Abstract

PURPOSE:To obtain granular expanded slag of a uniform diameter when molten slag is crushed by rapid cooling with water, by regulating the diameter of molten slag outflow holes to a prescribed value so that flows of molten slag are made thin and allowed to fall in drops. CONSTITUTION:A nozzle plate 4 having holes 6 of 3-80mm<2> diameter is prepd. Molten slag A produced in a blast furnace, etc., is passed through the nozzle plate 4 to form flows 8 of drops of the molten slag A. The flows 8 are allowed to fall into water 11 and the molten slag A is crushed by rapid cooling to obtain expanded slag B.
