Intelligent automation model for BF ironmaking process

To realize intelligent automatic control of BF ironmaking process, automation groundwork and transmission of information by net were summarized, and some mathematical models were established based on intelligent control theory, including BF ironmaking process multi-object program model, intelligent prediction model and intelligent control partial differential equation of temperature in BF. After the expert system developed on those models used on No.1 BF at Laiwu Iron and Steel Group Co., the BF ironmaking process was optimized, the temperature in BF was precisely predicted online, process control parameters self-adjusted to make the temperature in BF trend to the best. The BF runs smoothly.
