Self-flow Castables

According to the solid rheology theory and the actual service condition of refractory, Horton has developed the high-tech self-flow castables (SFC) in China. Without vibration, SFC will be degassed and leveled by gravity and thereby become compact.

The products show the features of good flowability, suitable setting time, labor-saving, high-strength, long service life, good insulation, high temperature resistance, superior resistance to thermal shock resistance, erosion-corrosion.

The products have been renowned as the fourth generation castables, which can be applied in all applications where low cement, ultra-low cement and no cement castables are applied. Corundum based SFC is suitable for the ladle bottom, around the seating block, gap fitting of EAF roof. Both mullite-based SFC and alumina-based ones can be applied for the permanent lining of ladle and tundish. SFC can also be installed by machine.
