ABSTRACT:
For the purpose of pouring a stepwise advanced casting mould consisting of identical, flaskless mould parts having vertical joints at which there are provided inlets or chutes extending from the top surface of the mould to its casting cavities, use is made of a pouring tundish having a slitlike bottom outlet adapted to cover three or more inlets temporarily blocked by an obstruction. After an additive has been fed to the tundish this is being filled with the necessary amount of molten iron which prior to removal of the obstruction gets the opportunity of being merged uniformly with the additive, and possible slag products may at the same time rise to the surface. The pouring tundish may meanwhile be advanced one or more steps together with the casting mould while being in firm contact with its top face. After the pouring step has finished the pouring tundish may be disengaged from the casting mould and be returned past the starting position to be fed with additive, and is subsequently ready for a new operation. For a given cycle time of the plant, the period available for the pouring operation may be considerably extended, thereby entailing quality improvements in the produced castings.
