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 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.
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.
Roller Hearth Furnace Advantages:
/ Energy recuperation is easier and less costly with continuous systems
/ Continuous takes up about half of the floor space than multiple batch units
/ Longer equipment life – typically 40+ years
/ Temperature ranges from 400°F – 2250°F (200°C – 1,200°C)
/ Suitable for atmospheres from air or products of combustion to exothermic (EXOGAS™), Endothermic (ENDOGAS™), Nitrogen/Hydrogen or Ammonia (AMMOGAS™) or steam
/ Throughputs are unlimited but typically from 500 pounds (225 kg) to 15,000 pounds (6,800 kg) per hour
