Dab tsi yog cov ntaub ntawv refractory hauv ob sab phlu rau txhua qhov ntawm lub qhov cub tawg kub qhov cub tawg?

Lub refractory configuration tsom xam ntawm txhua feem ntawm lub qhov cub tawg kub blast qhov cub yog sib koom los ntawm refractory cib manufacturers.

Lub qhov cub tawg kub lub qhov cub tawg yog lub tshuab hluav taws xob hloov hluav taws xob, feem ntau yog muab cov cua kub cua kub ib puag ncig rau cov cua kub ntawm lub qhov cub tawg kom ua tiav cov cua kub ua haujlwm siab, feem ntau 1200 ~ 1350 ℃. Qhov sib txuam kub blast furnaces rau blast furnaces yog 3 ~ 4. Txhawm rau kom ua tau raws li qhov yuav tsum tau muaj ntawm qhov kub thiab txias qhov chaw thiab lub sijhawm ua haujlwm ntev ntawm cov cua kub cua sov, cov khoom siv refractory rau cov cua kub cua sov yuav tsum muaj cov yam ntxwv ntawm qhov kub thiab txias tsis kam thiab siab siab ua hauj, zoo creep resistance, loj tshwj xeeb kub muaj peev xwm, thiab zoo thermal conductivity. .

Raws li cov qauv ntawm txhua qhov ntawm lub qhov cub kub blasting thiab qhov cuam tshuam ntawm lub cub tawg, cov ntaub ntawv refractory rau lub qhov cub kub kub tuaj yeem muab faib ua ob ntu: qhov kub thiab txias. Qhov kub thiab txias: nrog rau sab sauv ntawm lub combustion chamber, checker cib nyob rau sab sauv ntawm lub regenerator, loj phab ntsa cib, sab saum toj ntawm lub cub tawg, thiab lwm yam.; nruab nrab thiab qis kub qhov chaw: suav nrog rau nruab nrab thiab qis ntawm lub combustion chamber, checkered bricks ntawm nruab nrab thiab qis qhov chaw ntawm lub regenerator, loj phab ntsa cib, thiab qhov hluav taws xob qhov chaw, thiab lwm yam.

Raws li cov qauv ntawm lub qhov cub kub kub, nws tuaj yeem muab faib ua: sab saum toj ntawm lub qhov cub, phab ntsa loj ntawm lub tshuab hluav taws xob, lub checker cib, phab ntsa muab faib, phab ntsa loj ntawm lub combustion chamber, lub burner thiab lwm yam. .

1. Refractory nyob rau sab saum toj ntawm lub cub tawg:

Sab saum toj ntawm lub cub tawg yog nyob rau hauv qhov kub thiab txias nyob rau hauv lub kub moj tej tawg rauv, qhov twg cov khoom refractory ncaj qha hu rau cov cua kub thiab flue gas. Cov khoom siv refractory uas muaj zog thermal shock tsis kam thiab creep kuj yuav tsum tau xaiv. Feem ntau, silica cib thiab cov av nplaum qis tuaj yeem siv tau. High alumina cib, siab alumina rwb thaiv tsev cib, mullite cib, lub teeb av nplaum cib, andalusite cib, acid-resistant tshuaj pleev xim, av nplaum tshuaj pleev xim, thiab lwm yam.

3. Cov khoom siv refractory rau checker bricks:

Lub cheeb tsam siab kub ntawm lub checker bricks ntawm lub regenerator yuav tsum tau ua los ntawm cov ntaub ntawv refractory nrog zoo kub-kub ntim stability, corrosivity thiab creep kuj. Qhov nruab nrab thiab qis qis dua siab dua los ntawm cov khoom siv refractory sab saud. Ntxiv rau qhov ua kom txaus siab rau nws qhov kev ua tau zoo, nws tseem yuav tsum tau ua haujlwm zoo ntawm nws qhov kub thiab txias compressive zog thiab thermal shock stability.

Sab sauv ntawm cov checker bricks feem ntau siv silicon checker cib thiab high-aluminium checker cib, nruab nrab ib feem siv low-creep high-aluminium checker cib thiab high-aluminium checker cib, thiab qis qis siv low-creep high-aluminium checker. bricks thiab av nplaum checker bricks.

Tsis tas li ntawd, lub regenerator ntawm spherical kub blast qhov cub feem ntau siv cov pob refractory los hloov cov checker cib, feem ntau yog cov pob alumina refractory siab, thiab av nplaum refractory npas tuaj yeem siv rau hauv qhov chaw qis.

4. Cov khoom siv refractory rau kev faib phab ntsa:

Phab ntsa muab faib yog phab ntsa refractory cib uas cais cov regenerator thiab cov combustion chamber. Qhov siab ntawm phab ntsa muab faib feem ntau yog 400 ~ 700mm siab tshaj qhov checker cib ntawm lub regenerator kom ntseeg tau tias huab cua tsis sib xws. Vim yog qhov kub thiab txias sib txawv ntawm ob sab ntawm phab ntsa muab faib, qhov sib txawv thermal expansion ntawm phab ntsa yuav loj dua, uas ua rau cov khoom siv refractory ntawm phab ntsa muab faib rau deform, khoov thiab tawg. Yog li ntawd, silica cib thiab siab alumina cib tuaj yeem siv rau sab sauv ntawm cov khoom siv refractory ntawm phab ntsa muab faib.
