Molding device for continuous casting with stirring unit

摘要

A molding device includes a mold that forms a casting by cooling received melt, and a stirring unit that applies a magnetic field to the melt in the mold and allows a current to flow in the melt. The mold forms a vertical casting space that includes an inlet into which the melt flows and an outlet from which a product is taken. A transition plate is disposed at the mold space inlet. The melt can flow into the casting space from a hole in the transition plate. The stirring unit includes a magnetic field unit making lines of magnetic force vertically run into the casting space, and a first electrode at the inlet side and a second electrode at the outlet side that can flow current through the melt in the casting space, and generate an electromagnetic force by making the flowing current cross the lines of magnetic force.

主权项

1. A molding device for continuous casting with a stirrer, the molding device from which a solid-phase casting can be taken out by cooling of a melt of a conductive material, the molding device comprising:
a mold that forms a casting by cooling the melt; and the stirrer that applies a magnetic field to the melt present in the mold and allows a current to flow in the melt in this state, wherein the mold includes a cylindrical mold body that is vertically provided, a central portion of the mold body forms a vertical casting space that includes an upper inlet into which the melt flows and a lower outlet from which a product is taken out, a transition plate body, which has a ring shape and functions as a transition plate, is disposed at the inlet of the casting space, the melt is allowed to flow into the casting space from a hole that is formed at a central portion of the transition plate body, and the stirrer includes
an upper magnet that includes a permanent magnet body provided above a bottom plate of the transition plate body with the bottom plate interposed therebetween and making lines of magnetic force vertically run into the casting space, anda pair of electrodes that allow the current to flow through the melt when the melt is contained in the casting space, generate an electromagnetic force by making the flowing current cross the lines of magnetic force, and include a first electrode provided at the inlet side and a second electrode provided at the outlet side.
