| 英文摘要 |
| The burden profile plays an essential role in the decision-making for the blast furnace burden distribution.
This paper combines the radar measurement data with the mechanism analysis of burden distribution process based on the
developed new radar measurement. First, according to the Newtonian mechanics, this paper calculate the law of burden
particles motion from the flow control gate to the burden profile. Then, the burden profile model is established under the
volume constraint principle. Finally, the Gaussian process regression model is used to fuse the mechanism-based burden
profile model with the swing radar measurement data. The blast furnace burden profile model based on radar data and
mechanism model is established. The simulation results show that the proposed data-fusion method has better fitness to
the burden profile based on the radar measurement and mechanism model. Besides, the proposed method is helpful to the
stable operation, energy conservation and emission reduction for the blast furnace. |
