Topower piav dab tsialumina silica cibyog, lawv ua li cas nyob rau hauv lub cub tawg tiag tiag, thiab yog vim li cas lawv tseem yog ib qho kev daws teeb meem rau kiln thiab furnace linings nyob rau hauv ntau yam industries.
Dab tsi yog Alumina Silica Cib?
Ib qho alumina silica cib yog ib hom zoo li cov cib refractory feem ntau yog tsim los ntawm Al₂O₃ (alumina) thiab SiO₂ (silica). Los ntawm kev kho cov ntsiab lus alumina, manufacturers tuaj yeem tsim cov alumina silica refractory cib nrog cov yam ntxwv sib txawv uas haum rau ntau yam kev siv.
Cov ntsiab lus ntawm alumina yog li ntawm 30% mus rau 65%, tso cai rau cov cib no los txuas qhov sib txawv ntawm cov tsoos fireclay cib thiabsiab alumina cib.Qhov sib npaug sib npaug no muab alumina silica cib ib qho kev sib xyaw ua ke ntawm refractoriness, mechanical zog, thiab thermal stability.
Vim li cas Alumina Silica Bricks raug nqi -zoo
Los ntawm tus neeg yuav khoom qhov kev xav, alumina silica cib muab qhov kev pom zoo ntawm kev ua tau zoo thiab tus nqi. Piv nrog rau siab -alumina cib lossis cov khoom siv hluav taws xob siab tshaj plaws, alumina silica firebricks muab kev pabcuam zoo rau lub neej ntawm tus nqi pheej yig dua.
Cov txiaj ntsig tseem ceeb ntawm tus nqi muaj xws li:
Tus nqi nruab nrab raw khoom
Mature manufacturing technology
Muaj dav thiab ruaj khov khoom
Tsawg nqi installation thiab txij nkawm
Rau ntau qhov chaw kiln thiab qhov cub uas tsis muaj kev tawm tsam loj heev, alumina silica cib muab kev ua tau zoo txaus yam tsis muaj qhov tsim nyog tshaj - engineering.
Cov yam ntxwv ua tau zoo hauv Kilns thiab Furnaces
1. Kev ruaj khov Refractoriness hauv qab Load
Alumina silica cib tuav cov txheej txheem kev ncaj ncees nyob rau hauv tas li siab -kev ua haujlwm kub, feem ntau mus txog 1350-1550 degree, nyob ntawm cov ntsiab lus alumina. Qhov no ua rau nws tsim nyog rau cov phab ntsa ntawm lub cub tawg, lub plhaub kiln, thiab tsis yog- thaj chaw kub kub tseem ceeb.
2. Zoo Thermal Shock Resistance
Lub alumina -silica microstructure tso cai rau cov thermal expansion, pab alumina silica cib tiv thaiv rov qab cua sov thiab cua txias voj voog yam tsis muaj kev tawg ntau dhau. Cov cuab yeej no tseem ceeb tshwj xeeb tshaj yog nyob rau hauv batch kilns thiab cov cua sov sib cuam tshuam.
3. Txhim khu kev siv tshuab muaj zog
Nrog rau qhov tsim nyog txias crushing lub zog thiab abrasion tsis kam, alumina silica cib ua tau zoo nyob rau hauv qhov chaw raug cov neeg kho tshuab kev nyuaj siab, cov khoom them nqi, los yog flue gas ntws.
4. Tshuaj Compatibility
Alumina silica cib qhia tau hais tias muaj kev tiv thaiv zoo rau qhov tsis muaj zog acidic thiab nruab nrab cua, ua rau nws tsim nyog rau cov cement kilns, txiv qaub kilns, ceramic kilns, thiab cov khoom siv dav dav.
Cov ntawv thov ntawm Alumina Silica Cib
Ua tsaug rau nws cov versatility, alumina silica cib yog dav siv hauv:
Cement rotary kilns (preheater thiab hloov chaw)
Txiv qaub kilns thiab ncej kilns
Ceramic thiab sanitary ware kilns
Thaum tshav kub kub kho cua sov
Muaj boilers thiab incinerators
Tsis yog -ferrous hlau furnaces nrog nruab nrab slag raug
Rau ntau daim ntawv thov no, alumina silica cib muab lub neej ntev kev pab cuam thaum khaws tag nrho cov nqi refractory tswj.
Yuav Ua Li Cas Xaiv Txoj Cai Alumina Silica Cib
Thaum muab alumina silica cib, cov neeg yuav khoom thoob ntiaj teb yuav tsum ntsuas ntau yam tseem ceeb:
1. Alumina Cov ntsiab lus
Cov ntsiab lus alumina siab dua feem ntau txhim kho refractoriness thiab lub zog, tab sis kuj nce nqi. Kev sib piv alumina feem pua rau kev ua haujlwm kub yog qhov tseem ceeb.
2. Bulk Density and Porosity
Higher density and controlled porosity contribute to better mechanical strength and thermal stability.
3. Kev tsim khoom zoo
Uniform firing, tswj grain loj tis, thiab zoo ib yam tshuaj muaj pes tsawg leeg yog cov cim ntawm txhim khu kev qha alumina silica cib kev ua tau zoo.
4. Daim Ntawv Thov Kev Paub
Cov neeg muab khoom siv nrog cov kev paub dhau los hauv kev siv lub tshuab ua hluav taws xob thiab lub tshuab hluav taws xob tuaj yeem muab cov lus pom zoo tshaj plaws.
Vim li cas Alumina Silica Bricks tseem nrov thoob ntiaj teb
Txawm hais tias kev txhim kho cov khoom siv refractory siab heev, alumina silica cib tseem ua rau muaj ntau yam kev siv. Qhov laj thawj yog qhov yooj yim: nws ua haujlwm ntseeg tau raws li kev ua haujlwm tiag tiag thaum tus nqi tseem tshuav - ua haujlwm tau zoo.
