Typical applications

Pre-cast blocks are then wherever dense bricks cannot be suitably pressed due to the complexity of the shape. In case of small quantities, pre-cast blocks are likewise preferred to dense bricks.

The composition and processing of the pre-cast blocks can be selected depending on the requirements, whether dried / annealed / fired, low-cement / cement-free, from fireclay to corundum, as well as from dense to insulating. In addition to the material combination, pre-formed shapes can be made of refractory castables according to the customers’ individual requirements. By means of sophisticated formwork technology and experienced mold builders, even the most complex shapes can be realized.


  • For example, in the glass industry
  • regenerator chambers
  • melting tanks
  • work tanks
  • forehearths
  • basins and glass processing
