Apparatus for producing reduced ceramic products, in particular roof tiles, in a tunnel kiln (furnace)

摘要

An apparatus for producing reduced ceramic products, in particular roof tiles (roofing tiles), in a tunnel kiln comprises, inter alia, spaces which are closed all around but open at the top, comprising cases in which the ceramic products are accommodated in one or more layers. The cases are carried on kiln carts (trucks) and each possess a sliding lid which can be moved to close the cases. In addition, the tunnel kiln is provided with a filling device which can be raised and lowered and is arranged above the cases and charges the cases with reducing agent. A stop which can be raised and lowered, and which is arranged at a distance from the filling device, grasps the sliding lids from behind and during the pushing procedure moves these on the cases in such a way that the cases are completely closed and closed reduction spaces are formed.
