Kub kub resistant refractory cib rau Kilns, furnaces

Raws li cov khoom sib txawv ntawm refractory cib, lawv tuaj yeem muab faib ua tsib pawg, xws li: silicon-alumina series refractory cib, alkaline series refractory cib, carbon-muaj refractory cib, zirconium-muaj refractory cib, thiab tshav kub-insulating refractory cib.

Txhua lub cub tawg tsis yog tsim nrog ib hom refractory cib xwb, nws xav tau kev sib xyaw ntawm cov refractory cib sib txawv.

(1) Silica cib xa mus rau refractory cib uas muaj ntau tshaj 93% SiO2, uas yog cov hom tseem ceeb ntawm cov kua qaub refractory cib.Nws yog tsuas yog siv rau masonry coke ncu, tab sis kuj rau lub vaults thiab lwm yam load-bearing qhov chaw ntawm thermal kilns ntawm ntau yam iav, ceramics, carbon calciners, thiab refractory cib.Nws yog siv rau hauv cov khoom siv thermal hauv qab 600 ° C thiab nrog qhov kub thiab txias hloov pauv.

(2) Cov av nplaum.Av nplaum cib yog tsim los ntawm mullite (25% mus rau 50%), iav theem (25% mus rau 60%), thiab cristobalite thiab quartz (txog 30%).Feem ntau, cov av nplaum tawv yog siv los ua cov khoom siv raw, clinker yog calcined ua ntej thiab tom qab ntawd tov nrog cov av nplaum mos.Ib qho me me ntawm cov iav dej, cov cement, thiab lwm cov ntaub ntawv tseem tuaj yeem muab ntxiv los ua cov khoom tsis raug kub hnyiab thiab cov khoom tsis zoo.Nws yog feem ntau siv refractory cib nyob rau hauv blast furnaces, kub blast qhov cub, cua sov rauv, fais boilers, txiv qaub kilns, teb kilns, ceramics, thiab refractory cib firing kilns.
(3) High-alumina refractory cib.Cov ntxhia muaj pes tsawg leeg ntawm high-alumina refractory cib yog corundum, mullite, thiab iav theem.Cov ntaub ntawv raw yog high-alumina bauxite thiab sillimanite ntuj ore, thiab tseem muaj fused corundum, sintered alumina, hluavtaws mullite, thiab clinker calcined nrog alumina thiab av nplaum nyob rau hauv sib txawv proportions.Nws feem ntau yog tsim los ntawm txoj kev sintering.Tab sis cov khoom tseem muaj xws li fused cam khwb cia bricks, fused cib, unburned cib, thiab unshaped refractory cib.High alumina refractory bricks yog dav siv nyob rau hauv hlau thiab steel kev lag luam, non-ferrous hlau kev lag luam, thiab lwm yam lag luam.(4) Corundum refractory cib, corundum cib xa mus rau ib hom refractory cib nrog AL2O3 cov ntsiab lus tsis tsawg tshaj li 90% thiab corundum raws li lub ntsiab theem, uas yuav muab faib ua sintered corundum cib thiab fused corundum cib (5) High- alumina tshav kub-insulating lub teeb yuag refractory cib.Nws yog insulating lub teeb refractory cib nrog bauxite raws li lub ntsiab AL2O3 cov ntsiab lus tsis tsawg tshaj li 48%.Cov txheej txheem ntau lawm txais cov txheej txheem ua npuas ncauj, thiab cov txheej txheem hlawv tawm kuj tseem siv tau.High-alumina tshav kub-insulating lub teeb yuag refractory cib tuaj yeem siv los tsim cov cua sov-insulating txheej thiab qhov chaw uas tsis muaj qhov muaj zog kub-kub kub molten khoom yaig thiab scouring.Thaum nyob rau hauv kev sib cuag ncaj qha nrog cov nplaim taws, qhov kub ntawm qhov chaw ntawm cov high-alumina heat-insulating refractory bricks yuav tsum tsis txhob siab tshaj 1350 ℃.Mullite tshav kub-insulating refractory cib tuaj yeem hu ncaj qha rau cov nplaim hluav taws thiab muaj cov yam ntxwv ntawm qhov kub thiab txias tsis kam, siab zog, thiab zoo kawg nkaus lub zog txuag.Nws yog tsim rau hauv ob sab phlu ntawm lub qhov cub pyrolysis, kub moj tej tawg rauv, ceramic roller kiln, hluav taws xob porcelain tub rau khoom kiln, thiab ntau yam tsis kam rauv.(6) Clay heat-insulating lightweight refractory bricks yog cov cua sov-insulating refractory cib nrog AL2O3 cov ntsiab lus ntawm 30% mus rau 48% ua los ntawm cov av nplaum refractory ua cov khoom tseem ceeb.Nws cov txheej txheem ntau lawm txais cov txheej txheem kub hnyiab thiab ua npuas ncauj.Siv cov av nplaum refractory, ntab hlaws, thiab refractory av nplaum clinker ua raw cov ntaub ntawv, ntxiv binder thiab sawdust, los ntawm batching, mixing, molding, drying, thiab firing, cov khoom nrog ib tug ntau ntom ntawm 0.3 mus rau 1.5g / cm3 yog tau.Cov zis ntawm av nplaum hluav taws kub-insulating cib tso nyiaj rau ntau tshaj li ib nrab ntawm tag nrho cov zis ntawm cov hluav taws kub-insulating refractory cib.
