ABSTRACT:
An electromagnetic conveying trough for conveying molten metals with a trough body extending in the direction of conveyance and lined with a fireproof lining and an inductor for producing a travelling electromagnetic field and formed as a grooved laminated package, the transversely extending grooves defining teeth about which individual coil windings are wrapped. In order to replace the inductor below a molten metal breakthrough without removing all of the lining, the coolant pipes are formed coaxial with each winding as a unit with separate coolant connections to each such unit.
