Rotary Hearth Furnace

Rotary Hearth Furnace

The developing trend in materials engineering continues to push towards smaller work pieces with “thin” walled geometry. This is especially true within the automotive industry where thin walled supporting components (ex. internal transmission parts) are called upon to illustrate significant hardness values while retaining stringent deformation characteristics. Arbitrating between minimizing material costs and meeting performance specifications represents the daily struggle manufacturers encounter. In support of this effort, Aichelin is pleased to offer a complete system approach that ensures quality heat-treated parts while minimizing deformation behavior.

The benefit of the rotary hearth furnace is the ability to process material within a piece by piece format while maintaining maximum throughput within a limited workspace. The Aichelin advantage is best represented by our complete system«s solution offering including precision controlled rotary furnace with supporting press-quench and temper furnace. Aichelin«s capabilities within this forum are well documented and have been published within recognized trade publications such as “Industrial Heating”.

Applications Include:
Treating individual pieces one at a time.
Gear components, bearings, clutch components, torque converters and transmission components.
Typically used in conjunction with hardening equipment, as an example press quench. Utilized when deformation is a major concern.
Typical working temperatures up to 1000ºC / 1840°F
Processes Include:
Hardening (in conjunction with other equipment)
Gas Carburizing
Carbonitriding
Austenizing
Annealing
Heating up
