Abstract

A packing material for refractory capable of restraining the deterioration of working environment since there is generated no smoke and foul smell even if used for setting preheated submerged nozzles or long nozzles, allowing easy visual observation of fitting operation, and maintaining the packing material deformation suppression performance. A packing material for refractory of the present invention is characterized in that a part or the whole surface of a packing base material for refractory formed from inorganic refractory powder, inorganic and/or organic fibrous raw material, and being agents and/or various types of additives is covered with a metal foil. This packing material may be used together with an inorganic paint or ceramic fiber sheet, and when so used, the metal foil is to be applied to the outermost surface thereof.
