CASTING METHOD, MORE PARTICULARLY CONTINUOUS CASTING METHOD

摘要

Using a method for producing a material block or material section cast from liquid metal, wherein the temperature distribution prevailing inside the material block or material section is calculated by means of a temperature calculation model based on dynamic temperature control (Dynamic Solidification Control), wherein in one calculation step, the total enthalpy of the system formed by the material block or material section is determined and processed as an input variable within the temperature calculation model, and one or more output variable(s) of the temperature control model is/are used in the control and/or management process of the casting process, a solution is created that permits an improved calculation and prediction of the temperature distribution within a material section or material block cast from liquid metal during the setting process and more particularly, with a continuous casting method or process, permits an improved calculation and prediction of the setting length (position of the liquid phase tip) in the setting metal strip. This is achieved by calculating the total enthalpy from the total of the free molar enthalpies (Gibbs free energy) of all phases and/or phase fractions currently existing within the material block or material section.
