  • Support and compression assemblies for curvilinear molten metal transfer device
    Patent number: 9561541
    Abstract: A curvilinear metal transfer device with support and compression assemblies that help maintain a constant force on the transfer device's metal outer casing and refractory as the outer casing and refractory expand and contract due to temperature fluctuations. In one embodiment, the support assemblies are configured to apply force to the refractory to keep the refractory in tension with the outer casing to suspend the refractory relative the outer casing. Also disclosed are clamp plates that help hold the refractory in place, and nested lids that cover the curvilinear metal transfer device.
