Ferrosilicon Magnesium With Rare Earth

Rare earth ferrosilicon magnesium alloy is a multi-component alloy that plays an important role in modern industry and is widely used in steel, nonferrous metals, casting and other fields.

Deoxygenation

 Better deoxidation effect:

Rare earth elements have strong deoxidation ability and can combine with oxygen in steel to form stable oxides. Compared with traditional deoxidizers such as ferrosilicon and ferromanganese, re ferrosilicon magnesium alloys deoxidize more thoroughly and can reduce the oxygen content in steel to a lower level, thereby reducing the degradation of steel performance and the increase in inclusions caused by excessive oxygen content. etc. questions.

 Deoxidation products are easy to remove:

The oxides formed after deoxidation of rare earth fesimg alloys usually have smaller sizes, lower melting points, lighter specific gravity, and are easy to float up and discharge molten steel. However, the oxides formed after deoxidation of ferrosilicon by traditional deoxidizers Silicon inclusions are refractory and difficult to float.

deterioration

 Remarkable grain refining effect:

RE silicon ferro magnesium alloy, as a modifier, can more effectively refine the grain structure of steel. Although traditional modifiers such as aluminum and iron can also play a certain role in refining grains, rare earth elements are more effective in this regard, making the grain size smaller and the structure more uniform and dense, thus improving the quality of steel. Strength, toughness, wear resistance and fatigue resistance, etc.

 Improve the shape and distribution of inclusions:

This alloy can make long strips or sheet-like inclusions in steel into spherical or nearly spherical shapes, reducing the splitting effect of inclusions on the steel matrix. Traditional modifiers are relatively weak in improving the morphology of inclusions, while rare earth elements and magnesium in ferro silicon magnesium alloys can better modify and spheroidize inclusions and improve the overall performance of steel.

Alloying

 Synergy of multiple elements:

Rare earth ferro silicon magnesium alloy contains silicon, rare earth, magnesium and other elements. These elements can synergize with each other in steel and exert a variety of beneficial effects. However, traditional alloyed deoxidizers or modifiers often contain only a single or a few elements and have relatively single functions.

 Improve special properties:

The addition of rare earth elements can also improve the heat resistance and corrosion resistance of steel, giving the steel better performance in high temperatures and corrosive environments. Traditional deoxidizers and modifiers generally do not have the function of improving special properties, and require the addition of other alloying elements or the use of special processing techniques to achieve this.
