Disign And Application Of Performance Prediction System For Hot Rolled Coil

With the improvement of fine steel production requirements, Product quality control requirements are also increasing, Especially the mechanical properties of the steel products is always the important quality indicators, Due to it is difficult to detect the mechanical properties of the product online, it becomes the iron and steel production problems,which is to be sloved, so, Online prediction of the mechanical properties of hot rolled coil has important theoretical and practical significance.This research is based on the mechanical properties forecast of the rolling integration of high-class hot-rolled planes, which were produced in Shougang Qian’an steel. Firstly, hot rolled coil mechanical properties of forecasting techniques for the study and application are described, Understanding the parameters and its effects between the mechanical properties and relationships, And to determine the mechanical properties prediction model of input and output structure. According to the variables characteristics of input and output, This article use BP neural network to establish forecast model of mechanical properties, In order to ensure the scientific and effective network model,Conducted in-depth study and research on the BP neural network theory and characteristics, Select the appropriate improved algorithm, Build a three-performance network model, After the number of nodes to be determined, Complete the design of the model to predict properties, Collect the actual production data, The data necessary to deal with outliers excluded, the standardized conversion, By using effective data plate rolling roll performance forecast model simulation experiments, The results verify the validity of the method. Based on this, Combined with C#, MATLAB, ORACLE development tools, Comprehensive utilization of mixed programming, expression parser MATLAB file parsing^XML serialization and deserialization technology and method, Combined with process requirements, Hot rolled coil performance forecasting system developed. Hot rolling plate roll mechanics performance prediction system through the actual application, The effective implementation of the hot rolled coil on-line performance prediction, And to achieve forecast accuracy requirements.
