European project will reduce surface crack failure in continuous casting of steel

25 June, 2018

The RFCS project PMAPIA (Precipitation of Micro Alloy Particles in B and Mn alloyed steel grades and the InterAction between elements, segregation, and defects during continuous casting) coordinates by Swerea KIMAB. It’s a Europen project with a total budget of 2 million € and a project duration of 42 months.

The overall objective of PMAPIA is to reduce rejection and requirements for surface rework caused by cracking defects of continuously cast semis by investigating interactions between alloying elements and their effects on micro segregation and precipitation processes during continuous casting.

The specific objectives within this proposal aim to develop criteria for composition optimization, cooling conditions and strain levels to prevent formation of crack defects in semis during continuous casting of steel grades alloyed with Boron, Sulfur and Manganese, and their relationship with other micro-alloying elements.

The project is focused in three areas: industrial plant based investigation and as-cast semis characterisation, pilot plant / laboratory based research, and numerical simulation.
