Example Embodiment
[0021] Examples such as figure 1 As shown, a granulation device for liquid steel slag or iron slag includes a combined nozzle 1 composed of a tapered tube and a divergent tube, and a throat perpendicular to the combined nozzle 1 is arranged at the throat of the combined nozzle 1 The outer space of the combined nozzle 1 and the slag pipe 2 has a cooling airflow.
[0022] When molten steel slag or iron slag flows out of the pipeline, it is impacted and cooled by the high-speed airflow at the throat to form granulated slag. The granulated slag sprayed from the nozzle is mixed with the external cooling airflow, and further cooled to make it rapidly solidified.
[0023] In the above embodiment, such as figure 2 As shown, the combined nozzle can also be composed of a venturi 3.
[0024] In the above embodiment, such as image 3 As shown, the combined nozzle can also be constituted by the Rafar nozzle 4.
[0025] In the above embodiment, the arrangement of the slag pipe 2 on the periphe...
