Embodiment Construction
[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0026] Such as figure 1 and figure 2 As shown, the jet agitator for mechanical stirring and desulfurization of molten iron of the present invention includes a rotating shaft 1 and a stirring blade 3 arranged at the lower end of the rotating shaft 1 and uniformly arranged along its circumference. The stirring blade 3 can be 3 to 6 pieces, rotating around Shaft 1 is evenly distributed circumferentially. The rotating shaft 1 is composed of a metal hollow shaft 1a and a refractory working lining 1b compounded outside the metal hollow shaft 1a, and an air-cooled pipe 2 is arranged in the inner cavity of the metal hollow shaft 1a. The lower end of the rotating shaft 1 is provided with an air injection channel 4 communicating with the air cooling tube 2 , and the air injection channel 4 is located between adjacent stirring blades 3 .
