What Is The Price Of Cored Wire? What Is Alloy Cored Wire?
Leave a message
Alloy cored wire is a metallurgical composite material made by wrapping specific alloy powder with cold-rolled low-carbon steel strip (thickness approx. 0.4 mm) to form a wire-shaped structure with a diameter of 13 mm ± 0.6 mm. The core material composition is customized according to functional requirements, for example:
Deoxidation/desulfurization: silicon-calcium powder (Ca 28-32%), pure calcium rod (Ca ≥ 97%);
Alloying: titanium-iron powder, boron-iron powder, carbon powder (≥96%);
Inclusion modification: rare earth silicon, magnesium alloy powder.

The core function of alloy cored wire
Precise composition control
Deoxidation and desulfurization: Silicon-calcium core powder reacts with oxygen and sulfur in the molten steel to form low-melting-point compounds that float to the surface, reducing oxygen content to ≤8 ppm and achieving a desulfurization rate exceeding 30%;
Alloy fine-tuning: Carbon core wire achieves carbon content control within ±0.02%, while titanium/boron iron wire optimizes grain size.
Solving Metallurgical Technical Challenges
Eliminating Continuous Casting Nozzle Blockages: Calcium treatment converts high-melting-point Al₂O₃ inclusions into liquid calcium aluminate (melting point <1400°C), reducing continuous casting interruption rates by 90%;
Improving casting quality:
Magnesium alloy wire (Mg 20-32%) replaces the injection method in ductile iron, achieving a spheroidization rate >90%;
Nucleating agent wire (silicon-barium, etc.) enhances graphite nucleation, increasing the tensile strength of castings by 15%.
Economic benefits and environmental advantages
Cost reduction: Alloy recovery rate increased by 15-20% (calcium recovery rate from <5% to 25-40%), reducing per-ton steel production costs by 20%;
Green production: Closed-loop feeding reduces alloy dust by 85% and prevents secondary oxidation of molten steel.
Applications of alloy cored wire
Out-of-furnace refining (LF furnace/ladle furnace)
Silicon-calcium wire purifies inclusions, while pure calcium wire deeply desulfurizes;
Continuous casting preparation
Controls the composition of molten steel in the tundish to prevent casting defects.
Ductile iron:
Nickel-magnesium core wire achieves smoke-free spheroidization treatment;
Grey iron:
Silicon-barium inoculant wire refines graphite flakes, improving mechanical properties.
