Title:
CASTING DEVICE FOR INGOT
Document Type and Number:
WIPO Patent Application WO/2004/098812
Kind Code:
A1
Abstract:
[PROBLEMS] To provide a casting device capable of reducing defects such as macro segregation and shrinkage cavity resulting from such a flow that a convection loop is formed due to a difference in density between the solid and liquid phases of dendrite in a solid/liquid coexisting phase ranging from solidifying riser to the bottom part of a mold in manufacturing an ingot represented by a large-sized steel lump and also increasing the yielding of products, whereby increasing productivity and contributing to the improvement of environment by a reduction in energy. [MEANS FOR SOLVING PROBLEMS] A partition plate for separating the convection loop and reducing flow velocity is disposed in a boundary between a riser and the mold in the casting device formed of the riser and the mold. A space (through hole) allowing the supply of molten metal from a riser part to a product part is formed in the partition plate.
