Dab tsi yog qhov txawv ntawm cov refractory cib thiab lub teeb ci ci?

Lub luag haujlwm tseem ceeb ntawm lub teeb ci ci yog khaws cov rwb thaiv tsev kub, txo cov cua sov, thiab txhim kho thermal efficiency. Nws yog ib qho kev tshawb fawb thiab kev siv hluav taws xob txuag hluav taws xob uas tuaj yeem ua kom qeeb ntawm cov cua sov hloov mus.

Ntawm cov ntaub ntawv refractory, lub teeb ci ci thiab cov cib refractory (tsis muaj thermal rwb thaiv tsev cov khoom) yog cov khoom siv refractory uas tau siv dav. Txawm li cas los xij, muaj qhov sib txawv loj ntawm lub teeb ci ci thiab cov cib refractory.

1, kev txuag hluav taws xob

Lub thermal conductivity ntawm lub teeb ci ci feem ntau yog 0.2 ~ 0.4 (qhov nruab nrab kub 350 ± 25 ℃) w / mk, thiab thermal conductivity ntawm refractory cib yog ntau dua 1.0 (qhov nruab nrab kub 350 ± 25 ℃) w / mk. Yog li ntawd, thermal rwb thaiv tsev ntawm lub teeb ci ci Kev ua tau zoo dua li cov cib refractory.

2, hluav taws kub tsis kam

Qhov hluav taws kub tsis kam ntawm lub teeb ci ci feem ntau qis dua 1400 ℃, thiab qhov hluav taws kub tsis kam ntawm cov cib refractory yog siab tshaj 1400 ℃.

3, ceev

Qhov ceev ntawm lub teeb ci ci yog 0.8-1.0g / cm3, thaum qhov ceev ntawm refractory bricks yog siab tshaj 2.0g / cm3.

Feem ntau hais lus, lub teeb ci ci tsis tuaj yeem raug hluav taws xob ncaj qha, kub kub melts thiab tshuaj lom neeg gases. Raws li cov ntaub ntawv sib txawv thiab lub cev thiab tshuaj lom neeg, cov cib refractory tuaj yeem siv los tiv thaiv ntau yam kev yaig ntawm cov nplaim hluav taws ncaj qha ci thiab cov ntaub ntawv kub kub hauv qhov cub.

Los ntawm qhov pom ntawm qhov kev siv, kev siv ntau zaus ntawm cov cib refractory yog ntau dua li cov cib sib sib zog nqus. Txawm li cas los xij, nyob rau xyoo tas los no, nrog rau kev paub txog kev tiv thaiv ib puag ncig thiab kev txuag hluav taws xob thiab kev siv cov khoom siv hluav taws xob siab thermal, lub teeb ci ci kuj tau siv dav hauv kev yuav khoom ntawm kiln masonry. Tshwj xeeb, muaj ntau yam tshiab ntawm lub teeb ci ci: lub teeb yuag mullite cib, lub teeb yuag high-alumina cib, thiab lub teeb av nplaum cib.
