Summary: | The invention discloses a preparation method of an electric stranded wire. The preparation method is characterized by comprising the following preparation steps of (1) raw material preparation, wherein raw materials comprise more than 50wt% of a regenerated copper electrolytic plate and the balance of a mineral copper electrolytic plate; and (2) smelting, wherein the electrolytic plates are put into a furnace to be molten, charcoal is added while melting is carried out, after melting, the temperature is kept at 1200-1250 DEG C, after the temperature is kept for 0.5-3 h, the electrolytic plates are transferred into a heat preservation furnace, charcoal is added into the heat preservation furnace for covering, the temperature of the heat preservation furnace is controlled at 1150-1200 DEG C, the temperature is kept for 1-2 h, and meanwhile mixed gas of inert gas and reducing gas is blown into the bottom of the heat preservation furnace. According to the method, more than 50wt% of regenerated copper is adopted a |
