Thaum tsimrefractory bricksrau steelmaking hluav taws xob furnaces, kev tsim kho yuav tsum tau ua raws li cov hauv qab no specifications:
Lub qhov cub hauv qab yuav tsum tau staggered thiab qhuav-ntev, thiab cov hluav taws cib pob qij txha yuav tsum tau ntim nrog cov hmoov refractory. Lub longitudinal ntev seams ntawm sab sauv thiab sab cib yuav tsum staggered 30 degree ~ 60 degree. Sab saum toj cib ntawm lub cub tawg hauv qab yuav tsum tau pw vertically.
Lub cub tawg hauv qab ntawm DC arc rauv yuav tsum tsis txhob muaj kab rov tav thiab ntsug expansion pob qij txha. Lwm qhov chaw yuav tsum muaj cov pob qij txha txuas ntxiv raws li xav tau.
Kev teeb tsa ntawm cov sawb electrode ntawm lub qhov cub hauv qab yuav tsum yog ntsug, thiab ntsug tso cai sib txawv ntawm nws qhov siab tag nrho yuav tsum yog 0 ~ 1mm.
Lub thickness ntawm lub cib seam ntawm sab nrauv shielding cib ntawm lub sawb electrode yuav tsum tsis txhob ntau tshaj 0.5mm. Cov nplaum nplaum ntawm ob txheej ntawm cov thaiv thaiv cib yuav tsum tau ua kom sib npaug, thiab cov ntaub thaiv npog sab saud thiab qis yuav tsum tau ua kom nruj.
Cov cib thaiv kev tiv thaiv yuav tsum nruj ua ke nrog cov sawb electrode.
Lub cathode ramming ntawm lub cub tawg hauv qab yuav tsum tau txhawb nqa los ntawm pwm. Qhov kev sib cuag nrog cov sawb electrode shielding cib yuav tsum tau ua kom zoo, thiab cov khoom siv refractory ramming nyob rau hauv qhov zawj ib feem ntawm shielding cib yuav tsum ntom thiab sib koom ua ke yuav tsum nruj. Kev tsim kho cov ntaub ntawv refractory ramming yuav tsum tau ua raws li cov kev cai ntawm Tshooj 4.5 ntawm GB 50211-2014.
Lub refractory cib ntawm lub qhov slag yuav tsum tau pw synchronously nrog lub slag qhov dab tshos. Ib qhov sib txawv yuav tsum tau sab laug ntawm lub slag qhov cib thiab lub dab tshos cib raws li kev tsim qauv. Tom qab lub ramming ntawm lub cub tawg hauv qab txheej ua hauj lwm tiav lawm, qhov sib txawv yuav tsum tau sau thiab compacted nrog refractory ramming cov ntaub ntawv.
Sab hauv phab ntsa ntawm lub qhov slag yuav tsum tau khaws cia kom tiaj tus, thiab lub thickness ntawm annular seam yuav tsum tsis txhob ntau tshaj 1 hli.
Cov khoom qhuav ntawm lub cub tawg hauv qab txheej yuav tsum tau rammed nyob rau hauv cov khaubncaws sab nraud povtseg, thiab lub thickness ntawm txhua paving yuav tsum tsis txhob ntau tshaj 200mm. Lub cub tawg zoo yuav tsum tau tswj los ntawm tus qauv thaum lub sij hawm ramming txheej txheem.
Lub qhov hluav taws xob steel yuav tsum tau ua tib zoo nteg thiab rammed, thiab yuav tsum ua raws li lub kaum sab xis tsim.
Thaum tso lub qhov cub rauv, lub nplhaib npog lub qhov cub yuav tsum tau muab tso rau hauv tiaj tus. Lub qhov cub npog cib yuav tsum tau pw nrog staggered seams, thiab cov refractory cib nyob ib ncig ntawm yuav tsum nyob ze rau lub cub tawg lub nplhaib.
Thaum refractory castable prefabricated qhov chaw siv rau ntawm lub ru tsev rauv, lub stacking, lifting, hoisting thiab masonry ntawm lub prefabricated qhov chaw yuav tsum tau ua raws li cov kev cai ntawm Tshooj 4.3.14 txog 4.3.18 ntawm GB 50211-2014.
Lub masonry nyob ib ncig ntawm lub electrode chaw nres nkoj thiab nws ib puag ncig yuav tsum tau ua tib zoo ua tiav thiab masonry, thiab txoj kab uas hla ntawm lub electrode chaw nres nkoj cib nplhaib yuav tsum ua raws li cov kev cai tsim. Qhov tso cai sib txawv ntawm qhov kev ncua deb ntawm qhov chaw ntawm txhua qhov chaw nres nkoj electrode yuav tsum yog ± 5mm0
Lub qhov cub phab ntsa qhov rooj cib yuav tsum tau muab tso rau hauv qhov ntev ntawm 1m mus rau 2m ntawm ob sab ntawm qhov chaw nres nkoj slag, thiab lub qhov rooj sab saud thiab sab qis yuav tsum tau staggered los ntawm 4 mus rau 5 cib. Qhov dav ntawm lub qhov rooj ua tiav cib yuav tsum tsis txhob tsawg dua 2/3 ntawm qhov dav cib qub.
Thaum siv cov ntaub ntawv qhuav ua lub cub tawg hauv qab ua haujlwm txheej, 1mm mus rau 2mm tuab steel phaj yuav tsum tau siv los npog thiab tiv thaiv tom qab ramming.
