VESSEL FOR CONTAINING MOLTEN METAL AND SYSTEM FOR CONTAINING MOLTEN METAL

Japanese Patent JP2017030052

A

SOLUTION: The vessel comprises: a refractory liner 12 having at least two refractory liner units 14, 15 with a joint 25 therebetween, the units 14, 15 each having an exterior surface and a metal-contacting interior surface; a housing 20 at least partially surrounding the exterior surfaces of the refractory liner units 14, 15 with a gap present between the exterior surfaces and the housing 20; and molten metal confinement elements 35, 36, impenetrable by molten metal, the molten metal confinement elements being positioned on opposite sides of the joint 25 within the gap, at least below a horizontal level corresponding to a maximum working height of the molten metal held, to partition the gap into a molten metal confinement region and another region. The refractory liner 12 may have a different thermal conductivity.EFFECT: The vessel can retain in the gap a device such as a heating element vulnerable to contact with the molten metal. In addition, the vessel maximizes heat penetration into the molten metal from the heating element, but minimizes heat loss at the ends of the refractory liner 12.SELECTED DRAWING: Figure 1
