Historically Etchells OEM Series Eleptical Forging Furnaces have traditionally been lined with High Alumina Furnace Bricks and a high density castable lining, which whilst having the ability to withstand the arduous conditions of the drop forging furnace environment are inherently not energy efficient.

The heat up time from ambient to forging temperature can be a significant factor in production considerations; this is principally due to the time taken to overcome the thermal inertia of the refractory lining and bringing billet stock up to forging temperature.
