Nyob rau xyoo tas los no, muaj ib qho teeb meem txhawj xeeb tau tshwm sim txog kev koom tes ntawm cov ntaub ntawv rwb thaiv tsev sab nraud ua "cov neeg koom tes hauv hluav taws." Qhov kev txhawj xeeb no tau hais txog qhov xav tau ceev ceev rau kev tiv thaiv hluav taws ntau dua hauv cov ntaub ntawv rwb thaiv tsev thiab kev tswj hwm nruj dua los tiv thaiv cov xwm txheej uas yuav ua rau puas tsuaj loj heev. Cov kws tshaj lij thiab cov nom tswv tam sim no tab tom hais kom lub tebchaws saib xyuas thiab tswj hwm kev tsim khoom thiab kev muab cov khoom siv refractory, hais txog qhov tseem ceeb ntawm kev xaiv cov ntaub ntawv zoo los tiv thaiv hluav taws los ntawm kev rwb thaiv tsev tsis zoo.
Muaj ntau daim ntawv tshaj tawm thiab kev tshawb nrhiav txog cov hluav taws hauv tsev tau qhia txog lub luag haujlwm tseem ceeb ntawm cov ntaub ntawv rwb thaiv tsev sab nraud. Cov ntaub ntawv no, uas yog los txhawb kev siv hluav taws xob kom zoo dua thiab txhim kho kev rwb thaiv tsev kub, hmoov tsis zoo, cov neeg muag khoom tsis zoo siv lawv cov khoom. Kev siv cov ntaub ntawv rwb thaiv tsev tsis zoo tau ua rau muaj ntau qhov xwm txheej hluav taws kub, qhov twg cov ntaub ntawv no ua rau muaj hluav taws kub ntau ntxiv, qhov twg cov ntaub ntawv no ua rau muaj hluav taws kub ntau ntxiv thiab ua rau muaj kev phom sij rau ntau tus neeg lub neej thiab khoom vaj khoom tsev.
Yuav kom daws tau qhov teeb meem loj no, cov kws tshaj lij thiab cov nom tswv hauv kev lag luam tab tom hu kom muaj kev nqis tes ua tam sim ntawd los txo qhov kev phom sij ntawm hluav taws uas cuam tshuam nrog cov ntaub ntawv rwb thaiv tsev. Cov tub ceev xwm tau raug txhawb kom tsim cov cai nruj dua rau kev tsim khoom, kev muag khoom, thiab kev siv cov ntaub ntawv rwb thaiv tsev, yog li ntawd tsuas yog cov khoom zoo, tiv taus hluav taws cov khoom lag luam raug coj los rau hauv kev ua lag luam. Tsoomfwv kuj raug txhawb kom koom tes nrog cov kws tshaj lij hauv kev lag luam, ua kev tshuaj xyuas thiab kev ntsuam xyuas zoo kom tshem tawm cov khoom siv thiab cov neeg muag khoom tsis zoo.
Vim muaj tej xwm txheej nyuaj siab no, nws yog ib qho tseem ceeb heev uas yuav tsum tau muab qhov tseem ceeb tshaj plaws rau kev siv cov kev ntsuas tiv thaiv hluav taws kom zoo. Nws yog ib qho tseem ceeb rau cov kws tshaj lij kev tsim kho, cov kws kes duab vajtse, thiab cov neeg tsim kho kom xaiv cov ntaub thaiv hluav taws uas paub tias lawv tiv taus hluav taws zoo heev. Qhov no yuav tiv thaiv cov teeb meem loj uas tshwm sim los ntawm kev siv cov khoom rwb thaiv tsev tsis zoo. Yog li ntawd, kev xaiv thiab kev siv cov ntaub thaiv hluav taws kom zoo yuav txo tau qhov kev pheej hmoo ntawm hluav taws thiab thaum kawg cawm tau neeg txoj sia.
Yog li ntawd, nyob nruab nrab ntawm cov kev txhawj xeeb no, qhov kev tsom teeb tam sim no hloov mus rau qhov kev daws teeb meem tseem ceeb - kev siv cov cov cenosphere ua cov khoom siv refractory. Cenospheres muaj cov khoom zoo kawg uas ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau ntau yam cov castables refractory sib dua, cov tshuaj nplaum uas tsis kub hnyiab, thiab lwm yam khoom siv hauv tsev. Lawv txoj kev tiv thaiv hluav taws zoo heev, ua ke nrog lawv lub peev xwm ua kom lub cev tsis hnyav thiab rwb thaiv tshav kub, tuaj yeem pab txhawb kev nyab xeeb thiab lub neej ntev ntawm cov qauv.
Xaus lus, qhov kev txhawj xeeb ntawm qhov xwm txheej uas cov ntaub ntawv rwb thaiv tsev sab nraud ua haujlwm ua "cov neeg koom tes hauv hluav taws" tau ua rau muaj kev hu kom muaj kev tswj hwm thiab kev cai nruj dua los tawm tsam cov khoom tsis zoo. Qhov xav tau ceev ceev kom muab qhov tseem ceeb rau kev xaiv cov ntaub ntawv rwb thaiv tsev zoo, tiv taus hluav taws yog qhov tseem ceeb rau kev tiv thaiv kev puas tsuaj ntxiv. Ntxiv mus, kev siv Cenospheres ua cov khoom siv refractory zoo tshaj plaws ua haujlwm ua qhov kev daws teeb meem zoo rau kev lag luam kev tsim kho. Los ntawm kev siv cov microspheres no hauv cov khoom siv refractory castables thiab lwm yam khoom siv hauv tsev, peb tuaj yeem ua kom muaj kev nyab xeeb dua, cov qauv tiv taus hluav taws ntau dua. Yog xav paub ntxiv lossis muaj lus nug, thov hu rau peb. Ua ke, peb tuaj yeem siv zog rau yav tom ntej muaj kev nyab xeeb dua.
