Ceramic Welding for Coke Ovens

Fosbel has a range of ceramic welding powders, process machines and lances to accommodate a variety of applications. The selection of materials and machines for each repair is dependent upon location, size and type of repair.

Ceramic Welding Repair Facts:

  • Fosbel repairs are always carried out in hot ovens. All hot areas of the oven can be repaired by ceramic welding.

  • Heat is retained by insulating door panels.

  • Repair areas are thoroughly cleaned using specially designed heat resistant cleaning tools and/or abrasive blasting.

  • The ceramic weld process reconstructs the refractory back to its original state.

  • Gas tight welding repairs reduce energy loss and solve environmental issues.
     

Nano-Tec™ Ceramic Weld Powders

Fosbel initiated a research project to address ceramic welding repairs on older ovens that do not heat as well as designed.  In many cases, the cooler end flues do not generate enough heat to ensure a quality ceramic weld. This research project resulted in the next generation of ceramic welding powders.

Fosbel’s line of Nano-Tec™ materials exhibit greater yield and lower rebound, thus decreasing weld time and lowering the cost of repairs.

Nano-Tec™ materials exhibit nine times less inhale-able crystalline silica compared to standard ceramic welding materials.

Our new family of Nano-Tec™ powders are currently silica-based formulations which improve yield (up to 15%).

Controlled lab tests resulted in Nano-Tec™ S having a 54-60% better yield against standard silica material.

Nano-Tec™ S tested 4 times more abrasion resistant than a silica brick and 3 times more abrasion resistant than a typical silica weld mass.
