UltraFlex using induction to preheat steel to 1742°F/950°C within less than 5 seconds
The efficient usage of induction heaters for fast preheating to 1742°F/950°C of steel shovel molds has recently been demonstrated by UltraFlex Power Technologies.
In this demo case, a potential customer from the Dies and Molds industry was looking to replace their current gas furnace-based preheating method with induction heating, to achieve faster heat cycles, repeatability and a uniform heating temperature. The customer was manufacturing steel shovels and the process required to preheat metal billets to a target temperature of 1742°F/950°
For this heating process UltraFlex engineers recommended the use of an Ultraflex SmartPower™ system. UltraFlex SmartPower™ Compac are a breakthrough innovation in induction heating. The latest SiC transistor technology and proprietary digital control algorithms they use ensure optimal performance and maximum efficiency in a wide frequency range.
UltraFlex designed a custom induction coil for this heating process, so multiple shovel molds could be preheated at the same time and the productivity largely increased. With SmartPower™ turned on, it took less than 5 seconds for all steel molds to reach the target temperature of 1742°F/950°
If used on the production line, this induction heating process would ensure increased productivity and high-quality, repeatable results, independent of the operator's skills. This would also be a safe process - both for the operator and the environment - with no smoke, waste heat, and noxious emissions.
