The invention proposes a copper smelting insulation chute device which comprises a steel structure foundation in the shape of an isosceles trapezoid, masonry layers built by refractory materials and high-alumina bricks on both sides and bottom of the steel structure foundation, U-shaped prefabricated parts arranged on the masonry layers, packing layers formed by packing ramming materials into gaps between the prefabricated parts and the masonry layers, cover plates covering both sides of a chute, and natural gas burner bushings inserted into the round holes in the centers of the cover plates. The copper smelting insulation chute device proposed by the invention guarantees the casting quality of anode plates and the operating rate of disc casting machines, increases the yield, simultaneously reduces fuel consumption, and decreases temperature loss in the flow and transmission process of copper water. Therefore, the casting quality of the anode plates is increased.
