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 roller hearth furnace 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.
-
Flexible Operation:Individual roll sections can be started, stopped, reversed or oscillated; they can be run at the same or different speeds. This permits an operating furnace
that produces your required cycle in a minimum amount of space. High-speed transfer between sections allows closely spaced workloads or work trays, with separation during transfer through doors,
assures the optimum use of hearth space and minimizes atmosphere mixing. All door openings can be adjusted to workload heights, permitting faster operation and minimizing atmosphere mixing.
-
Lower Product Costs:The wide selection of furnace combinations and sizes means that you can get the furnace designed for your needs. You can cut costs through increased product
quality and rate of production. Factory assembly means lower cost installation and your furnace is in production more quickly. In addition, the best construction materials and design mean minimum
maintenance.
-
Cycle Annealing:Cycle annealing produces a tough, uniform structure in steel. Typical applications include improving the machinability of screw machine stock, improving cold
working properties of deep drawing stock, and improving impact resistance & fatigue properties of gears or machine parts. In the furnace, the steel is heated to slightly above hardening
temperature (approx.925°C), cooled quickly to the temperature at which transformation should take place (approx. 650°C), held at this temperature until the transformation has taken place and then
cooled. Thisroller hearth Furnace
