Qhov teeb meem no peb yuav qhia ntxiv txog kev faib cov hluav taws xob rwb thaiv tsev hluav taws kub cib rau iav kilns.
3. av nplaumlightweight rwb thaiv tsev hluav taws cib. Nws yog cov khoom siv rwb thaiv tsev refractory ua los ntawm cov av nplaum refractory nrog Al2O3 cov ntsiab lus ntawm 30% ~ 48%. Nws cov txheej txheem ntau lawm adopts hlawv tawm ntxiv txoj kev thiab ua npuas ncauj txoj kev. Av nplaum hluav taws xob rwb thaiv tsev hluav taws cib muaj ntau yam kev siv, feem ntau yog siv los ua cov ntaub ntawv rwb thaiv tsev ntawm cov txheej txheem rwb thaiv tsev nyob rau hauv ntau yam kev lag luam kilns uas tsis tuaj rau hauv kev sib cuag nrog cov ntaub ntawv molten. Nws ua haujlwm kub yog 1200 ~ 1400 ℃.
4. Aluminium oxide rwb thaiv tsev cib. Cov khoom muaj hluav taws kub tsis kam thiab zoo thermal shock kuj, thiab feem ntau yog siv los ua cov txheej txheem kub kub rau cov kilns. Nws ua hauj lwm kub yog 1350-1500 ℃, thiab ua hauj lwm kub ntawm high-purity khoom yuav ncav cuag 1650-1800 ℃. Nws yog refractory rwb thaiv tsev cov khoom ua los ntawm raw cov ntaub ntawv ntawm fused corundum, sintered alumina, thiab muaj alumina.
5. Lightweight mullite cib. Thermal rwb thaiv tsev thiab refractory khoom ua los ntawm mullite raws li lub ntsiab raw khoom. Mullite rwb thaiv tsev bricks muaj qhov kub thiab txias tsis kam, siab zog, tsis tshua muaj thermal conductivity, thiab tuaj yeem nkag mus rau hauv kev sib cuag nrog cov nplaim taws, thiab lawv tsim nyog rau hauv ob sab phlu ntawm ntau yam kev lag luam kilns.
6. Aluminium oxide hollow pob cib. Aluminium oxide hollow pob cib yog siv rau kev siv mus sij hawm ntev hauv qab 1800 ℃. Nws muaj cov tshuaj zoo stability thiab corrosion kuj ntawm kub kub. Piv nrog rau lwm cov rwb thaiv tsev lub teeb ci ci, alumina hollow pob cib muaj qhov kub thiab txias ua haujlwm ntau dua, muaj zog dua, thiab qis thermal conductivity. Nws qhov ntom ntom kuj yog 50% ~ qis dua li cov khoom siv tsis zoo ntawm tib qho kev sib xyaw ua ke, thiab tuaj yeem tiv thaiv qhov cuam tshuam ntawm cov nplaim taws kub.
