摘 要:相比鋁酸鹽水泥(CAC),水合氧化鋁(HA)具有更好的高溫性能,可用作鋁熔鑄用內(nèi)襯材料的結(jié)合劑。筆者綜述了HA在鋁熔鑄內(nèi)襯材料養(yǎng)護(hù)過程和熱處理過程中水化產(chǎn)物的組成和結(jié)構(gòu)變化規(guī)律,討論了熱處理過程中HA水化產(chǎn)物演變與內(nèi)襯材料宏觀性能的聯(lián)系,可為高性能澆注料的發(fā)展提供有益參考。

Abstract: Hydratable alumina (HA) is more suitable to be applied as the binder of steel ladle lining refractory, attributed to the better high-temperature performances, compared with calcium aluminate cement (CAC). The composition and structure evolution of HA during the curing and heating process of HA bonded castables is reviewed. The relationship between the HA hydration products evolution and the castable macro-properties is discussed. This review is hopefully to provide some useful guidance for the development of high-performance castables.
Keywords: castable; hydratable alumina; hydration behavior; microstructure
