Twin roll casting (TRC) is an effective and therefor cost saving method for production of Mg sheet material. This is essential for widening the areas of application of magnesium especially in the automotive sector. Part of the ongoing project SubSEEMag which is focused on the substitution of rare-earth elements in Mg wrought alloys is the improvement of the TRC process. One problematic aspect of processing magnesium strip material in the TRC process is based on the temperature profile of the melt inside the tip. This could result in freezing of the melt inside the tip and its destruction. For resolving this problem various coated and non-coated ceramic materials were inspected regarding their thermal isolation capability and their durability in contact to molten Magnesium. For improving the flow behavior a new geometry of the tip was developed based on numerical simulations.
