Огнеупорная смесь DURACON 32

LCF 798A is an andalusite-based, low moisture castable designed for ferrous and non-ferrous refractory applications. This product is well suited for use in molten metal contact applications; such as tundish linings, ladle linings, launder systems and non-ferrous channel furnace uppercases. LCF 798A is also ideal for refractory shapes, covers, combustion systems, heat treatment furnaces and other heat containment applications. The excellent thermal shock resistance of the andalusite aggregate makes this an excellent material to pre-cast burner blocks. This formula is not for pumping; use LCF798A PUMP for that requirement.

This product offers the following benefits and features:
• excellent volume stability;
• organic fiber addition to minimize dryout time;
• outstanding thermal shock resistance.
