In a method for producing a salt core for casting formed by a molten salt made of a salt mixture containing sodium salt, first, a melt is formed by heating a salt mixture. Next, a mold for core molding is heated to a temperature higher than about 0.52×Tm and lower than about 0.7×Tm. Note that Tm represents the liquidus temperature of the salt mixture as an absolute temperature (K). Then, the melt is poured under pressure into the mold heated as described above. A salt core for casting is molded by solidifying the melt inside the mold. |
