Abstract
The invention relates to a device for heating molten metal by the use of a heater that can be immersed into the molten metal. This immersion heater includes an outer cover formed of one or more materials resistant to the molten metal in which the immersion heater is to be used, and a heating element inside of the outer cover, where the heating element is protected from contacting the molten metal.
Claims93
A device comprising:
- a vessel for containing molten metal, the vessel having a length, a width, a top surface, a first chamber and a second chamber, and an inlet in the first chamber in fluid communication with the vessel;
- a plurality of immersion heaters being rectangular and positioned in line across the width of the vessel, each of the plurality of immersion heaters comprising an outer cover of material resistant to molten metal and a heating element inside of the outer cover, the heating element connectable to an energy source, the outer cover comprised of a material formulated to be resistant to the molten metal, wherein the outer cover protects the heating element from contacting the molten metal when the immersion heater is positioned in the molten metal;
- and
- wherein the plurality of immersion heaters divides the vessel into the first chamber and the second chamber.
