Abstract
A hot-top is disclosed that continuously casts an ingot by pouring molten metal down into a cylindrical space in a continuous casting mold from a molten metal flow-down port. The inner shape of a flow-down port forming part corresponds to the inner shape of a cylindrical space forming part. The hot-top forms an annular groove about the molten metal flow-down port, and has a barrier between the annular groove and the flow-down port.
