The aim of the calculation presented in this report is to get more data about the specific calorimetric effect, e.g. the cathode cooling or heating per electron, of thermo-field electron emission from metals over wide ranges of work functions, e q = 2.0 to 4.5 e x electron temperatures T, = 2000 to 4500 K, and electric field strengths F = 1 0 ' to 1 0 ' Vcm". For metals such as Cu, Nb, MO, and W, most commonly used in vacuum electron discharge devices, the temperature range has been further expanded up to 500 to 10000 K.

Need of a research of processes of hashing of liquid metal fusion for receiving homogeneous alloys is proved in this work. The mathematical model of processes of electromagnetic hashing of the fusions received the arc furnace is given. Statement of a special experiment for check of the offered model is considered. Results of calculations and the made experiments on the small-sized arc furnace are given. In the conclusion good coincidence of the offered theory and an experiment is emphasized and recommendations for improvement of the available processing equipment are made.
