Document Type and Number:
Japanese Patent JP7376080
Kind Code:
B2
Abstract:
To enable a configuration regarding roles of a melting chamber in a melting holding furnace, with which selection can be made between dual roles of melting a treatment material and circulating molten metal and a role mainly of circulating molten metal.SOLUTION: A melting holding furnace of this invention comprises: a holding chamber 3 for molten metal; a melting chamber 1; an outward path 4 that delivers the molten metal out from the melting chamber to the holding chamber; a homeward path 6 that guides the molten metal from the holding chamber to the melting chamber; and a non-contact type stirrer 23 provided inside the melting chamber. The melting chamber includes, in addition to an outer peripheral wall 11 and an inner peripheral wall 13 provided with the non-contact type stirrer therein, a blockage wall 16 that partially blocks a section between the inner peripheral wall and outer peripheral wall, in which the blockage wall is detachably provided while holding a state in which the molten metal circulates through the outward path and the homeward path. In a case in which the blockage wall is removed, the melting chamber can exercise dual roles of melting a treatment material and circulating the molten metal by generating a vortex flow by stirring the molten metal in the melting chamber, and in a case in which the blockage wall is installed, the melting chamber can exercise a roll mainly of circulating the molten metal.SELECTED DRAWING: Figure 1
