Raws li cov cuab yeej ntawm kub blast furnaces yuav ntau thiab ntau mature, qhov yuav tsum tau raurefractory bricksnyob rau hauv kub moj tej tawg furnaces tau dhau los ua nruj me ntsis, tshwj xeeb tshaj yog nyob rau hauv lub high-temperature cheeb tsam. Qhov kub ntawm lub cub tawg yog siab txog 1300 degree. Yog li ntawd, piv txwv li, lub sab sauv ntawm lub regenerator thiab lub combustion chamber yog feem ntau raug rau yaig los ntawm high-temperature gas, uas ua rau lawv yooj yim rau kev puas tsuaj, ncaj qha cuam tshuam rau kev siv cov nyhuv thiab lub neej ntawm kub blast furnace. Yog li ntawd, txoj kev loj hlob ntawm lub neej ntev kub kub blast furnace refractory hluav taws cib tau dhau los ua lub hom phiaj ntawm kev sib koom tes ntawm cov kws tshaj lij thiab cov kws tshawb fawb hauv kev lag luam refractory. Hauv kev ua haujlwm engineering tiag tiag, muaj ntau hom hluav taws kub refractory cib siv nyob rau hauv kub moj tej tawg rauv masonry, raws li qhia hauv qab no:
01 Tsawg creep series Qhov no series ntawm refractory cib yog tsuas yog tsawg creep siab alumina cib thiab tsawg creep av nplaum cib siv nyob rau hauv kub blast furnaces. 1) Tsawg creep av nplaum cib rau kub moj tej tawg furnaces yog ua los ntawm high-zoo av nplaum clinker raws li lub ntsiab raw khoom, tsim los ntawm kev kub siab thiab sintered ntawm kub. Cov khoom muaj lub siab load softening kub, zoo tsis kam mus rau nruab nrab kub creep, thiab zoo cuam tshuam kuj. Nws yog cov khoom tseem ceeb refractory rau qhov qis thiab nruab nrab ntawm qhov kub ntawm qhov cub tawg. 2) Tsawg creep siab alumina cib yog cov ntaub ntawv qib siab refractory ua los ntawm qib tshwj xeeb bauxite, fused corundum thiab fused mullite ua cov ntaub ntawv tseem ceeb. Cov khoom muaj cov yam ntxwv ntawm siab refractoriness, siab load softening kub thiab muaj zog slag kuj.
02 Silica cib rau kub blast furnaces Silica cib rau kub blast furnaces yog siliceous refractory khoom nrog tridymite ua lub ntsiab siv lead ua theem. Lawv tsuas yog tsim nyob rau hauv qhov kub thiab txias qhov chaw ntawm blast furnace kub blast furnaces. Kub moj tej tawg rauv silica bricks muaj kub qhov chaw xws li ruaj khov ntim, tsis muaj creep, zoo thermal shock kuj thiab zoo tshuaj corrosion kuj.
03 Andalusite cib rau kub blast furnaces Andalusite cib rau kub moj tej tawg furnaces yog high-qib refractory cib ntawm silicon-aluminium refractory cov ntaub ntawv, uas muaj zoo heev thermal shock stability thiab creep kuj. Lawv feem ntau yog siv rau hauv qhov tseem ceeb xws li cov qhov hluav taws kub kub thiab cov qhov rooj kub blasting.
04 High-aluminium rwb thaiv tsev cib rau kub blast furnaces High-aluminium rwb thaiv tsev cib yog tsim los siv cov txheej txheem ua npuas ncauj. Lawv muaj qhov zoo ntawm qhov ntim tsawg, siab compressive zog, siab load softening, me me qhov ntev kam rau ua, thiab zoo heev thermal stability. Lawv tuaj yeem txhim kho thermal efficiency, txo kev siv hluav taws xob, txhim kho kev ua haujlwm, thiab txhim kho kev tsim khoom, thiab ua tiav cov txiaj ntsig kev lag luam. Lawv tsuas yog siv nyob rau hauv rwb thaiv tsev txheej ntawm kub blast furnaces. Raws li cov kev ua haujlwm tiag tiag ntawm ntau qhov chaw ntawm lub qhov cub kub kub, xaiv txoj cai refractory cib ntau yam yog ib txoj hauv kev zoo heev los txuas ntxiv kev pab cuam lub neej ntawm lub cub tawg kub.
