What is the effect of the brick joints between refractory cib?

Lub cib pob qij txha ntawm refractory bricks tsis tsuas yog muab ib tug channel rau kev nkag mus thiab yaig ntawm high-temperature molten slag nyob rau hauv lub lag luam, tab sis lub slag yaig nws tus kheej kuj txhawb kev nruam nce ntawm cib pob qij txha. Ob qhov teebmeem no ua rau muaj kev sib cuag ntawm cov slag thiab sab ntawm cov cib refractory, yog li ntawd sab ntawm cov cib refractory bears ntau dhau kev ntxhov siab thaum txhua lub shrinkage thiab expansion voj voog los ntawm tshav kub. Lub slag corrodes lub cub tawg cib tsis tau tsuas yog raws lub radial kev taw qhia ntawm refractory cib nyob rau hauv cov kab nrib pleb, tab sis kuj nyob rau hauv ib ncig ntawm nws. Tshwj xeeb tshaj yog thaum muaj lub nplhaib tawg ntawm sab ntawm lub pob zeb refractory, lub nplhaib yaig nrawm dua, ua rau lub ntsej muag ntawm cov cib refractory tev tawm zoo li lub thaiv. Yog li ntawd, cov kab nrib pleb ntawm cov pob zeb refractory muaj kev cuam tshuam ntau dua rau lub neej ntawm cov cib refractory tshaj li cov kab nrib pleb.
