Graphite flotation in ductile iron castings: definition ...

1-11-1990 · Carbon float is defined as carbon segregation at the top surfaces of ductile iron castings caused by the buoyancy of graphite particles in liquid iron. Flotation of hypereutectic nodules occurs in ductile irons having carbon equivalents greater than 4.5 as defined by the expression CE = C% + (Si% / …

Ductile Iron Data - Section 3 - Part 1

Graphite flotation can cause a serious degradation of properties near the upper (cope) surface of large Ductile Iron castings. However, this phenomenon is readily avoided by reducing the carbon equivalent as the casting section size increases. Back to top. Effect of Carbide Content

Addressing Chunky Graphite in Heavy-Section DI …

Q: Chunky graphite continues to be a problem in our heavy-section ductile iron castings. We typically see this defect in the last-to-solidify areas of our castings. At times, following riser removal we see a discoloration on the casting surface, and further investigations generally show a microstructure that is indicative of chunky graphite.

Ductile iron - Wikipedia

Ductile iron, also known as ductile cast iron, nodular cast iron, spheroidal graphite iron, spheroidal graphite cast iron and SG iron, is a type of graphite-rich cast iron discovered in 1943 by Keith Millis. While most varieties of cast iron are weak in tension and brittle, ductile iron has much more impact and fatigue resistance, due to its ...

Graphite Flotation - Metal and Metallurgy …

6-1-2010 · I need some technical help; I have a situation where I need to take decision on a casting with graphite flotation. So I would like to know if you have some information (an equation or something) to correlate mechanical properties and graphite flotation (from micro-structure), so that I can predict the drop in mechanical properties (roughly).
