Embodiment 2

[0109] Embodiments of the present invention provide a method for evaluating the performance of a sintering production process based on fuzzy synthesis, comprising the following steps:

[0110] (1) Establish an evaluation factor set for optimizing the control layer, that is, collect historical data of sintering production to obtain original sample data and establish a sample database;

[0111] The historical data of sintering production is stored in the local database of the industrial computer in the operating room in the form of daily reports. According to the data in the daily reports, the historical data of ignition temperature and sintering end position for one month are collected to form the original sample data. The evaluation period is set to 10 days , the data average value of every half hour is used as a set of data, and a total of 480 sets of evaluation data are obtained, and a sample database is established with these data; and the formulas (1) to (6) of Embodiment 1...

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...
