MASS-TRANSFER MODEL ANALYSIS OF ESR PROCESS ON INDUSTRIAL UNIT

The new model developed by the authors is used to predict and simulate the ingot and slag composition during the ESR process of Cr-Mo-V turbine rotor steel on an industrial unit. The results are shown to be in excellent agreement with those of practical process in an ingot diameter of 2300mm, also to agree with observations on Ca and Al deoxidation, and the model may be expected to offer a practical basis for the control of Composition during the ESR.
