Blast furnace furnace thermal control control equipment

摘要

PURPOSE:To control furnace heat in a blast furnace at high accuracy corresponding to the actual furnace condition by executing the prescribed inference as artificial intelligence from processed data prepared from the data and the knowledge data based on the experiences in the blast furnace. CONSTITUTION:The various data in the blast furnace 1 are stored into filing means 14 from a scanner 11 through collecting function 12. These data are operated with operating means 16 to store the obtd. processed data into a common data buffer 24. Based on these processed data and the knowledge bases from the knowledge base storing means 22, the furnace heat level and the furnace heat shifting in the blast furnace 1 are inferred and operated with an inference engine 26, to decide an action rate to the blast furnace 1. The above knowledge bases contain various judging knowledge base, correcting knowledge base, synthetic judging knowledge base and rules deciding the action rates. The above decided action rate is outputted into a digital measuring instrument 32 from blast furnace heat control device 10 through output means 18 and the furnace heat control in the blast furnace is executed under considering the actual operational result.
