Dab tsi yog qhov kub-resistant kub ntawm lub teeb rwb thaiv tsev thiab refractory hluav taws cib?
Thermal rwb thaiv tsev txheej ntawm lub qhov cub rauv hauv ob sab phlu yog los tiv thaiv lub plhaub thiab txuag lub zog. Feem ntau ntawm lawv siv lub teeb yuag hluav taws xob rwb thaiv tsev cib, lub teeb zoo rwb thaiv tsev dej fiber ntau daim hlau thiab lwm yam ntaub ntawv rau txheej rwb thaiv tsev.
Vim qhov zoo ntawm lub teeb rwb thaiv tsev thiab cov hluav taws kub refractory bricks los yog pouring gas pores, nws yog feem ntau shrinking thiab deformation thaum cua sov thaum siv. Yog li ntawd, nyob rau hauv qhov sib txawv ntawm qhov kub thiab txias, cov vuas hluav taws xob rwb thaiv tsev los yog cov khoom siv ntawm cov khoom sib txawv yuav tsum raug xaiv los tswj cov txheej txheem thermal rwb thaiv tsev ruaj khov hauv qhov cub. Yog hais tias shrinkage tshwm sim, nws yuav ua rau lub rwb thaiv tsev txheej nyob rau hauv lub qhov cub kom deform los yog tawg thiab ua rau kom lub tshav kub dissipation poob.
Yog li ntawd, thaum xaiv ib lub teeb rwb thaiv tsev thiab refractory hluav taws cib los yog cov khoom siv rwb thaiv tsev, nws tsuas yog nyob ntawm lub peev xwm kom ntsws thiab deform nyob rau hauv qhov kev txiav txim ntawm resisting cua sov. Qhov kub ntawm cov rwb thaiv tsev hluav taws-resistant cib feem ntau yog nce raws li qhov ntim ceev nce. Thaum lub ntim ntom ntom loj heev, lub rwb thaiv tsev rwb thaiv tsev tsis zoo, tab sis qhov kev siv hluav taws xob zoo, tab sis qhov tsawg dhau, uas yog qhov tseem ceeb heev rau tev.
Hauv lwm lo lus, ntawm qhov sib txawv ntawm qhov kub thiab txias, koj yuav tsum xaiv cov rwb thaiv tsev cib los yog cov khoom siv uas haum rau qhov kub thiab txias, lossis cov khoom siv fiber ntau raws li cov txheej txheem rwb thaiv tsev. Cov hauv qab no yog qhov sib txawv ntawm qhov sib txawv ntawm cov hluav taws kub rwb thaiv tsev thiab cov hluav taws kub refractory cib los yog cov khoom siv rau kev siv:
Kev siv kub ntawm cov paj rwb slag yog 600 ° C, thiab qhov kub ntawm kev siv cov ntaub ntawv rwb thaiv tsev perlite yog 50-1000 degree C; qhov kub ntawm calcium silicate board yog 650-1000 degree C; Qhov kub ntawm algae tshav kub rwb thaiv tsev thiab refractory hluav taws cib yog 1000-1200 degree C; refractory ceramic fiber yog 1000-1300 degree C; calcium ntev pob zeb lub teeb cua sov vuas yog haum rau kub 1100-1300 degree C; Lub teeb yuag av nplaum rwb thaiv tsev cib tsim nyog Qhov tsim nyog kub ntawm siab aluminium rwb thaiv tsev cib yog 1350-1500 degree C; lub teeb silicon rwb thaiv tsev cib yog tsim rau 1500-1550 degree C; polycrystalline aluminium fiber siv kub yog 1400-1600 degree C; 1350-1650 degree C; qhov kub ntawm lub teeb corundum cib yog 1650-1800 degree C; aluminium oxide npliag lub plawv pob cua sov vuas 1650-1800 degree C; oxide fiber thiab hollow pob kub thermal rwb thaiv tsev cib yog tsim rau 1800-2000 degree C.
