Ceramic Welding

Fosbel's Ceramic Welding repair and maintenance program allows nonferrous metal producers to restore furnace linings to the original integrity of the refractory located in high wear areas without shutdown. Refractory restoration can be achieved at operating temperature. Furnaces repaired include: 

  • Melting and Holding Furnaces
  • Mearz Furnaces
  • Copper Converters, Reactors, and Anode Furnaces
  • Flash Furnaces

Any refractory type can be matched with a compatible Ceramic Welding material. The properties of the weld repair are matched to the original refractory.

Fosbel provides a superior gunning service, including a range of Fosgun gunning materials developed for numerous applications. The repair is carried out by trained technicians utilizing proven techniques resulting in a dense, smooth repair with documented longevity and durability.
