Advantages include a control network, core network, management network, and a four-level cloud factory network, which are compatible and open. The system is equipped with in-depth defense measures that combine software and hardware to ensure safety. Simulations are performed based on real-time parameters and models, with recommended operating parameters and calculations of the actual position of the electrode working end based on the process and operating parameters of the submerged arc furnace. It features a multi-dimensional energy efficiency evaluation system that provides comprehensive evaluations of process value in real time and delivers timely operational suggestions. Additionally, a multi-dimensional equipment health model is implemented to predict key equipment failures and diagnose their causes.
