Lub ntsiab siv ntawm Refractory cib!

Refractory bricks yog refractory ceramic blocks siv rau hauv ob sab phlu furnaces, kilns, fireboxes, thiab qhov cub. Refractory bricks feem ntau yog tsim los tiv taus qhov kub thiab txias, tab sis feem ntau yuav tsum muaj thermal conductivity tsawg kom txuag tau lub zog. Cov cib ntom ntom feem ntau yog siv rau hauv cov ntawv siv nrog cov khoom siv hluav taws xob, tshuaj lom neeg, lossis kev ntxhov siab, xws li sab hauv ntawm cov ntoo hlawv cov kilns lossis cov rauv, qhov chaw uas lawv raug hnav thiab rhuav tshem ntawm ntoo, melting ntawm tshauv lossis slag, thiab kub kub. Cov phom sij ntom muaj qhov siab thermal zoo, uas qee zaum muaj txiaj ntsig zoo vim tias lawv tuaj yeem khaws cov txiaj ntsig kub, xws li thaum hluav taws tau tua hauv lub cub pizza.
Kiln bricks yog tsim los ntawm firing av nplaum raws li nyob rau hauv lub kiln kom txog thaum lawv ib nrab vitrify thiab kuj yuav glazed rau tshwj xeeb hom phiaj. Refractory bricks feem ntau muaj 30-40 feem pua ​​alumina, nrog rau cov ntaub ntawv tseem ceeb feem ntau yog clinker thiab lwm yam ntaub ntawv. Kev siv siab kub nce nrog qhov nce ntawm alumina cov ntsiab lus, thiab cov cib cib nrog cov ntsiab lus alumina ntawm 80 feem pua ​​lossis siab dua tuaj yeem tsim tau. Tsawg-density refractory bricks yog ib qho kev xaiv zoo hauv lwm qhov kev xav tau tsawg dua, xws li cov nkev nkev nkev, qhov uas cov cib ntxeem tau feem ntau hu ua rwb thaiv tsev cib.
Lawv tsis muaj zog, tab sis sib dua, yooj yim rau kev tsim, thiab muaj kev rwb thaiv tsev zoo dua li cov cib ntom ntom. Nyob rau hauv cov ntaub ntawv no, lawv thermal mass yog tsawg thiab yog li ntawd tsis tuaj yeem siv los khaws cov cua sov. Insulating bricks muaj thermal shock kuj zoo dua li ntom refractory bricks, tab sis lub ntsiab drawback yog lawv cov tsis muaj zog. Lub thermal rwb thaiv tsev ntawm cov cib no feem ntau yog los ntawm perlite lossis vermiculite. Zoo li cov cib ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ci cib Feem ntau yog Qib 23-1260 degree C.
