Embodiment Construction

[0031] As far as the thermal simulation test of ultra-fine grain steel is concerned, its input space includes: chemical composition of test steel, deformation temperature, deformation amount, deformation pass, deformation rate, interval time, holding time, cooling conditions and other ten parameters; The output space is mainly the grain size and percentage content of ultrafine-grained ferrite and the corresponding mechanical properties. The samples for training the network are taken from the Gleeble-2000 thermal simulation test data of low-carbon microalloy steel. 0.8, P: 0.008-0.012, S: 0.005-0.008, V: 0.02-0.13, Nb: 0.02-0.13, N: 0.003-0.008. When the development time is limited and the process data is limited, the genetic neural network model of the application module is used to analyze various factors. After entering the main interface of the system's genetic neural network, select the submenu of "Build Genetic Neural Network" under "Application Module", and the "Build Ge...

Abstract

The invention relates to an iron thermal analog test material quantity control method in the field of iron researching technology. It adopts tetrahedral prototype based on element, art, organization and capability and adopts modular structure idea to establish intelligent system which has the following modules: a front handling module, a phase-changing module, an organization capacity module and an applied nodule, wherein the front handling module reads the test parameter from database needed by thermal analog test course to provide an initial condition for the subsequent course; the phase-changing module and the organization capacity module is the dynamic analog of each physical metallurgy module of the thermal analog art; the applied module looks for the best value between the network connecting authority and the network structure by establishing the neurotransmission network module to forecast the organization and the capacity of the thermal analog test.

Description

technical field [0001] The invention relates to the technical field of research and development of steel grades, in particular to a material control method for steel grade thermal simulation tests. Background technique [0002] In recent years, the research and development of a new generation of steel materials characterized by ultrafine grains has become an important direction for the development of steel materials in the world today. In the necessary stage of new steel research and development—thermal simulation test, it is necessary to carry out a large number of thermal simulation deformation processes and microscopic analysis of corresponding samples of steel samples with multiple components to explore the optimal composition and composition of new steel types. The optimum value of process parameters. However, the research and development of ultra-fine-grained steel is still limited to the stage of experimental observation and general theoretical discussion, which requ...
