摘要:
The object of the invention is to provide carbon-containing refractories which give off little decomposition gas having an offensive odor, exhibit excellent spalling resistance, and are equal or superior in kneading properties and molding properties to the refractories containing a phenolic resin as a binder; and a process for producing the same. To accomplish the object, the invention is characterized by replacing a conventionally employed phenolic resin binder with saccharified starch and/or reduced saccharified starch, a binder containing 40% to 80% by weight of saccharified starch and/or reduced saccharified starch and 20% to 60% by weight of water, or a binder containing 40% to 80% by weight of saccharified starch and/or reduced saccharified starch, 1% to 25% by weight of water, and 5% to 50% by weight of an alcohol having a boiling point of not lower than 80.degree. C.
