Silicon-Carbide Degassing Rotors Reduce Oxidation, Lower Replacement Cost

摘要

MORGAN ADVANCED MATERIALS launched its new generation of degassing rotors for secondary aluminum processing applications, based on its experience with materials science and metalcasting products. The first one-piece degassing rotor in silicon-carbide for molten aluminum processing reportedly are a cost-effective and high-performance alternative to the graphite material traditionally used for this task. The presence of gas (typically hydrogen) and other particles within gravity or sand castings will result in bubbles that may severely compromise both appearance and performance (overall strength and density) of the finished products. This makes effective degassing essential to casting process quality.
