Hauv cov khoom siv coke qhuav quenching, siv covrefractory cibcov ntaub ntawv tseem ceeb. Lawv tsis tsuas yog cuam tshuam nrog kev ua haujlwm ntawm cov cuab yeej siv, tab sis tseem cuam tshuam ncaj qha rau kev tsim khoom ruaj ntseg thiab cov khoom zoo. Cov hauv qab no yog cov ncauj lus kom ntxaws txog kev siv cov khoom siv refractory hauv cov khoom siv coke qhuav quenching:
1. Txheej txheem cej luam ntawm qhuav coke quenching li
Cov khoom siv coke qhuav quenching feem ntau yog tsim los ntawm lub qhov cub qhuav qhuav, lub tshuab nqus plua plav, lub rhaub dej, lub tshuab nqus plua plav, cov khoom siv coke tawm thiab cov kiv cua ncig. Ntawm lawv, lub qhov cub qhuav quenching yog cov khoom siv tseem ceeb. Nws masonry belongs rau ib tug ntsug kiln qauv. Nws yog cylindrical upright masonry nyob rau hauv ib tug zoo siab lub xeev. Lub tshuab hluav taws xob lub cev tau muab faib ua ntu ua ntej khaws cia, thaj chaw ramp thiab seem cua txias los ntawm sab saum toj mus rau hauv qab.
2. Kev siv cov khoom siv refractory thiab kev ua tau zoo
Ua ntej cia seem
Sab saum toj lub khob hliav qab sab saum toj: Qhov no muaj qhov kub thiab txias hloov ua ntej thiab tom qab thauj khoom coke, thiab tseem raug coj los ntawm coke. Yog li ntawd, mullite-silicon carbide masonry nrog zoo yaig kuj, hnav tsis kam, ceev ceev txias thiab cua sov kuj thiab siab flexural zog yog xaiv.
Khoom refractory cib masonry nyob rau hauv nruab nrab ncaj seem: kom tiv thaiv thermal expansion generated los ntawm kev thauj khoom ntawm coke liab, nrog rau kev cuam tshuam thiab hnav ntawm coke, A-hom mullite cib nrog lub zog siab, hnav tsis kam, thiab ua haujlwm zoo. ceev txias thiab cua sov yog xaiv rau masonry.
Lower annular flue: Nws tau muab faib ua ob lub annular masonry ntawm sab hauv phab ntsa thiab sab nrauv phab ntsa. Sab hauv phab ntsa yuav tsum tiv taus qhov cuam tshuam thiab hnav ntawm coke, thiab tseem yuav tsum tiv thaiv kom tsis txhob muaj qhov sib txawv ntawm qhov sib txawv ntawm qhov chaw cia khoom ua ntej thiab cov hluav taws xob annular. Yog li ntawd, A-hom mullite cib nrog grooves thiab nplaig kuj siv rau masonry.
Inclined channel cheeb tsam
Lub cib nyob rau hauv inclined channel cheeb tsam yog cantilevered txheej los ntawm txheej los txhawb lub load ntawm lub sab sauv masonry. Qhov kub thiab txias feem ntau hloov pauv, thiab cov pa roj circulating nqa coke plua plav los ua qhov hnyav ntawm qhov no. Yog li ntawd, mullite thiab silicon carbide cib nrog zoo thermal shock kuj, hnav tsis kam thiab flexural kuj raug xaiv rau masonry.
Qhov cua txias
Txawm hais tias qhov ncaj seem refractory cib masonry ntawm cov cua txias seem muaj cov qauv yooj yim, nws sab hauv phab ntsa refractory firebrick masonry yog ib qho ntawm qhov tsis zoo tshaj plaws vim nws yuav tsum tiv taus qhov hnyav hnyav thaum lub coke ntws mus. Yog li ntawd, B-hom mullite bricks nrog lub zog siab, hnav tsis kam, thiab kev ua haujlwm zoo rau kev txias txias thiab cua sov yog xaiv.
Lwm qhov tseem ceeb
Rauv lub qhov ncauj: Siv B-hom mullite silicon carbide cib thiab mullite silicon carbide hluav taws av nplaum.
Cov khoom siv plua plav tseem ceeb: Xav txog ob qhov kev yaig thiab hnav ntawm cov pa roj thiab cov hmoov coke, muaj zog hnav tsis kam thiab zoo tiv thaiv kom txias thiab cua sov sai.
Chav txias: Siv B-hom mullite cib, cov av nplaum ntom ntom, cov av nplaum hluav taws kub thiab cov castables hnav-resistant.
Lwm qhov chaw kub kub: Siv cov khoom hnyav-aluminium castables thiab lub teeb yuag high-aluminium castables.
III. Kev ua tau zoo ntawm cov khoom siv refractory
Mullite cov khoom: muaj cov tshuaj zoo stability, me me thermal expansion tus nqi, muaj zog thermal shock stability, thiab muaj zog tiv thaiv acid thiab alkali slag yaig. Nws qhov kub-kub kauv deformation tsis kam yog ntau dua li lwm cov high-aluminium bricks nrog rau tshwj xeeb high-aluminium cib, thiab nws cov high-temperature kev ua tau zoo yog piv rau qee yam khoom ntawm silicon, magnesium, thiab corundum khoom.
Silicon carbide khoom: Nws muaj qhov zoo ntawm kev hnav tsis kam thiab corrosion kuj, siab kub lub zog, siab thermal conductivity, me me linear expansion coefficient, thiab zoo thermal shock kuj. Tab sis qhov tsis zoo yog tias nws yooj yim rau oxidize ntawm qhov kub thiab tsis haum rau kev siv hauv qhov chaw oxidizing.
IV. Kev ceev faj rau kev siv cov khoom siv refractory cib
Tus qauv tsim: Txhim kho cov qauv tsim ntawm thaj tsam ramp thiab tsim nyog faib cov kev txhawb nqa bearing siab los xyuas kom meej lub peev xwm txias ntawm coke thiab qhov ua tau zoo ntawm cov kabmob cheeb tsam ntawm lub bracket.
Masonry qauv: Thaum tso cov ntaub ntawv refractory rau qhov qhuav quenching rauv, kev tswj nruj yuav tsum tau ua, cov qauv masonry yuav tsum tau ua kom tiav, lub masonry ntawm flue flat arch ring beam yuav tsum tau ua kom zoo, thiab lub ntiajteb txawj nqus ntawm cov khoom txhawb nqa yuav tsum. muab tusyees faib kom nws sib npaug.
Kev ua haujlwm system: Txhim kho cov txheej txheem kev ua haujlwm, tswj kev ua haujlwm ruaj khov, txo qhov sib txawv ntawm cov khoom siv hauv qhov cub, tuav lub ntim coke kom ruaj khov, thiab xyuas kom cov khoom zoo sib xws.
Gas-to-material ratio: Siv cov khoom siv roj-rau-cov khoom sib piv kom txo tau qhov kev tiv thaiv ntawm cov kab mob thiab ua kom qeeb ntawm cov refractory los ntawm airflow.
Lub Sijhawm Saib Xyuas: Txo cov sijhawm saib xyuas kom tsawg kom ua tiav qhov txias ntawm cov coke liab hauv CDQ qhov cub kom ntseeg tau tias thermal tshuav nyiaj li cas thiab txo qhov kev puas tsuaj los ntawm thermal expansion thiab contraction ntawm refractory.
Hauv cov ntsiab lus, kev xaiv thiab siv cov khoom siv refractory hauv CDQ chav tsev yog ib txoj haujlwm tsim nyog, uas yuav tsum tau teeb tsa tsim nyog raws li kev ua haujlwm thiab kev ua haujlwm ntawm cov khoom sib txawv. Nyob rau tib lub sijhawm, kev saib xyuas yuav tsum tau them nyiaj rau kev tiv thaiv thiab kev saib xyuas cov ntaub ntawv refractory kom ntev lawv lub neej kev pabcuam thiab txhim kho kev ua haujlwm ntawm CDQ chav tsev.
