1.What Is a Roller Hearth Furnace?
A Roller Hearth Furnace is a continuous industrial furnace that transports workpieces through heating and cooling zones using a series of rotating heat-resistant rollers. This furnace design provides excellent temperature uniformity, continuous production capability, and efficient material handling, making it one of the most widely used heat treatment systems in modern manufacturing.
Roller hearth furnaces are commonly used for:
- Heat Treating
- Annealing
- Hardening
- Tempering
- Solution Heat Treatment
- Normalizing
- Stress Relieving
- Aluminum Heat Treatment
Compared with traditional batch furnaces, roller hearth furnaces offer higher production efficiency, better dimensional consistency, reduced labor costs, and improved process automation.
Since the furnace operates continuously at elevated temperatures, critical components—including furnace rolls, heat treatment baskets, alloy trays, furnace fixtures, and other industrial furnace parts—must withstand severe thermal cycling, mechanical loading, oxidation, creep deformation, and long-term wear.
ECOOSUN designs and manufactures custom roller hearth furnace components according to customer drawings, furnace dimensions, and operating conditions, providing long-lasting solutions for industrial heat treatment systems worldwide.

3. Recommended Heat-Resistant Alloys for Roller Hearth Furnace Parts
The operating temperature inside a roller hearth furnace can exceed 1000°C, requiring carefully selected heat-resistant alloys capable of maintaining mechanical strength during prolonged exposure to high temperatures.
ECOOSUN recommends different materials depending on operating conditions.
| Material | Typical Application |
|---|---|
| HK40 | Furnace Rolls, Trays, Baskets |
| HU | Heavy Duty Furnace Fixtures |
| GX40CrNiSi25-20 | High Temperature Furnace Components |
| Custom Heat-Resistant Alloy | Special Furnace Designs |
Material selection depends on:
- Furnace temperature
- Product weight
- Continuous operating time
- Thermal cycling frequency
- Furnace atmosphere
- Maintenance intervals
Our engineering team helps customers select the optimal alloy to maximize component life while reducing maintenance costs and production downtime.
