Wear mechanism of a novel AlSiMgAl2O4Al2O3

2019/6/15The phases of the Al Si MgAl 2 O 4 Al 2 O 3 composite brick after use in the RH degasser show a functional gradient distribution with distance. In particular, the major phases in the erosion zone are Al 15.44 Fe 6.16 Mg 2.32 O 32.00 (Mg-hercynite spinel solid solution), α-Al 2 O 3, and a minor amount of Al 3 Fe 5 O 12 and SiO 2 are also detected.

Graphite rotor, impeller shaft – Sialon Ceramics

Introducing the new Sialon alternative for graphite rotor impeller shaft to be used for degassing in molten auminium. Graphite rotors, impellers and shafts are widely used for dispersing hydrogen of Aluminium. During aluminum and aluminum alloy smelting, hydrogen produced by chemical action with steam diffuse in molten aluminum, which will cause inner structural defect to aluminum products.
