Device for obliquely dragging and successively solidifying wide thin copper and copper alloy plates and strips

The utility model relates to a device for obliquely dragging and successively solidifying wide thin copper and copper alloy plates and strips. By the directional solidification method, wide thin copper and copper alloy plates and strips are downwardly and obliquely dragged at an angle of 30-60 degrees, cooled in an immersed manner, and successively and directionally solidified and casted. The device comprises a furnace, a base, a metallic solution high-temperature zone, a metal preheating zone, a metal storage zone, a storage valve, a furnace cover and a heating element, wherein the metallic solution high-temperature zone is communicated with a mould. A high-temperature metallic solution filtering throttle valve is arranged on a solution guiding pipe. A mould heating element is arranged in a longitudinal furnace, which is equipped with a longitudinal furnace cover with an opening. A cooling guiding roller, disposed at the opening, is inclined downwardly at an angle of 30-60 degrees. A thin plate dummy device
