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 ...
