SS316 Furnace Roller Brush

A SS316 Furnace Roller Brush is a rotating cylindrical cleaning tool that installs directly onto a furnace line, conveyor, or roller maintenance station. Instead of a handle, the brush has a central shaft that couples to the drive motor. As the brush rotates, SS316 wire bristles sweep across the surface of a furnace roller, hearth roller, or the underside of a moving product to dislodge oxide scale, dust, and other loose residues that accumulate during heating cycles.

The brush is not a hand tool. It is an inline or offline cleaning component designed for continuous rotation at a controlled speed. In most installations it is positioned to contact the furnace roller while the roller is still turning, or it is mounted in a dedicated roller cleaning station that rotates the roller against the brush. Because the brush itself is driven, the operator does not apply manual pressure; the brush rotation speed and the engagement depth between brush and roller control the cleaning force.

The SS316 wire bristles are the primary working element. The wire diameter, trim length, and fill density determine how aggressively the brush cleans and how much heat it can tolerate before the bristles lose their spring. The central core is also made from AISI 316 stainless steel so that the entire rotating assembly remains corrosion-resistant, including the shaft area that sits close to the furnace heat or process fumes.

This is a tool for maintaining furnace rollers and the product surfaces that pass over them. It removes the light, friable oxide layer and loose contamination that builds up between furnace runs. It is not a replacement for shot blasting, chemical descaling, or grinding when the roller has developed a thick, hard, tightly bonded scale layer larger than a few hundred microns. In those situations the brush can be used as a finishing step after heavier mechanical removal, but it will not strip heavy mill scale on its own.

The following table lists the standard configuration for this roller brush. All dimensions and wire parameters can be adjusted for a specific furnace line.

The standard brush length and diameter shown above can be changed to match the furnace roller width, the available mounting space, and the required contact arc. Quick-change coupling designs are configured to fit the customer’s existing drive shaft or roller journal.

• Roller hearth furnaces in steel, stainless steel, and specialty alloy heat treating, where oxide and dust from the product build up on the hearth rollers and transfer back onto the strip or plates.
• Continuous annealing and normalizing lines that run strip, wire, or tube through a furnace on driven rollers; the brush cleans the rollers offline during scheduled maintenance to restore surface finish.
• Galvanizing and coating lines where the entry or exit rollers pick up zinc dust, oxide, or dross particles that must be removed before they mark the coated surface.
• Glass tempering and ceramic kiln roller conveyors where roller surfaces collect fine particles, glass chips, or glaze dust that cause product defects.
• Powder metal sintering and brazing furnace lines where loose metallic powder and binder residue adhere to the conveyor rollers and must be swept off without contaminating the next batch.
• Any high-temperature conveyor system where rollers are exposed to heat, combustion byproducts, or process dust and where a corrosion-resistant wire brush is needed to prevent rust contamination on the product.

Furnace roller brushes are rarely one-size-fits-all. We can adjust the brush to your roller dimensions, your residue, and your existing drive interface. To configure a custom brush, provide the roller width and diameter, the residue type and thickness, the operating temperature, the line speed or desired brush RPM, and a drawing or photo of the current mounting arrangement.

We can change:

• Brush geometry — outer diameter, face length, end chamfers, spiral or straight wire fill pattern, and multi-diameter profiles if the roller has a crowned or stepped surface.
• Wire fill — wire diameter, trim length, fill density, wire direction, and mixed wire configurations (e.g., stiffer wire at the edges where scale accumulates).
• Core and shaft — SS304, SS316L, or higher alloy core; solid or hollow core to reduce rotating mass; custom shaft length, keyway, spline, or quick-change adapter.
• Quick-change coupling — matching half-coupling, torque rating, axial retention, and safety locking mechanism.
• Special requirements — dynamic balancing to specific RPM, anti-spark bronze or copper alloy wire inserts for explosive atmospheres, or wire replacement modules that allow the core to be reused.
• Project support — material certificates for the SS316 wire and core, hardness and corrosion test reports, drawing approval, and third-party inspection for critical furnace installations.
