Abstract

In this study, the penetration of molten aluminum to alumina-silicate refractory brick with high alumina and cement additive was observed. Brick samples with high alumina content were tempered at 825 °C and fired up to 1350 °C. Corrosion test was applied to sintered samples in order to examine the effects of the molten aluminum containing 5 wt.-% magnesium which is thought to have a high aggression. The achieved structural characteristics were compared with similar types of commercial bricks in order to examine its industrial potential. Physical, analytical, and micro-structural tests were applied and the results are reported.

Kurzfassung

In der diesem Beitrag zugrunde liegenden Studie wurde die Penetration von geschmolzenem Aluminium in Aluminium-Silikat-basierten feuerfesten Ziegeln mit hohen Aluminium- und Zementzugaben beobachtet. Die Schamottsteinproben mit hohem Aluminiumgehalt wurden bei 825 °C geglüht und bis auf 1350 °C erhitzt. Es wurde ein Korrosionsversuch mit den gesinterten Proben durchgeführt, um die Wirkungen des geschmolzenen mit 5 Gew.-% Magnesium beinhaltenden Aluminiums zu untersuchen, wobei angenommen wurde, dass dieses eine hohe Aggression aufweist. Die erreichten strukturellen Charakteristika wurden mit ähnlichen Typen kommerzieller Ziegel verglichen, um das industrielle Potential zu untersuchen. Es wurden physikalische, analytische und mirkostrukturelle Untersuchungen gemacht und über die Ergebnisse berichtet.
