Brief description of the drawings
Fig. 1 is structural representation of the invention；
Fig. 2 is a-a sectional views in Fig. 1；
Fig. 3 is b-b sectional views in Fig. 1；
In figure：1 nebulizer body, 2 air inlets, 3 air slots, 4 molten steel leak, 5 protective cases, 6, water inlet, 7 guiding gutters, 8 gas
Stream, 9 current, 10 ring-crack ventilation air stream outlets, 11 water atomizing nozzles.
Specific embodiment
Below in conjunction with accompanying drawing, technical scheme is clearly and completely described.
Embodiment 1
As Figure 1-3, a kind of water-gas combined powder by atomization device, including nebulizer body 1, the nebulizer body is provided with steel
Liquid leak 4, air inlet 2, air slot 3, gas outlet, water inlet 6, guiding gutter 7 and 6 water atomizing nozzles 11；Molten steel leak and mist
Resistant to elevated temperatures protective case 5 is provided between change device main body；The air slot and guiding gutter are annular groove.The air slot and air inlet
Mouth is connected, and the gas outlet is connected with air slot；The guiding gutter is connected with water inlet, the water atomizing nozzle with lead
Tank is connected.The gas outlet is the ring-crack ventilation air stream outlet 10 for gradually drawing in, and 6 water atomizing nozzles annular is uniform,
The injection line focus of the gas outlet and water atomizing nozzle is located on the center line of molten steel leak, and gas outlet injection line focus
Higher than the injection line focus that water atomization is exported.
