Presentation Title How to Prevent Porosity Defects in Steel Casting Component
Author(s) Izudin Dugic
On-Site Speaker (Planned) Izudin Dugic
Abstract Scope The production of steel casting is often very complicated and difficult. To produce quality castings it requires the casting to be clean and free from any defects. One of the main casting defects is hot tearing, also known as a crack or shortness. This phenomenon represents the formation of an irreversible failure (crack) in the steel semisolid casting. The second defect which very often occur in casting is porosity. Porosity is often used to describe any void or hole found in a casting. To control the porosity you need to understand its sources and causes. Porosity can occur either by gas formation, solidification shrinkage, or non-metallic compound formation, all while the metal is liquid. This experimental work is focused on reducing the porosity defects on steel casting component at a production scale. The produced casting component was strongly affected by porosity defects.
