Performance evaluation method for sintering production process on basis of fuzzy synthesis

Abstract

The invention discloses a performance evaluation method for a sintering production process on basis of fuzzy synthesis. The performance evaluation method comprises the following steps: firstly, establishing two evaluation factor subsets aiming at an optimizing control layer, setting performance indexes and evaluation grades, calculating a fuzzy relation matrix of each subset, determining weights of all single factor performance indexes in the subsets by adopting an information entropy method, and establishing first-grade comprehensive evaluation models; secondly, considering the first-grade comprehensive evaluation models of the two subsets as two single factor performance indexes for evaluating the factor sets, establishing a total fuzzy relation matrix, determining weights of the two single factor performance indexes by adopting the information entropy method, and obtaining a comprehensive evaluation result of the optimizing control layer by the fuzzy synthesis; finally, evaluating the performance of a carbon effect optimizing layer. Therefore, optimal control of the optimizing control layer can be ensured, and further an evaluation result of the carbon effect optimizing layer becomes more reasonable.

Description

technical field [0001] The invention belongs to the technical field of performance evaluation of steel sintering production process, and in particular relates to a performance evaluation method of sintering production process based on fuzzy synthesis. Background technique [0002] The iron and steel industry is one of the pillar industries of the national economy, and the development of the iron and steel industry will also determine the development of our national economy. The sintering process is an important part of the ironmaking process, and the sinter produced by the process is the main raw material for blast furnace ironmaking. [0003] At present, the iron and steel production method adopted by world-renowned iron and steel enterprises is the belt-type draft sintering method. The main production process is to first fully mix the raw materials to obtain the mixture, and then spread the mixture on the trolley, and the mixture is in the ignition furnace. Point the surf...

However, since there is no certain standard to measure whether the optimization result of the carbon efficiency optimization layer of the hierarchical control system of the sintering process is the optimal result, each sub-control system of the optimization control layer operates around the wrong set value; seriously affecting the The quality of sintered ore, while wasting a lot of blast furnace gas, coke oven gas and coke powder, caused great economic losses
