Role of Magnesium Cored Wire Injection in High-Quality Ductile Iron Production
In today’s competitive manufacturing world, foundries are under constant pressure to produce stronger, lighter, and more reliable cast components while keeping costs under control. Ductile iron (also known as SG iron or nodular iron) plays a critical role in industries such as automotive, construction, agriculture, pipelines, heavy machinery, and infrastructure. However, the true performance of ductile iron depends heavily on how magnesium is added during treatment. Traditional methods like tundish cover, sandwich method, or bell treatment often lead to inconsistent results, higher magnesium loss, safety risks, and variable quality. This is where the Magnesium Cored Wire Injection System has transformed ductile iron production. It offers precision control, improved nodularity, reduced fade, higher recovery, enhanced safety, and consistent casting quality. This article explains in simple, practical terms: What magnesium cored wire injection is How it works Why it is essential for produ...
