Ceramic moulded body

Abstract

The invention relates to a ceramic moulded body, the surface of which is at least partly covered by a steel cladding, whereby the steel cladding is at least partly coated with a fire-resistant material on the surface thereof not covering the moulded body.

1 . Ceramic form ( 1 ), whose surface ( 9 ,  13 ,  15 ) is covered at least sectionally with a steel covering ( 5 ), where the steel covering ( 5 ) is covered, at least sectionally, in that part of its surface not covering the form ( 1 ), with a scale-inhibiting substance ( 7 ).  
     
     
         2 . Ceramic form ( 1 ) according to  claim 1 , as pouring spout for metal casting.  
     
     
         3 . Ceramic form ( 1 ) according to  claim 2 , as an interchangeable pouring spout.  
     
     
         4 . Ceramic form ( 1 ) according to  claim 1 , for a sliding value system.  
     
     
         5 . Ceramic form ( 1 ) according to  claim 1 , the steel covering ( 5 ) of which rests directly on the surface ( 13 ) of the ceramic form ( 1 ).  
     
     
         6 . Ceramic form ( 1 ) according to  claim 1 , the steel covering ( 5 ) of which is a sheet of steel.  
     
     
         7 . Ceramic form ( 1 ) according to  claim 1 , the steel covering ( 5 ) of which envelops the ceramic form ( 1 ) along its outer circumferential surface ( 13 ).  
     
     
         8 . Ceramic form ( 1 ) according to  claim 6 , the steel covering ( 5 ) of which envelops the ceramic form ( 1 ) under pre-stress tension.  
     
     
         9 . Ceramic form ( 1 ) according to  claim 1 , the scale-inhibiting substance of which is a metal or metallic compound.  
     
     
         10 . Ceramic form ( 1 ) according to  claim 1 , with a scale-inhibiting substance in the form of a sheet ( 7 ) or a layer applied to the steel covering ( 5 ).  
     
     
         11 . Ceramic form ( 1 ) according to  claim 1 , the scale-inhibiting substance of which consists of aluminum or an aluminum compound.  
     
     
         12 . Ceramic form ( 1 ) according to  claim 1 , the scale-inhibiting substance ( 7 ) of which is sprayed onto the steel covering ( 5 ).  
     
     
         13 . Ceramic form ( 1 ) according to  claim 1 , the scale-inhibiting substance ( 7 ) of which forms a gas-tight seal with respect to the covered surfaces of the steel covering ( 5 ).
