Rotary Hearth Furnace is designed for heat treating,
bloom reheating in seamless pipe mills, calcining, carbon based DRI
production and metal reclamation. Rotary hearth furnace comes in
different sizes. They are either electrically heated or gas-fired and
are suitable for continuously hardening such parts as gears requiring
press quenching, or pre-heating copper, brass, and bronze slugs and
billets prior to forging or impact extrusion.
Features
The features of the rotary hearth furnace are:
Buying Tips
Following should be the consideration before buying the
industrial rotary hearth furnace:
- The temperature or the heat is homogeneously.
- The insulation should be proper.
- How door is operating.
- What types of elements are used for heating.
- The size you are purchasing will fit properly in your working
place.
- What is the application for which you are buying the furnace.
|
- Some Rotary hearth furnace can be operated at variable speed.
- They are fabricated from continuously welded and reinforced steel
shell.
- They have long-term stability with minimal resistance around the
outer wall of the furnace. This is achieved through low watt-density
rod over bend elements with round cross-section.
- Normally elements are removable from the top of the furnace.
- Excess temperature instrument.
- Water-cooled oil seal at the hearth.
- Door is operated Pneumatically.
- Low temperature furnaces Consist of high alloy recirculating fan.
- Space efficiency.
- Versatile processing capabilities.
- Continuous operation.
Advantages
Following are the advantages of rotary hearth furnace:
- Temperature inside the furnace is uniform which can be charged or
discharged from the same door.
- Parts which are sensible to distortion can be quenched
individually.
- Parts that vary in shapes and sizes are given proper heat
treatment.
- Hardening depth in gas carburizing as well as carbonitriding
process drive with simple and safety operation.
- While handling thin walled parts Charge carriers serve as energy
storage.
Applications
Following are the applications of rotary hearth furnace:
- Bloom / billets reheating for seamless pipe mills
- Reheating for forging applications
- Heat treating of wire coils
- Heat treating of large pipes
- Carbon baking
- Glass parts thermal treatment
- Calcining of coal & carbon products
- DRI production from ore or from waste material
- Iron nugget production
- Hardening
- Pre-heating
- Normalizing
