[0002] Copper alloy profiles, including: copper rods, copper tubes and copper strips (copper plates), but the current method of producing copper alloy profiles has a traditional three-step method: melting ingredients - semi-continuous ingot casting - perforated hot extrusion, the disadvantages of this method It is a large investment in equipment, a large area occupied, a large processing loss, a large number of employees, and a low yield
In addition, in the production of copper alloy profiles by CIDC, due to the pull-stop-pull-stop operation method, not only the produced profiles are not smooth, but also there is contact and friction between the inner tube of the crystallizer and the copper alloy profiles, and the mold Disadvantages of short service life and easily broken profiles

The invention discloses a downward-drawing continuous casting device for a copper alloy profile. The device comprises a smelting furnace, a casting furnace, a molten liquid channel, a heating device, a crystallizer, a profile die, a profile die plug and an electromagnetic stirrer. The device is characterized in that the smelting furnace is quadrate; the capacity of the casting furnace is less than that of the smelting furnace; the smelting furnace is closely connected to the casting furnace and then is positioned on a furnace platform; the through molten metal channel is arranged at the bottom part of the casting furnace and toward the smelting furnace direction; the heating device is arranged on the molten metal channel; the profile die right above which the profile die plug is mounted is arranged at the bottom part of the frontend of the casting furnace; the crystallizer is mounted below the profile die, and the electromagnetic stirrer is mounted at the outside of the crystallizer. The device is simple in structure, low in energy consumption, and high in efficiency, can achieve the short-process production of the copper alloy, and makes outstanding real contributions for green processing and operation.
Description
technical field [0001] The invention relates to the technical field of copper alloy manufacturing, in particular to down-drawing continuous casting equipment for copper alloy profiles. Background technique [0002] Copper alloy profiles, including: copper rods, copper tubes and copper strips (copper plates), but the current method of producing copper alloy profiles has a traditional three-step method: melting ingredients - semi-continuous ingot casting - perforated hot extrusion, the disadvantages of this method It is a large investment in equipment, a large floor space, a large processing loss, a large number of employees, and a low yield. In addition, in the production of copper alloy profiles by CIDC, due to the pull-stop-pull-stop operation method, not only the produced profiles are not smooth, but also there is contact and friction between the inner tube of the crystallizer and the copper alloy profiles, and the mold The disadvantages of short service life and easy bre...
