Sensitivity analysis of parameters affecting the thickness of the solidified layer in the continuous casting process of steels
A sensitivity analysis of the effect of the heat flow, casting temperature and casting rate in estimating the thickness of the solidified layer in the continuous casting was performed. Due of experimental difficulties for determining this thickness, a mathematical model of heat transfer during solid...

| description | A sensitivity analysis of the effect of the heat flow, casting temperature and casting rate in estimating the thickness of the solidified layer in the continuous casting was performed. Due of experimental difficulties for determining this thickness, a mathematical model of heat transfer during solidification, which consisted of a Lagrangian formulation in unstable state 2D was formulated. To simplify the solution, the concept of effective thermal conductivity was used in the liquid phase, so this phase was modeled as if it were a solid. With the alternating direction implicit method, the solution was obtained. The model was verified and validated by comparing the analytical solution and experimental results from the literature respectively. It was observed that with different casting temperatures it is possible obtain a solidified layer similar to the mold outlet. |

Debido a las dificultades experimentales para la determinación de este espesor, se formuló un modelo matemático de la transferencia de calor durante la solidificación, el cual consistió en una formulación Lagrangiana en 2D en estado inestable. Para simplificar la solución, se utilizó el concepto de conductividad térmica efectiva en la fase líquida, con lo que esta fase fue modelada como si se tratara de un sólido. La solución del modelo se llevó a cabo numéricamente con el método de diferencias finitas implícito de dirección alternante. El modelo fue verificado y validado mediante la comparación de una solución analítica y con resultados experimentales obtenidos de la literatura respectivamente. Se observó que a diferentes temperaturas de colada es posible obtener un espesor de la capa solidificada similar a la salida del molde.Universidad Tecnológica de Panamá2017-11-212017-12-12T14:16:19Z2017-12-12T14:16:19Zinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://revistas.utp.ac.pa/index.php/id-tecnologico/article/view/1709http://ridda2.utp.ac.pa/handle/123456789/33132219-67141680-8894I+D Tecnológico; Vol. 13, Núm. 2 (2017): Revista I+D Tecnológico; 5-14reponame:Repositorio Institucional de documento digitales de acceso abierto de la UTPinstname:Universidad Tecnológica de Panamáinstacron:U Tecnológica de Panamáspahttp://revistas.utp.ac.pa/index.php/id-tecnologico/article/view/1709/2445info:eu-repo/semantics/openAccesshttps://creativecommons.org/licenses/by-nc-sa/4.0/oai:ridda2.utp.ac.pa:123456789/33132019-12-06T14:50:30Z |
