Detection method of gas flow distribution of burden surface based on two-stage information fusion

The situation of gas flow distribution in burden surface ensures to a certain degree whether the blast furnace could be running in a way of high efficiency and low consumption, and then influences the economic benefits of the whole steel enterprises. Focusing on the difficulty of directly detecting the gas flow distribution in burden surface, a method of that distribution is designed in this paper by employing the method of hierarchical information fusion. Firstly, the multi-source information is deal with spatial and time registration technology. Secondly, the model of burden distribution and burden surface temperature profile are designed by means of data level fusion respectively. Then, based on the two models, the distribution of gas flow in burden surface is obtained with the fuzzy decision level information fusion algorithm. Finally, according to the field data simulation, the validity of the modeling method employed in this paper is verified, the gas flow distribution in burden surface could be accurately reflected, and the operation of blast furnace might be well guided.
