1. An apparatus for cooling a metal material, comprising:
a spray cooling unit for spraying a cooling medium to a surface of a metal material; and
a spraying amount control unit for adjusting a spraying amount of a cooling medium by adjusting a rate of passage of the cooling medium sprayed from the spray cooling unit to an edge region of the metal material,
wherein the spray cooling unit includes: a main chamber connected to a fluid supply line through which a cooling medium is supplied; and a spraying chamber installed on a front surface of the main chamber in multiple stages along a metal material, and including a spraying line through which a cooling medium is sprayed to the metal material, and
wherein the spraying amount control unit is formed of a breathable material to reduce the flow rate of the sprayed cooling medium by covering the both edge regions of the spraying chamber while rotating along the front surface of the spraying chamber.
