Tshawb nrhiav vim li casfused silica bricksyog nyiam rau coke cub kub kho. Kawm paub yuav ua li cas lawv nyob ze - xoom thermal expansion thiab thermal shock kuj zoo heev txhim kho lub cub tawg kev pab cuam lub neej thiab kho efficiency.
1. Tom qab: Qhov Kev Sib Tw ntawm Coke Cub Kub Kho
Hauv kev lag luam steelmaking, coke ncu ua haujlwm tsis tu ncua ntawm qhov kub siab tshaj 1300 degree. Nyob rau tib lub sijhawm, kev kub ntxhov siab thiab tshuaj lom neeg ua rau lub qhov cub refractory tawg, tawg, lossis deform.
Txhawm rau kom muaj txiaj ntsig zoo, cov txheej txheem kho kub - qhov chaw kho cov haujlwm ua tiav yam tsis tau ua kom txias rau qhov cub- tau dhau los ua qhov tseem ceeb.
Txawm li cas los xij, xaiv cov khoom siv refractory zoo rau qhov siab -kub kho kub tseem yog ib qho kev sib tw tseem ceeb. Cov tsoos silica bricks zoo li nthuav thiab tawg thaum lub sij hawm kub installation, ua rau ua tsis tiav ntxov ntxov.
2. Dab tsi yog Fused Silica Cib?
fused silica cib yog tsim los ntawm siab -purity quartz xuab zeb (SiO₂ Ntau dua lossis sib npaug li 99.8%) melted nyob rau hauv hluav taws xob arc rauv thiab txias nyob rau hauv kev tswj xyuas los tsim ib qho amorphous, glassy qauv.
Tsis zoo li cov silica cib zoo tib yam, uas muaj cov qauv crystalline thiab cov thermal expansion coefficient tseem ceeb, fused silica cib nthuav tawm ze rau - xoom thermal expansion thiab exceptional thermal shock resistance.
Cov khoom no ua rau nws zoo tagnrho rau ib puag ncig uas muaj kev rov ua cua sov thiab cua txias dua -xws li lub qhov cub coke, iav rauv, thiab phab ntsa regenerator.
3. Vim li cas Fused Silica Bricks ua tau zoo tshaj plaws hauv Coke Cub Kub Kho
3.1 Nyob ze -Xoom Thermal Expansion
Thaum lub sij hawm kho kub, cov phab ntsa rauv yog twb nyob ntawm 800-1000 degree.
Ordinary silica bricks nthuav dav sai thaum kev teeb tsa, tsim kev ntxhov siab sab hauv uas ua rau tawg.
Los ntawm qhov sib txawv, fused silica cib tuav qhov kev ruaj ntseg thoob plaws hauv cov cua sov thiab cua txias, kom ntseeg tau tias kev sib txuam seamless nrog cov ntaub ntawv uas twb muaj lawm.
3.2 Qhov zoo tshaj plaws Thermal Shock Resistance
Coke ncu muaj qhov kub thiab txias heev thaum cov roj ntws los yog cov khoom thauj khoom hloov pauv.
Fused silica tus qauv amorphous tiv thaiv microcracking thaum lub sij hawm hloov kub ceev, txo cib spalling thiab ncua kev pab cuam lub neej.
3.3 Muaj zog tshuaj lom neeg ruaj khov
xoom expansion silica bricks tiv thaiv corrosion los ntawm alkali vapors, carbon deposits, thiab acidic gases generated thaum lub sij hawm tsim coke.
Lawv cov uas tsis yog -reactive nto txo qhov paug thiab ua kom muaj kev ua haujlwm huv hauv qhov cub.
3.4 Lub neej ua haujlwm ntev dua thiab cov nqi siv tau
Vim hais tias fused silica bricks tswj kev ncaj ncees txawm tias nyob rau hauv thermal stress, lawv lifespan yuav 1.5-2 zaug ntev dua li cov tsoos silica bricks.
Qhov no txhais tau tias kev kho tsawg dua, lub sijhawm luv luv, thiab cov nqi kho mob qis dua -ib qho txiaj ntsig ncaj qha rau cov nroj tsuag steel loj.
4. Daim ntawv thov hauv Coke Cub Kub Kho
Fused silica bricks yog tam sim no dav siv rau kev kho kub thiab hauv ob sab phlu reconstruction nyob rau hauv: Regenerator phab ntsa thiab combustion chambers, Coke cub ru tsev thiab sidewalls, Flue channels thiab burner zones, hloov chaw raug kub cycling.
Lawv compatibility nrog silica-raws li mortars thiab castables ua kom muaj kev sib raug zoo, ua rau lawv zoo tagnrho rau kev ceev ntawm - qhov chaw teeb tsa thaum lub sijhawm ua haujlwm kub.
Ntiaj teb no Kev Lag Luam Kev Lag Luam: Kev xav tau nce rau Fused Silica
Nrog cov kev cai ib puag ncig nruj dua thiab lub zog- cov qauv kev ua tau zoo hauv cov hlau thiab iav kev lag luam, kev thov thoob ntiaj teb rau siab -kev ua tau zoo fused silica cib tau nce siab heev.
Cov neeg yuav khoom tam sim no ua qhov tseem ceeb:
Lub sijhawm ua haujlwm ntev dua
Txo downtime
Recyclable thiab tsawg- cov ntaub ntawv carbon refractory
Cov neeg tsim khoom xws li Topower Refractory tau teb los ntawm kev muab cov khoom siv xoom nthuav dav silica cib tsim rau cov qauv coke cub tshwj xeeb, suav nrog ua ntej - zoo li arches, sab blocks, thiab ru tsev panels.
Fused silica cib tau ua pov thawj tias yog cov kev daws teeb meem zoo tshaj plaws rau coke qhov cub kub kho ua tsaug rau lawv qhov sib xyaw ua ke ntawm xoom thermal expansion, zoo heev thermal shock resistance, thiab kev pab lub neej ntev.
Rau cov nroj tsuag steel nrhiav kev tsim khoom ruaj khov thiab txo cov nqi kho mob, hloov mus rau fused silica refractory cov ntaub ntawv muab kev ntsuas kev ua tau zoo thiab cov txiaj ntsig kev lag luam.
