Estimation of Steel Solidified Layer Thickness, for Continuous Casting Control Purposes

Abstract

An important goal in continuous casting automation process rest in establishing a proper casting speed being able to assure a compromise between machine productivity and solidified skin cracking protection on the mould level. Contextually, this paper presents new solutions regarding solidified layer thickness estimation for steel continuous casting. The new model starts from actual stadium analysis and propose a solution for analytical model modification, in such a way that the model to approximate solidification dynamics at different casting speeds, using both important parameters for continuous casting process, meaning casting speed and time. A series of results obtained using numeric simulation are presented as a validation for proposed solution.
