N2 - The production of wear-resistant and acid-resistant stone castings is restricted mainly to the products having simple configurations (tiles, pipes etc.). They have an open (exposed to the atmosphere) cast surface that forms under the action of the gravitational force (tiles) or a centrifugal force (pipes). This makes it possible to solve the problem of filling the mold with a viscous silicate melt simply by changing the location where the stream enters during the casting process. At the same time, removal of the solidified castings from the molds and their subsequent firing become easy. Prevention of the formation of bulk (volumetric) defects due to the occurrence of shrinkage and due to the presence of gases is one of the major problems. Shrinkage of the stone casting melts is a natural phenomenon that is related to volume reduction during the cooling or crystallization (solidification). Methods how to eliminate shrinkage are proposed, based on experimental results.
