In-line heat treatmet of forged parts

Use of the residual heat of parts for a more efficient annealing heat treatment.

Heat treatment is a key stage in a wide range of forged components, which is mainly carried out in batch furnaces. However, in the conventional discontinuous heat treatment, the process of letting the forged parts cool down to room temperature and then raising their temperature again, maintaining it until the desired properties are obtained, involves significant energy and time consumption.

In order to improve the competitiveness of this process, in terms of costs, time and sustainability, AZTERLAN has developed an in-line annealing heat treatment method in which the forged parts are introduced into the furnace while they are still hot.

Can I apply this heat treatment
in my plant or process?

This innovative heat treatment for forged parts is based on a controlled cooling (already in the furnace) of the pieces and the application of an isothermal treatment (maintenance of the temperature in the furnace). This is a solution applicable to most forges whose facilities allow the installation of an anodizing furnace.

Prior to its implementation, it is necessary to carry out a study based on the unique characteristics of the geometry of the part in order to determine the optimal settings of the treatment to ensure the objective mechanical properties of the final components:

We add value through optimization

“Solid state forming technologies gather a diverse group manufacturing means, materials and sectors with very different characteristics. However, they face common challenges associated with the incorporation of new materials, demanding production rates and increasing requests for the products they manufacture.

Developing components with advanced features, improving the useful life of manufacturing tools and addressing new markets and industrial applications are some of the areas through which we add value to the companies that design, manufacture and apply these components.”
