72 fesi powder in the welding rod industry

1. High-efficiency deoxidation, improving steel quality

During the steelmaking process, excessive oxygen content can lead to increased brittleness of the steel. 72 silicon iron powder can quickly combine with the oxygen in the molten steel to form SiO₂ slag, significantly improving the purity and mechanical properties of the steel.

✅ Advantages:

The deoxidation efficiency is higher than that of aluminum, and it reduces inclusions in the steel.

Suitable for various steel types such as plain carbon steel, stainless steel, and special alloy steel.

2. Optimize casting performance and improve the strength of castings

In the production of cast iron, 72 silicon iron powder serves as a nurturing agent, which can promote the precipitation of graphite and enhance the tensile strength and wear resistance of the castings. It is widely used in automotive parts, machine tool castings, and other fields. 

✅ Advantages:

Improve the cutting processing performance of cast iron.

Reduce casting defects such as shrinkage porosity and pores.

3. Key reducing agent in magnesium production

In the pyrolysis magnesium production process, 72 silicon iron powder reacts with dolomite (MgO) to efficiently reduce magnesium vapor, which is one of the core materials for magnesium production.

✅ Advantages:

The recovery efficiency is high, and the magnesium recovery rate has been improved.

The cost is lower than that of pure silicon, and the economic benefits are remarkable.
