Cov xim ntawm silica mullite cib muaj qee qhov kev sib raug zoo nrog qhov kub thiab txias, tab sis qhov tseem ceeb tshaj plaws yog qhov hluav taws kub kub. Thaum lub sij hawm tua hluav taws, qhov txo qhov cua yog qhov tsim nyog tshaj plaws rau kev tua ntawm silica mullite refractory cib..
Yog tias qhov hluav taws kub kub nyob hauv qhov chaw oxidizing, lub cib yuav oxidize, cov txheej saum npoo yuav tsis muaj kev cuam tshuam silicon carbide, thiab lub zog yuav txo. silica mullite cib yog tus cwj pwm los ntawm kev hnav tsis kam thiab zoo seismic stability, thiab feem ntau yog siv nyob rau hauv kev hloov chaw ua ntej thiab tom qab cement rotary kilns.
1. silica mullite cib muaj cov qauv ntom ntom
Qhov no silica series cib teeb qauv, ruaj khov mullite thiab sic muaju, thiab tuaj yeem tiv thaiv yaig los ntawm cov roj av thiab molten cov khoom siv. Txawm li cas los xij, silicon carbide muaj cov thermal conductivity, me me thermal expansion coefficient, thiab zoo thermal thiab poob siab, yog li cov cib tsis yooj yim rau tawg thiab tev tawm. Kev ua tau zoo ntawm silica mullite cib siv hauv cov cement rotary kilns kuj zoo dua li anti-flaking high-alumina cib thiab phosphate high-alumina cib nrog zoo hnav tsis kam.
2. Qhov chaw tua hluav taws ntawm lub cib no txawv ntawm qhov siab ntawm alumina cib.
Txawm li cas los xij, nyob rau hauv ntau zaus, qhov hluav taws kub cua ntawm silica mullite cib txawv ntawm qhov siab ntawm alumina cib los yog magnesia cib, vim hais tias carbon silicide yog tsim rau firing nyob rau hauv ib tug txo qhov cua. Nyob rau hauv ib qho chaw oxidizing, silicon carbide yog oxidized, thiab siv cov nyhuv yuav zoo heev. txo. Qee cov tuam ntxhab yuav ntxiv qee qhov kev faib ua feem ntawm cov hlau txhuas hmoov los kho cov oxidation ntawm silicon carbide hauv cov txheej txheem tsim khoom. Txawm li cas los xij, thaum lub sijhawm tua hluav taws, qhov chaw tua hluav taws yuav tsum tau tswj kom zoo. Cov nyhuv silicon carbide ntawm silica mullite cib raug rho tawm haujlwm hauv qhov chaw txo qis ua rau pom qhov pom tseeb. Thiab thaum siv los ua ib txheej hauv cov cement rotary kiln, nws tuaj yeem tiv thaiv cov yaj los ntawm kev sib sau.
Nws yuav tsum tau muab sau tseg tias tus nqi ntawm silicon carbide ntxiv kuj cuam tshuam cov xim ntawm cov silica mullite cib. Thaum tus nqi ntawm silicon carbide ntxiv me me, cov tshuaj tiv thaiv ntawm lub cib saum npoo yog me me. Thaum cov nyiaj tsawg dua 8%, lub cib saum npoo yeej ua rau me ntsis. , tsuas yog ib txheej ntawm me ntsis discoloration. Tsis muaj nto glaze tshwm. Yog tias qhov kub thiab txias dhau lawm, cov tshuaj tiv thaiv saum npoo yuav tsis hloov ntau. Tab sis qhov tseem ceeb tshaj plaws yog qhov cuam tshuam ntawm kev tua hluav taws ntawm cov xim ntawm silica molybdenum cib. Tau kawg, kev ua haujlwm kuj yuav raug txo thaum siv.
