Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce a time for cooling steel slag to a prescribed temperature and discharge the steel slag while preventing steam explosion, when cooling the steel slag in an exclusive vessel with water.SOLUTION: Steel slag generated in a steel making process is discharged and subjected to water spray cooling in a cooling method of steel slag of the invention. An exclusive vessel 1 is prepared in advance in which a steel pipe 4 is arranged on an iron shell face 2 so that the upper end of the steel pipe 4 is located at a position of 0.80-0.93 (the lowest position of the iron shell face 2 in the vertical direction is 0 and the highest position thereof is 1), wherein the steel pipe 4 has open holes 3U, 3D at the upper end and lower end that communicate with each other.
