<p>The device for introducing metal scrap in a molten metal, comprises a heat-resistant lined cylindrical shaft (2) for injecting the metal scrap, a molten inlet (6) directed tangential to the shaft in a shaft base (3), a conducting surface outstandingly rising from inlet for the molten metal flowed in the shaft, and a concentric molten outlet (4) in the base. The shaft base forms a cone falling away from the outlet. The cone of the base forms the conducting surface and has an opening angle of 90[deg] . The inlet laterally passes to a radial outlet channel (5) subsequent to the axial outlet.

The shaft base forms a cone falling away from the outlet. The cone of the base forms the conducting surface and has an opening angle of 90[deg] . The inlet opens in the middle third level of the cone-shaped base and laterally passes to a radial outlet channel (5) subsequent to the axial outlet. A discharge aperture locked by a plug is intended on the side of the outlet opposite to the outlet channel.</p> |
