The Biggest Mistakes Foundries Make When Using Ferro Silicon Magnesium
In the world of ductile iron casting, ferro silicon magnesium (FeSiMg) is not just another additive—it’s the backbone of spheroidisation. When used correctly, it transforms brittle gray iron into strong, flexible ductile iron. But when used incorrectly, it can quietly ruin casting quality, increase rejection rates, and push production costs higher than expected. Many foundries believe they are using ferro silicon magnesium “correctly,” yet still struggle with issues like poor nodularity, inconsistent results, or excessive slag. The truth is, small mistakes in handling, selection, or process control can have a massive impact—especially during Ductile Iron Treatment , where precision is critical. This article breaks down the most common mistakes foundries make when using ferro silicon magnesium, along with practical insights to help you avoid them and improve your casting results. Choosing the Wrong Grade of Ferro Silicon Magnesium One of the most overlooked mistakes is selecting the wro...
