Embodiment Construction

[0041] figure 1 Schematic diagram showing how the structure optimizer works in alloy cost optimization. The calculation program for optimizing the structure, designated below as structure optimizer 1 , obtains target values ​​2 for the chemical composition and target values ​​3 for the operating parameters of the target process. The nominal values ​​2, 3 together give the so-called steel profile, which is based on experience and contains all the information required for the production of the respective task. The material properties of the steel produced can be influenced by the operating parameters of the plant, including process temperature and pressure and, if appropriate, their time derivatives. A mathematical model is implemented in the structure optimizer 1 which simulates the material properties and determines the changes in the microstructure of the steel for each production step. The structure optimizer 1 can also work with the method of neural network. As a result,...

Abstract

The invention relates to a method for controlling an installation for producing steel having specific material properties, which depend on the structure and which can be influenced by operating parameters of the installation. Said operating parameters are determined by a computing program for structure optimization, whereby the set values of the chemical composition of the steel are simultaneously determined by the computing program for structure optimization.

Description

technical field [0001] The invention relates to a method and a device for controlling a plant for the production of steel having special material properties which are dependent on the structure and which can be influenced by operating parameters of the plant determined by means of a calculation program for optimizing the structure. Background technique [0002] Steel must be produced with the material properties desired by the user. Important material properties of steel are, for example, tensile strength, elastic limit and elongation at break. These material properties are of crucial importance if the steel is intended for deep drawing (eg in the manufacture of car body panels or beverage cans). [0003] The material properties of steel are determined by its microstructure, which in turn is influenced and determined by the production procedures of the manufacturing process. [0004] It must be ensured during manufacture that the chemical composition of the steel correspon...
