Pressed Carbonaceous Or Carbon-bonded Fireproof Aluminum Oxide Products, and Method for Producing Same

The invention relates to pressed carbonaceous or carbon-bonded fireproof aluminum oxide products, and to a method for producing same. The fireproof products according to the invention are used, for example, as unitary plugs, immersion castings, and cauldron distribution pipes used for casting metals, particularly for casting steel. The fireproof products are made of pressed compounds made of a mixture of 50 to 70% by weight, preferably 50 to 60% by weight of aluminum oxide, 20 to 30% by weight of carbon carriers having a high carbon content, 4 to 12% by weight of carbonaceous binders, 2 to 7% by weight of finely pulverized metals or alloys based on silicon, 1 to 4% by weight of finely ground flow agents, 2 to 7% by weight of fine silicon dioxide and further oxides and/or non-oxides, except for primary silicon carbide, wherein the surface of the fireproof products produced from said pressed compound is implemented in the form of a self-glaze.
