Cov khoom siv hluav taws xob hluav taws xob hluav taws xob siv hluav taws xob siv hauv cov hluav taws xob melting feem ntau yog siv los txo cov cua sov, txhim kho lub zog ua haujlwm ntawm lub tshuab hluav taws xob, thiab tiv thaiv cov qauv hluav taws xob los ntawm qhov kub thiab txias. Cov yam ntxwv tseem ceeb ntawm insulating lub teeb yuag refractory cov ntaub ntawv yog tsawg ntom thiab tsis tshua muaj thermal conductivity, uas muaj peev xwm zoo insulate thiab tiv taus qhov kub thiab txias ib puag ncig ntawm lub melting rauv.
Dab tsi yog cov khoom siv hluav taws xob refractory hnav thiab lawv cov yam ntxwv?
1. Lub teeb yuag siab alumina cib: Ua los ntawm high-alumina bauxite, nrog tsawg ntom thiab zoo thermal rwb thaiv tsev kev ua tau zoo. Piv nrog rau cov zoo tib yam high-alumina cib, nws cov thermal conductivity yog tsawg, uas tuaj yeem txo qhov kub poob.
Haum rau cov phab ntsa ntawm lub cub tawg, lub cub tawg sab saum toj thiab lwm qhov chaw ntawm lub qhov cub melting uas xav tau kev rwb thaiv tsev. Haum rau siv nyob rau hauv qhov kub thiab txias ib puag ncig, nws tuaj yeem muab cov nyhuv thermal rho tawm zoo.
2. Lub teeb yuag Silica: ua los ntawm cov ntaub ntawv xws li Silica thiab av nplaum, nws muaj tsawg thermal rwb thaiv tsev ua haujlwm. Lub thermal conductivity ntawm silica bricks yog tsawg, uas tuaj yeem tiv thaiv kom tsis txhob muaj cua sov los ntawm dissipating sab nraud.
Siv rau lub qhov cub sab saum toj, lub cub tawg phab ntsa thiab lwm qhov chaw ntawm lub qhov cub melting uas xav tau kev rwb thaiv tsev zoo. Silica bricks muaj tshuaj zoo stability thiab haum rau nruab nrab thiab qis kub melting rauv.
3. Lub teeb yuag refractory castables: muaj li ntawm lub teeb yuag refractory aggregates (xws li lub teeb yuag perlite, ceramsite, thiab lwm yam) thiab binders, nrog zoo heev plasticity thiab thermal rwb thaiv tsev zog. Castables tuaj yeem muab pov rau ntawm qhov chaw thiab tsim nyog rau cov txheej txheem rwb thaiv tsev ntawm cov duab nyuaj.
Haum rau rwb thaiv tsev ntawm cov duab complex xws li linings, ru tsev thiab phab ntsa ntawm melting furnaces. Kev tsim kho yooj yim tuaj yeem txo qhov kub poob.
4. Lub teeb ci ntsa iab refractory: ua los ntawm lub teeb liab insulating, thiab lwm yam) rwb thaiv tsev thiab cov cua sov rwb thaiv tsev. Feem ntau siv rau qhov cub hluav taws xob rwb thaiv tsev nyob rau hauv qhov chaw kub kub.
Dav siv nyob rau hauv lub cub tawg phab ntsa, ru tsev, linings thiab lwm qhov chaw ntawm melting furnaces, zoo insulate thiab txo tshav kub.
5. Aluminium silicate fiber ntau cov khoom: Aluminium silicate fibers muaj qhov ntom ntom thiab thermal conductivity, thiab muaj cov thermal rwb thaiv tsev zoo heev. Cov khoom siv fiber ntau tuaj yeem ua rau hauv daim pam, daim hlau, thiab lwm yam, uas yooj yim rau kev tsim.
Siv rau lub tshuab hluav taws xob lub cev, lub qhov cub hluav taws xob thiab lub qhov cub hluav taws xob ntawm lub qhov cub tawg thiab lwm qhov chaw uas xav tau kev rwb thaiv tsev. Haum rau ib puag ncig uas yuav tsum tau nruj me ntsis ntawm thermal rwb thaiv tsev nyhuv.
6. Perlite refractory khoom: Perlite yog ib qho intumescent refractory lub teeb yuag rwb thaiv tsev cov ntaub ntawv uas zoo thermal rwb thaiv tsev thiab kub tsis kam. Lub thermal conductivity ntawm cov khoom perlite yog tsawg thiab tuaj yeem ua kom sov.
Siv rau hauv ob sab phlu thiab cub hluav taws xob rwb thaiv tsev txheej ntawm lub melting rauv. Cov khoom siv perlite feem ntau siv nyob rau hauv qhov chaw qis thiab nruab nrab kub thiab tuaj yeem muab cov nyhuv thermal rho tawm zoo.
