Cov kev coj ua zoo tshaj plaws hauvrefractory castableziab (ci / ci) tuaj yeem sau tau raws li: kev tswj hwm ntawm "dej" thiab "kub" thoob plaws tag nrho cov txheej txheem; kho installation, kho, thiab ziab raws li kev sib xyaw ua ke; thiab siv cov qauv ntsuas kub nce nkhaus, kho kom txaus, thiab tsim kom muaj qhov cua zoo kom tsis txhob tawg thiab thaum ntxov micro{0}} tawg, ua kom lub qhov cub ua kom lub neej ntev.
I. Integrated Approach: Installation-Kuring-Drying Integration
Cov tuam txhab thoob ntiaj teb xav txog "kev sib xyaw, molding, curing, thiab ziab" ntawm refractory castables raws li cov txheej txheem ua tiav, tsis yog tsom rau ntawm qhov nkhaus kom qhuav nws tus kheej.
Installation Stage Control: Qhov tseem ceeb yog muab tso rau ntawm kev ntxiv cov dej pom zoo thiab xyuas kom meej compaction kom tsis txhob muaj porosity siab thiab tsis tshua muaj zog vim dej ntau dhau / tsis txaus vibration, uas tuaj yeem tsim kev puas tsuaj rau kev ziab tom ntej.
Curing Theem Tseem Ceeb: Nws raug pom zoo kom kho ntawm 70–90℉ (kwv yees li 21–32 degree) tsawg kawg 24 teev (qee lub tshuab yuav tsum tau ntev dua). Txwv tsis pub, lub zog tsis txaus, tsis zoo permeability, thiab yuav ua rau muaj kev pheej hmoo ntau ntxiv.
II. Kev Tswj Xyuas Dej: Dej Dawb thiab Dej Txhaum Cai
Qhov kev pom zoo ntawm cov tuam txhab ua lag luam thiab cov kev kawm yog tias "dej dawb" thiab "cov dej sib xyaw ua ke" yuav tsum tau muab tshem tawm hauv cov theem thiab hauv kev tswj hwm, nrog rau kev nkag siab tag nrho ntawm lawv qhov kev tso tawm qhov kub thiab qhov ntim nthuav dav.
Dej Dawb (Lub Cev Dej): Vaporizes ib ncig ntawm 100 degree, nthuav mus txog kwv yees li 1600 zaug hauv ntim. Yog hais tias txoj kev khiav yog obstructed los yog kub nce sai heev, nws yuav yooj yim ua rau "steam explosion."
Tshuaj Dej: Cement hydrates decompose thiab tso dej nyob ib ncig ntawm 227 degree, 277 degree, thiab 549 degree. Cov tuam txhab ua lag luam yuav teeb tsa nyob hauv lossis qeeb- thaj chaw nce siab nyob ib puag ncig cov kub no kom tsis txhob hla dhau qhov "cov ntsiab lus txaus ntshai."
III. Kev Tswj Kub thiab Cov Cuab Yeej Cuab Yeej Cuab Yeej
Qhov kev coj ua zoo tshaj plaws yog txhawm rau txhim kho kev ziab kom qhuav raws li cov khoom siv thiab cov hauv ob sab phlu thickness, tab sis feem ntau ua raws li txoj cai ntawm "peb-theem tswj + tus nqi txwv + ntau lub platforms.
Peb -theem tswj:
Tsawg- qhov kub thiab txias (ambient kub - 100 degree): Cov cua kub tsis tshua muaj siab, ntev -lub sij hawm txuag hluav taws xob kom tso dej dawb.
Qhov Nruab Nrab Kub Kub (kwv yees li 100-350 degree): Qhov no yog thaj chaw kub hnyiab thiab thaj chaw hydrate decomposition tseem ceeb. Multi-theem rwb thaiv tsev thiab cov cua kub tsawg ntawm 10–30℃/ h yog siv los tiv thaiv cov cua ntxiab.
Qhov Kub Kub Kub (350℃rau lub hom phiaj kub): Cov cua kub tswj tau ntxiv, tshwj xeeb tshaj yog nrog kev ncua ntawm kwv yees li 500-550℃kom paub meej tias kev tshem tawm cov tshuaj efflorescence tiav, ua ntej thaum kawg cua sov kom ze rau qhov ntsuas kub rau qhov kawg ci.
Kev ntsuas cua sov yog txuas nrog cov tuab: Cov tuam txhab ua lag luam tau hais tias "cov ntaub ntawv tuab thiab cov ntaub ntawv sib xyaw yuav tsum raug ntsuas cais." Qhov ntau dua qhov tuab, qhov qis dua qhov pom zoo cua sov thiab qhov kub ntawm qhov sib txawv ntawm txhua theem. Cov seem rwb thaiv tsev ntxiv yuav tsim nyog.
IV. Kev nyab xeeb thiab kev cia siab: Kev tso pa tawm, qhov cua, thiab saib xyuas
Cov tuam txhab kev pabcuam engineering thiab cov tuam txhab tsim khoom tau hais ntau zaus hauv lawv cov ntawv hais tias kev ziab tsis ua haujlwm feem ntau tsis yog vim muaj teeb meem nrog tus qauv nkhaus, tab sis ua rau tsis txaus ntawm - qhov chaw tso pa tawm, qhov cua, thiab kev saib xyuas.
Exhaust thiab Ventilation:
Muaj cov pa tso pa tawm, qhov chaw ntawm lub qhov cub tawg, lossis cov pa hluav taws xob tshwj xeeb yog qhov tseem ceeb los tswj cov huab cua zoo thaum ziab. Txwv tsis pub, cov av noo nyob rau hauv lub cub tawg yuav sai sai mus txog 100%, ua rau nws nyuaj rau ya raws kom dim ntawm tus nqi tsim.
Avoid applying dense coatings or prematurely sealing the surface of the lining to prevent blockage of the moisture channels in the "first stage."
Kev ntsuas kub thiab kev tsim qauv:
Ua ntsuas kub ntawm qhov chaw tseem ceeb (qhov kub ntawm qhov chaw, qhov chaw txias, thiab qhov nruab nrab ntawm cov ntaub tuab tuab) thiab sib piv qhov sib txawv ntawm qhov kub thiab txias nrog cov cua sov. Yog hais tias qhov kub thiab txias hauv cheeb tsam nce nrawm dua los yog noo noo yog qhov txawv txav, lub combustion load yuav tsum tau kho tam sim ntawd.
V. Khoom siv thiab txheej txheem optimization: Txhim kho Dryability
cov tuam txhab refractory thiab cov chaw tshawb fawb tseem tab tom txhim kho "dryability" ntawm refractory castables los ntawm kev tsim thiab txheej txheem txheej txheem, yog li tsim nyog ua kom lub voj voog kom qhuav thaum ua kom muaj kev nyab xeeb.
Kev siv cov tshuaj ziab khaub ncaws: Nws raug nquahu kom siv cov tshuaj ziab khaub ncaws xws li cov organic fibers thiab hmoov hlau. Tom qab hlawv tawm ntawm qhov kub qis, cov no tsim cov kab zoo, txhim kho huab cua permeability thiab tsis kam tawg.
Optimized Formulation thiab Txheej Txheem:
Tsawg-cement/ultra-qis- cement systems, gradation tsim nyog, thiab kev tswj dej nruj kom txo tau cov dej noo ntau dhau, txhim kho chav tsev- qhov kub thiab txias thiab permeability, thiab pab txhawb kev tawm ntawm cov dej noo hauv nruab nrab- qhov kub thiab txias.
Rau cov tuab-pab, ntau- txheej txheej, qee lub tuam txhab tsim cov porosity siab dua los yog ib txheej permeable nyob rau hauv cov txheej txheem rov qab, ua ke nrog cov quaj qhov hauv lub plhaub, kom txo qis hauv siab.
