In the second part of the work the authors present some results of computer simulation of the melt electric current treatment (ECT) process performed on the basis of differential equations by the finite element method using COMSOL software package. From experience of numerical experiments shortcomings of such models have been revealed that limit possibility of their use in algorithmic procedures, which are embedded in the integrated three-componentin formation system (ITIS), described in the first part. The physically adequate computer models based on the integral representation of the ECT process equations, developed by the authors, which are adapted to the specific problems of control of melt treatment modes, have been relieved of these drawbacks.  The results of verification of the developed models by analytical samples are presented, as well as examples of solving problems that simulate ECT modes. The obtained results create the basis for transition to implementing of the entire concept of automation of ECT modes control system.
