Abstract

In order to blow gases into hot chambers with fireproof linings and create a gas sink (6) with directional porosity, it is proposed that moulding plates should be used made from rolled green compacts permeated in their interior by gas through-flow ducts (3). The latter are produced during the rolling operation by rolling in or working in dimensionally stable foils of a material which can be melted out or burned out. Once the green compacts have been rolled, the foils are melted out or burned out.
