Description

Carbolite ESF 12-10 Hardening Furnace - General Description

Door Switch - All chamber furnaces (except those with mineral insulated elements) incorporate a safety switch which interrupts the heating element circuit when the door is opened. This prevents the user touching a live heating element - but, of course, the furnace will not heat up if the door is left open.

Ventilation - If the furnace is to be used for heating materials which produce smoke or fumes, the chimney must be correctly fitted and unobstructed. Otherwise, soot will accumulate in the chamber and between the layers of insulation, causing an electrical breakdown of the heating elements. Furnaces used for this kind of application must be heated regularly up to maximum temperature and held for one hour to burn away the soot.

Corrosive Materials - Materials such as case hardening compounds and other reactive salts readily penetrate the ceramic lining of the furnace chamber and attack the wire elements, causing premature failure. When such materials are being used, the furnace must be protected by a hearth plate or tray, preferably made from material such as Inconel.

Non-metallic hearth plates reduce the heat transmission from the bottom of the furnace, and increase the element temperature in this area. This may result in premature element failure, particularly if the furnace is working near to maximum temperature. Under these circumstances, it is recommend that the temperature be raised slowly over the last 300°c, allowing approximately 10 minutes soak at 100°c intervals.
