How Cored Wire Improves Steel Treatment
Elimination of Continuous Casting Nozzle Clogging
By transforming solid inclusions into low-melting liquid droplets, cored wire treatment ensures smooth tundish nozzle flow, preventing costly sequence interrupts and strand losses.
Reduced Thermal Drop & Slag Layer Protection
High-speed wire injection penetrates the slag cover without exposing liquid steel to atmospheric reoxidation, reducing temperature loss and refractory wear.
Automated Operation & Enhanced Plant Safety
Replaces manual bulk additions with automated, remote-controlled wire feeding systems—reducing dust, worker fatigue, and exposure to molten metal splashes.

Manufacturing Process
Raw Material Powder Preparation
Alloy powders (CaSi, Ca metal, FeB, Carbon) are screened for precise particle size distribution and vacuum-dried to moisture levels ＜0.1%.
Steel Strip Uncoiling & Forming
Low-carbon steel strip is fed through multi-pass precision forming rollers to form a continuous U-channel.
Automated Loss-In-Weight Dosing
Powdered core materials are continuously metered into the steel channel using gravimetric feeders for exact linear mass control.
Seam Closing & Mechanical Crimping
Steel strip edges are folded, overlapped, and crimped under high pressure to lock in the core powder tightly.
Die Calibration & Sizing
The formed wire passes through calibration dies to achieve exact roundness, final diameter, and high powder density.
Precision Coil Winding
Finished wire is wound onto vertical or horizontal discharge coils under controlled tension to prevent tangling during high-speed unwinding.
Quality Control
Inline Laser Diameter & Weight Measurement: Dual-axis laser gauges measure wire diameter and linear powder weight continuously during production.
In-House Chemical Laboratory: High-frequency XRF, CS Analyzers, and ICP-OES verify alloy powder chemistry per batch prior to encapsulation.
Tensile & Seam Pull Testing: Mechanical testing confirms that steel strip welds and lock-seams exceed tensile standards.
Sampling Protocol: Samples are drawn every 2,000 meters in compliance with ISO 10720 and ISO 3713 standards.
Third-Party Inspection Ready: Fully compatible with pre-shipment sampling and testing by independent surveyors (SGS, AHK, Bureau Veritas, CCIC).
