ABSTRACT:
An insulating blanket is provided for dispensing an insulating particulate material onto the surface of a molten metal. This blanket comprises a bag containing the insulating particulate material, the bag having flattening means such that when the bag is filled with the particulate material, it maintains a substantially flat shape. The bag is formed of a material which will disintegrate upon contact with the molten metal, thereby allowing the particulate material to spread over the surface thereof.
