REFRACTORY SLURRY OF REDUCING CARBON PICKUP IN LOST FOAM CASTING, FOAM PATTERN AND PROCESSES FOR MANUFACTURING AND USING THE SAME

摘要

Refractory slurry for use in coating a foam cluster to provide a foam pattern for lost foam casting is provided. The slurry includes a catalyst capable of catalyzing reactions for vaporizing the foam cluster. A foam pattern with a refractory coating including the catalyst and processes for preparing the foam pattern and using the foam pattern are also provided.
