The invention provides a clean smelting device and a technology of low-grade scrap copper. A melting furnace and reduction furnace are rotary horizontal cylindrical furnace bodies; flue port of the melting furnace is connected with a smoke inlet of the oxidation-reduction furnace through a flue; a smoke outlet of the oxidation-reduction furnace is connected with a secondary combustion chamber; a copper feed port of the melting furnace is connected with a feed port of the oxidation-reduction furnace through a guide pipe; a plurality of natural gas burners are arranged on one side of the smoke inlet of the oxidation-reduction furnace; two flue ports are formed at the top of the oxidation-reduction furnace; one flue port is a smoke inlet of the melting furnace and is formed at one end of a furnace body; the other flue port is a smoke outlet of the melting furnace and is formed at the other end of the furnace body; the melting furnace and the oxidation-reduction furnace are in parallel axially and not in the same
