Hluav taws kub av nplaum cibfeem ntau xa mus rau hluav taws cib nrog Al2O3 cov ntsiab lus tshaj 40%, Fe2O3 2-2.5%. Cov ntaub ntawv nyoos feem ntau yog 65% -85% calcined hluav taws av nplaum, 35% -15% khi av nplaum. Cov txheej txheem tsim khoom yog feem ntau: Sib tsoo{13}} batching- sib tov-shaping nyob rau hauv siab xovxwm{17}} raug rho tawm haujlwm hauv qhov kub ntawm 1400℃- tshuaj xyuas- pob. Cov thermal ua haujlwm zoo heev. Hluav taws kub av nplaum cib yog cov tsis muaj zog acid cib, yog li alkali tsis kam yog me ntsis qaug zog, tab sis lawv muaj cov kua qaub tsis kam, siab thermal shock thiab lwm yam. Rau cov hluav taws kub zoo av nplaum cib, cov thermal shock kuj zoo dua li cov cib ci, silica cib, corundum cib thiab lwm yam.
Cov khoom siv hauv hluav taws kub av nplaum cib feem ntau yog Kaolin, kuj tseem muaj 6% -7% impurities suav nrog Sodium oxide, Potassium oxide, Ferric oxide thiab lwm yam. Sintering txheej txheem rau hluav taws kub av nplaum cib yog tsim cov txheej txheem ntawm Mullite theem. Thaum cov txheej txheem no, impurities tsim rau hauv iav theem nyob ib ncig ntawm lub mullite theem, ua rau txo qis thermal ua haujlwm. Yog li qhov tsawg impurities, qhov zoo dua.
Cov av nplaum hluav taws kub kuj tseem hu ua refractory cib, lawv tuaj yeem muab faib rau cov cib raug rho tawm haujlwm, tsis yog- cov cib raug rho tawm haujlwm, fused casting cib, thermal rwb thaiv tsev cib thiab lwm yam raws li kev tsim khoom; Raws li cov duab thiab qhov loj me, lawv tuaj yeem muab faib rau cov qauv me me, cov cib ncaj, sab cib cib, cov kab cij kawg, cov cib tshwj xeeb thiab lwm yam. Refractory hluav taws cib yog siv los ua cov khoom siv rau kub kub industrial furnaces, kilns, thiab lwm yam khoom siv kub, thiab tuaj yeem tiv taus corrosion thiab yaig nyob rau hauv qhov kub thiab txias.
Vim qhov tsis tshua muaj refractoriness thiab nws shrinkage ntawm qhov kub thiab txias, thermal conductivity rau hluav taws kub av nplaum cib yog 15% ~ 20% qis dua li ntawm silica bricks, thiab cov neeg kho tshuab lub zog kuj tsis muaj zog tshaj li ntawm silica bricks. Yog li ntawd, hluav taws kub av nplaum cib feem ntau yog siv nyob rau hauv qhov chaw thib ob ntawm coke ncu. Xws li regenerator sealing phab ntsa, me me flue hauv ob sab phlu thiab regenerator checker cib, rauv qhov rooj hauv ob sab phlu cib, lub ru tsev rauv thiab nqa cov yeeb nkab hauv ob sab phlu, thiab lwm yam.
