Description

Technical Field

[0001] The utility model relates to the technical field of casting processing, in particular to a sulfur-oxygen inoculant adding device for casting. Background Art

[0002] The spheroidization rate of ductile iron refers to the proportion of spheroidized iron in the spheroidizing treatment, and is an important indicator for evaluating the quality of spheroidized iron. Spheroidized iron is cast iron that has undergone spheroidizing treatment and has good plasticity and toughness. It is suitable for manufacturing products such as mechanical parts that require high strength and wear resistance. The spheroidization rate of ductile iron plays an important role and has a decisive influence on the performance and quality of castings. Oxygen-sulfur inoculant is a commonly used inoculant in ductile iron production. It is a mixture of various compounds such as iron oxide, magnesium oxide, visual chloride, zirconium oxide, and copper oxide. In the production of ball seat cast iron, the addition of oxygen-sulfur inoculant can regulate the chemical composition of molten iron, promote spheroidization, and reduce defects.
