Designing Sheet Ingot Moulds to Produce Rectangular Ingots of the Desired Thickness and Width
Abstract
The design of moulds for casting rectangular sheet ingots has often been based on trial and error. To simplify fabrication, moulds have generally been designed using a series of flats to approximate the real mould contour required to produce a rectangular ingot.
The resulting ingots generally have a gull-winged contour on the rolling face.
This paper will demonstrate that a sinusoidal-type mould contour is required in order to cast perfectly flat sheet ingots.
In addition, an empirical model for calculating mould geometries is described. The model takes into account the alloy, casting speed, ingot width, ingot thickness and the width to thickness ratio when determining mould openings at any point along the mould.
The model has been verified through ingot and mould measurements and is predictive within certain limits.
