Abstract
A metal casting is heated using infrared energy by introducing the metal casting into a heating system with infrared emitters directed towards the casting, and activating at least a portion of the emitters. The heating system includes a heating chamber, a plurality of directional infrared emitters in the heating chamber, an optical temperature sensor directed towards a part location in the interior of the heating chamber, and a thermal shield that is movable between a deployed position and a retracted position, the thermal shield comprising an observation duct. The observation duct provides a line-of-sight path between the optical temperature sensor and the part location when the thermal shield is in the deployed position, and the thermal shield is between the plurality of infrared emitters and the part location when the thermal shield is in the deployed position.
