Embodiment 1
[0042] A method for calculating the optimal proportion of iron ore sintering, the calculation process is as follows figure 1 As shown in the figure, under the determined application environment, according to its sintering production requirements, gradually increase the proportion of a certain iron ore, and determine a group of ore blending plans with low ore blending cost and excellent sintering index. Carry out a comprehensive evaluation of the proportioned ore blending plan, and determine the proportion of iron ore with the highest technical and economic comprehensive evaluation index in this application environment and the corresponding ore blending plan.
[0043] The sintering process parameters and product quality index model structure are as follows: figure 2 As shown, in the model, a represents the Lagrange multiplier; b represents the deviation, which are the optimal solutions obtained by minimizing the error between the training sample and the optimal classification...
