Method for predicting evolvement and performances of structure of strip steels in hot rolled proces

Abstract

A method for predicting the structure variation and properties of band steel in hot rolling procedure features that its system is composed of the preprocessing module for reading the technological parameters needed by hot rolling from database, the heating module, rolling module, cooling phase-change module and mechanical performance module for simulating the hot rolling procedure and predicting the final structure performance, and the post-precessing module for displaying the final result.

Description

technical field

[0001] The invention relates to strip steel rolling technology, in particular to a method for structure evolution and performance prediction of strip steel during hot rolling. Background technique

[0002] In the prior art, strip steel needs to be tested (tensile strength, yield strength and elongation) before it can be put on the market after rolling. It is said that it is rolled at the speed of rolling one coil in a few minutes, so the amount of testing after production is very large, which is a waste of manpower and material resources, and because there are human factors in the test, it will more or less affect the test. precision. It is undoubtedly encouraging if the performance of the product can be predicted by means of computer simulation and the degree of exemption from inspection can be achieved. In order to achieve this goal, it is necessary to understand the change process of various parameters in the rolling and cooling process, and it is imposs...

Embodiment 1

[0024] As shown in Figure 1, the present invention takes ordinary carbon steel as the research object, and establishes a systematic physical metallurgical model. The post-processing consists of six modules. The function of the pre-processing module is to read the process parameters required for the hot rolling process from the database and provide initial conditions for the subsequent process; the heating module, rolling module, cooling phase change module and mechanical properties The module is to complete the dynamic simulation of each metallurgical physical quantity in the hot rolling process, and predict the final structure and performance of the strip; the function of the post-processing module is to complete the display and output of the simulation results of the hot rolling process; the details are as follows:

[0025] As shown in Figure 2, the specific process of the pretreatment module is: first read the production process parameters from the database, such as: the ste...
