WATER COOLED MOLD FOR CONTINUOUS CASTING

PURPOSE:To prevent casting defect caused by insufficient cooling and uneven cooling by forming at least the face of a cooling metal in close contact with a mold of thin film, which can be deformed by water pressure and has good heat conductivity. CONSTITUTION:The molten metal is caused to continuously flow down into the mold 2 and cooled with each cooling metal 3. At this time, in each cooling metal, cooling water is supplied into a hollow part 8 from a cooling water supplying hole 5, and heat of the molten metal is absorbed by the mold 2 and further, heat of the mold 2 is absorbed by the cooling water in a hollow part 8 through a vessel 7 of the cooling metal 3, and cooling water conducting the heat is discharged from a cooling water discharging hole 6. The vessel 7 is manufactured of the metal having good heat conductivity and as the vessel 7 is formed to the thin film so as to receive the deformation by the water pressure of cooling water supplied into the hollow part 8, bulged and deformed by the cooling water in the hollow part 8 and the face in extra tight contact with side face of the mold 2 is formed. By this method, the uniform cooling action is given to the molten metal flowing down at uniform velocity in the mold 2.
