Atomizer flow guide pipe assembly and atomizer

The atomizer flow guide pipe assembly comprises a flow guide pipe which is provided with an inlet for guiding in molten metal from a tundish and an outlet for guiding out the molten metal; the current generating unit is provided with two groups of electrodes, and the two groups of electrodes are both mounted on the inner wall of the flow guide pipe, so that when the molten metal flows through the flow guide pipe, the two groups of electrodes are conducted, and current flowing through the molten metal is formed between the two groups of electrodes, so that the molten metal is heated spontaneously; the magnetic field generating unit is used for generating a magnetic field, and the magnetic field fully or partially covers the area where the molten metal flows through in the flow guide pipe; the current direction, the magnetic field direction and the flow direction of the molten metal in the flow guide pipe are perpendicular to one another, so that the molten metal flowing in the flow guide pipe has Lorentz force
