Abstract
A heat shield for a casting furnace consists of at least two elements slidably mounted in the furnace. The elements are generally planar in shape and extend between heating and cooling zones to provide the requisite heat insulation characteristics. The heat shield elements are movable in a direction generally parallel to their plane which extends generally perpendicularly to the path of movement of the mold from the heating zone into the cooling zone. Each of the heat shield elements consists of a generally planar, substantially rigid portion slidably mounted in the furnace and a generally planar second portion formed of a flexible refractory material. Distal edges of the second portions may overlap each other and may define an opening, the contour of which closely approximates that of the cross sectional contour of the mold.
