Summary:In order to obtain the effect of taper heating in extrusion, the temperature distribution with the lapse of time was obtained in terms of billet, die and container, by applying the difference equation method to two typical examples, and calculating the heat generated in billet and heat transfer in billet, die and container during extrusion. Taper heating will not increase to a larger extent the temperature difference of products at the final stage of extrusion process, even though the billet temperature is decreased more than by uniform heating. However, taper heating is effective to decrease the product temperature and increase extrusion speed at the same time.
