  • Feeding a mold for continuous casting of metal
    Patent number: 4751955
    Abstract: The utilization of a feeder immersion type pipe for continuous casting is avoided through an antechamber-like feeder vessel on top of the mold for continuous casting, having a short extension that reaches into the mold cavity and defines a step towards the wall proper from which steel flows in widening cross section to directly form the casting strand. Casting extraction is enhanced by feeding appropriate material, either fluid or a foil, into the space of the mold cavity immediately underneath this step.
