PROCESS FOR THE HYDROTHERMAL HARDENING AND DRYING OF CSH BONDED SHAPED BODIES, AND DEVICE FOR CARRYING OUT THE PROCESS

摘要

A device for hardening and drying calcium silicate hydrate bonded shaped bodies, in the form of an autoclave (1), in the interior of which, on the bottom side, at least one live steam rail (10), which extends in the longitudinal direction, said support elements, which extend in the longitudinal direction and are arranged at a lateral distance from one another, for bearing elements, which accommodate the shaped blocks to be hardened and dried, are arranged, and if appropriate heat sources are provided in the region of the autoclave side walls, wherein (a) the lateral distance between the bearing elements and the shaped blocks is selected to be sufficiently large for there to be a flow channel (2d) between the shaped blocks, (b) a steam circulation device is present, by means of which, during circulation, the steam is substantially flushed through the flow channel (2d), (c) at least one upper steam rail for the circulation of steam being arranged above the flow channel. 1818 כ" ג בתמוז התש" ס - July 26, 2000
