Abstract
A process for casting castings in which a casting mold is provided, the casting mold is enclosed in a housing, forming a filling space between at least one inner surface section of the housing and an associated outer surface section of the casting mold, the filling space is filled with a pourable filling material having a bulk density that allows gas to flow through the filling material after the filling of the filling space, and a metal melt is poured into the casting mold. The casting mold radiates heat as a result of the heat input caused by the metal melt, and as a result of the heat input caused by the metal melt, the binder begins to evaporate and burn, no longer binding the molding material, and the casting mold disintegrates into fragments. The filling material has a temperature of less than 100° C. when filled into the filling space.
