1, Refractory bricks rau qhov hluav taws kub
Qhov chaw ua haujlwm ntawm cov hluav taws kub-resistant bricks yog qhov tsis zoo, thiab cov qauv tsim thiab cov neeg siv tau ceev faj heev txog lawv cov qauv tsim thiab xaiv cov khoom siv. Hluav taws kub refractory txheej: tseem hu ua kub nto cib, yog qhov kub thiab txias, corrosion-resistant consumable txheej. Feem ntau, yuav tsum muaj cov khoom siv chromium siab, uas xav tau kev kub siab tshuaj lom neeg ruaj khov, siab creep zog thiab thermal shock kuj. Qhov tuab ntawm cov thee-dej slurry gasifier los ntawm lub tog raj kheej mus rau qhov hluav taws kub yog li 230 hli. 90 chromium-aluminium-zirconium cib (high-chromium cib) yog siv. Cov khoom siv raw siv rau chromium-aluminium-zirconium cib yog Cr203 fused composite khoom nrog Cr2O3 cov ntsiab lus ntau dua 99% (stacking ntom ntau dua 5.1g / cm³) nrog ultrafine hmoov. Tom qab sib tov thiab molding, nws yog raug rho tawm haujlwm nyob rau hauv ib tug high-kub shuttle kiln. Cov khoom lag luam muaj qhov zoo ntawm cov khoom loj loj (ntau dua 4.25g / cm³), porosity tsawg (tsawg dua 16%), kub tsis kam (ntau dua 120Mpa), cov ntsiab lus tsis tshua muaj hlau oxide thiab silicon oxide thiab lwm yam impurities, cua sov zoo. . Lub zog ruaj khov, kub creep tsis kam thiab lwm yam khoom muaj nyob rau hauv txoj kab nrog cov refractories rau lub gasifier rau qhov hluav taws kub uas yuav tsum tau, yog li 90 chrome-aluminium-zirconium cib yog lub gasifier rau qhov hluav taws kub ntawm cov khoom siv refractory zoo tagnrho.
2, Rov qab txheej refractory cib
Nws lub luag haujlwm tseem ceeb yog rwb thaiv tsev kub, tab sis thaum cov cib refractory ploj, raws li hauv ob sab phlu, tuaj yeem siv rau lub sijhawm luv luv. Backing bricks feem ntau yog corundum cib. Lub thickness ntawm lub tog raj kheej refractory bricks yog hais txog 200 hli. chrome corundum bricks yog ua los ntawm cov xuab zeb dawb corundum ua aggregate thiab Cr2O3 li aggregate, uas yog tov, molded thiab sintered ntawm kub. Cov cib refractory feem ntau yog siv los ua hluav taws kub hauv lub qhov ncauj ntawm slag gasifier, carbon dub reactor thiab rov qab cib ntawm thee dej slurry gasifier.
3, rwb thaiv tsev txheej
Rwb thaiv tsev txheej xav tau zoo thermal rwb thaiv tsev kev ua tau zoo, yog li ntawd lub plhaub hlau yog ib txwm nyob rau hauv ib tug tsim nyog qhov kub thiab txias, thaum txo tshav kub poob. Feem ntau siv alumina hollow pob cib. Lub tog raj kheej firebricks yog hais txog 110 mm tuab. Aluminium hollow-pob insulating firebricks / casting cov ntaub ntawv yog tsuas yog siv rau hauv qab txheej ntawm slag hydrocarbon furnaces, carbon dub reactors thiab thee slurry furnace rwb thaiv tsev txheej.
4, Compressible txheej
Nws tuaj yeem raug compressed lossis rov qab los ntawm qhov kub thiab txias, yog li txo cov nyhuv ntawm radial thermal expansion stress ntawm lub plhaub. Lub thickness yog li 15 ~ 20mm. Feem ntau siv FBX1900 cement yog qhov sib xyaw qhuav ntawm cov ntxhia fibers thiab tsis muaj binder, uas muaj cov tshuaj tiv thaiv xeb zoo tab sis tsis muaj kev cuam tshuam corrosion. Nws tuaj yeem siv nrog rab riam av nplaum lossis txau nrog rab phom txau thaum tsim kho.
