Control of Secondary Cooling in Dynamic Casting Modes
The aim of this paper is to study the influence of the secondary cooling control method on the temperature field of a continuous ingot under dynamic casting conditions. The main tasks were the development and implementation of a mathematical model of ingot cooling, as well as the identification of a control method that is used in a real industrial plant. As a research hypothesis, this paper considers the change in the surface temperature of a continuous ingot during the transition process. Significant temperature fluctuations negatively affect the condition of the metal, increasing its tendency to defects. Methods for evaluating methods for controlling secondary cooling are based on the results of mathematical modeling. The novelty of the research lies in the application of a new approach to mathematical modeling of changes in the thermal state of the metal under dynamic casting conditions, as well as a method for evaluating control methods based on temperature fluctuations along the entire length of the ingot during the transition process.
