ABSTRACT:
A melting and casting furnace (1) for the production of directionally solidified or monocrystalline structures includes a housing (2) having a heating apparatus (3), and a cooling ring (4) disposed thereunder, as well as a cooling table (5) for the placement of a mold (6). Numerous radiation shields (8) in a heating zone in the housing, at a distance apart from one another and steer the heat rays onto a small area (A) in order to prevent direct radiation onto the metal already solidified or solidifying. In this manner the temperature gradient between the solidified and the molten can be kept great.
