How To Select a Furnace

"Heat Treating Furnaces" also known as hardening furnaces

Heat treat (Hardening) furnaces have higher heat output power than draw furnaces due to the elevated temperatures at which they operate. Heat transfer to the tool steel is accomplished by a very efficient process called direct radiation. Temperature uniformity in these furnaces is best in the red heat range. Normal maximum temperature is 1232°C (2250°F). Optional 1316°C (2400°F.) maximum temperature versions are available.

Uses: These furnaces are designed for general use in the shop, laboratory or factory where temperatures from 300°F to 2250°F ±25 °F are required. They are used for heat treating metal, assaying and all types of testing. 2400° F maximum temperature option available at additional cost.

Temperature Controls: Auto tuning microprocessor-based controller.

Heating elements: Alloy wire elements are coiled and mounted on the side walls in easy to change porcelain plates.

General construction: The furnace case is constructed of heavy gauge sheet steel and finished in gray hammertone. The walls and door are constructed of the finest quality insulating fire brick backed up by 1800°F block insulation.

Safety switch: These models come equipped with dual door safety Switches. when the door is opened, power is disconnected from the heating Elements.

Door: The counter balanced easy to operate door, opens up and away from the furnace, keeping the hot side away from the operator.

A Kaowool® rope seal is installed on the door where it meets the Chamber.
