Improvement of Blast Furnace Performance by Applying a High-Efficiency Expert System

摘要

The price and quality of iron ores have been varying frequently and dramatically worldwide for many years, bringing about great difficulties in blast firrnace operation. In order to help the operators to steer the furnace under this unfavorable condition, a new concept was proposed for developing a low-cost and high-efficiency expert system and applied to the development of the ES of a 3 200 m~3 blast furnace in Southern China. This system has been working trouble-free since September 2012. Due to its implementation, productivity increased by 0.247 THM/m~3-d and comprehensive coke rate decreased by 21 kg/THM.
