Patented combination – induction and gas for inline heating

Description

Optimum utilization of space and perfect billet heating
Together with extrutec IAS has developed a patented inline heating system for extrusion plants. In doing so we have succeeded in providing a compact system solution that can be integrated into existing press lines, even if there are real space limitations. The inline system comprises a gas furnace with various heating zones and a direct, downstream multi-zone induction furnace.
Rapid return on investment
A gas furnace alone is no longer sufficient to meet today's demands with regard to the temperature control of modern aluminium extrusion presses. The innovative combination of the inline system featuring a gas and induction furnace ensures optimum energy utilization with extremely precise temperature control. Any number of axial temperature gradients (tapers) is possible. The result is a considerably more productive extrusion process with consistently high extruded product quality. What's more, any unwanted temperature distribution within the workpiece - that could lead to process faults - is avoided. These advantages mean plant owners can achieve a rapid return on their investment.
Continuous inline production
With our patented inline heating system the bar is first heated in a gas furnace. It then reaches the desired final temperature in the multi-zone induction furnace, whereby the precise temperature profile of the billet to be cut off is taken into consideration. The concept is based on TEM-PRO Heater® technology from IAS. Before the extrusion process the bar is cut to the required billet length using a saw or shear.
