SOFTWARE DEVELOPMENT FOR RESEARCH OF THE HEAT MODE OF THE BARREL OF THE TOP CONVERTER LANCE

Abstract

The main reason for the insufficient stability of the top converter lance is poor cooling, which, in turn, can cause burnouts of the head and (or) the external pipe of the device. In this regard, studies of the thermal mode of the outer pipe of the upper converter lance during its operation are of considerable interest.Conducting full-scale or laboratory studies aimed at studying these problems is too complicated and practically impossible. It is advisable to solve this problem numerically using computer simulation.To conduct a significant number of numerical experiments to study the thermal mode of the upper lance trunk, the development of appropriate software becomes relevant.The main goal of the work is to create a software application for computer simulation of the thermal mode of the barrel of the upper converter lance during its operation. The basis of the created application is the corresponding mathematical model.As a result of work using modern technologies of Microsoft Visual Studio 2019 and approaches to software development, a software application was created in C # language, with which you can perform computer simulation of the thermal regime of the barrel of the upper converter lance during the oxygen-converter steel production process.Original design, intuitive user interface developed; software application testing using specific application examples; The test calculation and simulation of the thermal mode of the upper converter lance for typical production conditions were performed.The developed application can be used in research, modernization and effective development of a cooling system for upper converter lance of various designs. Using the results received, it became possible to increase the stability of the upper converter lance thanks to a preliminary calculation of their thermal mode, forecasting and timely warning of emergency situations during oxygen blowing of metal.
