Abstract
In order to explore the possibility of reducing energy costs and defects, as well as to increase the quality of melted ingots, the authors held the model of voltage control in vacuum arc furnace. The control objective was determined, which is to maintain the integral of the difference between the desired and the actual voltage in the range, not exceeding the value predetermined by technologists. The basis of the proposed model of voltage control in the vacuum arc furnace was based on the voltage equations of: furnace, electrode gap, displacement of rod-electrode to electrode, the DC motor and the drops weight. The formation of droplets was analyzed. The schedule and system of equations describing the gradual formation of droplets was proposed.
