Assessing the shape of the viscoplastic iron-ore zone in a blast furnace

A mathematical model permits assessment of the position and shape of the viscoplastic iron-ore zone (cohesion zone) in a blast furnace and identification of a rational configuration for this zone on the basis of readily available information regarding the blast furnace in the baseline period. The model also permits the solution of design problems with variation in the furnace parameters. Modeling results are outlined for the baseline and design periods. © 2013 Allerton Press, Inc

Simulation of heat-transfer processes and assessment of the viscoplastic parameters of iron ore in blast furnaces

Stages in the development of an information and simulation system for assessing the position and shape of the viscoplastic iron-ore zone (the cohesion zone) in the blast furnace are outlined. This system also permits diagnostics of the zone's optimal configuration on the basis of available operational information for the furnace in the baseline period. In addition, the system proves useful during the design period, with variation in the smelting parameters. The capabilities of the corresponding software are discussed, and its use in blast-furnace control at OAO Magnitogorskii Metallurgicheskii Kombinat is demonstrated. © 2013 Allerton Press, Inc

Modern methodology and computer technologies for creating software of model systems supporting decision-making in metallurgy (On the example of blast-furnace production)

Experience shows that the creation and successful introduction of modern automated information systems into the practice of metallurgical enterprises largely depends on the technologies used to develop and to select the tools for their software implementation. The article briefly reflects the main technologies and software used to create software for information modeling systems to solve technological problems in metallurgy. The basis is the use of a flexible development methodology – the Agile method, which focuses on the use of iterative develop- ment, the dynamic formation of user requirements, and the provision of their implementation as a result of constant interaction within working groups consisting of specialists of various profiles (users, analysts, programmers, testers). Iteration is a relatively short development time (usually a month), after which the users are provided with the next tested version of the software product with new functional properties. The list of realized functional properties is priority for users and is formed from the general list of requirements before the beginning of each iteration. During each iteration, the following processes are sequentially performed: checking the correctness of the calculation algorithm (if necessary, entering new calculated indicators); functional modeling of the system; improvement of the structure of the subsystem; conceptual modeling of the database, generation of the database model; loading test data into the database; creation of functional diagrams of mathematical library; implementation of client software subsystems; testing and debugging of software; development of reference documentation. Managing individual tasks and monitoring the progress of their implementation in the course of collective software development are carried out on the basis of the Atlassian JIRA system. Code storage and versioning of software are performed in a remote repository on the Atlasian Bitbucket platform. The use of modern technologies, tools and techniques for developing software products makes it possible to create functional, reliable, easy-to-use, followed, integrated systems with minimal risks and at acceptable times. © 2017, National University of Science and Technology MISIS.
