Dab tsi ntawm refractory bricks yog qhov zoo tshaj plaws rau hauv ob sab phlu cement rotary kiln decomposition rauv thiab tertiary cua duct?
1. Nyob ntawm qhov loj ntawm lub qhov cub
Covrefractory brickssiv rau hauv cov cement teb kiln decomposition rauv thiab tertiary cua duct muaj feem xyuam rau qhov luaj li cas ntawm lub cub tawg. Qee tus siv cov pob zeb alumina siab lossis silica mullite cib, thiab qee qhov siv cov cib uas muaj zog alkali-resistant.
2. Hom refractory cib yuav tsum siv rau ob qhov chaw?
Yog li cas lub cib yuav tsum siv rau ob ntu no? Lub neej kev pabcuam siv yog molysil silica cib, thiab 1550 silica molybdenum cib siv nyob rau hauv lub qhov cub decomposition yuav kav ntev tshaj peb xyoos.
Tau kawg, kuj tseem muaj cov neeg tsim khoom sivsiab alumina cibthiab anti-flaking alumina bricks. Txhawm rau siv alumina bricks, refractory cib nrog cov ntsiab lus txhuas ntawm ntau tshaj 70% yuav tsum tau siv. Txawm li cas los xij, spalling feem ntau tshwm sim thaum siv hauv ob qhov chaw. Lub sijhawm siv feem ntau yog li ib xyoos. Yog hais tias anti-flaking high-alumina bricks yog siv, lub sij hawm siv yuav kuj ntev, tab sis tus nqi ntawm ob lub cib yuav txawv heev. Vim hais tias cov zirconium tivthaiv ntxiv rau cov anti-flaking siab alumina hluav taws cib, tus nqi ntawm zirconium yog siab heev, uas zoo li nce tus nqi ntawm anti-flaking siab aluminium bricks.
3. High-strength alkali-resistant bricks yuav siv tau
Kuj tseem muaj zog alkali-resistant refractory bricks. Lub tertiary cua duct tseem tuaj yeem siv cov cib uas muaj zog alkali-resistant, vim hais tias cov alkali tsis kam ntawm alkali-resistant bricks yog haum rau qhov no. Txawm li cas los xij, nws yog qhov tsim nyog los siv cov tshuaj tiv thaiv siab alumina cib lossis 1550silica mullite cibrau lub qhov cub decomposition vim nws lub neej ua haujlwm ntev.
Yog tias muaj zog alkali-resistant bricks thiab high-aluminium cib siv nyob rau hauv ob qhov chaw, kev pab cuam lub neej ntawm high-strength alkali-resistant bricks yuav ntev dua li ntawm high-aluminium cib. Yog vim li cas yog vim li cas alkali tsis kam ntawm high-strength alkali-resistant bricks yuav tsis ua rau hauv ob sab phlu cib tev tawm. , thiab kev siv lub siab alumina firebricks feem ntau tev tawm hauv qab alkali yaig. Yog li ntawd, lub sijhawm siv luv luv, ua rau muaj kev hloov pauv ntau zaus, uas ua rau cov nqi siv ntau ntxiv.
4. Nws yog feem ntau siv 1550 silica mullite cib
Tam sim no, 1550 silica molybdenum cib feem ntau yog siv nyob rau hauv tertiary cua ducts thiab decomposition furnaces ntawm cement rotary kilns. Ib qho kev faib ua feem ntawm silicon carbide yog ntxiv rau silica molybdenum cib, uas muaj zog hnav tsis kam thiab corrosion kuj thiab siv tau rau ntau tshaj peb xyoos. Tsis txhob muaj teeb meem tsis tsim nyog ntawm lub sijhawm thiab tus nqi uas tshwm sim los ntawm kev hloov cov ntaub ntawv ntau zaus.
5. Nws yog qhov zoo dua los siv Silica Mullite Cib
High alumina bricks tsis tuaj yeem xaiv vim yog tus nqi sib txawv ntawm silicon molybdenum cib thiab siab alumina firebricks. Kev hloov pauv ntawm siab aluminium bricks yuav ua rau cov nqi ntau lawm. Yog li ntawd, muab piv rau kev siv cov refractory cib no, nws yog qhov zoo dua los siv silica molybdenum cib rau decomposition furnaces thiab tertiary cua ducts.
