Thermal conductivity ntawm refractory cib (thermal conductivity)

Thermal conductivity (thermal conductivity) ntawm refractory bricks, uas yog, nws muaj peev xwm mus hloov tshav kub, feem ntau yog qhia nyob rau hauv cov nqe lus ntawm thermal conductivity. Thermal conductivity yog hais txog tus nqi ntawm tshav kub dhau los ntawm ib cheeb tsam nyob rau hauv ib chav tsev lub sij hawm thiab ib chav tsev kub gradient nyob rau hauv tus txheej txheem ntawm lub zog hloov. Cov thermal conductivity ntawm cov khoom sib txawv feem ntau txawv heev. Nyob rau hauv chav tsev kub, qhov thermal conductivity ntawm ntau yam refractory cib tuaj yeem nyob ntawm ob peb feem pua ​​​​rau ntau kaum (w / (m· ℃)), thiab qhov sib txawv ntawm tus nqi siab tshaj thiab tus nqi qis tshaj yog ze li ib txhiab zaus. Raws li qhov kub thiab txias, qhov sib txawv thermal conductivity ntawm ntau yam refractory cib yuav txo qis, tab sis qhov sib txawv tseem loj heev. Piv txwv li, ntawm 1000 ℃, thermal conductivity ntawm lub teeb silica tsuas yog hais txog 0.35W / (m·℃); recrystallized silicon carbide khoom yog hais txog 17.5W / (m·℃); graphite tuaj yeem siab li 35W / (m·℃).
