1.4848 Furnace Roll Ø140 × Ø122 × 4000 mm | FH® Alloy Manufacturer

1.4848 Furnace Rolls – Ø140 × Ø122 × 4000 mm Heat-Resistant Roller for Industrial Furnaces

FH® Alloy manufactures customized 1.4848 furnace rolls for roller hearth furnaces, continuous heat treatment lines, annealing furnaces, normalizing furnaces, and other high-temperature conveying systems.

This furnace roll is manufactured with a nominal size of Ø140 × Ø122 × 4000 mm, referring to an outer diameter of 140 mm, an inner diameter of 122 mm, and an overall roller-body length of 4000 mm, subject to final drawing confirmation.

The long hollow roller body is designed to support and transport metal products through high-temperature furnace zones while maintaining reliable rotation, dimensional stability, and resistance to thermal deformation.

🔥 Product Overview
Furnace rolls operate continuously inside industrial furnaces, where they are exposed to high temperatures, mechanical loading, repeated thermal cycling, oxidation, surface scale, and furnace-atmosphere corrosion.

The 1.4848 furnace roll supplied by FH® Alloy is designed for applications requiring:

• High-temperature oxidation resistance
• Stable conveying performance
• Resistance to thermal cycling
• Controlled straightness over a long roller body
• Reliable connection between the roller tube and shafts
• Customized shaft and drive-end machining
• Long-term operation in continuous furnace lines

The hollow roller structure helps reduce overall weight and thermal mass while providing the required load-bearing capacity for the specified furnace application.

⚙️Main Product Specifications

All dimensions, tolerances, shaft structures, and connection details are manufactured according to approved customer drawings.

🧱 1.4848 Heat-resistant Steel Material

📐 Long Hollow Roller Design
The Ø140 × Ø122 × 4000 mm furnace roll has a nominal wall thickness of approximately 9 mm.

This hollow structure is suitable for long furnace rollers where the design must balance:

• Mechanical strength
• Roller-body weight
• Thermal expansion
• Rotational stability
• Heat absorption
• Shaft loading
• Manufacturing cost

For a roller body with a length of 4000 mm, straightness, concentricity, wall-thickness consistency, and shaft alignment are particularly important.

FH® Alloy evaluates the roller according to the actual load and operating conditions to reduce the risk of:

• High-temperature bending
• Excessive radial runout
• Uneven rotation
• Shaft misalignment
• Weld cracking
• Premature roller deformation

🏭 Typical Applications
This 1.4848 furnace roll can be used in a wide range of industrial thermal-processing equipment, including:

• Roller hearth furnaces
• Continuous annealing furnaces
• Normalizing furnaces
• Quenching and tempering lines
• Steel plate heat treatment furnaces
• Stainless steel annealing lines
• Tube and pipe heat treatment furnaces
• Forging heat treatment lines
• Casting heat treatment furnaces
• Continuous industrial heating systems
• High-temperature material-conveying equipment

Typical conveyed products include:

• Steel plates
• Metal sheets
• Pipes and tubes
• Bars and profiles
• Forgings
• Castings
• Mechanical components
• Heat-treated metal assemblies

🌡️ Operating Conditions to Consider
The service life of a furnace roll is influenced by more than the alloy grade.

Before manufacturing, FH® Alloy recommends evaluating the following operating parameters:

• Maximum furnace temperature
• Normal operating temperature
• Furnace atmosphere
• Workpiece weight
• Roller spacing
• Rotational speed
• Continuous or intermittent operation
• Heating and cooling frequency
• External shaft temperature
• Bearing arrangement
• Cooling method
• Scale buildup on the roller surface
• Required service life

For long rollers, the combination of operating temperature, span length, and workpiece load is especially important.
An unsuitable wall thickness or shaft structure may result in bending even when the alloy itself has adequate heat resistance.
