Best Methods and the Role of Inoculant Wire Feeders
Best Methods to Make S G Iron or Ductile Iron : Spheroidal Graphite Iron (S G iron), also known as Ductile Iron, is a type of cast iron that exhibits excellent strength and ductility due to the presence of spherical graphite nodules in its microstructure. To produce high-quality S G iron, several key methods and techniques are employed: Material Selection: Start with high-quality raw materials, typically scrap iron, steel, and pig iron. These materials should have low levels of impurities to ensure a clean melt. Melting Process: The most common method is the electric induction furnace, where the raw materials are melted at high temperatures. Control over the melting process is critical to achieving the desired composition and temperature. Inoculation: Inoculation is a key step in S G iron production. It involves adding specific alloying elements, such as ferrosilicon and magnesium, to promote the formation of spherical graphite nodules. This step enhances the duc...
