Nyob rau hauv cov hlau thiab metallgical kev lag luam, Coke ncu yog cov khoom muaj zog tseem ceeb {}}, thiab kev mob tshuaj lom neeg uas ua rau yaj, puas, thiab kev laus. Ua kom muaj kev ua tau zoo ntev thiab kev ua tau zoo ntawm Cokeuens yuav tsum tsis tsuas yog kev tswj hwm kev ua haujlwm tab sis kuj siv cov khoom siv hluav taws xob ntau. Ib qho ntawm cov kev daws teeb meem zoo tshaj plaws yog tusSilica Cib, uas tau ua pov thawj los ua ib qho kev ntseeg siab thiab tus nqi {- Cov khoom siv coke txuas ntxiv.
Coke Cub Kev Ua Phem feem ntau tshwm sim los ntawm kev sib xyaw ntawm cov xwm txheej:
1. Thermal kev ntxhov siab thiab caij tsheb kauj vab
Coke ncu Ua haujlwm ntawm huab cua sov heev, feem ntau tshaj li 1,200 degree. Rov ua cua sov thiab cua txias ua rau cov khoom siv hluav taws xob ua kom nthuav dav thiab cog lus. Sij hawm dhau mus, cycling no tuaj yeem ua rau tawg thiab npuaj ntawm cov cib cib.
2. Kev siv tshuab ua haujlwm thiab thauj khoom siab
Kev txav mus los ntawm coke thiab cov neeg kho tshuab siab nyob rau hauv lub sam thiaj li lub siab siv ntau txoj kev ntxhov siab. Crick tshem tawm lossis misalignment feem ntau ua raws, ceev nrawm txheej ua tsis muaj zog.
3. Tshuaj lom neeg tawm tsam los ntawm alkalis thiab cov sib txuas tsis sib xws
Thaum coking, cov roj av tsis muaj roj thiab cov duab sib dhos alkali raug tso tawm, uas tuaj yeem hnov mob nrog cov refractory ob sab. Cov tshuaj lom neeg sib cuam tshuam tab sis txo lawv cov load - bearing muaj peev xwm.
4. Cov khoom siv tsis zoo lossis kev teeb tsa
SubopTimal cov ntaub ntawv refractory lossis cov txuj ci teeb tsa tsis muaj zog tuaj yeem ua kom luv luv lub sijhawm cub. Siv cov khoom uas tsis tuaj yeem tiv thaiv qhov cub ua haujlwm yuav ua rau tsis ua tiav thaum ntxov.
Lub luag hauj lwm ntawm Silica Cib hauv Mitigating Cub puas
Silica regractory cib fim feem ntau ntawm silicon dioxide (sitio₂), muaj qhov kev daws teeb meem tshwj xeeb rau kev cuam tshuam rau coke qhov cub degradation. Ntawm no yog li cas:
1. Super superi Thermal ruaj khov
Ib qho ntawm cov khoom seem ntawm Silica Hluav Taws Kub yog lawv qhov kev tiv thaiv zoo heev rau cov kub. Lawv tuaj yeem tiv thaiv cov haujlwm txog 1,650℃yam tsis softening lossis yaj, ua rau lawv zoo tagnrho rau Coke cub thiab ru tsev qauv. Lawv tus nqi nthuav tawm tsawg kuj txhais tau hais tias lawv tiv thaiv kev tawg thaum lub caij tsheb kauj vab thermal, txo qis hauv kev kho kom zoo.
2. Lub siab tiv taus rau tshuaj corrosion
Silicon -} Cov ntaub ntawv refractory, suav nrog cov hluav taws kub tsis kam tawm tsam los ntawm alkalis thiab acidic vapors tsim thaum lub sijhawm ua haujlwm. Lawv tej microstructure tiv thaiv kev sib sib zog nqus cov neeg sawv cev, yog li tswj cov qauv txheej txheem kev ntseeg sijhawm sijhawm.
3. Txhim Kho Cov Neeg Kho Tshuab Zog
Zoo Silica Clocks muab kev ua kom zoo nkauj compressive muaj zog, tso cai rau lawv dais hnyav cov neeg kho tshuab hluav taws xob hauv qhov cub. Thaum muab ntsia kom zoo, cov cib no tseem nyob twj ywm cov duab txawm tias tom qab xyoo ntawm kev ua haujlwm txuas ntxiv.
4. Tus nqi ua hauj lwm zoo thiab ntev - lub sij hawm
Txawm hais tias kev nqis peev thaum pib hauv high - {}}}}}}}}}}}}}}} dua kev ua kom lub neej tiv thaiv kom tus nqi. Silica Hluav Taws Xob Cov Hluav Taws Xob tseem muaj dav muaj dav, ua rau lawv xaiv rau qhov loj- teev cov ntawv thov.
Txhawm rau kom ua tau zoo ntawm cov txiaj ntsig ntawm silica - Raws refractories hauv coke ovens, qee txoj kev coj ua kom pom zoo:
Xaiv cov cib nrog ntau dua lossis sib npaug ntawm 95% Sio₂ cov ntsiab lus ** rau kev ua siab zoo-}} kev ua haujlwm kub.
Ua kom ntseeg tau txoj kev kho tau zoo thiab ziab ua ntej pib cua sov kom tiv thaiv noo noo {}}}}}}}}}}}} related crack cracking.
Ua haujlwm nrog cov kev paub nruab nrog kom tau lees paub qhov tseeb sib koom ua ke thiab sib ncag.
Nquag tshuaj xyuas thiab tswj cov chaw cub kom pom cov cim ntxov ntawm kev hnav.
Hauv kev xaus, kev laus thiab kev puas tsuaj ntawm Coke ncu yog qhov tsis taus tab sis tswj cov txheej txheem. Kev siv ntawm siab - Cov khoom ua haujlwm zoo xws li Silica Cib ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm cov siab no- cov chav kub. Lawv cov thermal zoo heev, tshuaj xyuas durability, thiab lub zog kho zog ua rau lawv lub pobzeb ntawm cov niaj hnub COKE Cub Tsim.
Txawm hais tias koj tau txhim kho lub chaw tsim kho tshiab lossis npaj cov khoom lag luam silicon refractory, ua rau muaj txiaj ntsig ntev, thiab txo cov nqi ntev.
Yog tias koj tab tom nrhiav kev sib tham lossis siab - zoo silica - raws refractory cib, tiv tauj peb
