Why Cored Wire Injection is The Most Efficient Method for FeSiMg Alloying

In the highly competitive foundry and steel industry, efficiency is the key to success. Every process — from alloying to casting — needs to deliver consistency, safety, and cost savings. Among these, Ferro Silicon Magnesium (FeSiMg) alloying plays a critical role, especially in the production of spheroidal graphite (SG) iron, also known as ductile iron.

Traditionally, magnesium was added to molten metal through ladle additions. While effective to some extent, this method came with significant drawbacks such as high magnesium losses, safety concerns, and inconsistent results. Today, however, a smarter and more efficient solution exists — cored wire injection.

The Challenge with FeSiMg Alloying

FeSiMg (Ferro Silicon Magnesium) is essential in SG Iron Treatment, where it modifies the graphite structure and transforms ordinary cast iron into high-strength ductile iron.

But here’s the catch — magnesium is highly reactive. Traditional ladle addition methods waste a big chunk of it through violent reactions and oxidation. That means:

• Lower recovery rates

• Inconsistent results

• Higher costs

Clearly, something smarter is needed.

Enter Cored Wire Injection

Imagine being able to feed FeSiMg directly into molten metal with precision, consistency, and almost no waste. That’s exactly what Cored Wire Injection does.

By packing FeSiMg inside a steel wire and injecting it deep into the molten iron, foundries achieve controlled reactions, higher efficiency, and better safety.

Why Foundries Prefer It

Here’s why cored wire injection has become the go-to method for FeSiMg alloying worldwide:

Maximum Magnesium Recovery – Say goodbye to 40–50% losses. The process ensures the alloy reacts where it should — inside the melt, not on the surface.
Consistent Results Every Time – Uniform distribution of FeSiMg means your SG iron gets the same strength and quality across batches.
Cost Savings That Add Up – Less waste + precise control = lower production costs without compromising quality.
Improved Safety – No more violent splashes or uncontrolled reactions. The deep injection method keeps your team safer.
Cleaner & Greener Process – Reduced slag, fewer emissions, and less alloy wastage make it an environmentally responsible choice.

Beyond Efficiency – A Smarter Future

Whether you’re producing crankshafts, gears, pipes, or heavy machinery parts, your reputation depends on consistent quality. Cored wire injection with FeSiMg ensures every casting meets the highest standards.

It’s not just about efficiency — it’s about running a smarter foundry, staying competitive, and delivering reliable results to your customers.

Final Thoughts

Traditional methods served their time, but the future belongs to technologies that give better recovery, precision, and safety. That’s why cored wire injection is recognized as the most efficient method for FeSiMg alloying.

For foundries aiming to cut costs, improve quality, and boost productivity, the choice is simple: switch to cored wire injection and transform the way you handle FeSiMg.
