Comparison of the Thermo-Mechanical Conditions in an Industrial Sized Hot Aluminium Extrusion Process in Relation to those in Corresponding Small Sized Laboratory Processes

Abstract:

It is common to use scaled down laboratory extrusion processes in order to physicalmodel the industrial big-sized aluminum profile extrusion process. In industrial extrusion use ofbillets with a diameter size of ~210 mm, or above, is common. In the scaled-down laboratoryprocesses half this size is often used, and in mini-extrusion also 1/7th of this size. An investigationhas been undertaken in order to study what are the thermo-mechanical conditions in extrusionprocesses of such different sizes of processes, and to what extent a small-sized process is able tophysical model accurately the conditions in an industrial large sized process.
