The invention discloses a technology for producing a single-crystal conductive copper rod with an upward continuous casting method. The technology comprises steps as follows: an electrolytic copper raw material is put in a closed mixing melting furnace for melting, aluminum-antimony alloy powder, europium oxide powder and beryllium-aluminum alloy powder are added to a molten copper liquid, nitrogen and carbon monoxide mixed gas is introduced into the closed mixing melting furnace through a ventilation inlet in the bottom of the closed mixing melting furnace, and the mixed gas is discharged from a ventilation outlet in the top of the closed mixing melting furnace; a molten mixture is transferred into an upward continuous casting melting furnace and is enabled to enter an upward continuous casting crystallizer under the siphoning action, a crystallized conductive copper rod in the upward continuous casting crystallizer is drawn out of the top of the upward continuous casting crystallizer by a drawing device, and finally, the prepared conductive copper rod is packaged into coils. Compared with a polycrystalline conductive copper rod, the produced single-crystal conductive copper rod has the advantages that elongation percentage can be increased by 60%-80%, and specific resistivity can be reduced by 15%-20%.
