PROBLEM TO BE SOLVED: To adjust properties such as the particle size, strength and shape of slag. ;SOLUTION: Molten slag discharged from a combustion melting furnace is cooled to produce a solid slag and the cooling speed of the molten slag 20 is controlled to adjust the properties of the solid slag. In other words, when the cooling speed of the molten slag 20 is high, a large temperature difference is generated between the surface and the inside of a slag mass and a fine cracking is generated by the resulting heat impact. As a result, a relatively fine slag is formed with an angular shape and a smaller strength. When the slag is cooled slowly, a dense slag with a relatively large particle size, a round shape and a higher strength in obtained. So, an inclined plate 12 is arranged below a slag discharge port 5 of the combustion melting furnace 1 and a water infection nozzle 13 for infecting water is provided on the top surface of the inclined plate 12 to inject water to the molten slag 20 in the course of dropping. The degree of injection is controlled to adjust the propertils such as particle size, strength and shape of the slag.;COPYRIGHT: (C)1998,JPO
