THE PROCESSING OF EXPERIMENTAL DATA FROM THE PHYSICAL MODEL OF A FDU REFINING UNIT
Original language description
The present paper describes a method for processing experimental data obtained on a physical model of a refining unit, the Foundry Degassing Unit (FDU). For different refining gas flow rates and rotor rotation speeds of the FDU, the concentration of oxygen removed was measured depending on time. A large number of experiments were carried out with different rotor types and under different conditions. After examining the character of the data obtained, a method was proposed to evaluate the performance of different rotor types in degassing at a given gas flow rate at different rotor speeds. This method is based on interpolating several degassing curves in such a way that the resulting characteristic can be expressed by a single parameter. This final parameter then allows the degassing efficiency (refining capacity) to be quantified. In this unique way, the degassing efficiency of different rotor types can then be objectively compared. Furthermore, the parameter thus obtained can be used to determine the expected time at which the desired decrease in the concentration of undesirable gas in the bath will occur. Attention is also paid to the possible deviation that occurs when a large amount of experimental data is reduced to a single parameter by the described approximation.
