Aim at the effect of the control method in traditional metallurgy furnace temperature is not good, a self-tuning fuzzy PID control method combining fuzzy control with PID control was proposed in this paper based on the analysis of the advantages and disadvantages of the PID control and fuzzy control method, and a concrete control algorithm was put forward and simulation experiment was finished. The simulation results show that the effect of the controller is good, and the control of system is fast and smoothly according to it.

Aiming at the status of the bottom automation system and upper management information system was not effectively integrated in iron and steel enterprise which leads to the delay of production data and the difficult of tracking production process, MES based on real-time database, in which production data is collected, analyzed and processed in real-time using real-time database technology, is researched and designed in this paper, it can optimize production planning and scheduling management level and greatly enhance the production efficiency and promote the core competitiveness of enterprise.
