Bubble Alumina Castable Refractory 5kg

Description

The Bubble Alumina Castable Refractory 5kg is a low density refractory mixture with excellent insulation properties. It is capable of withstanding temperatures in excess of 1600 °C and can be cast into different shapes/sizes.

5 kg makes a total volume of approximately 5 L

For high heat applications we recommend a 50 mm wall thickness.

Included items:

• 3 kg bubble alumina
• 1 kg A600
• 1 kg air separated fireclay

Instructions:

1. Combine included items in a ratio by weight of 3:1:1 (bubble alumina:A600:fireclay)
2. Add water to thoroughly wet mixture to a stiff consistency
3. Pour into form and gently tamp down
4. Drying can be accelerated by heating. On first firing start with a short duration of low heat to ensure the refractory is thoroughly dry
