Process for cooling stainless steel slag by wet method

The invention discloses a process for cooling stainless steel slag by a wet method. The process comprises the following steps of: cooling naturally for 20 to 24 hours on a cooling station after electric furnace mother solution slag is conveyed from a field; spraying for cooling for 4 to 6 hours, and controlling a slag surface, so that water is not accumulated on the slag surface; standing for 3 to 4 hours, when the maximum temperature of the walls of slag tanks is lower than 120 DEG C and the temperature of an inner core of the steel slag is lower than 300 DEG C, turning the slag over in a slag box, keeping dried in the slag box, and paving by using the massive slag; crushing the turned massive steel slag, wherein massive materials of which the diameter is smaller than 200 millimeters are taken as tank filling materials; transferring the tank filling materials into empty slag tanks to fill up the tank, wherein 3 to 5 tons of tank filling materials are added into each empty slag tank; and ...
