Mullite castable yog tsim rau siv nyob rau hauv industrial kiln linings ntawm ib tug kub ntawm 1400 degree.
Mullite castables muaj qhov yooj yooj yim thiab ruaj khov ua haujlwm kub. Nyob rau nruab nrab thiab siab kub, aluminium thiab silicon reacts rau daim ntawv mullite, uas ua ke los txhim kho thiab txhim kho qhov yooj yim ntawm cov castables. Mullite castables kuj muaj qhov zoo thermal shock tsis kam, tuaj yeem tiv taus kev ntxhov siab ntawm qhov kub thiab txias, thiab muaj cov slag siab, tiv taus yaig thiab infiltration ntawm high-temperature slag.
Mullite refractory castable muaj qhov zoo fluidity thiab plasticity, ua kom yooj yim rau kev tsim thiab tsim. Thaum lub sij hawm tsim kho, nws tuaj yeem ua rau lub sijhawm tsim kho thiab txhim kho kev tsim khoom. Nrog thermal stability thiab zoo thermal rwb thaiv tsev kev ua tau zoo, nws tuaj yeem txhim kho cov thermal efficiency ntawm lub cub tawg hauv ob sab phlu thiab txo cov roj noj.
Mullite castable yog tsim rau siv nyob rau hauv ntau yam muaj kiln linings, tshwj xeeb tshaj yog nyob rau hauv lub combustion chaw nres nkoj ntawm lub cub tawg. Vim nws txoj kev ua tau zoo thiab muaj zog yas, nws cov nyhuv siv tau zoo dua li lwm cov ntaub ntawv ntawm castable, tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias qis dua 1400 degree, cov nyhuv yog pom tseeb dua. Tsis tas li ntawd, cov duab thiab cov qauv ntawm mullite yog ib lub cev siv lead ua rhombic, nrog cov pob zeb uas muaj nyob rau hauv kab ntev, koob, thiab cov saw hlau. Koob zoo li mullite yog interspersed nyob rau hauv cov khoom los tsim ib tug muaj zog moj khaum rau cov khoom siv casting.
Mullite castable yog high-end refractory castable nyob rau hauv castable series. Nws kuj tseem tuaj yeem siv los ua cov khoom sib xyaw refractory castables nrog corundum thiab silicon carbide, kom ua kom muaj kev sib koom ua ke ntawm cov txheej txheem kub kub ntawm mullite, thiab tau txais cov microstructure zoo thiab thermal poob siab. Mullite castable kuj tseem tuaj yeem ua rau hauv prefabricated burner cib, uas tuaj yeem tiv thaiv kev yaig thiab yaig ntawm cua thiab hluav taws kub hauv cheeb tsam burner.
