Waste Rebar Rib Peeling and Straightening Machine – Cold Forming Precision for Reuse

Our Waste Rebar Flat Rolling Machine adopts advanced cold pressing technology to process used ribbed rebar into high-quality plain round steel bars. Capable of handling rebar diameters of 10–18mm and 20–30mm, the machine uses specially designed alloy rollers to perform multi-pass cold rolling and straightening, achieving one-time forming with zero roundness deviation, smooth surface finish, and excellent straightness — far superior to traditional two-roller or four-roller machines.
Key Features:
- Converts waste ribbed rebar into smooth round bars with precise dimensions.
- Combines rib removal, diameter reduction, and straightening in one process.
- Equipped with three powerful motors and a vertical-horizontal roller mechanism.
- Capable of correcting heavily bent rebar and producing high-straightness finished bars.
- Uses 9Cr2Mo alloy for straightening rollers, ensuring high hardness, wear resistance, and long service life.
- Efficient one-pass processing without the need for secondary operations.
