PROBLEM TO BE SOLVED: To provide a production method of a raw material for sintering, allowing for easy and inexpensive production of steel slag particles strong enough to withstand rolling motion in a granulation line for granulating a raw material other than steel slag.SOLUTION: The production method of a raw material for sintering is provided for producing the raw material for sintering by dividing a raw material of blast furnace sinter into steel slag and a raw material other than steel slag and granulating them separately. The steel slag is mixed with water and granulated to make particles. The granulated particles of the steel slag is then charged to a granulation line for the raw material other than steel slag and the surface of the particles of the steel slag is attached by or coated with the raw material other than steel slag. The particles of the steel slag is left wet and cured for preferably 5 days or more before being charged to the granulation line. |
