Lub hauv paus ntsiab lus ntawm kev xaiv cov txiv qaub kiln ( ntsug kiln) yuav tsum ua ntej resistant rau alkali, zoo ntom thiab muaj zog lub zog, thiab kuj rau refractory bricks nrog muaj zog degradation. Ntau cov txiv qaub kiln-resistant bricks cov neeg siv teb rau bricks nquag.
Ib qho yog kev xaiv ntawm cov cib refractory, thiab lwm qhov yog cov masonry ntawm cov txiv qaub kiln qhov cub. Cov tshauv seam ntawm refractory hluav taws cib yog qhov tsis muaj zog txuas tom qab lub qhov cub phab ntsa mounts. Thaum lub cub tawg tau tsim, qhov pore tus nqi ntawm refractory cib masonry yog loj, qhov khoob ntawm cov cib yog loj -alkaline hlau oxide, thiab cov pa roj carbon tsom xam. Kev loj hlob ntau dhau ntawm ntug dej ntws thaum lub sijhawm ua haujlwm yuav ua rau qhov kub ntawm qhov kub ntawm cov phab ntsa ntawm lub qhov cub kom siab dhau, tsim cov xwm txheej rau qhov kub thiab txias, yog li ntawd cov cib raug tev tawm ntxov.
Alkaline hlau oxides thiab Mo Lai pob zeb cov khoom xyaw hauv cov hluav taws kub-resistant bricks kuj ua rau ntim expansion. Muaj ob qhov chaw ntawm alkaline hlau oxides, uas yog los ntawm cov roj thiab cov hom los ntawm hluav taws kub nws tus kheej. Cov alkaline hlau oxides thiab SiO2 cov tshuaj tiv thaiv nyob rau hauv lub refractory cib react los tsim ib tug compound ntawm uas tsis muaj melting kub, ua rau cov qog nqaij hlav, ua rau puas tsuaj rau hauv ob sab phlu. Lub Mo Lai Pob Zeb Peb Txhuas Silicon (3AL2O3.2SIO2) nyob rau hauv alkaline hlau oxide thiab cov hluav taws kub refractory cib reacts los tsim cov pob zeb poov tshuaj (K2O.AL2O3.2SIO2) Dawb garnet (K2O.AL2O3.4SIO2), nrog rau 30 feem pua ~ 50 feem pua ntawm qhov ntim nthuav dav, thiab qhov kub thiab txias ntawm cov pob zeb poov tshuaj yog li 1100 degrees Celsius, uas cuam tshuam rau qhov tsis kam ntawm cov khoom siv refractory. Qhov tshwm sim yog ua rau lub cub tawg tev tawm. Lub ncuav ntawm Wei Ran Belt kom ntseeg tau tias qhov kub thiab txias tshwm sim los ntawm qhov kub thiab txias hauv qhov qis thiab sab saud, thiab qhov kub ntawm qhov cub hauv cov yeeb nkab tau zoo tuaj. Kev tshawb fawb ntawm Lub Tsev Haujlwm Saib Xyuas Kev Tshawb Fawb ntawm Cov Khoom Siv Hluav Taws Xob: Kev puas tsuaj ntawm cov hlau alkaline yog qhov ua rau muaj kev puas tsuaj rau cov cib hauv ob sab phlu, thiab nws suav txog li 40 feem pua ntawm kev puas tsuaj. Kev tshem tawm thiab tshem tawm alkali ntawm raw cov ntaub ntawv rau cov ntaub ntawv refractory yog ib qho tseem ceeb heev. Nws yooj yim dua kom tshem tawm cov hlau, tab sis nws yog qhov nyuaj dua kom tshem tawm cov alkali impurities K2O / NA2O / R2O. R2O yog lub ntsiab lus ntawm tus nqi ntawm oxides. Qhov no alkaline hlau oxide impurities tuav raw cov ntaub ntawv.
Kev puas tsuaj thermal
Qhov kub ntawm qhov chaw ua haujlwm ntawm lub pob zeb refractory yog ze rau qhov kub ntawm cov pa roj marginal, qhov kub ntawm qhov chaw ua haujlwm yog ze rau 1400, thiab qhov kub ntawm cov hluav taws kub refractory cib yog tsawg, thiab qhov kub ntawm qhov sib txawv ntawm ob. yog siab tshaj 400 degrees. 40MPa, yog li koj yuav tsum siv cov khoom siv hluav taws xob siab nrog cov thermal conductivity. Kev nthuav dav ntawm thermal stress tshwm sim los ntawm refractory cib cua sov txav zoo li txias ntawm qhov kub thiab txias, uas ua rau lub qhov cub phab ntsa yooj yim tsim ib ncig tawg. Cov kev cai ntawm cov hluav taws kub refractory cib hauv ob sab phlu yog tias ciam teb cua sov yog txias vim hais tias cov hlau plhaub thiab cov khoom siv thermal rwb thaiv tsev txias, yog li cov vuas hluav taws-resistant cov vuas uas muaj thermal conductivity yuav tsum tau xaiv.
Mechanical scouring
Mechanical flushing thiab hnav yog hais txog cov dej ntws tawm ntawm lub cub tawg lub tog raj kheej sab hauv slag thiab hlau ntws mus rau lub qhov cub phab ntsa, cov pa roj tsim los ntawm txoj siv hluav taws xob tsim los ntawm cov hmoov ntawm lub cub hluav taws xob hauv ob sab phlu, thiab cov khoom siv hluav taws xob los ntawm sab saum toj. qhov cub hauv qhov cub. Kev hnav ntawm lub qhov cub hauv ob sab phlu.
