Pressure slip - a casting apparatus and method for the casting of a molded article

摘要

The present invention relates to a pressure slip - casting device and a method for casting a guide member, which / s is designed, by means of slip casting make a molded article, the bimodal is composed of granular and refractory material with fine components (k1) with first grain sizes (k1) in the range of 0,01 μm up to 100 μm and with coarse fractions (k2) with second grain sizes (k2) in the region of 100 μm to 10 mm. After the sintering of the shaped part can thus be a refractory shaped part in a simple manner be provided.For this purpose is a part of the apparatus in a pressure vessel (5) provided slip (s) by means of a pressure medium (g) from the pressure vessel (5) by means of the outflow line or conduit (7) in the casting chamber (8) is conveyed. In this case, preferably an outflow line or conduit (7) dimensioned or the pressure is so selected that the slip (s), with at most negligible shear forces acting on it by the outflow line or conduit (7) is conveyed.
