Nyob rau hauv lub khob melting rauv, cov nplaim hluav taws tsim los ntawm combustion ntawm cov roj ntws nyob rau hauv ib tug turbulent yam, muaj zog thiab haib, thiab muaj ib tug tej yam scouring nyhuv. Qhov kub siab tshaj plaws ntawm cov nplaim taws yog 1500 ~ 1600 degree, thiab hloov nrog lub sijhawm. Tshwj xeeb tshaj yog thaum thim rov qab, qhov kub thiab txias fluctuates heev. Cov nplaim hluav taws kuj sib xyaw nrog cov plua plav, alkali vapor, boron vapor, lead vapor thiab carbon hais. Qhov chaw masonry kuj dais ib qho kev thauj khoom ntawm qhov kub thiab txias. Cov cib hauv qhov chaw nplaim taws muaj xws li lub ru tsev kiln, lub mis phab ntsa thiab qhov cub me me. Cov yam ntxwv kev puas tsuaj ntawm txhua feem thiab cov khoom siv cib refractory siv tau piav qhia hauv qab no.
Cib rau kiln ru tsev thiab lub mis phab ntsa
Cov yam ntxwv kev puas tsuaj ntawm ib feem ntawm lub cib lub cev yog corrosion (feem ntau yog alkaline sulfate condensation, tsim honeycomb corrosion) thiab hlawv, yog li nws yog ib qho tsim nyog yuav tsum siv cov ntaub ntawv uas ruaj khov heev rau alkali vapor ntawm qhov kub thiab txias thiab muaj qhov kub thiab txias. tsis kam. Lub koov loj ntawm lub qhov cub melting qhov chaw taws teeb txais kev ua haujlwm zoosilica cib. Lub 33 # fused zirconium corundum cib siv nyob rau hauv lub mis phab ntsa ntawm lub melting ib feem muaj zoo thermal poob siab tsis kam ntawm qhov kub ntawm ntau tshaj 1200 degree. Nyob rau tib lub sijhawm, lawv muaj kev tiv thaiv corrosion zoo rau alkaline vapor thiab feem ntau cov plua plav hauv cov khoom siv.
Lub qhov cub siab muaj qee yam cuam tshuam rau kev siv cov refractory cib linings nyob rau hauv kev sib cuag nrog cov nplaim taws. Thaum lub qhov cub kub siab dhau lawm, cov nplaim hluav taws kub hnyiab ntawm cov refractories cib, tshwj xeeb tshaj yog cov pob qij txha cib. Cib pob qij txha yog qhov tsis muaj zog tshaj plaws ntawm tag nrho cov hluav taws kub refractory cib hauv ob sab phlu, thiab lawv feem ntau eroded maj mam raws cov pob qij txha. Yog li ntawd, nyob rau hauv kev tsim kho cov ntaub ntawv refractory, thaum xaiv cov khoom uas muaj kev ua tau zoo, cov av nkos refractory nrog kev ua tau zoo yuav tsum tau xaiv, thiab qhov dav ntawm cov pob qij txha yuav tsum tau txo kom tsawg los txhim kho huab cua nruj.
Cib rau pem hauv ntej phab ntsa
Cov phab ntsa pem hauv ntej yog ib feem tsis muaj zog ntawm cov iav melting rauv tank kiln. Muaj peb hom kev puas tsuaj rau nws, uas yog, kev yaig ntawm cov batch, thermal shock thiab nplaim taws yaig. Tam sim no, qhov no feem ntau siv 33 # fusedAZS brickslos yog sintered AZS cib, thiab tseem muaj cov khoom zoo ntawm cov silica cib thiab sintered AZS cib. Ntxiv nrog rau kev siv cov cib zoo, cov phab ntsa pem hauv ntej kuj yuav tsum tau ua ke nrog cov cua txias.
Cib rau lub cub tawg me me
Cov yam ntxwv kev puas tsuaj ntawm cib rau cov cub tawg me me tuaj yeem ua tiav raws li hauv qab no: cov pa roj flue nrog cov hmoov, alkali vapor thiab cov nplaim hluav taws kub ib ntus txav mus los ntawm kev kub ceev, uas coj cov cua sov siab, qhov kub thiab txias hloov pauv, huab cua hloov thaum rov qab, scouring ntawm nplaim taws thiab yaig ntawm alkali hmoov. Yog hais tias qhov combustion tsis tiav hauv qhov chaw nplaim taws, thiab cov nplaim hluav taws tseem kub hnyiab hauv qhov cub me me thaum lub sij hawm tempering, overheating yuav tshwm sim. Kev yaig ntawm lub cib seams ntawm lub cub tawg me me arch bricks yuav ua rau lub dab dej ntawm ib qho arch cib thiab loosening ntawm ko taw. Qhov kub ntawm qhov sib txawv ntawm sab hauv thiab sab nrauv ntawm lub nozzle cib yog qhov loj heev, thiab nws yooj yim rau tawg thiab tev tawm. Yog tias nws poob rau hauv cov kua iav, nws yuav ua rau muaj qhov tsis xws luag. Raws li cov yam ntxwv kev puas tsuaj saum toj no, cib rau cov cub tawg me me yuav tsum tau tiv taus kub kub, yaig, scouring, thiab muaj qee qhov kev tiv thaiv thermal shock.
Tam sim no, ntawm cov cib refractory rau cov cub tawg me me, qhov cub hluav taws xob arch cib, lub qhov cub me me inclined arch top txheej cib, lub cub tawg me me hauv qab phaj cib thiab cov cub me me nplaig cib yog cov cib puas yooj yim tshaj plaws, thiab tseem yog qhov tsis muaj zog. ntawm lub pas dej ua ke. Lub crater arch bricks, crater sab phab ntsa cib, hauv qab phaj cib, inclined arch top txheej cib, nplaig cib thiab nozzle cib yog ua los ntawm fused AZS cib (qhov tsis muaj zog tshaj yuav tsum tau ua los ntawm fused AZS41 cib), tab sis yuav tsum xyuam xim rau. qhov tshwm sim ntawm cov pob zeb tawg vim yog siv lead ua hloov pauv hauv qhov ntau ntawm 1000-1200 degree . Hauv qab phaj cib kuj tuaj yeem ua los ntawm sintered ntom corundum cib. Qhov cub me me txoj kab nqes koov thiab kab rov tav channel arch feem ntau yog ua los ntawm silica cib.
