Thermal launder for the transfer of white metal in a smelting furnace

Thermal launder that allows white metal (WM) or other molten material to be transported from a melting furnace to a converter furnace, or from a melting furnace to a transfer pot, keeping it in a molten state and conserving its viscosity throughout the route, which is composed of a structure (1) comprised of a cover (2) and a transport duct (3), which form, when said cover (2) is closed, the thermal launder itself. In the upper part of said cover (2), heating elements (4) are installed, surrounded by the upper insulation (5), which is covered by a structural housing (6), CHARACTERIZED in that said transport duct (3) is comprised of four elements arranged in series, which are defined by a transport layer (7), then a refractory layer (8), followed by an insulation layer (9) and a structural layer (10).
