Abstract

The invention discloses a smelting device for a single-crystal conductive copper rod. The smelting device comprises an upward continuous casting melting furnace and a closed mixing melting furnace, wherein a melting furnace closing top cap is arranged at the top of the closed mixing melting furnace; a reducing gas discharge pipe is arranged on the melting furnace closing top cap; a reducing gas blowing-in pipe, a molten copper liquid guide pipe and a guide pipe sealing guide sleeve are arranged at the bottom of the closed mixing melting furnace; the lower end of the molten copper liquid guide pipe is located below the liquid level of the molten copper liquid in the upward continuous casting melting furnace; the molten copper liquid guide pipe descends at a constant speed, so that the molten copper liquid in the closed mixing melting furnace flows into the upward continuous casting melting furnace at the constant speed, and mass of the molten copper liquid flowing through the molten copper liquid guide pipe in unit time is equal to that of the total mass of the molten copper liquid flowing through an upward crystallizer in unit time. With the adoption of the smelting device, uniform addition and blending of additive composition, prepared with a specific formula, in the single-crystal conductive copper material can be realized.

Description

technical field [0001] The invention relates to the technical field of copper processing equipment, in particular to a single crystal conductive copper rod smelting device. Background technique [0002] Single crystal conductive copper is a new type of conductor material compared to polycrystalline conductive copper. Since the transverse grain boundary is canceled in the metal microstructure, the conductivity of conductive copper and the protection of signal transmission can be significantly improved. Authenticity; In terms of specific extensibility and conductivity, compared with polycrystalline conductive copper rods, single crystal conductive copper can increase the elongation by 60% to 80%, and the resistivity can be reduced by 15% to 20%, which can be widely used In audio-visual equipment, high-definition television and other electronic information-related fields. The production of single crystal conductive copper mainly adopts the method of combining directional solid...
