Japan, March 5 -- NIPPON STEEL CORP has got intellectual property rights for 'QUALITY PREDICTION METHOD OF SINTERED ORE AND YIELD PREDICTION METHOD OF SINTERED ORE.' Other related details are as follows:
Application Number: JP,2022-117948
Category (FI): C22B1/16@P
Stage: PROBLEM TO BE SOLVED: To predict quality and yield of sintered ore accurately more than ever.SOLUTION: A quality prediction method of sintered ore is provided, the method comprises: a variable selecting step for selecting input variables in which a coefficient imparted to each of input variables has a predetermined value or more by performing Lasso regression with at least the blending specifications for each raw material brand during sinter production, firing specifications, heat source blending ratio, quicklime blending ratio, and component values of sintered ore as input variables, and with the quality value of sintered ore as an output variable; a statistical model learning step for learning a statistical model with the variables selected in the variable selecting step as input variables and the quality value of the sintered ore as an output variable; and a quality prediction step for predicting the quality value of the sintered ore from the prediction target data of the variables selected in the variable selecting step using the learned statistical model.SELECTED DRAWING: Figure 2 (Grant)
