Khoom Taw qhia

Khoom Description

Thaum zirconia muaj cov khoom zoo xws li kev kub siab, tsis tshua muaj thermal conductivity, thiab tsis kam mus rau corrosion, nws siv nyob rau hauv blast furnace linings yog txwv los ntawm tej yam xws li nws cov nqi, susceptibility rau tej hom tshuaj tiv thaiv, thiab muaj ntau haum thiab. cov khoom siv hluav taws xob muaj txiaj ntsig zoo tsim tshwj xeeb rau cov xwm txheej hnyav ntawm qhov cub tawg. Yog li ntawd, lwm cov ntaub ntawv refractory uas zoo dua raws li qhov yuav tsum tau ua ntawm blast furnace ua haujlwm feem ntau yog xaiv rau daim ntawv thov no.

Zirconia Bricks for Blast Furnaces

Blast furnaces yog cov qauv loj siv rau kev tsim cov hlau thiab hlau los ntawm kev txo cov hlau ore nrog coke thiab limestone. Cov xwm txheej huab cua hauv lub qhov cub tawg, suav nrog qhov kub thiab txias, thaj chaw tshuaj lom neeg hnyav, thiab kev ntxhov siab, yuav tsum muaj cov ntaub ntawv refractory nrog cov khoom tshwj xeeb uas yuav tsis ua raws li cov yam ntxwv ntawm zirconia cib. Hloov chaw, cov ntaub ntawv refractory zoo li fireclay cib, silica cib, magnesia-carbon cib, thiab alumina-silicate cib feem ntau yog siv rau hauv qhov cub tawg vim lawv muaj peev xwm tiv taus qhov hnyav.

Cov yam tseem ceeb uas yuav tsum tau xav txog thaum xaiv cov ntaub ntawv refractory rau blast furnace linings muaj xws li:

Thermal Resistance:Blast furnaces ua haujlwm ntawm qhov kub siab heev, thiab cov khoom siv refractory yuav tsum tau tiv taus qhov kub thiab txias yam tsis muaj degradation tseem ceeb.

Resistance rau Corrosion:Lub tshuab hluav taws xob qhov chaw ib puag ncig muaj cov pa phem thiab cov tshuaj lom neeg uas tuaj yeem tua cov kab refractory. Cov khoom siv refractory xaiv yuav tsum tiv taus cov khoom corrosive.

Mechanical Strength:Lub refractory hauv ob sab phlu yuav tsum tiv taus txhua yam kev ntxhov siab los ntawm qhov hnyav ntawm tus nqi, thermal expansion, thiab lwm yam yam tsis muaj kev tawg lossis tsis ua haujlwm.
