Why Slag Inclusion Occurs in Ductile Iron and How Foundries Can Stop It

Image
In today’s competitive casting industry, delivering high-quality ductile iron components is no longer optional—it is essential. Automotive, infrastructure, machinery, and engineering clients expect castings that meet strict dimensional, mechanical, and surface standards. Even minor defects can lead to rejection, rework, delayed shipments, and damaged business relationships. One of the most common and costly defects in ductile iron production is slag inclusion. These non-metallic impurities trapped inside castings weaken the structure, reduce performance, and increase scrap rates. For foundries focused on long-term growth and customer satisfaction, Eliminating Slag Inclusion Defects Of Ductile Iron Castings must be a top priority. In this article, we explain why slag inclusion occurs, how it affects casting quality, and what practical steps foundries can take to prevent it. We also share proven industry practices followed by experienced suppliers like Bansal Brothers to ensure clean an...

How Should Foundries Handle High Sulphur Metal During S G Iron Treatment?

Image
Sulphur control remains one of the most critical challenges in S G iron production. Many foundries today work with high-sulphur base metal due to scrap availability, cost pressure, and raw material variability. But the big question remains: How should foundries handle high-sulphur metal during S G iron treatment without compromising quality, nodularity, and cost efficiency? This blog explores the practical, metallurgical, and business-focused answers—with a special focus on S G Iron Treatment with High Sulphur Metal , the role of Ferro Silicon Magnesium, and how to achieve consistent Mg recovery in real foundry conditions. Why Is High Sulphur a Major Concern in S G Iron Treatment? Sulphur is a strong magnesium-consuming element. During S G iron treatment, magnesium reacts aggressively with sulphur before it can perform its primary role—graphite spheroidization. Key problems caused by high sulphur metal: Excessive magnesium loss Poor nodularity Inconsistent mechanical properties Higher ...
