PROBLEM TO BE SOLVED: To provide an apparatus for cooling treatment of molten slag by which thick slag solidified products suited for obtaining slag products such as coarse aggregate or the like can be produced. SOLUTION: In the apparatus, there are provided a pair of cooling drums 1 whose outer peripheral portions opposing each other have upward rotational direction, weirs 2 are provided above the pair of cooling drums 1 respectively, a slag reservoir A is formed between the upper outer peripheral surfaces of the pair of cooling drums 1 and the pair of weirs 2, and openings 3 through which the molten slag in the slag reservoir A can be extruded are formed between each weir 2 and each cooling drum 1. Appropriately cooled thick slag can be extruded from the openings 3 because the residence time of the molten slag in the slag reservoir A can be extended and the cooling of the molten slag can be effectively accelerated.
