1. Moulding process: Made of steel plate or hardwood board, the steel plate is coated with a release agent, and the wood board should be coated with a waterproof coating, without leakage, and have sufficient strength.
  2. Mixing process: Pour the insulation castable into the machine with a forced mixer, take out the additive bag, pour it together, dry mix for 2-3 minutes, add water for 3-5 minutes, and the amount of water added is 7.0-7.5%.
  3. Vibration process: The castable poured into the mold should be immediately vibrated in layers with a vibrating rod, and no vibration should be missed, vibrated and revived at the same position for a long time, so as to avoid segregation of the castable and the appearance of holes. The stirred refractory castable must be used up within 20-30 minutes after adding water, and the initial setting material should be discarded. Expansion joints are set according to the design.
  4. Curing process: After the surface of the castable is dry, it can reach 70% strength before the mold can be decomposed. The time for decomposing the mold is more than 24 hours, and the curing time is ensured to be more than 24 hours.
  5. Drying process: According to the different grades and thickness of castable lining and the weather conditions on site, the user must provide enough drying time to ensure that water will not break. The total baking time is stipulated to be ≥72 hours.
