Lub hauv ob sab phlu ntawm lub qhov cub refining tuaj yeem muab faib ua plaub ntu: lub qhov cub hluav taws xob, phab ntsa kawg, lub qhov cub qhov cub, thiab qhov chaw nres nkoj pa taws. Lub thoob muaj redox qhov, sampling qhov thiab lwm yam qhib. Cov phab ntsa kawg tau muab faib ua ob hom: cov phab ntsa tiaj tus kawg thiab cov phaj phaj kawg. Lub thickness ntawm lub cub tawg yog txawv raws li qhov loj ntawm lub cub tawg, feem ntau ntawm 300 ~ 425mm.
1. Phab ntsa brickwork
(1) Lub tiaj tiaj phab ntsa ua haujlwm saum npoo yuav tsum tau tsim los siv txoj kev sib tw kab rov tav sib koom ua ke bricklaying. Ib txheej ntawm 65mm tuab txheej txheem av nplaum refractory cib yog nteg ncaj nruab nrab ntawm lub plhaub thiab txheej ua haujlwm. Cov txheej txheem ua haujlwm (magnesia chrome cib) nyob rau hauv lub voj voog ntawm phab ntsa kawg uas cov phab ntsa kawg hu rau lub tog raj kheej hauv ob sab phlu yuav tsum tau thim rov qab rau hauv lub qhov cub lub ntsej muag. 50mm (knotted 50mm magnesium grid ramming khoom). Cov kab slag yog semi-rebonded magnesia-chromium bricks, thiab lwm yam yog sib txuas ncaj qha magnesia-chromium cib. Muab nees manure cardboard nyob rau hauv ntsug expansion pob qij txha kom nqus cov expansion ntawm bricks. Cov pob qij txha ntsug ntawm txhua txheej yuav tsum staggered thiab yuav tsum tsis txhob nyob ntawm txoj kab ncaj nraim. Rau kab rov tav expansion pob qij txha, raws li qhov tsim nyog yuav tsum tau, muab ib txheej ntawm nees manure ntawv rau txhua txhua 5 mus rau 6 txheej. Ncua qhov nthuav ntawm cib; sau cov pob qij txha ncig nrog cov khoom siv magnesia-chromium ramming.
(2) Phab ntsa zoo li lub tais.
Qhov chaw ua hauj lwm ntawm lub phaj-zoo li tus kawg phab ntsa yog tsim los siv txoj kev kab rov tav bricklaying. Daim ntawv masonry yog tib yam li rau cov phab ntsa tiaj tus. Cov khoom siv cib yog tib yam li cov phab ntsa tiaj tus, thiab cov txheej txheem masonry thiab expansion sib koom ua ke kev kho mob yuav tsum yog tib yam li lub tiaj tus phab ntsa. Qhov txawv yog tias cov duab ntawm lub cib sib txawv, sab hauv yog du, thiab tsis muaj cov hniav tsis raug.
2. Rauv chim
Ua ntej tso cib rau ntawm lub tog raj kheej, siv cov khoom siv brine magnesia ramming los pound ib 50mm tuab mus rau qhov cub hauv ob sab phlu, los yog nteg ib txheej ntawm 65mm tuab txheem av nplaum refractory cib ncaj nraim. Magnesia-chromium cib ntawm qhov redox qhov thiab cov qhov sampling yog tsim nrog cov pob qij txha ncaj los pab txhim kho hauv zos thiab hloov.
Lub cib hom yog tsim tshwj xeeb raws li lub qhov cub specifications (lub tog raj kheej txoj kab uas hla). Lub cib loj ntawm Φ4530mm lub tog raj kheej cib yog: 380mm × 150mm × 115/91mm thiab 75/59mm. Qhov dav ntawm staggered cib ntawm qhov kawg yog 225mm thiab lub thickness yog 115/91mm thiab 90/70mm. Thaum kawg, zawm nws nrog ib lub cib xauv.
Expansion pob qij txha yuav tsum tau teem raws li masonry tsim yuav tsum tau. Cib hauv ob sab phlu ntawm refining rauv: circumferential seams, ntxig ib 2 hli tuab nees manure cardboard txhua 15 cib; longitudinal seams, ntxig ib 2 hli tuab nees manure cardboard txhua ob lub cib. Cov duab thiab qhov ntev ntawm cov duab los qhia yog tib yam li qhov sib txawv ntawm qhov ntev ntawm cov kab ntsug ntsug-zoo li cov cib tau muab tso rau.
3. Cib tso rau ntawm qhov cub qhov ncauj
Lub cib ua haujlwm ntawm lub qhov cub refining lub qhov ncauj yog qhov tsis muaj zog tshaj plaws ntawm tag nrho cov txheej txheem ntawm lub cub tawg, tshwj xeeb tshaj yog kev sib tshuam ntawm lub qhov cub qhov cub thiab lub tog raj kheej kheej kheej, uas muaj cov duab zoo. Yog li ntawd, kev sib koom ua ke ntawm lub qhov cub lub qhov ncauj kaw cov cib, lub qhov cub lub qhov ncauj brickwork thiab lub tog raj kheej brickwork, koj yuav tsum tau ceev faj thaum tsim cov masonry. Thaum lub masonry muab tso rau hauv lub qhov cub qhov ncauj, nws yuav tsum tau ua symmetrically ntawm ob sab mus rau qhov chaw nyob rau tib lub sij hawm. Cov pob qij txha radial ntawm lub arch bricks yuav tsum coincide nrog lub vojvoog kev taw qhia, txwv tsis pub yuav muaj misaligned hniav los yog kaum pob qij txha. Thaum tso bricks, pre-ntev yuav tsum tau siv ua ntej los txiav txim seb tus nqi ntawm cov locking bricks yuav tsum tau ua.
Xauv refractory bricks yuav tsum tau muab faib symmetrically thiab tusyees raws li txoj kab nruab nrab ntawm lub vault. Xauv cib 2 yuav tsum muab tso rau tib lub sij hawm li cib 1 thiab 3 ntawm ob sab, thiab ces tsav nrog ib tug ntoo rauj, tsis yog nrog rauj hlau. Expansion pob qij txha yuav tsum tau teem raws li masonry tsim yuav tsum tau los yog raws li expansion tus nqi muab los ntawm refractory khoom tsum.
4. Masonry ntawm lub qhov hluav taws xob tooj liab
Muaj ob hom tooj liab qhov hluav taws xob cib: ib hom drilled thiab ua ke, raws li qhia hauv daim duab 4. Nyob rau hauv daim duab, 1, 2, thiab 3 yog ua los ntawm 6 composite bricks, los yog lawv tuaj yeem tsim nrog ib qho drilled cib. . Txawm hais tias daim ntawv ntawm cib masonry yog siv rau lub qhov hluav taws xob tooj liab, nws yuav tsum tau ua kom ntseeg tau tias qhov chaw ntawm lub qhov hluav taws xob tooj liab yog ua raws li qhov nruab nrab ntawm lub qhov hluav taws xob tooj liab ntawm lub plhaub kom ntseeg tau tias lub kaum sab xis yuav tsum tau ua los ntawm kev tsim thiab qhov yuam kev tsis yog. ntau dua 2 hli, txwv tsis pub nws yuav tsis tsim nyog.
5. Cua qhov hluav taws xob
Lub qhov hluav taws xob cua yog tsim los ntawm ob lub qhov hluav taws xob refractory cib thiab 8 nyob ib puag ncig cov cib loj. Vim yog cov cua txias thaum lub sij hawm kho dua tshiab, cov cib tuyere muaj lub neej luv dua li lub cub tawg chim thiab feem ntau yuav tsum tau hloov, yog li cov masonry yuav tsum tau yooj yim disassembly thiab sib dhos.
