摘要：An automatic control system of the electrode's position during whole process of steel-making based on real-time control is presented in this paper, which is adapted for LF steel-making stove. The voltage between electrode and molten steel is measured accurately, which is used to calculate the accurate distance of the electrode and molten steel, during whole process of steel-making. The original position is memorized when the anodes descend to the molten steel, and the electrodes move upwards suitably when the cathode begin to make electric arc that achieves the best control distance. The whole process of steel-making would complete and the molten steel would purify. The problem of carburet of molten steel would guarantee the quality of steel production by using the control system.
