JR FURNACE roller hearth furnaces are designed to heat treat a wide variety of products economically with uniform, repeatable results. There’s a wide range of sizes of electric or fuel-fired heating systems with matched cooling sections and material handling systems. Coupled with a protective atmosphere to keep products clean or to assist in surface treatments, the roller hearth furnace is a powerful tool for today’s manufacturing environment.
Features of Roller Hearth Furnace:
- Continuous, Unlimited Work Flow: Roller hearth conveyor system consists of a series of externally driven rolls. There are no cumulative conveyor pressures or tensions as in belt, chain or pusher furnaces. As a result, there are no production or cycle limitations and the length of the furnace is dependent only upon your application needs. Individual operation of the roll sections permits continuous or interrupted workflow.
- Fast, Top Quality Production: The advanced construction design features of these furnaces let you increase both the quality and rate of your production. Individually driven roll sections for fast run-in and run-out, heavy-duty insulation systems, welded gas-tight casings, temperature-designed doors-all assure fast, accurate, uniform heating and cooling, minimizing atmosphere mixing, heat loss and work distortion or stress.
- Ease of Installation: Furnace sections are completely assembled at the factory with insulation, heating systems, piping, wiring, and rolls. The skid-mounted sections can be moved quickly and easily into place, welded or bolted together and placed in operation. Assembly by highly skilled factory staff using the right tools, jigs and fixtures assure greater attention to workmanship and design details, eliminating many of the problems frequently encountered with field construction.
- Approach to extend component life: Because individual conveyor rolls are externally driven and remain in the same temperature zones, they are not subject to thermal cycling and can be designed for maximum operation life at working temperatures. In addition, cumulative pressures on conveyor rolls, work trays and workloads are eliminated. Furnace doors are specially constructed and insulated for operation within the temperature zones in which they are located, minimizing stress and warpage caused by temperature differences. Heating and cooling sections incorporate dependable, high-quality components for long life operation. Factory assembly of the furnace section eliminates many problems often encountered with field construction.
