EFFECT OF STEEL FIBERS ON REFRACTORY CASTABLES

Journal of Engineering, 2002
Reinforcement of refractory castables with steel fibers improves their strength for cracking and spalling and expands the service life. The results show that raising the temperature from 700°C to 900°C causes an increase in porosityand decrease in ...

Mullite macro-needles for reinforcement of refractory castables

Cerâmica, 2022
Ceramic macro-needles incorporation as reinforcement in commercial refractory castable was studied. Ceramic macro-needles (Ø2x20 mm) were made from kaolinite clay and gibbsite to obtain mullite as the main crystalline phase.
