Abstract
The article describes the method of control of VAR furnace by program step. The papers [1, 2] describe the model of voltage control for VAR furnace. However, furnace controller generates huge static error, and using program step can solve this problem. The program step calculates movement of consumable electrode with constant melt rate and electrode gap in right parameters. The control with program step helps to remelt ideal consumable electrodes without feedbacks in VAR furnace. Situation changes when we try to remelt a nonideal consumable electrode using only program step because it is very diffi cult to get right parameters. This problem can be solved by using the voltage feedback with program step. The authors have got the models of ideal and nonideal consumable electrodes in conditions of Matlab.
