Space-Saving System for Hot Stamping Large Blanks
April 1, 2025
The CRF system from Schuler and BSN requires about a quarter of the space of a comparable roller hearth furnace, Schuler reported.
"Conventional roller hearth furnaces have a length of up to 45 meters (148 feet) so that large components, such as side walls or floor groups, can be produced economically by hot stamping," said a Schuler spokesperson. "Heat treatment specialist BSN Thermprozesstechnik and Schuler have now developed a compact rotary furnace (CRF) system that saves space and energy, is easy to maintain and ensures a repeatable temperature of the heated parts. This is important because any deviation from the specified temperature can lead to inaccuracies and, therefore, problems during assembly."
With a length of 14 m (46'), including a loading and centering unit, a width of 6 m (20'), including heating and drives, and a height of 7 m (23'), the CRF system from Schuler and BSN requires only around a quarter of the space compared to a conventional roller hearth furnace, Schuler reported. The minimum cycle time per part is 12 seconds. The innovative furnace can run on electricity or gas, and it can save around 1,200 MWh of energy per year.
Schuler's Pressure Controlled Hardening (PCH) technology can be combined with the CRF system as an optional means to help ensure shorter cooling times and better forming tolerances.
