Abstract (en)
First, a melt is formed by heating a salt mixture (S101). Next, a mold for core molding is heated to a temperature higher than 0.52 × Tm and lower than 0.7 × Tm (S102). 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 (S103). A salt core for casting is molded by solidifying the melt inside the mold (S104).
