A Roller Hearth Furnace is a continuous heat treatment furnace that uses rotating rollers to transport materials through various heating zones. These furnaces are ideal for high-volume processing in industries like automotive, aerospace, steel, ceramics, and glass manufacturing.

Types of Roller Hearth Furnaces

Gas-Fired Roller Hearth Furnace
- Uses natural gas, LPG, or diesel burners.
- Suitable for metal heat treatment, forging, and sintering.
Electric Roller Hearth Furnace
- Uses electric resistance heating for precise temperature control.
- Common in electronics, ceramics, and aerospace industries.
High-Temperature Roller Hearth Furnace
- Designed for applications above 1200^oC.
- Used for glass tempering, ceramic sintering, and steel hardening.
Atmosphere-Controlled Roller Hearth Furnace
- Uses controlled gases (nitrogen, hydrogen, argon, etc.) for oxidation-free processing.
- Ideal for brazing, sintering, and carburizing applications.
