Embodiment 2
[0029] The weight of liquid electric furnace steel slag is 500kg, the temperature is 1600°C, and its chemical composition (weight percentage) is as follows: CaO: 29.1%, MgO: 9.7%, SiO 2 :16.5%,Al 2 o 3 : 3.5%, FeO: 20.9%, MnO: 4.5%, free calcium oxide 6.3%, free magnesium oxide: 8.9%, other 0.6%. The steel slag flow rate is 0.1t / min, the gas pressure in the air cavity is 0.05MPa, and the air volume is 5m 3 / min; the angle between the spray panel and the horizontal direction is 55°; the angle between the second layer of nozzles and the normal line of the panel is 5°, after the steel slag is granulated according to the above process, the FeO phase in the steel slag disappears, and the content of free CaO and MgO is low. to 0.1%, while 2CaO·Fe 2 o 3 The phase increases significantly, the steel slag is granulated into balls, with a spinel structure, and the structure is stable.
[0030] The comparison of the appearance and composition of the steel slag processed by this metho...
