Optimization of Quality of Continuously Cast Steel Slabs by Using Firefly Algorithm
Popis výsledku v původním jazyce
An ambition to increase both the productivity and the final product quality, in continuous casting process, led us to study new effective mathematical approaches. The quality of steel produced by continuous casting process is influenced by number of controlled factors as a casting speed or cooling rates. Appropriate setting of these factors is usually done by expert estimates and expensive experimental runs. This paper describes an algorithm for obtaining black-box type solution which maintains high production rate and high quality of products as well. The core of the algorithm is our original numerical model of 2D temperature field designed for real caster geometry. This mathematical model contains Fourier-Kirchhoff equation, including boundary conditions. The presence of phase and structural changes is modeled by an enthalpy computed from chemical composition of steel. The optimization part is performed by recently created heuristic method, so-called Firefly algorithm, where the prin
