Pyrotek Pyrocast AR PLUS Castable Refractory

Pyrocast AR Plus is a fused silica refractory castable inert to molten aluminum and its alloys. Parts cast from Pyrocast AR Plus are heat-treated to ensure that free and combined water are removed. Because Pyrocast AR Plus is lighter than molten aluminum, it floats, minimizing the potential for refractory inclusions.

Applications

• Hot-Top table sections
• Transfer & stub troughs
• Launder linings
• Filter boxes
• Sheet ingot spouts
• Control pins
• Furnace tubes

Advantages

• Thermal shock resistance
• High erosion resistance
• High service temperature
• Smooth cast surface
• Dimensionally stable
• Preheating unnecessary
• Easily cleaned
• Non-wetting
