Summary: | The invention provides a low-magnesium low-rare-earth vermicular wire and a production process thereof, and belongs to the technical field of vermicular cored wires, the low-magnesium low-rare-earth vermicular wire comprises a steel belt, a core material is wrapped in the steel belt, and the core material comprises the following raw materials in parts: 40-50 parts of silicon, 4.5-5.5 parts of magnesium, 4-5 parts of rare earth, 1-3 parts of calcium and a proper amount of trace elements. And the wire diameter of the vermicularizing wire is phi 13 to 13.5 mm. According to the structure characteristics of the vermicular graphite cast iron, the influence of magnesium, rare earth, calcium, silicon, other trace elements and other elements on the solidification process and solidification structure of the vermicular graphite cast iron is combined, the matrix structure and the graphite form are changed, and through scientific matching of element types and numbers, the vermicular graphite cast iron is obtained.
