1. Muab piv nrog cov khob yas, cov khob ceramics muaj cov pa phem tsawg dua thiab cov khoom coj los ntawm cov khob yas. Raws li cov kws tshaj lij, kev siv lub khob yas mus ntev yuav ua rau mob qog noj ntshav.
2. Lub khob ceramic tsis muaj teeb meem kiag li, nws yuav tsis zoo li lub khob hlau, thiab muaj peev xwm noj cov hlau tsis zoo hauv kev siv mus ntev.
3. Vim tias muaj lub khob ceramic, cov hlau molten tsis nyob rau hauv kev sib cuag ncaj qha nrog cov pa roj carbon bricks, uas relieves infiltration, erosion, yaig thiab lwm yam kev puas tsuaj ntawm molten hlau thiab alkaline tshuaj rau cov carbon bricks los ntawm cov qauv tsim. , thiab mullite, xim av corundum, thiab lwm yam. Txhua yam yog qib high-qib ceramic cov ntaub ntawv uas tsis tshua muaj thermal conductivity, nrog siab tiv taus yaig thiab yaig. Tshem tawm cov txheej embrittlement ntawm cov pa roj carbon loj.
4. Ua kom qhov kub thiab txias ntawm cov hlau molten thiab txo qhov kub poob: Lub khob ceramic yog ua los ntawm cov khoom siv thermal conductivity tsawg dua li cov pa roj carbon cib, uas ua raws li cov txheej txheem interlayer, yog li txo cov cua sov los ntawm lub cub tawg hauv qab thiab hearth. Raws li txoj cai, cov hlau molten tuaj yeem khaws cia ntawm qhov kub thiab txias, uas tsim kom muaj lub zog txuag hluav taws xob zoo rau kev tsim cov converter hauv cov kauj ruam tom ntej.
5. Ib qho yooj yim rau rewind ua hauj lwm: Vim lub thermal rwb thaiv tsev nyhuv ntawm lub khob ceramic, lub tshav kub poob yog txo nyob rau hauv lub blast furnace shutdown lub sij hawm, uas yog conducive rau restore ib txwm ua hauj lwm thaum rewinding.
6. Tiv thaiv molten hlau to: vim hais tias lub degree isotherm, uas yog, lub solidification kab ntawm molten hlau, yog nyob ze rau lub puab nto ntawm lub cub tawg nyob rau hauv ob sab phlu, thiab tsiv mus nyob ze rau lub puab nto ntawm lub cub tawg. Ntxiv mus, vim qhov zoo me ntsis residual expansion ntawm cov khoom siv refractory, cov pob qij txha cib yog nqaim, yog li cov hlau molten Penetration raug txwv kom qhov kev pheej hmoo ntawm hearth hlawv-los ntawm kev txo qis.
