Recent developments on inductive measurement techniques for liquid metals

Wondrak, T.

There is a growing interest in determining the flow properties of metal or semiconductor melts, such as flow rate, flow structure and gas distribution. Typical applications are melt refining, continuous steel casting, silicon crystal growth or cooling of the receiver of a concentrated solar thermal power plant. However, the opaqueness prevents the use of well established optical methods. Additionally, the high temperatures (e. g. 1500°C for liquid steel or liquid silicon) and the corrosiveness of those fluids demand for contactless measurement techniques. By exploiting the high electrical conductivity of those melts inductive methods can be used. In this talk several inductive measurement techniques will be presented including transient eddy current flow meter, contactless inductive flow tomography and mutual inductance tomography. Additionally, a short overview about ultrasound techniques will be given which can be used to verify the inductive methods.
