Used for insulation and heat preservation of the ladle walls in the operation of cast iron and cast steel, to prevent the cooling of molten iron (steel).
Utilizing advanced aerogel technology and specialized production processes, this material offers fast construction, rapid setting, high solidification strength, and excellent insulation properties.
The product is in a dry powder form with a long shelf life. Mix 50 kg of dry powder with 10 kg of mixed liquid and stir evenly during construction. The mixed material has a paste-like consistency. After cleaning the floating ash and adhered slag from the inner wall of the iron (steel) water package shell, apply the coating. Depending on the insulation requirements, the coating thickness should reach 10-20 mm. Apply from the bottom up, or invert the ladle and apply half of the package wall at a time. Once the coating layer shows some strength, flip the ladle and apply to the other half of the package wall.
1.It is recommended to use the opened insulation coating completely at one time.
2.Do not reuse mixed but unused coating; dispose of it directly.
3.After construction is complete, let the ladle stand at room temperature for at least 6 hours, then observe if the required strength has been achieved before proceeding with masonry work or castable pouring.
