Our customer’s current process uses resistive ovens to heat brass rods. They want to improve safety, productivity, and reduce energy costs, by using induction instead of resistive heating. To maximize productivity, they want to be able to heat 3 brass rods at a time to 1436°F (780°C) within 25 seconds. For this application test, we are only heating one rod. Our goal is to heat the single rod to 1436°F (780°C) within 25 seconds with less than 30 kW of power. This will ensure that when heating 3 rods, the 100 kW system will meet the production requirements.
