Abstract

The current jacking system for the hydraulic electric furnace electrode in Jilin Ferroalloy Factory is adopted the hand control in electrode jacking plan, against this situation, a structure, which can adapt the linear stepping motor to control the digital valve for adjusting the location of the hydraulic system has been raised, and the current system would realize automatic control to the electrode jacking by this way, at the same time, and by Fuzzy-PID control method the linear stepping motor would be controlled to obtain precise positioning in control. The hydraulic system controlled by digital valve have been described and analyzed in jacking feasibility and stability. What´s more, it is inspected and verified that the adjustment of this system has high precision and quick response.
