Claims

[Scope of utility model registration request]

A lance with a bent tip; A lance lifting means equipped with a run holder that removably holds the rear end of the lance; A lance lifting frame that slidably guides the lance lifting means; An inclination of the lance lifting frame. In the hot metal lance blowing device, the lance blowing device has: a traveling carriage on which the various lance means and a frame for raising and lowering the lance are mounted; is tiltable in a vertical plane including the frame, and blows the hot metal inside the pig iron mixing car with one lance by pointing the curved opening at the tip of the lance alternately toward the front and rear ends of the longitudinal direction inside the mixing car. This is a cow blowing device that can process the mixture.
