Abstract: Electrode feeding system is one of the important systems of heavy electroslag remelting furnace. Eletrode feeding process of electroslag remelting furnace is drop process of cross arm. The cross arm of traditional electroslag furnace driven by ball screw has defects such as weak stiffness, low response etc. A large size hydraulic cylinder is utilized as the driver of the cross arm, and an electro-hydraulic proportional flow control valve is used to control the speed of the hydraulic cylinder. The mathematical model of the hydraulic control system is established and simulated. The simulation results show that the system theoretically works well.
