Castable with plasticity

     Castable with plasticity for heating furnace are made by adopting a special binding system to have both good workability by casting and viscoplasticity which facilitates the absorption of thermal stress, so that the products have good thermal shock resistance and spalling resistance and are suitable for various areas of heating furnace.
