Self-flow Castables
Product introduction
According to the solid rheology theory and the actual service condition of refractory materials, PRCO developed high-tech self-flow castables (SFC). Without vibration, SFC can be degassed and leveled by gravity and thereby become compact.
These products have the following advantages: good flow ability, suitable setting time, labor-saving, high-strength, long service life, good insulation, and high temperature resistance, superior resistance to thermal shock and good erosion-corrosion resistance.
These products can be applied in all areas where applications require low cement, ultra-low cement and non-cement castables. The corundum based SFC is widely used in ladle bottoms, around the seating block areas and EAF roof. Both mullite-based SFC and alumina-based ones can be applied as the ladle and tundish safety linings. These products can also be installed by pumping. SFC are also available for reheat furnace applications.
