Abstract
A study of a mold narrow plate was performed at IAS in order to assess the plate condition after its life. A finite element model of steady heat conduction in the mold narrow face has been developed using ANSYS. Attention was focused on the hot-face temperature distribution, including the corner temperature and the difference between the maximum and minimum temperatures across the hot face. Temperature distribution in the narrow face of the mold was calculated, and alternatives to optimize the water slot design by altering the geometry in order to minimize both corner temperature, and temperature variation across the hot face, were analyzed. According to results the existing narrow face design does not produce excessive temperatures anywhere in the mold. However, a gradient exists across the hotface. In addition, an accurate equation was developed to predict corner temperature as a function of hot face heat flux and water slot geometry. Several other water slot geometry redesigns (1-5) were investigated which further improved potential hot face temperature uniformity, at the expense of increasing complexity of the water slot redesign. The predictions of the model are in agreement with observations made in a previous post mortem study carried out at IAS on a narrow plate.
