Molten Metal Handling Device Heating System

摘要

Disclosed is a heating system for molten metal handling devices, examples of which are troughs, launders and other vessels. The heating system may include a refractory containment body, heater assembly, a containment shell and a thermal inducing interface between the heater assemblies and the containment shell and/or refractory body.

主权项

1. A molten metal handling device, comprising:
an outer casing with a bottom and two side walls generally defining an inner cavity; one or more heater assemblies within the outer casing, each heater assembly comprising:
a heater assembly body with an inward facing surface, the inward facing surface including recesses;heater coils within the heater assembly body spaced apart from the inward facing surface of the heater assembly body; a castable refractory body defining a molten metal carrying cavity with a bottom wall, a first side wall and a second side wall, the castable refractory body abutting the one or more heater assemblies; and wherein thermal inducing cement is disposed within the recesses in the inward facing surface of the heater assembly body, facilitating conductive heat transfer from the heater coils through the thermal inducing cement to the refractory body.
