Hnav resistant castables yog tsim los ntawm siab - hardness silicon carbide, corundum, hwm bauxite, mullite refractory aggregates thiab hmoov, siab - lub zog binders, thiab additives. Lawv feem ntau yog tsim los rau siab - kub thiab hnav tsis kam, thiab yog siv rau hauv ob sab phlu uas xav tau siab flexural thiab compressive zog nyob rau hauv siab - qhov kub thiab txias ib puag ncig.
Rau hnav resistant castables siv nyob rau hauv circulating fluidized txaj boilers nyob rau hauv lub hwj chim nroj tsuag, lawv yog feem ntau formulated nrog fused corundum, thiab tej zaum ib tug tej feem ntawm dub silicon carbide yog ntxiv. Lub binder yog ntshiab calcium aluminate cement nrog silica hmoov.
Yog tias nws siv rau hauv ob sab phlu ntawm alumina ncua kev kawm calcining rauv, silicon carbide tsis tuaj yeem ntxiv; Hloov chaw, sintered dawb corundum los yog fused alumina yuav tsum tau ntxiv rau hauv ib qho kev faib ua feem. Yog tias nws yog siv rau tapping trough ntawm lub qhov cub cua sov, sub-dawb corundum thiab xim av corundum yuav tsum tau ntxiv. Rau cov hmoov, fused alumina hmoov yog siv, thiab rau cov hmoov micro, zircon micro hmoov yog siv.
Yog tias siv ntawm qhov kub siab tshaj 1500 degree, nws tuaj yeem ua rau hauv cov blocks precast. Los ntawm kev ntxiv qee qhov ntawm SiC rau cov blocks precast, cov cib precast rau kev thov tuaj yeem ua tau, uas tsis yog tsuas yog ua kom yooj yim rau kev tsim kho, tab sis kuj tseem txhim kho qhov kub ntawm - qhov kub thiab txias.
