Electromagnetic conveyer trough for the conveyance of molten metals
First Claim
1. In an electromagnetic conveying trough for conveying molten metals with a trough body extending in the direction of conveyance and lined with a fire-resistant lining, an inductor extending in the trough body along the direction of conveyance for producing a travelling electromagnetic field, said inductor including a grooved, laminated package with the grooves running transverse to the direction of conveyance and defining teeth, a coil winding disposed about each of said teeth and adapted for connection to a source of electrical potential, and coolant pipe lines extending in said grooves, the improvement wherein said pipe lines extend coaxially with respect to each said winding so as to form a separate and distinct unit with said winding, and wherein said electromagnetic conveying trough comprises coolant supply and discharge means for individually supplying coolant to said pipe lines in each of said separate and distinct units so that each of said units operates and may be replaced independently of the other of said units.

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.
