Method of online real-time prediction of mechanical properties based on hot-rolled coil production process

Abstract

The invention provides an on-line real-time mechanical property prediction method based on hot rolled steel coil production processes, and belongs to the technical field of metallurgical industry manufacturing and informationizing. A prediction model is built for mechanical properties of a hot rolled steel coil on the basis of historical true technological parameters, and on-line single prediction and curve prediction on the mechanical properties of the steel coil are achieved through the prediction model. On one hand, massive historical technological parameters are analyzed and summarized to deduct the stable and efficient property prediction model. On the other hand, management and property prediction are conducted on the model, real-time on-line mechanical property prediction is conducted on the produced steel coil, single prediction data is uploaded to an MES three-stage system, and curve prediction data is uploaded to a quality judgment system. Accordingly, property prediction and judgment full automation are achieved, the property examination and labor cost is reduced, and the enterprise production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of manufacturing and information technology in the metallurgical industry, and in particular relates to a method for online and real-time prediction of mechanical properties based on the production process of hot-rolled steel coils. Background technique [0002] The ability of metal materials to resist damage under load is called mechanical properties (or mechanical properties). The performance of metal materials determines its scope of use and service life. The mechanical properties of metal materials are the main basis for the design and material selection of parts. The nature of the applied load is different (such as tension, compression, torsion, impact, cycle Load, etc.), the mechanical properties required for metal materials will also be different. Mechanical properties are a collection of commonly used indicators of metal materials, which mainly include yield, tensile strength, elongation, grain size...

Problems solved by technology

[0004] 1. The inspection process involves multiple processes such as unbooking, sampling, sample delivery, inspection, and return performance, and the inspection cycle is long;

[0005] 2. Need to consume a certain amount of human, material and financial costs;

[0006] 3. The mechanical performance inspection is only for the partial inspection of the sample coils, not the whole coil inspection and all coil inspections, which makes the inspection results partial;

[0007] 4. The performance test results do not display the analysis platform;

[0008] 5. Waste of surplus material
