Liquid metal modeling of continuous steel casting – the LIMMCAST programme at HZDR

We present the new experimental facility LIMMCAST for modelling the continuous casting process of steel using the alloy SnBi at temperatures of 200-400°C. In addition, a smaller set-up Mini-LIMMCAST operates with the room-temperature liquid alloy GaInSn. First results will be presented covering the following phenomena: fully contactless electromagnetic tomography of the flow in the mould, mould flow monitoring by an array of ultrasonic sensors, analysis of the flow in the mould under the influence of an electromagnetic brake and the injection of argon bubbles through the stopper rod. Numerical simulations using ANSYS-CFX were performed which basically confirm the measuring results.
