Mechanical descaling units

WiTechs mechanical descaling machines prepare wire surfaces by bending, following by, sanding, or brushing processes, supporting stable downstream drawing and improving overall line efficiency. Designed for a broad range of wire qualities, these systems help reduce die wear, prevent production interruptions, and deliver consistent surface conditions across continuous manufacturing operations. A stable quality output is what WiTechs delivers with their mechanical descaling solutions.

Bending descaling units – BBE and WEZ series

WiTechs bending descalers remove scale by cracking it off the wire surface through controlled bending across multiple rolls. This mechanical process ensures consistent descaling performance on a wide range of low- and high-carbon wire diameters and supports stable operation in drawing and pre-treatment lines.

Main features:

• Multi-roll bending systems for effective scale breaking, with roll number and bending direction depending on model
• Long-life tungsten carbide or ceramic inserts on all bending rolls
• Adjustable roll positioning for quick setup and easy wire infeeding in zero-position
• Optional integrated straightener or wire break control depending on configuration
• Scale collection by wagon, with screw conveyor optionally available
• Wire diameters starting at 4.5 mm
• Wire speeds up to 10.0 m/s

Sanding descaling units – SEZ series

WiTechs bending descalers remove scale by cracking it off the wire surface through controlled bending across multiple rolls. This mechanical process ensures consistent descaling performance on a wide range of low- and high-carbon wire diameters and supports stable operation in drawing and pre-treatment lines.

Main features:

• Automatic acceleration and deceleration of the flyer and belts during start and stop
• Grinding belt overlap can be installed, auto-adjusting at line speed
• Belt lifetime monitoring with warnings and safety functions
• Special grooved and coated belt rollers for long service life and dust removal
• Adjustable crowned top roller to keep the sanding belt centered
• Belt break safety system based on torque detection
• Multiple maintenance timers
• Easy-to-operate functions secured against unnecessary operator access
• Solid sealed body, no dust escapes with proper suction
• Belt tensioning adjustment
• Push-button belt release for safe belt change
• Automatic positioning of tension roller when doors close
• Dedicated dust-free lighting compartment
• Start/stop and reset of drawing line possible from sanding machine
• Total cost of ownership below €10 per metric ton of wire
• Diameter range up to 34 mm

Brush descaling units – WBE and Ecoclean series

WiTechs brush descalers remove rust, scale, and surface residues through high-efficiency brushing or rotating pad cleaning, depending on the model. Designed for stable performance across various wire qualities, they combine long service life with low operating costs and easy, operator-friendly handling.

Main features:

• Two or three brush pairs at 90° on brush-based models; Ecoclean with 24 rotating pads
• Automatic and autonomous brush re-adjustment on WBE models
• Long service life of brushes or pads, up to 3000 metric tons
• Low noise level and quick replacement
• Suitable for any wire quality; Ecoclean handles aluminium, stainless steel, copper, selected high-carbon
• Wire diameters from 3.0 to 18.0 mm
• Wire speeds up to 10.0 m/s

Together, these solutions deliver reliable wire surface preparation and support consistent performance across drawing and processing lines.
