Teb chaws cub ua ke hauv ob sab phlu yuav raug nplawm los ntawm cov khoom kub hauv cov plua plav thiab ua rau cov plua plav, thiab tseem xav tau kev coj ua kom sov. Los ntawm ntau lub xyoo tshawb nrhiav nrog kev nce siab zoo, peb lub tuam txhab tau tsim ua kom tiav zoo-zog ua ntej ua ntej cib. Nws muaj hi-zog hnav txheej ntawm zoo corrosion zoo, thiab lub teeb-phaus txheej txheem txuag hluav taws xob kom muaj kev txuag hluav taws kub hauv cov kiln. Tsis tas li ntawd, peb muaj cov qauv tsim tshwj xeeb hauv cov duab cib thiab Masonry hom, lees paub kev ua tau zoo ntawm lub sab hauv. Los ntawm daim ntawv thov nyob rau hauv ntau pelletizing nroj tsuag, ntau yam kev sib tw ci coke, uas tuaj yeem txhim kho tus nqi kev lag luam, kom txuag tau tus nqi thiab muaj kev lees paub thiab qhuas cov neeg siv.
Cov txheej txheem ua haujlwm ntawm cov qoob loo ua ntej rau cov fuster mullite, homogenized bauxite clinker, thiab cov khoom siv zoo siliab carbide thiab cov khoom sib ntxiv. Nws cov thermal conductivity yog qis dua li ntawd ntawm cov khoom lag luam zoo sib xws, muaj lub zog hluav taws xob, siab ruaj khov rau alkali erosion.
Lub thermal rwb thaiv tsev txheej ntawm cov cib kaub ua ntej rau cov khoom siv roj av zoo nkauj thiab cov khoom siv sib txuas, thiab yog tsim los ntawm cov huab cua tshwj xeeb cov txheej txheem Sinteringing. Nws muaj cov yam ntxwv ntawm kev ua haujlwm siab nrog cov txheej txheem ua haujlwm, muaj zog compressive compressive, thiab tsawg thermal conductivity.
Cov khoom lag luam
Lub thermal rwb thaiv tsev txheej ntawm cov cib kaub ua ntej rau cov khoom siv hluav taws xob qeeb, thiab corundic thermal cov ntaub ntawv, nrog qhov qis qis thiab zoo thermal rwb thaiv tsev cov txiaj ntsig.
Cov kab ntawm lub cubtary tsis yog tsuas yog ua rau cov yaig ntawm cov khoom kub hauv cov av roj kub thiab cov yaig ntawm cov plua plav roj, tab sis kuj yuav tsum muaj cov pa thermal zoo. Tom qab xyoo ntawm cov kev tshawb fawb tau zoo thiab kev txhim kho, peb lub tuam txhab tau tsim cov cib ua kom prefabricated ua ntej rau lub cub qeeb. Cov ris tsho-resistant txheej muaj lub zog siab thiab cov khoom yaig zoo heev, thiab ua kom cov kev txhim kho thermal no, uas ua kom cov kev txhim kho ntawm kev ua hluav taws xob ua kom zoo hauv cov KILN. Ib qho ntxiv, peb qhov kev tshwj xeeb tsim hauv cib hom thiab Masonry txoj kev lees paub qhov kev ua tau zoo tag nrho ntawm tag nrho ob lub ntsej muag. Tom qab tau siv nyob rau hauv cov nroj tsuag pellet, cov roj av coke, pelled roj coke, nws tau ua tiav cov txiaj ntsig zoo thiab muaj kev pabcuam lub neej ntau dua 2 xyoos. Nws tau txhim kho cov kev pab nyiaj txiag rau cov neeg siv thiab cov nqi tswj xyuas tau zoo, thiab tau raug lees paub thiab qhuas los ntawm cov neeg siv.
Thaum pib ntawm lub xyoo pua no, cov roj cotary tau ua nrog ib-txheej high-alumina lossis alkaline cib. Vim yog lawv lub siab thermal conductivity, lub kiln plhaub kub tau siab (txog 300 degree), uas ua rau muaj kev kub ntxhov loj thiab muaj zog siv hluav taws xob. Txawm hais tias ob-txheej los yog ntau-txheej masonry xws li rwb thaiv tsev txheej thiab xoob, ua rau muaj kev ntseeg siab, thiab lub cib poob lossis pob zeb. Kev siv ntawm kev sib xyaw ua kom precast bricks rau cov ceeb nti ceeb tuaj yeem daws cov teeb meem no. Cov txheej hnyav thiab txheej txheem ib nrab yog ua ke rau hauv ib qho, uas tsis yog txo qis lub ntsej muag kub, tab sis kuj ua kom muaj kev ncaj ncees ntawm lub cev hauv lub caij sib hloov thaum lub sijhawm sib hloov thaum lub sijhawm sib hloov. Nyob rau tib lub sijhawm, nws kuj tuaj yeem txo qhov hnyav ntawm cov kab, uas tau txais txiaj ntsig rau kev ua haujlwm ntawm lub teb chaws cub.
Tus yuam sij rau kev txhim kho ntawm kev sib xyaw ua kom precast cricks cov khoom ruaj khov nyob rau hauv qhov sib koom tes ntawm cov txheej hnyav thiab txheej txheem ib nrab thiab lub teeb txheej txheem. Tom qab sim, nws tau paub tias qhov hnyav thiab lub teeb ci sib xyaw yuav tsum ua kom tau raws li ob qho xwm txheej hauv qab no:
(1) Cov ntaub ntawv ntawm cov khoom hnyav thiab nruab nrab teeb tsa siv rau cov kev sib tw yuav tsum zoo sib xws. Nws yog qhov nyuaj kom tau txais cov khoom zoo sib xyaw zoo thaum ob yam khoom sib txawv nrog sib txawv.
(2) Qhov sib txawv hauv cov khoom ntom ntom ntawm hnyav thiab cov khoom siv teeb tsis tuaj yeem loj heev. Yog tias lub ntim ceev sib txawv yog qhov loj, cov kab nrib pleb yuav tshwm sim ntawm kev sib koom ua ke vim tsis sib haum hluav taws xob shrinkage. Tom qab ntau qhov kev ntsuam xyuas, qhov ntim ntom ntawm lub teeb lub teeb ua ke nrog mullite alkali-resistant cib yog txog 1.8g / cm {6}}.
1: Tsim los ntawm kev sib xyaw ua ke cib rau cov cuv
LOJ COLNING CLOCKS feem ntau ua nrog rab riam-ntug cib Lub teeb txheej txheej ntawm cov cib ntau yog feem ntau 80mm tuab thiab sib xyaw ua ke nrog cov txheej hnyav txheej.
2: Khoom lag luam
Cov ntaub ntawv hnyav thiab cov khoom siv teeb pom kev sib xyaw ua ke thiab nqus tau nyias, ntsuas sib cais, thiab cov partitions ntxiv thiab muab cov ntaub ntawv ntxiv. Tom qab molding siv cov xovxwm 630T, lawv tau qhuav thiab raug rho tawm haujlwm ntawm 1410 degree rau 8H. Cov khoom tau pom hauv daim duab 4. Kev ua haujlwm ntsuas ntawm ib nrab txheej ntawm cov cib muaj npe nyob hauv qab rooj hauv qab no.
