Thaum lub sij hawm ua haujlwm ntau lawm, coke cub qhov rooj yuav tsum tau qhib thiab kaw ntau, nrog qhov chaw siab kub thiab nrawm hauv Coke qhov hluav taws xob kub. Cov kab kev tsoos yog ua nrog Cordierite cib lossisAv nplaum cib, nrog luv voj voog thiab nquag saib xyuas. Lub hauv paus ua rau yog:
1. Cov khoom siv coking yog qhov nyuaj, acidic gases nkag mus rau cov ntxaij vab tshaus rau cov ntxaij vab tshaus, txuas ntxiv mus rau qhov ntxaij vab tshaus, thiab cov kev ua kom nrawm nrawm nrawm nrawm;
2. Cov cua sov ceev ceev thiab cua txias ua rau thaj chaw saum npoo av thiab ua rau ces kaum tev;
3. Tar cov pa roj carbon tau zoo heev, thiab kev quab yuam ua haujlwm txuas ntxiv ua kom puas hauv cov cib lub sijhawm tshem tawm.
Qhov zoo tagnrhoRefractory CastableRau cov luag haujlwm no yuav tsum yog li muab plaub tus ncej puab: Thermal} paab tso pa tawm thiab yooj yim} kub}- lub vev xaib nruab.
Thermal -} Poob siab ua tau zoo
A magnesia-alumina spinel matrix withstands >50 qhov kev cog lus nrawm nrawm yam tsis muaj kev tawg vim tias cov roj hmab muaj roj thermal los ntawm micro {1} back tawg thiab rov ua kom zoo. Cov kev ntsuam xyuas ywj siab ntawm qhov rooj rov qab nrog cov ntaub ntawv refractable no tsis muaj kev sib tw tom qab 18 lub hlis, whereas} alumina sib xyaw yuav tsum muaj kab rau lub hlis.
Ntim ruaj ruaj thiab nkag dag
Lub spinel theem locks lub microstructure saum 1 500 degree, tiv thaiv cov 1-2% kev nthuav dav uas ua rau lub qhov rooj sib yuav thiab roj to. Qhov kev ruaj khov no tau txhawb ntxiv los ntawm 5-8% feded - porosity conductivity thiab txiav cov cua sov poob los ntawm 12% piv nrog cov khoom siv tuab tuab.
Kuj rau cov pa roj carbon tsim - Up
Ceke -}}}}} pa kua kub yog nplua nuj hauv co thiab tar vapors uas tso cov pa roj carbon rau ntawm cov ntsej muag kub refactory. Qhov tsawg fe₂o₃ cov ntsiab lus (<0.5 %) in the spinel castable prevents catalytic carbon growth, allowing doors to be cleaned by simple air-lancing rather than mechanical chipping .
Txhim kho thiab kho cov txiaj ntsig zoo
Vim tias cov khoom siv tau ua ke ntawm chav tsev kub thiab tau txais lub zog tag nrho tom qab 24 teev ua tiav kev sib tw tuaj yeem nqa tawm thaum lub sijhawm 36-teev tawm. Cov tswj hwm cog cov tswj hwm tias downtime yog txiav los ntawm 40% piv nrog cib relines.
Nyob rau hauv xyoo tsis ntev los no, loj- ntim coke cooke ncu tau hloov mus rau "Fused Refracticting Prefabricated blocks, thermal poob siab thiab yaig ntawm ib qho stroke:
1. Matrix: av nplaum raw khoom yog pheej yig, siab hauv lub zog, thiab muaj cov txheej txheem molding;
2. Kev ua haujlwm theem: Fused Quartz muaj qhov tsawg kawg tsis muaj hluav taws xob nthuav tawm coeffanic (≈0.5 × 10⁻⁶ / degree). Tom qab kev taw qhia, nws tuaj yeem: txo cov thermal expansion ntawm cov kab ke thiab txo qhov kub nyhiab kev ntxhov siab; Induce microcrack kev ua kom nruj thiab txhim kho cov cua sov poob siab; Nws yog cov kua qaub - tiv taus thiab carbon-}}} {tiv taus, tiv thaiv cov targetation; Qhov ceev ntom thiab thermal conductivity yog ob qho tib si qis, thiab qhov rooj hluav taws xob yog lub teeb thiab muaj cov rwb thaiv tsev zoo heev.
Av nplaum + Fused Quartz Composite Breakricated Blocks ua rau muaj kev lag luam coke thiab kev ua haujlwm siab thiab kaw, muaj zog erosion, thiab lub teeb hnyav ". Nws yog qhov kev daws teeb meem zoo tshaj plaws rau cov kab ntawm loj- ntim coke qhov rooj hauv qhov rooj tam sim no thiab yav tom ntej.
