Abstract
Electromagnetic helical pump for high-temperature transportation of molten metal, comprising an explicit-pole or implicit-pole inductor exciting a rotating magnetic field (RMF), and a helical channel consisting of a thick-wall ceramic pipe with a quick-change helical core made of graphite or graphitized carbon. The pump can be used for transportation and batching of molten aluminum, magnesium, copper, etc. and their alloys.
