Nyob rau lub Rau Hli, KEV KAWM NTAWV, 14 tons fireclay refractory cib tau ntim rau xa mus rau peb cov neeg siv khoom hauv Kaus Lim Kauslim.
Fireclay refractory bricks yog ua los ntawm 50 feem pua mos av nplaum thiab 50 feem pua cov av nplaum tawv clinker raws li ib qho me me me me tom qab kho av nkos, molding, ziab thiab ci. Qhov loj ntawm cov av nplaum zoo tib yam yog 230 * 114 * 65 (mm), thiab qhov loj ntawm T-19 av nplaum cib yog 4600 * 225 * 75 (mm). Av nplaum cib belongs rau cov khoom tsis muaj zog acid refractory, uas tuaj yeem tiv taus cov kua qaub slag thiab kua qaub yaig. Fireclay refractory bricks muaj thermal shock kev ua tau zoo thiab tiv taus cua txias thiab cua kub ceev. Fireclay refractory bricks yog dav siv nyob rau hauv loj thiab nruab nrab-qhov loj qhov cub kub blast qhov cub, hluav taws xob rauv rwb thaiv tsev txheej, blast furnace gas nqa kav thiab cua txias qhov cub linings.
Nyob rau hauv qhov kub thiab txias ntawm {{0}} degree, qhov ntim ntawm cov av nplaum zoo tshaj plaws nthuav dav nrog qhov nce ntawm qhov kub thiab txias. Lub linear expansion nkhaus zoo ib yam li ib txoj kab ncaj nraim, thiab cov linear expansion rate yog 0.6 feem pua rau 0.7 feem pua, uas tsuas yog ib nrab ntawm cov silica bricks. Thaum qhov kub nce mus txog 1200 degree thiab tom qab ntawd txuas ntxiv kom sov, nws qhov ntim yuav pib ntsws los ntawm tus nqi nthuav dav. Qhov seem shrinkage ntawm zoo av nplaum cib ua rau lub loosening ntawm masonry mortar pob qij txha, uas yog ib tug loj disadvantage ntawm av nplaum cib. Thaum qhov kub siab tshaj 1200 degree, qhov qis melting point nyob rau hauv fireclay cib maj mam yaj, thiab cov hais yog nyob ze rau ib leeg vim qhov kev txiav txim ntawm nto nro, ua rau lub ntim shrinkage.
Vim tias qhov kub ntawm cov av nplaum qis qis thiab qis qis ntawm qhov kub thiab txias, qhov thermal conductivity yog 15% ~ 20 feem pua qis dua li ntawm silica bricks, thiab cov neeg kho tshuab lub zog kuj tseem phem dua li ntawm silica cib. Yog li ntawd, av nplaum cib tsuas yog siv tau 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 lub qhov rooj hauv ob sab phlu, lub ru tsev rauv thiab nce yeeb nkab hauv ob sab phlu, thiab lwm yam.
