Tuyeres work in a very aggressive environment where they are exposed to the highest heat concentrated part of the blast furnace.
The tuyers are subjected to extreme temperatures, structural load, pig iron drops and abrasion from suspended particles. The capacity of the tuyeres to resist to all severe conditions is extremely vital for the furnace to reach a stable operation.
Hence, the steel industry is very demanding when selecting possible suppliers. Cecal is proud to be one of the leading companies to design and manufacture tuyeres for blast furnaces globally.
Cecal manufactures a wide variety of tuyeres, developed to achieve high performance according to the specific operation features for each furnace.
-Number of circuits: Single or double;
-Type of channels: Conventional, spiral or with coil;
-Possible coatings: Metal hard-facing, ceramic or refractory;
Cecal’s tuyeres comply with the most demanding technical requirements of operators and providers of blast furnaces.
The fabrication of the tuyeres can be according to drawings and specifications from the customer, or according to Cecal’s design, which is customized for each specific application.
