Lub Ib Hlis 23 tonsmullite refractory cibyog packed rau xa mus rau cov neeg muas zaub nyob rau hauv Russia. High quality thiab zoo tshaj tus nqi refractory khoom nyob rau hauv Topower Refractory.
Mullite refractory cib yog tsim los ntawm cov khoom siv hluavtaws mullite. Raws li qhov yuav tsum tau muaj feem ntawm cov khoom, cov organic composite fillers yog ntxiv, thiab lawv yog nqus extruded thiab sintered nyob rau hauv high kub los tsim lub teeb yuag mullite khoom. Nrog nws lub teeb yuag thiab zoo heev thermal rwb thaiv tsev zog, mullite lub teeb yuagrefractory bricksyog dav siv nyob rau hauv kub nto refractory hauv ob sab phlu los yog rwb thaiv tsev txheej ntawm ntau yam thermal cov khoom, tsim tej yam kev mob rau kev txhim kho lub zog siv ntawm cov khoom.
Mullite lub teeb yuag refractory bricks yog high-aluminium refractory cov ntaub ntawv nrog mullite raws li lub ntsiab siv lead ua theem. Feem ntau, cov ntsiab lus alumina nyob nruab nrab ntawm 65% thiab 75%. Lub refractory kub ntawm mullite lub teeb yuag refractory cib tuaj yeem ncav cuag tshaj 1790 degree. Qhov pib kub ntawm softening nyob rau hauv load yog 1600-1700 degree . Zoo thermal shock tsis kam.
High alumina mullite refractory cib muab faib ua lub teeb thiab hnyav. Hnyav high-alumina mullite cib yog high-alumina refractory cib nrog mullite ua lub ntsiab siv lead ua theem. Cov ntsiab lus alumina yog nruab nrab ntawm 65% thiab 75%. Cov ntxhia muaj pes tsawg leeg yog mullite. Raws li ib txwm muaj, lub cev ntom ntom yog siab dua 2.5.
Mullite cib suav nrog sintered mullite cib thiab fused mullite cib.Sintered mullite cibyog ua los ntawm high-aluminium clinker li raw khoom, av nplaum ua tus neeg sawv cev, thiab zoo li tus thiab raug rho tawm haujlwm. Fused mullite cib yog ua los ntawm alumina thiab refractory av nplaum thiab raug nrum siv txoj kev txo electrofusion. Cov muaju ntawm fused mullite loj dua cov sintered mullite, thiab lawv cov thermal shock kuj zoo dua li cov khoom sintered.
Siab aluminamullite lub teeb ci ciyog ib qho ntawm cov khoom siv thermal rwb thaiv tsev refractory nrog cov qauv zoo thiab tsis tshua muaj thermal conductivity. Lub cev ntom ntom yog nyob nruab nrab ntawm 1.0-1.5, uas muaj kev lag luam dav dav. Lub teeb yuag high-alumina mullite cib kuj hu ua mullite cib. Lawv tau siv rau qhov kub thiab txias thiab tuaj yeem raug hluav taws xob ncaj qha, yog li cov nyhuv txuag hluav taws xob yog qhov tseem ceeb.
Mullite bricks yog dav siv nyob rau hauv cov cheeb tsam:
1. Ironmaking kev lag luam
Mullite refractory bricks yog siv nyob rau hauv lub overhangs thiab orifices ntawm cov cua kub ducts ntawm kub moj tej tawg qhov cub, yeeb nkab ntsug kav thiab ncaj cov kav dej nrog kub siab, nyob ib ncig ntawm cov cheeb tsam thiab qhov kub thiab txias qhov chaw. Cov qib ntawm mullite cib siv nyob rau hauv ntau qhov chaw sib txawv; qhov chaw ntawm torpedo tank tsheb uas cuam tshuam los ntawm molten hlau, slag kab cheeb tsam.
2. Kev lag luam iav ceramic
Mullite bricks yog siv nyob rau hauv lub ntsiab forehearth, regenerator thiab clarifier phab ntsa ntawm iav kilns; mullite bricks yog siv nyob rau hauv ceramic industrial kilns los ua saggers thiab kiln rooj tog.
3. Kev lag luam khoom siv hauv tsev
Mullite cib tuaj yeem siv rau hauv cov cement thiab txiv qaub rotary kiln linings.
