Abstract: Alumina-carbon refractory is a kind of carbon composite refractory made from alumina and carbon, adding additives such as Al, Si and SiC, and bonded with binders such as asphalt or resin. It is widely used in blast furnace ironmaking, hot metal pretreatment, steelmaking, continuous casting and other metallurgical processes. The composition of refractories is the basis for obtaining high quality properties. Sorting out and analyzing the effects of various components in refractories on properties can provide theoretical support and research guidance for the development of lowcost and high quality refractories. In this paper, the functions of carbon sources, binders and additives in alumina-carbon refractories and their effects on the properties of alumina-carbon refractories were summarized, and the potential research directions were prospected.

Key words: alumina-carbon refractory, physicochemical property, carbon source, binder, additive
