Abstract
A method for the insulation of a hot metallic material which is heated for hot working is described, which comprises applying a mixture of acidic aluminum phosphate, e.g., aluminum hydrogenorthophosphate, a multivalent metal oxide, hydroxide, silicate or carbonate powder, and water onto the surface of the hot metallic material and allowing the mixture to be heated by the heat of the hot metallic material to convert it to a porous hardened material. The porous hardened material acts as an insulating coating layer for the hot metallic material, permitting hot working in an insulated state for a long period of time.
