COMPUTER SYSTEMS OF THERMAL ANALYSIS FOR MONITORING OF FOUNDRY AND METALLURGICAL PROCESSES

Abstract

A computer system for monitoring thermal processes occurring in foundries and metallurgical plants is described. Thermal processes are considered in detail as the main processes occurring in the casting process. Two methods of metal quality control by the method of thermal analysis of casting on the lost foam model are considered. The article describes the characteristics of thermal analysis and thermal processes. Methods of quality control of cast iron by filling the sample with liquid metal and performing computer thermal analysis are presented. Methods of thermal analysis of metal, as well as methods of optimization of cast structures based on the results of computer comparison of data from thermal analysis of different parts or walls of the casting, which determines the mechanical or operational characteristics of metal in these parts or walls of the casting as data for optimizing cast structures data. A brief overview of software for monitoring thermal processes is given. The block diagram of the computer equipment intended for modeling of thermal processes, the description of problems which it solves, and also its short description is given. Software has been developed to support the decisions of the foundry, which will automate certain stages of the casting process, improve the quality of metal products. This can be seen as the first steps towards creating artificial intelligence systems to control foundry and metallurgical processes in terms of metal quality, optimization of charge and smelting technology, optimization of casting design based on thermal analysis data obtained from many casting points. Simultaneously, digital records, building a database of thermal analysis and computer analysis of this database, as an element of digitization of foundry and metallurgical technology, allows you to adjust the technology in the course of online smelting, which increases productivity and quality of metal products.
