Support and compression assemblies for curvilinear molten metal transfer device

A curvilinear metal transfer device comprising:

• an outer casing comprising a curvilinear inner wall and a curvilinear outer wall, wherein the outer casing includes individual sections that are joined together at casing joints by a plurality of compression assemblies;
• and
• an inner refractory positioned within the outer casing and comprising a curvilinear inner wall and a curvilinear outer wall, wherein the inner refractory includes sections that abut one another at refractory joints, wherein the compression assemblies are compressible in circumferential directions to reduce gaps between the sections of the inner refractory, and wherein the compression assemblies are configured to account for lesser expansion of the curvilinear inner wall of the inner refractory than the curvilinear outer wall of the inner refractory.
