Overview

Bell furnaces are industrial heat-treating ovens used for processes such as annealing, tempering, and carburizing. They are characterized by their removable bell-shaped covers, which enclose the workpiece during heating. Bell furnaces offer uniform heat distribution, making them ideal for applications requiring precise temperature control.
