Abstract
The binder coated refractories comprises the refractory aggregates and the solid-form coating layer which comprises the sugar group as the binder and which is provided to the surface of the refractory aggregates. According to this, the sugar group is used as the binder for bonding the refractory aggregates. Further, even if the sugar group is thermally decomposed, the sugar group emits the carbon dioxide and the water. Therefore, there is little likelihood of emitting the harmful gas. Therefore, it is possible to reduce the environmental pollution. Further, the sugar group is thermally decomposed easily. Therefore, it is possible to manufacture the casting mold having the good breaking property.
