Nearly 80 years
of expertise and
of innovation TRB
Every year, we produce 20,000 t of this organo-mineral material (ECOTAP), which is essential for casting molten metal. Our refractory aggregates are selected according to operating conditions, and include corundum, bauxite or quartz, among others. They are complemented by special additives such as Silicon Carbide or Carbonaceous materials to excel in all circumstances.
Every year, TRB produces 20,000 tonnes of ECOTAP organo-mineral Tapehole Clay, essential for sealing tapholes. Our formulations are based on a rigorous selection of refractory aggregates adapted to operating conditions(corundum, bauxite, quartz), enriched with specific additives such as silicon carbide or carbonaceous materials, to guarantee optimum performance in all configurations.
Thanks to this expertise, TRB now seals more than 40 blast furnaces in over 25 countries, with capacities ranging from 1,000 to 13,000 tonnes per day. Our solutions help extend the life of sensitive areas, stabilize production and reduce operating costs. A forerunner in innovation, TRB was also one of the first players to develop more environmentally-friendly Tapehole Clay formulations.
