ABSTRACT:
The device (1) according to the invention achieves a homogeneous, protective and insulating covering layer on the top layer of a casting ladle containing molten steel. It comprises a fixed part from which a cover wiht scrapers (21, 22) is suspended, and a rotating part (2) fitted below the scrapers (21, 22). The rotating part (2) comprises a series of troughs (12) which are uniformly distributed around a central shaft (10). The troughs (12) have a radially widening slit in the direction away from the central shaft (10). Through the rotating movement of the rotating part (2) and the levelling action of the fixed scrapers (21, 22), the bulk material is uniformly distributed over the troughs (12) of the distribution bin. A rising and falling cover (4) makes it possible to process varying volumes of bulk material.
