Abstract

En el proceso de enfriamiento primario durante la colada continua de aceros sucede una serie de transformaciones físicas que inciden directamente en la calidad final del producto. Los modelos matemáticos que explican este fenómeno no pueden ser tratados indistintamente para una instalación u otra debido a las disímiles variables implicadas en el proceso. En esta investigación se obtuvo un modelo físico- estadístico mediante regresiones múltiples sucesivas para el caudal necesario de agua en máquinas de colada continua de aceros con cristalizador curvo. Para el modelado se tuvo en cuenta las variables de operación del enfriamiento en cristalizadores curvos así como la validación estadística en
condiciones de explotación en tiempo real. El modelo obtenido permitió estimar el comportamiento de las variables de control del proceso con suficiente precisión.

Palabras claves: enfriamiento, solidificación, colada continua, modelado, aceración.

Abstract

In the process of primary cooling in the continuous casting of Steel there are physical transformations that affect directly the quality of the final product. The mathematical models that explain this phenomenon cannot be applied to different installations because the variables involved in the process are different. In
this research, a physical-statistical model was obtained through multiple and successive regression for the flow of water which is necessary in this complex process. For the modeling the variables of operations in the cured cooling systems were taken into account as well as the statistical validation in conditions of
exploitation in real time. The model permitted to predict the behavior of the variables with sufficient precision.

Key words: cooling, solidifications, continuous casting, modeling, steelmaking.
