SECO/WARWICK 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 product clean or to assist in surface treatments, the roller hearth furnace is a powerful tool for today’s manufacturing environment.
SECO/WARWICK process specialists to select the right combination for your production by configuring the furnace system with a variety of heating and cooling chamber designs, custom engineered to suit your process.
Roller hearth furnaces are ideal for full anneal of steel casings to improve machinability. These may also be used for stress relief anneal of castings or forgings. This furnace can be gas fired direct, gas radiant tube or electric ribbon resistor. Water jacketed cooling chambers are designed to cool rapidly, to work with excess air burners, and to improve convection heat transfer at the lower temperatures.
/ 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 QualityProduction: The advanced construction design features of these furnaces let you increase both the quality and rate of your production.
