Cov ntaub ntawv no muaj cov roj ua haujlwm zoo thiab tshuaj lom neeg ruaj khov, thiab tuaj yeem ua haujlwm ruaj khov hauv cov khoom siv roj. Feem ntau siv cov ntaub ntawv refractory xws li hloov tau graphite, ceramic sealing rings, thiab lwm yam.
6. Cov roj cia tank thiab roj additives
Kev txhim kho hluav taws xob txhim kho Cov roj tso tsheb hlau luam yog cov chaw tseem ceeb hauv cov txheej txheem roj cia, thiab cov khoom siv roj ntxiv tuaj yeem txhim kho kev ua haujlwm ntawm cov khoom siv roj. Daim ntawv thov ntawm cov ntaub ntawv refractory nyob rau sab hauv phab ntsa ntawm cov roj cia tso tsheb hlau luam tuaj yeem muab kev tiv thaiv corrosion zoo thiab hnav tsis kam, thiab txuas ntxiv lub neej kev pab cuam ntawm cov roj tso tsheb hlau luam; Nyob rau tib lub sijhawm, qee cov ntaub ntawv refractory tuaj yeem siv los ua ib qho tseem ceeb ntawm cov roj additives los txhim kho cov kev sib txuas thiab kev lag luam ntawm cov khoom siv roj. Feem ntau siv cov ntaub ntawv refractory muaj xws li anti-corrosion txheej, hlau oxides, thiab lwm yam.
7. Cov nplaim hluav taws kub hnyiab thiab tawg-pov thawj cov ntaub ntawv rau kev ua haujlwm hauv av thiab mining
Hauv kev ua haujlwm hauv av thiab qhov chaw mining, feem ntau yog cov nplaim hluav taws kub thiab tawg, yog li cov nplaim hluav taws kub hnyiab thiab cov ntaub ntawv tawg yog xav tau los xyuas kom muaj kev nyab xeeb ntawm kev ua haujlwm. Cov khoom siv refractory muaj cov nplaim hluav taws zoo thiab cov khoom tawg-pov thawj, uas tuaj yeem tiv thaiv kev sib kis ntawm hluav taws thiab qhov tshwm sim ntawm kev tawg. Cov ntaub ntawv no feem ntau yog siv nrog lwm cov ntaub ntawv sib xyaw los muab kev tiv thaiv kev nyab xeeb ntau dua. Feem ntau siv cov ntaub ntawv refractory muaj xws li nplaim hluav taws, hluav taws kub retardant txheej, thiab lwm yam.
8. Combustion chambers thiab kub exchangers nyob rau hauv cov roj refineries
Cov khoom siv refractory Cov combustion chambers thiab cov cua kub sib txawv hauv cov roj refineries yog cov cuab yeej tseem ceeb uas yuav tsum tau tiv taus qhov kub thiab txias ib puag ncig. Cov ntaub ntawv refractory, raws li cov ntaub ntawv ntawm combustion chambers thiab tshav kub exchangers, muaj peev xwm muab tau zoo kub kub kuj thiab corrosion kuj. Cov ntaub ntawv no muaj cov thermal stability siab thiab tsis tshua muaj thermal expansion coefficients, uas tuaj yeem txo qhov kub poob thiab txhim kho cov khoom siv. Cov khoom siv refractory feem ntau muaj xws li refractory cib, refractory pob zeb, thiab lwm yam.
9. Cov ntaub ntawv kub thiab corrosion resistant rau roj cracking units Cov roj cracking unit yog ib qho ntawm cov khoom tseem ceeb nyob rau hauv cov txheej txheem roj thiab yuav tsum tau ua hauj lwm nyob rau hauv high kub thiab corrosive ib puag ncig. Raws li ib qho ntawm cov khoom tseem ceeb ntawm cov roj tawg chav tsev, cov ntaub ntawv refractory yuav tsum muaj qhov kub thiab txias tsis kam thiab corrosion kuj. Cov ntaub ntawv no feem ntau yog siv nrog lwm cov ntaub ntawv sib xyaw kom muaj kev tiv thaiv zoo dua. Feem ntau siv cov ntaub ntawv refractory muaj xws li siab alumina, corundum, thiab lwm yam.
