SUMMARY:Improved solidification structure in high alloy steel grades by an advanced Super-Swirl from Vesuvius
DESCRIPTION:The achievement of a sufficiently homogeneous solidification structure in the as-cast state already represents a decisive qualitative aspect in the production of high-alloy steel grades that are used for applications such as roller bearings, crankshafts, or components for the engine. The production of these applications belongs to the engineering long segment. Specific standards for round, square, and rectangular formats have been developed by the end customers to achieve the requirements for internal quality and mechanical properties. Over the years, when casting high carbon & high alloy grades, the use of an EMS (Electromagnetic stirrer) has become a standard. 

The declared goals for the semi-finished product of high-carbon grades are to achieve a high proportion of equiaxed area, to reduce segregation, and to avoid cavities in the as-cast product. 

A new generation of swirl designs was tested on the HKM round-caster, and the optimization was underpinned using CFD. The casting texture evaluation was analysed with the help of an Ultrasonic-Device and amazing features - achieved with Super Swirl - could be proved.
