The invention provides a production system of cast iron containing copper. The production system comprises a heating and settling furnace, a reducing furnace, a smelting furnace and a casting device,wherein the heating and settling furnace comprises a heating reduction area and a settlement area, and the heating reduction area communicates with the bottom of the settlement area; a material outletof the settlement area comprises a first liquid outlet and a first slag outlet; a material inlet of the reducing furnace communicates with the first slag outlet of the settlement area, and a materialoutlet of the reducing furnace comprises a second liquid outlet and a second slag outlet; a material inlet of the smelting furnace communicates with the second liquid outlet of the reducing furnace;and a material inlet of the casting device communicates with a material outlet of the smelting furnace. The production system for producing the cast iron containing copper has high recovery rate and low production cost, can realize the extraction of valuable elements, and makes full use of iron and copper in copper slag. The production system can obtain corrosion-resistant cast iron containing copper by adding manganese, silicon, copper, chromium, nickel and molybdenum alloys, so the value of the product can be greatly enhanced, and the economic benefit can be improved.
