Tsawg Maas casabetablePuas yog cov khoom siv refractory feem ntau, thiab ua kom cov hmoov av alumina muaj qhov cuam tshuam tseem ceeb rau nws cov kev ua tau zoo:
1. Txhim kho lub zog: Ua kom Alumina hmoov muaj cov khoom zoo thiab thaj chaw tshwj xeeb thaj chaw, uas tuaj yeem sau cov pores hauv cov nrib thiab ua kom nws cov qauv denser. Thaum lub sij hawm sib xyaw ua ke thiab tawv tawv ntawm lubast, cov hmoov kuj tseem tuaj yeem cuam tshuam nrog lwm cov khoom siv kom tsim lub zog tshiab hauv cov khoom loj, yog li kev txhim kho lub zog ntawm cov Castable. Piv txwv li, ntxiv qhov tsim nyog ntawm lub ntsej muag alumina hmoov rau ib lub corundum qis sastable tuaj yeem nce nws chav chav sov compressive lub zog los ntawm 20% {}}}%.
2. Txhim Kho Lub Pleev: Ib qho tsim nyog ntawm Alumina hmoov tuaj yeem ua lub pob nyem uas tsis tshua muaj, li kev txhim kho cov kua ntawm cov Castable. Qhov no ua rau nws yooj yim dua rau lubast los sau cov khoom ua pwm thiab cov qauv sib dhos thaum kev tsim kho, ua kom zoo dua qub. Txawm li cas los xij, yog tias cov hmoov ntau dhau yog ntxiv, lub agglomeration nruab nrab ntawm cov khoom yuav ua rau muaj kev ntxhov siab, uas yuav txo cov fluab ntawm cov Castable.
3. Txhim khu lub rhaub dej poob siab: cov hmoov ntxiv tuaj yeem kho cov qauv grain ntawm cov qauv sib dhos ntawm cov muaju loj. Thaum cov Castable yog raug hloov mus rau qhov hloov qhov kub thiab txias tau zoo dua rau cov kev hloov pauv ntawm kev ntxhov siab thiab nthuav dav, thiab txhim kho lub thermal poob siab ntawm cov Castable. Piv txwv li, tom qab ntxiv ua kom Alumina hmoov rau qee qhov kev pabcuam kom muaj cua sov siv rau cov cua sov kom txias thiab cua sov tau txuas ntxiv.
4. Txo Porosity: Ua kom Alumina hmoov tuaj yeem sau cov porees ntawm cov cement tsis tshua muaj zog, txo cov pores thiab li ntau qhov porosity ntawm lub Castable. Sab qab porosity tuaj yeem txhim kho lub zog, corrosion tsis kam thiab coj kev tiv thaiv ntawm cov Castable. Piv txwv li, tom qab ntxiv kom alumina hmoov rau cov hlau nplaum qis-cement casastrastet, nws porosity tuaj yeem txo los ntawm 5% {%.
Qhov sib ntxiv ntawm cov hmoov alumined tuaj yeem txhim kho cov kev ua tau zoo, thiab cov qauv tsim kho kom meej, thiab cov khoom siv xeb ntau dhau los ntawm kev ntxiv mus ntxiv.
Yog tias muaj cov kev cai tshwj xeeb lossis kev ntsuas ntxiv tuaj yeem ua tau rau kev kho kom haum cov mis kom ua tiav kev ua tau zoo.
