Investigation on Al-Al₂O₃-MgO·Al₂O₃ Composites Refractory Performance for RH Degasser

Abstract:

The unfired Al-Al₂O₃-MgO﹒Al₂O₃ bricks were prepared with white fused corundum, fused spinel power and metallic aluminum powder. Effects of metallic aluminum powder content (mass%=0, 2%, 4%, 6%, 8%respectively) on normal temperature physical properties and microstructure were investigated. The result revealed that by adding aluminum powder the sample showed the characteristics of “plastic molding”. New nonmetallic reinforcing phase was generated at high temperature. It could help to improve the performance at both normal temperature and high temperature.
