Introduction High-alumina 1850°C monocast refractories

High-alumina 1850°C monocast refractories give furnaces, kilns and ladles a dense, seamless lining. The castable mixes with water and sets into one solid block with no joints. Moreover, the high alumina body keeps its strength at temperatures up to 1850°C. Workers pour, vibrate or trowel the material into any shape, so complex linings take less time. Factories in Bangladesh use it in steel furnaces, foundry ladles and heat treatment kilns. The low porosity blocks slag, molten metal and chemical attack. Besides that, the dense structure resists abrasion and thermal shock. Each 25 kg bag arrives in a moisture-proof pack, and astzbd delivers it across Bangladesh.

Frequently Asked Questions / FAQ High-alumina 1850°C monocast refractories

1. What temperature do High-alumina 1850°C monocast refractories handle?
   They handle service temperatures up to 1850°C.
2. How much water should I add?
   Add 4–6% water by weight. Mix until the castable flows evenly.
3. How long does the castable take to cure?
   The castable sets in 24 hours. Dry it slowly at 110°C before the first full firing.
4. Can I use it to repair an old lining?
   Yes. Clean the surface first, then cast the new layer against it.
5. How should I store the bags?
   Keep the bags in a dry, covered place away from moisture. Use them within 6 months.
