Rau cov cement kilns, cov khoom kim heev refractory tsis haum rau tag nrho cov kiln. Kev xaiv cov cib refractory rau txhua qhov yuav tsum ua kom haum rau kev ua haujlwm.
Muaj ntau lub hauv paus ntsiab lus rau kev xaiv cov khoom siv rau cov teb kiln:
(1) Nws yuav tsum ua kom tau raws li cov haujlwm yooj yim thaum txo qhov ntau thiab tsawg ntawm cov cib refractory.
(2) Lub neej ntev yuav tsum sib phim kom ntau li ntau tau. Piv txwv li, lub neej ntev ntawm lub qhov ncauj qhov ncauj castables, sab sauv thiab qis hloov chaw, thiab cov chaw tua hluav taws tuaj yeem sib xyaw ua ke, thiab nws yog qhov zoo tshaj yog tias lawv tuaj yeem kho tau ib zaug.
(3) Lub voj voog hloov kho yog tswj tau: xyuas kom muaj kev kho dua tshiab hauv ib xyoos thiab siv zog rau ob qho kev kho dua tshiab txhua peb xyoos.
Kev paub txog kev xaiv cov khoom siv cib refractory rau ntau qhov chaw
(1) Alkaline cib yuav tsum tau siv rau hauv qhov chaw tua hluav taws.
Alkaline cib (tsis suav nrog magnesia-alumina spinel cib) yuav tsum tau siv nyob rau hauv qhov chaw tua hluav taws, xws li ncaj qha ua ke ntawm magnesia-chrome cib, magnesia-hlau spinel refractory cib, dolomite cib, thiab lwm yam, tshwj xeeb tshaj yog magnesia-hlau spinel cib thiab dolomite cib. . Nws yog qhov zoo dua rau kev sib txuas ncaj qha rau magnesia-chromium bricks nrog cov khoom zoo thiab tus nqi qis, tab sis nws muaj qhov tsis zoo ntawm ib puag ncig siab thiab kev pabcuam luv luv.
Lub neej kev pabcuam ntawm mafic spinel bricks yog nyob nruab nrab ntawm 6 thiab 10 lub hlis, thiab tsawg heev tuaj yeem ncav cuag 12 lub hlis. Tab sis yog hais tias lub neej ncav cuag 12 lub hlis, lub neej yuav nce los ntawm tsawg kawg yog 20%, thiab yog hais tias nws muaj peev xwm ncav cuag 18 lub hlis, lub lifespan yuav nce 50%, uas yog tus nqi-zoo.
(2) Kev xaiv cov khoom siv refractory rau cov cheeb tsam sab saud thiab qis.
Muaj ntau txoj kev xaiv rau thaj tsam sab sauv thiab sab qis, xws li magnesia-alumina spinel cib, magnesia-hlau spinel refractory cib, silica-molybdenum liab cib, AZM1680 silica-molybdenum cib, thiab lwm yam. Feem ntau, magnesia-alumina spinel cib thiab magnesia. -hlau spinel bricks muaj thermal conductivity loj, qhov kub ntawm lub tog raj kheej yuav siab nyob rau hauv lub thib ob-ceev log siv, tab sis cov kev pab cuam lub neej yuav ntev dua. Yog tias koj siv cov silica-molybdenum liab cib zoo dua, qhov kub thiab txias yuav qis dua, thiab lub neej kev pabcuam tuaj yeem ncav cuag 18 lub hlis.
(3) Kev xaiv cov khoom siv hluav taws xob tiv thaiv kev nyab xeeb.
Kev xaiv cov cib refractory rau kev nyab xeeb txoj siv sia (xws li 40 m tom qab Ф4.8 m High-strength alkali-resistant bricks kav rau 1 mus rau 2 xyoo, anti-flaking siab alumina cib rau 2 mus rau 3 xyoo, thiab AZM1650 silicon molybdenum cib rau 3a5 xya.
