Kev tshuaj xyuas qhov zoo thiab qhov tsis zoo ntawm cov khoom siv refractory: kev txiav txim siab rau kev xaiv thiab kev siv
Raws li cov khoom siv tshwj xeeb, cov khoom siv refractory tau siv dav hauv cov txheej txheem kub. Txawm li cas los xij, cov khoom sib txawv refractory muaj lawv tus kheej qhov zoo thiab qhov tsis zoo ntawm kev ua haujlwm thiab kev siv. Kab lus no yuav txheeb xyuas qhov zoo thiab qhov tsis zoo ntawm cov khoom siv refractory los pab cov neeg nyeem xaiv zoo dua thiab siv cov refractories.
Ua ntej, qhov zoo: zoo heev kub tsis kam, ua kom cov txheej txheem stability
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov khoom siv refractory yog lawv qhov kub thiab txias tsis kam. Cov khoom siv refractory feem ntau yog ua los ntawm cov khoom siv kub kub ruaj khov, xws li alumina, magnesium oxide, thiab lwm yam. Cov khoom no tuaj yeem tswj xyuas qhov ruaj khov ntawm cov qauv ntawm qhov kub thiab txias, tiv thaiv thermal expansion thiab thermal shock, thiaj li ua kom muaj kev ruaj ntseg ntawm cov khoom. txheej txheem kub. Tsis tas li ntawd, cov khoom siv refractory kuj muaj cov tshuaj tiv thaiv zoo, tuaj yeem tiv taus cov kua qaub thiab alkali thiab lwm yam corrosive media, txuas ntxiv lub neej kev pab cuam.

Disadvantages: kuj tsis tshua muaj zog txhua yam, yooj yim rau hnav thiab puas
Piv nrog rau cov ntaub ntawv dav dav, lub zog txhua yam ntawm cov khoom siv refractory yog qhov tsawg. Qhov no yog txiav txim los ntawm cov txheej txheem tsim khoom thiab cov khoom siv raw khoom ntawm cov khoom siv refractory. Hauv cov txheej txheem kub kub, cov khoom siv refractory raug cuam tshuam rau yam xws li hnav, poob siab thiab kev co, ua rau tawg thiab puas. Tsis tas li ntawd, cov thermal conductivity ntawm cov khoom refractory feem ntau tsis zoo, thiab cov cua sov conduction qeeb, uas yuav cuam tshuam rau kev ua haujlwm ntawm cov txheej txheem.
Thib peb, qhov zoo: ntau hom khoom sib txawv, yoog raws li kev xav tau sib txawv
Cov khoom siv refractory muaj ntau hom khoom, tuaj yeem ua tau raws li qhov xav tau ntawm cov txheej txheem kub sib txawv. Raws li cov txheej txheem sib txawv, cov khoom sib txawv ntawm cov khoom siv refractory tuaj yeem xaiv, xws li refractory bricks, refractory castables, refractory coatings, thiab lwm yam. Txhua yam khoom muaj kev ua tau zoo thiab kev siv ntau yam, thiab tuaj yeem xaiv thiab siv raws li qhov xwm txheej tiag tiag. Qhov kev sib txawv no ua rau cov khoom siv refractory muaj zog yoog raws thiab yoog raws hauv cov txheej txheem kub.
Plaub, qhov tsis zoo: tus nqi siab, yuav tsum xav txog kev lag luam
Piv nrog rau cov ntaub ntawv zoo tib yam, tus nqi ntawm cov khoom refractory yog siab dua. Qhov no feem ntau yog vim cov khoom siv raw khoom siab ntawm cov khoom siv refractory, cov txheej txheem ntau lawm thiab lwm yam. Thaum xaiv thiab siv cov khoom siv refractory, nws cov kev ua tau zoo thiab kev lag luam yuav tsum tau txiav txim siab dav. Rau qee lub sijhawm nrog cov txheej txheem kub siab, qhov zoo ntawm cov khoom siv refractory tuaj yeem tshaj lawv cov nqi, tab sis rau qee lub sijhawm txheej txheem, kev lag luam yuav dhau los ua qhov tseem ceeb rau kev xav.
Cov khoom siv refractory muaj qhov zoo ntawm qhov kub thiab txias tsis kam thiab ntau hom khoom, uas tuaj yeem ua kom ruaj khov ntawm cov txheej txheem kub thiab ua tau raws li qhov xav tau ntawm cov txheej txheem sib txawv. Txawm li cas los xij, nws lub zog tsis tshua muaj zog thiab cov nqi siab tsis zoo kuj yuav tsum tau xav txog. Hauv kev xaiv thiab siv cov khoom siv refractory, nws yog ib qho tsim nyog yuav tsum xav txog nws cov kev ua tau zoo, kev lag luam thiab cov txheej txheem tiag tiag kom ua tiav cov txiaj ntsig zoo.
