A straightening and peeling machine is a purpose-built industrial system for processing solid metal wire rods under Ø30mm diameter. It simultaneously performs oxide peeling (scale removal) and straightening through a unique mechanical process, delivering precision-shaped wire rods with superior surface quality – a critical pre-treatment stage for wire drawing operations.

Synchronized Processing Principle:

Mechanical Peeling (Scale Removal):
As wire rods pass through multi-roller units, controlled bending and compression forces induce brittle fracture in surface oxides (mill scale). This tool-free process efficiently removes rust, scale, and defects through pure mechanical stress – no cutting blades involved.

Integrated Straightening:
During the same roller sequence, precision-engineered rollers apply counter-bending forces to eliminate curvature. Both peeling and straightening occur simultaneously in one continuous pass.

Core Advantages:
▶ Synchronized Efficiency: Single-pass processing reduces handling by 50%
▶ Non-Destructive Peeling: Maintains material integrity and dimensional accuracy
▶ Precision Straightening: Achieves ≤0.5mm/m linearity (ISO 2768)
▶ Ø3-30mm Solid Rods: Exclusively for round wire rods (non-tubular)
▶ Zero Tool Costs: No consumable blades; hardened rollers last 10,000+ hours
▶ Wire Drawing Ready: Optimized surface and straightness for downstream processes
