BF iron-making is a complex multi variable system with a large number of sensors on it

due to the operational parameters are set by BF masters with their experience

relationship between comprehensive status indicators and various operating parameters is ignored

thus making consumption of resources are often in a‘blind’state. So the operational parameters should be optimized to realize reasonable utilization of resources and smooth operation of BF. The operational parameters in the process of BF iron-making can be optimized by matching similar operational patterns. Considering the low speed and precision of pattern matching process caused by huge superior operational patterns library

a multi-hierarchy matching strategy is proposed

this can determine the optimal operational pattern under the condition of the working status in a large number of industrial datas

thus can save energy

improve efficiency and increase benefit in the process of BF iron-making.
