Intelligence Integrated AC Arc-Furnace Computer Control System

The computer control system, which is made up of high-quality periphery modules, focuses on industry control computer. It is made of double closed loops: the inner current loop and the outer temperature loop, and satisfies the electric arc furnace's (EAF's) temperature need and three phase current balance. Temperature loop adopts intelligent control technology, such as fuzzy control, neural network, expert control; and current loop introduces fuzzy expert coupling control of three phase current. Real-time adaptation to the changes of furnace conditions can increase productivity, reduce electric energy and electrode consumptions. It has better robustness and real-time in running system.
