design of a rotor for aluminum degassing assisted by

Melt Treatment

SMARTT Degassing is a software module for FDU and MTS devices that predicts the best treatment practice based on ambient conditions, melt temperature, rotor design and alloy composition. The SMARTT software determines rotor speed, inert gas flow rate and treatment time and transfers this data to the degassing unit before treatment begins to ensure a constant quality level and reliable results.

Degassing Systems

Most rotary degassing systems available incorporate specially designed shafts, rotors, baffles, tooling and control systems to ensure consistent and efficient degassing operations. They are specifically designed for long-lasting, reliable operation in harsh molten aluminium environments.
