Refract Tribs rau CDQ
3.4.1 Lub Caij Txias Teb: Chav B Mullite Bricks QBM
3.4.2 Inclined Cheeb Tsam: Chav kawm mullite-silicon carbide Qat
3.4.3 End-cia ntu, sab qaum ntawm cov plua plav, muab faib phab ntsa: Chav kawm ib mullite cibeve qab
3.4.4 Lub khob hliav rooj sov rauv qhov ncauj: chav kawm b mullite-silicon carbide cib xoo no qb
3.4.5 sab sauv ntawm cov ntu npaj ua ntej, qis dua ntawm cov plua av nqus: QN53 tuab av nplaum cib
3.4.6 mus tas li txheej, ntsaws txoj hlua: Qn3
Cov ziab qhuav qhuav muaj cov khoom siv ua ntej-cia, ib cheeb tsam ramp thiab ib qho txias. Lawv tau faib rau hauv lub nroog loj, nruab nrab thiab qis dua ntawm cov cub tawg quenching. Cov ziab qhuav qhuav yog qhov sib txuas nrog txoj kev sib nrug sib nrug. Lub plhaub sab nraud yog ua los ntawm cov phaj hlau thiab hlau ntu, thiab cov txheej sab hauv yog tsim nrog cov cib sib txawv. Qee ntu yog ua los ntawm refractory castables.
Sab qaum ib sab ntawm lub rooj sib sau ua ntej yog lub khob khob sab saum toj, nruab nrab yog ib ntu ncaj qha cib av, thiab qis dua yog ib qho puag ncig. Nws tau muab faib ua ob txheej ntawm alasonry, sab hauv phab ntsa thiab phab ntsa sab nraud, thiab sab hauv phab ntsa yuav tsum muaj lub zog sab hauv lub zog refractory cib.
Qhov yuav tsum tau ua rau cov thwv cib puab hauv qhov chaw nce zog yog: thermal poob siab kuj, siab lub zog, thiab coj tsis kam. Vim li no, Mullite-Sic cib tau xaiv. Tib yam yog qhov tseeb rau cov cib refractory ntawm kev nkag ntawm cov cub tawg.
Cov khoom lag luam
Lub refractory cib hauv chav ua ntej ntawm chav ua ntej ntawm cov cua sov qhuav muaj qhov loj me thermal poob siab. Cov kev cuam tshuam txhua yam thiab hnav ntawm cov Coke thauj khoom yuav tsum muaj siab, hnav-resistant siab, thiab thermally poob siab-resistant cov ntaub ntawv, xws li mullite cib; Chav txias txias tau hloov qhov kub thiab txias dua, yog li zoo thermal poob siab kuj yog qhov tseem ceeb tshaj plaws rau cov ntaub ntawv refactory.
Hauv kev ua haujlwm ib puag ncig ntawm cov cub tawg kom qhuav rau cov khoom siv ua kom qhuav, cov khoom siv refractory yuav tsum muaj cov yam ntxwv zoo:
(1) Cov cua sov tsis kam.
(2) Hnav tsis kam thiab siab zog (lub zog ua kom muaj zog, lub zog ntawm lub zog).
