FIELD: mechanics.
SUBSTANCE: invention relates to foundry engineering. The system consists of a down gate, horizontal ingate, slotted feeder and one or several head skimming gates connected to the ingate and slotted feeder. In periphery of each head skimming gate, there is a metal plate in front of the slotted feeder inlet. It is installed perpendicular or at an angle to the head skimming gate. The plate has a melting temperature, which is not more than the temperature of the melt being poured. The plate thickness is selected upon a condition that plate integrity is preserved until the moment of head is filled up with metal.
EFFECT: improved quality of mold and reduced number of defects by slag and sand inclusions.
