Abstract

Abstract: The effects of two types of corundum-spinel micropowders (D and G) on the phase composition, bulk density, apparent porosity, mechanical properties, and slag resistance of corundum-spinel castable matrices were investigated. The results indicated that, with the same addition of corundum-spinel micropowders, in-situ spinel was formed in both groups after firing at 1 100 °C. After firing at 1 600 °C, spinel, corundum, and CA₆ existed in the two groups. Compared to the samples with powder D, those with powder G exhibited higher bulk density and lower apparent porosity after firing at 1 100 °C, but the cold modulus of rupture and compressive strength were lower. After firing at 1 600 °C, the cold modulus of rupture of the samples with powder G was higher, meanwhile there was minimal difference in the apparent porosity between the two groups. Both corundum-spinel micropowders showed good sintering activity, and the matrix samples exhibited excellent slag resistance. The corundum-spinel castable matrix with powder G showed better corrosion resistance compared to that with powder D.

Key words: corundum-spinel powder, sintering property, slag corrosion resistance
