Qhov kub ntawm silica cib nto nyob rau hauv qhov chaw hloov pauv ntawm cov cement rotary kiln yog li ntawm 1400 degree, thiab qhov kub ntawm thaj chaw ua ntej cua sov, qhov chaw txias thiab lwm qhov chaw yog qis dua li ntawm thaj chaw hloov pauv, uas yog, thaj chaw tua hluav taws yog tiv thaiv los ntawm cov tawv nqaij ntawm qhov cub, qhov kub ntawm lub cib saum npoo tsis siab, thiab silicon mo Qhov pib kub ntawm cib softening nyob rau hauv load yog siab tshaj 1 500 degree, tshwj xeeb tshaj yog cov khoom muaj ib tug ntom qauv, uas yog tsim los ntawm cov minerals. nrog siab hardness, corundum, silicon carbide, thiab mullite. Lub zog compressive thiab load softening kub yog ho siab dua li cov anti-stripping high-alumina bricks. Nws thermal poob siab stability, corrosion kuj, hnav tsis kam, thiab thermal conductivity tsis siab, uas yuav tsum tau los ntawm cov txheej txheem ntawm lub rear hloov chaw. Lub neej yog 1.5 mus rau 2 npaug ntawm cov cib los tiv thaiv. Nws muaj kev hnav zoo thiab tsim nyog rau kev siv txias txias, thiab nws lub neej kev pabcuam tuaj yeem ncav cuag ntau tshaj ob xyoos, uas yog 3 mus rau 5 npaug ntawm siab alumina cib. Tam sim no, raws li kev siv cov khoom sib txawv ntawm qhov sib txawv ntawm lub tshuab ua teb, cov qib sib txawv ntawm silica molybdenum cib nrog cov khoom sib txawv tau siv.
Kev ua tau zoo zoo:
1. High load softness thiab zoo heev kub kub kuj (qhov tseeb nrhiav tau tus nqi ntawm nws load softening kub yog ruaj khov saum 1680 degree, uas tau zoo heev txhim kho nyob rau hauv lub hauv paus ntawm silica molybdenum bricks, uas yog piv rau cov magnesia-aluminium spinel cib. .)
2. Lub zog muaj zog, hnav tsis kam, tsis yooj yim rau tev tawm thiab corrode (tus nqi ntsuas qhov tseeb ntawm nws lub zog yog ruaj khov siab tshaj 160MPa, uas yog ntau tshaj 3 npaug ntawm lub zog ntawm silica cib Lub zog nce, nws tsis yooj yim rau kev ua. puas thaum tuav thiab kev tsim kho, thiab tuaj yeem txhim kho tag nrho Nws hnav tsis kam, yog li nws tsim nyog siv 2 mus rau 3 meters ntawm qhov cub qhov ncauj). 3. Tsawg thermal conductivity thiab thermal rwb thaiv tsev zoo (cov thermal conductivity ntawm magnesia-aluminium spinel cib loj dhau, uas ua rau kub kub hauv daim ntawv yooj yim; vim silicon molybdenum cib tseem yog high-alumina-silicon carbide series khoom, nws Cov yam ntxwv ntawm cov khoom txiav txim siab nws qis thermal conductivity, qhov yooj yim kub tuaj yeem txo los ntawm ntau tshaj 50 degree hauv tib lub sijhawm)
4. Zoo thermal poob siab tsis kam (nws zoo thermal shock stability tuaj yeem hloov kho rau ib puag ncig kev xav tau ntawm qhov kub thiab txias nyob rau hauv pem hauv ntej hloov chaw)
5. Silica cib ntom ntom yog nruab nrab, thiab qhov yooj yim thauj khoom raug txo qis (qhov ntom ntom ntawm silicon-Mohong cib yog ntau tshaj 8 feem pua qis dua li ntawm cov magnesia-aluminium spinel cib, uas ua rau txo qis ntawm qhov yooj yim load. Si-Mo liab cib los ntawm ntau tshaj 8 feem pua hauv chav tsev ntev ntawm tib hom kiln)
