Title: Ragnhild Elisabeth Aune: Innovator in Metal Filtration Technology

Introduction

Ragnhild Elisabeth Aune is a notable inventor based in Stockholm, Sweden. She has made significant contributions to the field of metal filtration technology, particularly through her innovative patent that addresses the challenges of solid inclusions in liquid metal.

Latest Patents

Aune holds a patent for an "Apparatus and method for priming a molten metal filter." This invention describes an effective method for priming a non-electrically conductive filter designed to remove solid inclusions from liquid metal. The apparatus features a ceramic filter media surrounded by a low-frequency induction coil, which enhances the heating of any metal frozen onto or within the pores of the filter element. The design also generates Lorentz forces that help heated metal impinge on the filter's upper surface, improving the priming action. Once primed, the filter can be reheated and reused during multiple batch tapping sequences.
