Si-Mn Cored Wires

Silicon Manganese Cored Wire is an efficient alloying material for molten steel, consisting of Silicon Manganese alloy powder encased in a cold-rolled steel strip. It uses the wire feeding technique to accurately and efficiently add silicon and manganese to molten steel, primarily for deoxidation and composition fine-tuning. It is a key tool for optimizing steelmaking processes and reducing production costs.

The production begins by crushing and milling standard SiMn alloy into high-purity powder of specific particle size. This powder is then continuously and uniformly fed into a steel strip via precision machinery. The strip is rolled and folded into a tightly sealed, continuous wire, which is finally wound into coils.

High Alloy Yield:​​ Deep injection minimizes element oxidation, achieving a yield rate of over 90% for Si and Mn, allowing for precise composition control.

Cost Reduction:​​ Reduces alloy consumption compared to traditional scattering methods, lowering production costs.

Improved Steel Quality:​​ Enhances deoxidation, purifies the molten steel, reduces inclusions, and increases steel cleanliness.

Easy Operation:​​ The mechanized feeding process ensures uniform composition and a better working environment.

Primarily used in the secondary refining process of Electric Arc Furnaces (EAF) and Ladle Furnaces (LF). Commonly applied for deoxidation and fine alloying adjustment of carbon steels and low-alloy steels.
