Abstract
A method for producing a salt core includes a step A of adding a saturated sodium chloride aqueous solution to a sodium chloride crystal that is granular, to prepare a slurry mixed material of sodium chloride and water, a step B of subjecting the slurry mixed material to pressure molding to obtain a molded article, and a step C of drying the molded article to remove moisture.
Claims7
A method for producing a salt core, comprising:
- a step A of adding a saturated sodium chloride aqueous solution to a sodium chloride crystal that is granular, to prepare a slurry mixed material of sodium chloride and water, where an amount of saturated sodium chloride aqueous solution is Ma parts by mass or more with respect to 100 parts by mass of sodium chloride crystal;
- a step B of subjecting the slurry mixed material to pressure molding to obtain a molded article;
- and
- a step C of drying the molded article to remove moisture,
- wherein the Ma is determined based on a relationship between a mass of the saturated sodium chloride aqueous solution added with respect to 100 parts by mass of the sodium chloride crystal and a flow rate of a mixed material of sodium chloride and water when the mass added causes the flow rate to start increasing, found by increasing the mass added from 0 parts by mass.
