1. Ua ntej kev tsim kho cov castables refractory, yuav tsum tau soj ntsuam cov nram qab no nruj me ntsis: (1) xyuas cov tsos thiab huv si ntawm cov khoom yuav tsum tau poured; (2) Tshawb xyuas cov khoom siv thiab cov cuab yeej siv, thiab cov khoom seem xws li cov cuab yeej vibrating yuav tsum tsis muaj zog; (3) Txheeb xyuas hom, qhov loj me, kev teeb tsa thiab vuam zoo ntawm cov thauj tog rau nkoj, thiab cov hlau thauj tog rau nkoj yuav tsum tau kho nrog kev them nyiaj nthuav dav; (4) Txheeb xyuas qhov chaw nyob ib puag ncig refractory cib hauv ob sab phlu thiab cua sov txheej tiv thaiv kom tsis txhob poob dej; (5) Txheeb xyuas nws lub ntim thiab hnub xa khoom, thiab ua qhov kev sim ua ntej los xyuas seb nws puas siv tau; (6) Tshawb xyuas cov dej tsim kho, siv cov kais dej. Yog tias cov khoom saum toj no tsis dhau qhov kev tshuaj xyuas, kev tsim kho yuav tsum tau ua tsuas yog tom qab tsim nyog. Cov khoom siv uas tas sij hawm yuav tsis siv. Thaum lub sij hawm tsim kho, nws yog ib qho tsim nyog los xyuas kom meej tias tsis muaj hluav taws xob tsis ua hauj lwm lossis cuam tshuam ntawm kev tsim kho. 2. Lub template rau refractory castable tsim yuav ua los ntawm steel phaj los yog hardwood board. Cov qauv yuav tsum muaj lub zog txaus, zoo rigidity, tsis muaj duab, tsis muaj kev hloov pauv, tsis muaj slurry to. Cov qauv hlau yuav tsum tau coated nrog tus neeg tso tawm, thiab cov qauv ntoo yuav tsum tau pleev xim rau cov xim tsis muaj dej. Cov qauv siv rov qab yuav tsum tau muab ntxuav ua ntej, thiab tom qab ntawd pleev xim ua ntej siv. 3. Cov dej ntxiv yuav tsum tau tswj nruj me ntsis raws li cov lus qhia rau kev siv, feem ntau 7 feem pua -9 feem pua yog qhov zoo dua, thiab yuav tsum tsis txhob tshaj qhov txwv. Raws li qhov kev pom zoo ntawm kev ua haujlwm ntawm kev tsim kho, cov dej ntxiv yuav tsum tsawg dua. 4. Lub sijhawm sib tov yuav tsum tsis pub tsawg tshaj 15 feeb. Siv lub tshuab sib xyaw ua ke thaum ua haujlwm. Thaum nplawm, nws raug nquahu kom qhuav sib xyaw ua ntej, tom qab ntawd ntxiv 80 feem pua dej thiab do, thiab tom qab ntawd ntxiv cov dej ntxiv maj mam thiab txuas ntxiv stirring raws li qib ntawm dryness thiab ntub dej kom txog thaum muaj kev ua haujlwm zoo sib xws. Ntxuav lub tov khoom ua ntej thaum sib tov sib txawv castables. 5. Yuav tsum siv tag nrho cov thoob thiab lub hnab. Lub stirred refractory castable feem ntau yog siv li ntawm 30 feeb. Hauv qhov chaw ua haujlwm kub thiab qhuav qhuav, lub sijhawm no yuav tsum tau luv kom tsim nyog. Cov castables uas tau pib tsim los yog txawm tias agglomerated yuav tsum tsis txhob nchuav rau hauv pwm, thiab yuav tsum tsis txhob tov nrog dej ua ntej siv. 6. Tom qab nchuav rau hauv cov pwm pwm, nws yuav tsum tau stratified nrog vibrating pas nrig tam sim ntawd, qhov siab ntawm txhua txheej yuav tsum tsis txhob siab tshaj 300mm, thiab qhov vibration spacing yuav tsum yog li ntawm 250mm. Sim kom tsis txhob kov cov thauj tog rau nkoj thaum muaj kev vibrations, thiab tsis txhob cuam tshuam ntev lossis hnyav hauv tib qhov chaw. Tom qab pom qhov chaw reflow, lub vibrating pas nrig yuav tsum maj mam thim kom tsis txhob muaj kev sib cais thiab voids. Tom qab lub pouring tiav lawm, lub pouring lub cev yuav tsis tau compressed thiab shaken ua ntej solidification. 7. Thaum pouring ib cheeb tsam loj, kev tsim kho yuav tsum tau muab faib ua blocks. Qhov tsim nyog thaj chaw ntawm txhua qhov chaw nchuav yog li 1.5m2. Expansion pob qij txha yuav tsum tau teem raws li tus tsim thiab yuav tsum tsis txhob muab tshem tawm. Expansion pob qij txha yuav tsum tau sab laug nyob rau hauv lub ncua sij hawm ntawm lub anchors. 8. Tom qab qhov chaw qhuav lawm, tam sim ntawd npog qhov raug nrog cov yas zaj duab xis los yog straw hnab. Tom qab qhov pib qhov chaw tuaj txog, nws yuav tsum tsis tu ncua sprinkled nrog dej rau kev saib xyuas kom cov av noo. Lub sijhawm kho yuav tsum yog tsawg kawg yog ob hnub, thiab dej yuav tsum nquag txau rau thawj hnub. Tom qab qhov kev teeb tsa zaum kawg, daim ntawv sab tuaj yeem raug tshem tawm mus txuas ntxiv sprinkling thiab txij nkawm, tab sis lub load-bearing formwork yuav tsum tsis txhob raug tshem tawm kom txog thaum lub zog nce mus txog 70 feem pua. 9. Tom qab lub template raug tshem tawm, lub pouring lub cev yuav tsum tau soj ntsuam nyob rau hauv lub sij hawm. Cov teeb meem zoo xws li honeycomb, tev thiab voids yuav tsum tau kho thiab kho raws sijhawm. Thaum qhov teeb meem loj heev, qhov tsis xws luag yuav tsum tau chiseled tawm kom nthuav tawm cov anchorage, thiab tom qab ntawd tau ntim nrog cov khoom zoo tib yam tamping kom txuas ntxiv kev saib xyuas. Nws yog txwv tsis pub siv cov cement mortar kom flatten los npog qhov teeb meem.
