Cov kev ua haujlwm thiab cov yam ntxwv tawg ntawm ntau txoj haujlwm hauv lub qhov cub kub kub yog qhov sib txawv, thiab cov kev ua haujlwm ntawm lub cev thiab tshuaj lom neeg ntawm cov refractory castables siv kuj txawv. Lub qhov cub kub kub nrog castables tuaj yeem muab faib ua qhov kub thiab txias ntawm ob qhov chaw loj. Thaum qhov kub ntawm huab cua kub qis dua 900 degree, feem ntau siv av nplaum cib masonry; Thaum cov cua kub siab tshaj 900 degree, lub qhov cub hauv ob sab phlu thiab lattice bricks nyob rau hauv high-temperature feem siv high alumina cib, mullite castables, silica bricks thiab siliceous castables.
Qhov kev thov rau refractory castables rau blast furnace thiab kub moj tej tawg qhov cub yog loj thiab loj, thiab muaj ib tug nyiam ntawm hloov refractory bricks maj mam. Cov ntaub ntawv thiab cov khoom siv raw siv hauv castables yog tib yam li cov pob zeb refractory, thiab kev tsim kho yog ceev, thiab kev pab cuam lub neej yog loj dua li ntawm refractory bricks.
Xws li lub thermal stability ntawm lub ru tsev cib yuav tsum tau them tshwj xeeb mloog mus rau, nyob rau hauv thiaj li yuav zam heev heev kev hloov nyob rau hauv kub thiab spalling los yog tawg cib thaiv lub daim phiaj qhov; incineration chamber thiab cua sov cia chav tsev sab sauv yuav tsum muaj ib tug high-temperature structural zog, tsawg re-burning kab shortening, anti-slagging, thiab lwm yam., thiaj li yuav tsis txhob kub-kub deformation ntawm lub incineration chamber, tilting thiab lattice bricks, xws li raws li kev poob qis, lattice qhov teeb meem. Lub lattice cib kuj yuav tsum tau ua kom zoo thermal conductivity, muaj peev xwm loj thaum tshav kub kub, kev nqus cua sov thiab tso cua sov yog qhov ceev ceev. Cov kev cai no yuav tsum tau ua raws li qib cua kub ntawm lub qhov cub kub.
Lub ru tsev qhov cub kub yog lub qhov cub kub nyob rau hauv qhov kub thiab txias, qhov chaw ntawm lub ru tsev ntawm cov khoom siv refractory, tshwj xeeb tshaj yog ncaj qha nrog cov cua kub thiab cov roj kub flue kov cov cib txheej, nws yog ib qho tsim nyog yuav tsum muaj cov thermal shock resistance thiab creep resistance. Nws raug nquahu kom siv silicon cib, silicon refractory castables lossis qis creep siab alumina refractories.
