Furnace Technology

With Ipsen's vacuum furnaces the advantages of vacuum heat-treatment can be used to the full. These include:

• optimum hardness
• bright surfaces
• oxidation and decarburisation-free surface zone
• little scaling, even on workpieces with a complex geometry
• constant qualities
• reproducibility
• usable for a broad range of materials

Ipsen offers a large number of horizontal and vertical single and multi-chamber furnaces, from which customers can select the furnace type best suited for their intended heat-treatment Processes and Products. All of the furnace models can be equipped with convection systems to increase furnace throughput by shortening heat-up times, and to minimise warping of delicate work pieces.

Rotary-hearth technology

Depending on the type of charge loading and workpiece geometry, there may be dead zones around the charge not seeing any flow or surfaces exposed to most of the cooling gas. To solve this problem, Ipsen has designed a rotary hearth for vertical furnaces whose speed of rotation can be adjusted in line with cooling requirements. This eliminates uneven gas flow distribution.
