Modelling Annealing Lehr Performance

When having to deal with variations in the volume or type of production, the ability to predict how various parts of the process will react to the changes is essential. This article looks at the effect on annealing lehr performance on the float line when the ribbon width and the tonnage throughput are changed. A computer model is used to predict the outcome and also to look at the efect of changing the direction of airflow in the first zone of the lehr.
