Cov chaw sib txawv ntawm cov khib nyiab yuav tsum muaj ntau homRefractorters CastablesCov. Hauv qab no yog qee hom thiab lawv cov khoom siv:
1. Khib hauv Inlet: hnav cov khoom siv ua pov tseg feem ntau yog siv. Cov khib nyiab hauv ntu no hu rau hauv ob lub refractory, uas yuav tsim kev cuam tshuam thiab kev sib txhuam. Ntawm ib sab tes, nws yog radiated los ntawm qhov kub nyob rau hauv lub cub tawg, thiab ntawm qhov tod tes, nws ncaj ncaj rau hauv kev sib cuag nrog cov khib nyiab thiab ntxaum. Cov refractory txheej khoom siv yog yuav tsum tau hnav zoo thiab thermal poob siab kuj. Feem ntau, kev ua kom puam yuav tsum tau ua kom dhau 900 degree, cov thermal poob siab tshaj lossis sib npaug nrog 20 zaug, thiab cov txheej txheej ua kom tuab yog} hli} hli.
2. Hluav taws xob chamber: Refractory castables muaj cov SIC feem ntau siv. Vim tias cov pa hluav taws kub tau ncaj qha rau cov chaw txias hluav taws xob, lub tshuab hluav taws xob kom yooj yim rau kev ua kom sov rau saum npoo ntawm cov dej-txias phab ntsa thiab daim cooking. Nyob rau tib lub sijhawm, daim ntawv sau ua ke yooj yim kom ua rau muaj kev kub siab-kub corrosion ntawm cov yeeb nkab dej. Cov khoom siv SIC yog tiv taus slag yaig thiab muaj cov cua sov condal thiab muaj peev xwm ua kom lub peev xwm nqus hluav taws xob tsim nyog kom txias roj. Lub thickness ntawm txheej refractory yog 80-100 hli.
3. Lwm cov yeeb nkab tog qhib qhib: xws li cov ntu uas muaj tshuaj tsuag rau hauv cov yeeb nkab tog, thiab lwm yam. Vim hais tias tus cawv ntawm cov khoom txau nruab nrab, cov ntaub ntawv refractory nyob rau hauv cov seem no yuav tsum muaj kev ua kom tsim nyog ua kom tsim nyog, zoo thermal poob siab thiab kev tsim kho.
4. Theem nrab kev sib xyaw Chamber ntawm gasification melting rauv taws ua kom sov: qhov flue roj kub ntawm no yog siab li {1}} degree. Raws li qhov kub npau taws thiab cov mob ntsws ntau tshaj 1200 degree, nws yog ib qho tsim nyog los xaiv chrome corundum refractist cov khoom siv nrog slag yaig. Raws li qhov kub thiab txias corundum cov ntaub ntawv muaj 15% {{}}}}}}% Criao₃ raug xaiv, thiab cov ntaub tuab} mm.
5 Ntxiv rau kev ua tau zoo siab, qhov Castable muaj qee qhov kev nthuav dav ntawm cov pa taws kub thiab siv cov cua sov thiab siv rau kev puas tsuaj ntawm cov cua sov phab ntsa. Nyob rau tib lub sijhawm, lub zog tag nrho ntawm cov cua sov lub cev yog qhov zoo heev tom qab cov khoom pov tseg.
6. Qhov chaw nrog cov roj acid tiv thaiv: acidic roj yuav tsim tawm thaum lub sij hawm khib nyiab, ua rau cov kua qaub rau qee qhov. Nyob rau lub sijhawm no, acid-resistant castables tuaj yeem siv. Acid-resistant castumts yog ua los ntawm cov dej iav ua cov binder, acidic lossis semi-acidic refractory ua ke thiab hmoov me me. Lawv tuaj yeem tiv thaiv corrosion los ntawm acidic media (xws li nitric acid, acetic acid, thiab lwm yam) thaum {4} degree.
