntsuas kub ib txwm coj tsis kam ntawm cov ntaub ntawv refractory nyob ntawm nws lub zog thiab cov qauv ntom ntom. Cov ntaub ntawv nrog lub zog siab thiab qhov ceev tau hnav tsis kam. Cov CLING ntawm Cement Quary Rotary Rotary Lower Kev sib txhuam rau lub sijhawm ntev, thiab hnav yog ib qho tseem ceeb rau kev puas tsuaj ntawm ob sab. Qhov ceev, lub zog thiab hnav tsis kam ntawm silicon-moulded refractory cib yog qhov zoo dua li cov ntawm kev tawm tsam cov cib thiab magina-alumina spinnel cib cib. Silica-pwm r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r recractory tau zoo nyob rau hauv Cement qeeb qeeb lab, txoj siv sia rau kev lim hiam thiab lwm qhov chaw. Nws tuaj yeem hais tau tias zoo hnav tiv thaiv kev ua si lub luag haujlwm tseem ceeb heev.

(2) Siab thauj softening kub thiab kev kub siab zoo.

Lub load softening kub ntawm silica-molybdenum cib yog siab dua 1450 degree, thiab siab tshaj plaws yog siab dua 1650 degree. Muaj qee yam sib txawv hauv cov khoom softening kub ntawm cov khoom ntawm cov hom sib txawv. Refractory Cib qhov cub ntawm qhov cub sib txawv ntawm cov cement catary catn hauv ob sab sib txawv. Qhov ntsuas kub ntawm thaj chaw tua hluav taws thiab thaj chaw tom ntej yog muaj kev tiv thaiv los ntawm cov tawv nqaij hauv nruab nrab, qhov chaw hluav taws kub yog}}}}} degree). Lub load softening kub teev cov pob zeb no tseem tshaj li kev siv cov kab mob siab ntau dua-alumphate high-alumina refraction kub yog {{8} degree).

Piv nrog cov chaw tua hluav taws, qhov kev hloov chaw yog yooj yim cuam tshuam los ntawm kev txo cov cua thiab kev tiv thaiv tshav kub vim nws tsis muaj tshuaj tiv thaiv cov tawv nqaij. Nws cov kev pabcuam lub neej yeej ib txwm yog ib qho teeb meem blockleneck rau Caent Canary Rotary Canary. Yog li ntawd, qee cov nroj tsuag xis mas siv cov khoom lag luam magnesium-alumina spinel cov khoom hauv thaj chaw hloov chaw. Raws li kev tshawb fawb ntawm Magnesium-Alagnesium cib siv nyob rau hauv ib qho chaw qhib, tab sis vim yog cov Corrosion Alkali Cov qhov cub kub ntawm lub refractory cib mus tev tawm thiab tawg, ua rau muaj kev puas tsuaj rau hauv ob sab phlu. Txawm li cas los xij, vim lub qauv ntom ntom nti ntawm silicon-molybdenum cib refractory cov cib, tshwj xeeb tshaj yog cov khoom siv ntom nti tsim nyob rau saum npoo ntawm cov khoom siv refraction, nws txwv tsis pub cov khoom nkag. Ib qho ntxiv, cov tshuaj tshuaj ntawm A1203, Sic, thiab Sio2 yog ruaj khov nrog roj av, thiab lawv tsis muaj zog ua kom haum. Qhov thib ob, silicon-molybdenum cib muaj zoo thermal poob taus. Txij li thaum Silica-Molybdenum cib muaj qee qhov nyiaj ntawm sic, nws yog qhov zoo tshaj plaws thermal nthuav dav cov thermal poob siab loj ntawm cov khoom. Qhov 1100 degree dej txias kev sim yog ntau tshaj 10 zaug, thiab qhov siab tshaj yog 46 zaug. Yog li no, Molybdenum cib siv nyob rau hauv Maas Rotary Milns tsis tev tawm lossis tawg, uas tuaj yeem txhim kho lawv lub neej pabcuam.

Txo cov dej kub thiab txias thiab muaj cov cua sov kev ua haujlwm zoo. Lub thermal conductivity ntawm silica-molybdenum cib cib [2. {}. 74}}. 74}}. 74}} Silica-Molybdenum Cib yog siv nyob rau hauv theem pib hluav taws, Kiln Tail, cov huab cua sov thiab lwm qhov ntawm cov loj qeeb qeeb. Piv nrog alkaline cib, qhov tseeb kub ntawm lub tog raj kheej yog txo los ntawm ntau tshaj 100 degree.

Qhov kub ntawm Thermal Promansion tus nqi tuaj yeem pom zoo los ntawm ob tog.

Nco tseg: Cov kev cai ua haujlwm ntawm cov khoom tshwj xeeb yuav tsum tau pom zoo los ntawm ob tog.
