How To Select a Furnace

"Draw Furnaces" also known as annealing, tempering or forced
Draw furnaces are used for tempering and other low temperature processes. They normally operate at temperatures below red heat range where heat transfer to the tool steel is accomplished by the process of convection heat transfer. To increase convection efficiency, these furnaces are equipped with a fan in the heating chamber to move air (Forced Convection). This delivers a temperature uniformity of ± 6°C (± 10°F) or better. Maximum temperature is 677°C (1250°F.). Optional 1093°C (2000°F.) maximum temperature versions are available

Uses: These furnaces are designed primarily for annealing glass, and use as a bake out oven. However, it can be used for any purpose requiring controlled temperatures of up to 2250°F. When enquiring, please state temperature desired.

Controls: These furnaces come standard with a digital programmable main control and a digital high limit safety control. Solid state power switching to the heating elements, and dual door limit safety switches that interrupt power to the elements when the door is opened.

Elements: High temperature alloy wire elements are mounted in grooves in the brick walls. The design of the heating coils provides all around heating and close gradients throughout the furnace chamber.

General Construction: Heavy angle steel frame with 18 gauge sheet metal panels form the case. The walls are constructed of 4.5" of the finest quality insulated firebrick backed up by 1800°F block insulation. Counterweight lid opens easily. The lid is insulated with ceramic fiber. This combination of insulation and wall thickness helps to give fast heat up and excellent heat retention for economical operation.
