Peb yuav tsum xyuam xim rau dab tsi thaum ziab khaub ncaws rwb thaiv tsev castables?
Refractory castable yog ib qho tseem ceeb ntawm cov khoom siv hauv tsev, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas yuav tsum tau ua kom sov thiab hnav tsis kam, xws li hauv ob sab phlu hauv qhov chaw kub. Cov chaw no xav tau tshwj xeeb siab flexural zog thiab tensile lub zog, thiab castables tuaj yeem ua tau raws li cov kev cai no.
Kev ua tau zoo ntawm castables yeej muaj ntau yam ua nrog nws cov ntaub ntawv raw. Cov txheej txheem kev npaj cov khoom sib txawv yuav ua rau cov khoom sib txawv ntawm castables. Ntawm lawv, lub teeb yuag thermal rwb thaiv tsev castables yog dav siv nyob rau hauv ntau lub tsev vim lawv lub teeb yuag thiab thermal rwb thaiv tsev zog.
Txawm li cas los xij, tsis txhob xav tias txhua yam yuav zoo tom qab kev tsim kho castable tiav. Muaj ib kauj ruam tseem ceeb heev uas feem ntau tsis saib xyuas thiab qhov ntawd yog ziab. Yog tias ziab tsis tau ua tiav raws sijhawm tom qab kev tsim kho tiav, cov teeb meem hauv zos yuav tshwm sim, uas yuav cuam tshuam rau kev ua haujlwm tag nrho. Nws zoo li thaum peb ci ncuav mog qab zib, yog tias peb tsis nco qab nqa tawm mus ci, lub ncuav mog qab zib yuav dhau los ua tawv.
Yog li dab tsi koj yuav tsum xyuam xim rau thaum ziab khaub ncaws rwb thaiv tsev refractory castables?
1. Cov txheej txheem ziab ntawm lub teeb yuag rwb thaiv tsev castables yeej yog ib txoj hauj lwm technical. Kev ua haujlwm tsis raug tuaj yeem ua rau muaj teeb meem!
Vim tias cov castable tsuas yog tso siab rau cov cement solidification los txhim kho nws lub zog, thiab thaum lub sij hawm ziab, cov dej noo yuav hloov ntawm cov kua mus rau roj, ua rau lub siab nce.
Yog hais tias qhov kub nce siab heev thiab cov roj tsis tuaj yeem tawm, lub zog quab yuam yuav raug tsim nyob rau hauv lub castable. Lub zog quab yuam no muaj zog heev uas yuav ua rau lub castable tawg! Ib yam li thaum peb boil dej, yog tias cua sov siab dhau lawm, lub lauj kaub lub hau yuav tuaj yeem tshwm sim vim yog qhov cub.
Yog li ntawd, thaum ziab cov rwb thaiv tsev castables, lub tshav kub yuav tsum tau tswj kom zoo, qhov kub thiab txias yuav tsum tsis txhob nce ceev heev, thiab cov roj yuav tsum tau muab sij hawm kom maj mam tso tawm. Txoj kev no, peb xyuas kom meej tias cov castables qhuav sib npaug thiab nyab xeeb, kom txhua daim mus txog qhov ua tau zoo!
2. Nyob rau hauv cov txheej txheem ziab, qhov txheeb ze av ntawm huab cua plays lub luag haujlwm tseem ceeb.
Tus txheeb ze humidity tuaj yeem cuam tshuam ncaj qha rau qhov kub thiab txias ceev ntawm cov ntaub ntawv refractory!
Xav txog tias thaum huab cua noo siab, qhov kub thiab txias tseem ceeb heev. Vim tias qhov kub siab dua, qhov me dua qhov txheeb ze av noo yuav yog, yog li qhov ziab ceev ntawm cov ntaub ntawv refractory yuav sai dua. Yog li ntawd, yog tias koj xav kom qhuav cov ntaub ntawv refractory sai, nws yog ib lub tswv yim zoo kom nce qhov kub kom tsim nyog.
Tsis tas li ntawd, cov av noo ntawm qhov ziab kom qhuav kuj yog qhov tseem ceeb rau kev saib xyuas thaum lub sijhawm tsim khoom. Cov av noo sib txawv yuav cuam tshuam rau kev ziab ntawm cov ntaub ntawv, yog li kev tswj cov av noo kuj yog qhov txuas tseem ceeb los xyuas kom cov khoom zoo.
Txhawm rau ua kom tiav, yog tias koj xav tau cov ntaub ntawv refractory kom qhuav sai, tswj qhov kub thiab av noo yog qhov tseem ceeb!
3. Nyob rau hauv lub ntiaj teb no ntawm kev hais txog av noo, muaj ob lub ntsiab lus tseem ceeb: tsis muaj av noo thiab txheeb ze humidity.
Tsis muaj av noo, yooj yim muab, yog qhov hnyav ntawm cov dej vapor muaj ib lub cubic meter ntawm huab cua. txheeb ze humidity hais txog qhov piv ntawm cov av noo ntawm huab cua mus rau lub saturated humidity ntawm cov av noo nyob rau tib lub kub.
Ob qhov ntsuas ntsuas av noo no yeej muaj feem cuam tshuam thiab yog qhov tseem ceeb rau kev ziab ntawm cov castables hnyav. Vim tias cov av noo tsis tuaj yeem tswj tau zoo, cov castable yuav qhuav tsis sib npaug lossis tawg.
Yog li ntawd, thaum cuam tshuam nrog cov teeb meem ziab ntawm lub teeb yuag rwb thaiv tsev castables, peb yuav tsum tsis tsuas yog them sai sai rau qhov kub thiab txias, tab sis kuj tseem ua tib zoo saib xyuas cov av noo. Tsuas yog los ntawm kev tuav qhov sib npaug ntawm cov av noo thiab qhov kub thiab txias tuaj yeem ua kom ntseeg tau tias cov castables tuaj yeem qhuav sib npaug thiab nyab xeeb kom ua tiav qhov kev ua tau zoo tshaj plaws.
Hauv luv luv, ntau yam yuav tsum tau them sai sai rau thaum ziab khaub ncaws insulating castables. Txoj kev ziab kom raug tuaj yeem ua kom muaj kev ua tau zoo thiab siv cov nyhuv ntawm cov castables thiab txhim kho nws cov kav ntev thiab ruaj khov. Yog li ntawd, txhua yam ntawm cov txheej txheem kev tsim kho yuav tsum nruj me ntsis tswj thiab kev tswj hwm yuav tsum tau ua raws li kev tsim kho kom zoo thiab kev nyab xeeb.
