The PyroFast refractory system is designed around a two component technology incorporating a dry refractory aggregate mixed with a liquid binder. This material can be effectively mixed and placed on-site, working well for both casting and patching. After PyroFast 234 has fully cured, it has a maximum use temperature of 3100°F (1700°C).

This material is a unique phosphate-bonded high alumina refractory castable, recommended for use in aluminium applications where corrosion, thermal shock, alkali attack and high temperature are factors. Pyrotek technical specialists are available to assist in specifying the best materials for each use, applications and dryout procedures for PyroFast 234.

Advantages

• Fast mixing and setting
• Quick turnaround
• Inherently resistant to corrosion by molten aluminium alloys, without the use of non-wetting additives
• Thermal shock resistant
• Alkali resistant
• High temperature tolerance
• Bonds to most refractories, except unfired refractories, zirconia or nitride bonded SiC brick

Applications

• Melting and holding furnace “belly band,” lower sidewalls and hearths
• Furnace block (subhearth)
• Heated launder systems for continuous casting and foundry diecasting
• Transfer crucible linings, spouts
• Trough patching and repair
• Furnace ramps
• Furnace doors, lintels, sills and jambs
• Furnace charge / pump wells
