ABSTRACT:
A blanket powder for covering a molten metal bath in order to prevent oxidation and to provide heat insulation contains, in addition to the ash of cereal hulls, approximately 5 to 50% by weight of non-calcined cereal hulls. The powder can thus be transported and handled without any attendant danger of contaminating dust formation and has enhanced heat-insulating power.
