Tread Reactor

Saint-Gobain Performance Ceramics & Refractories is a global supplier of refractory solutions, specializing in all major carbon black technologies.


The commissioning process begins with the furnace operator specifying the operating conditions required to produce the grade of black desired.


Key factors such as reactor technologies, temperatures, geometries, fuel source(s) and feed source(s) will determine the solution offered.


Operating conditions vary by furnace zone, with different zones posing specific challenges in terms of atmosphere (oxidizing or reducing), gas velocities, chemical interactions, and temperature fluctuations (thermal shock).


Saint-Gobain Performance Ceramics & Refractories works closely with furnace operators to provide refractory solutions that meet the performance and cost goals of the operator. Lining solutions are also customized by material form and grade.
