System and method suitable for quality control of reverse solidification technique

Abstract

The invention discloses a system and a method suitable for quality control in an inverse solidification process. The system mainly comprises a data acquisition module, a visualized display module, and an adaptive expert system, wherein the adaptive expert system comprises a defect diagnostic reasoning module, a processing parameter reasoning module, an adaptive rule base correcting module, and a knowledge base. The processing parameter reasoning module reasons and provides optimized processing parameters before production, the data acquisition module and the visualized display module carry out data acquisition and visualized animation display on a detected production process, the defect diagnostic reasoning module analyzes performance and defects of products, and the adaptive rule base correcting module extracts defect analysis result of the products and the processing parameters re-correct rule to be fed back and applied to the processing parameter reasoning module so as to carry out a new production process. The system and the method can remarkably improve combination quality of a motherboard solidification layer in the inverse solidification process, accumulate processing experience, reduce defect, and save experiment expense.

Description

Technical field [0001] The invention relates to the fields of casting production, intelligent control and computer information processing, in particular to a system and method suitable for quality control of inverse solidification process. Background technique [0002] The inverse solidification process is a new type of thin strip continuous casting process first researched and developed by Germany Mannesmann-Demark in 1989. There are few reports in foreign countries, and laboratory research has just begun in China. It was listed as my country in 1996. Key projects funded by the National Natural Science Foundation of China, experimental research has achieved certain results. The reverse solidification casting method is to pass the mother strip through the molten steel to solidify the molten steel on the surface of the mother strip. Because the solidification direction is opposite to the traditional solidification direction, the solidification surface moves from the inside to the ...
