Best Methods to Make S.G. or Ductile Iron Using Cored Wire System!
In modern foundry and casting industries, S.G. Iron —also known as Spheroidal Graphite Iron or Ductile Iron —has become a vital engineering material. Its excellent strength, toughness, and machinability make it a preferred choice for automotive parts, pipes, pumps, and machinery components. However, producing high-quality S.G. Iron requires precise control over magnesium treatment , which transforms the graphite structure from flakes to spheroids. Among the different nodularization methods available, the cored wire injection technique has emerged as one of the most efficient, consistent, and economical approaches. It is widely recognized as one of the best methods to make S G iron or ductile iron in modern metallurgical practices. This article explores how cored wire injection enhances the quality, yield, and efficiency of S.G. Iron production, explaining the process, advantages, and why this technique is revolutionizing ductile iron manufacturing. Understanding S.G. Iron an...
