Its performance is superior to other cast iron materials, such as ductile iron and white cast iron, and therefore it has been widely used in the industrial field. Ductile iron products play an important role in fields such as petroleum, chemical, hydropower, and mechanical manufacturing.The production process of ductile iron is to put raw materials such as iron ore, iron ore sand, coke, and limestone into a high-temperature furnace, add inoculants, and make the molten iron form spherical shapes during the flow process. This process can form a spherical structure in the molten iron during the cooling process, thereby improving the strength and toughness of the material. The mechanical and physical properties of ductile iron are superior to other cast iron materials.Ductile iron products have high strength and toughness, and can withstand significant pressure and impact loads. Therefore, in the field of petrochemicals, ductile iron is widely used in the manufacture of key equipment such as pressure vessels and reaction vessels. In addition, ductile iron is also used to manufacture equipment such as pipelines, valves, pumps, as well as components of mechanical equipment such as water turbines and compressors.In the field of hydropower, ductile iron is used to manufacture key components of equipment such as water turbines and generator sets, such as runners and blades. Due to its high strength and toughness, ductile iron can withstand the impact load of water flow, thus improving the efficiency and reliability of hydropower equipment.In the field of mechanical manufacturing, ductile iron is used to manufacture various mechanical parts such as gears, bearings, pulleys, etc. Due to its good wear resistance and corrosion resistance, ductile iron can improve the service life and reliability of mechanical parts.Compared with other materials, ductile iron has a higher cost-effectiveness. It has good mechanical and physical properties, as well as a simple production process and low cost. However, ductile iron also has some limitations, such as high density, which is not conducive to lightweight applications.

Definition and OverviewDuctile iron is a type of pig iron in which graphite is distributed in a spherical shape through specific processes such as spheroidization and inoculation. It is the main raw material for producing ductile iron, and its quality directly affects the performance of castings. Ductile iron contains high levels of carbon and other alloying elements in pig iron, which can react with spheroidizing agents and inoculants during the casting process to form spherical graphite, thereby improving the strength and toughness of castings. Usually, the amount of pig iron used accounts for 60% -70% of the total amount of raw materials.2. The role of ductile iron in the production of ductile ironProviding basic materials: Ductile iron, as the main raw material for producing ductile iron, provides the necessary iron foundation for the casting process.Formation of spherical graphite: In the production process of ductile iron, by adding spheroidizing agents and inoculants, and controlling appropriate casting conditions, graphite can be distributed in a spherical shape in pig iron. This spherical graphite structure greatly improves the mechanical properties of cast iron.Improving casting performance: Due to the presence of spherical graphite, the strength and toughness of ductile iron have been significantly improved. This makes ductile iron have better application performance in situations with complex stress and high strength requirements.3. Chemical composition and customization of ductile iron (product specifications)According to different performance requirements, ductile iron has multiple grades, such as Q10, Q11, Q12, etc. The chemical composition of ductile iron usually includes elements such as carbon (C), silicon (Si), manganese (Mn), sulfur (S), phosphorus (P), etc. Due to different standards, uses, batches of production, and customized needs of users, the parameters of chemical composition are not fixed at a certain value, but generally have a range. The following shows the chemical composition of pig iron used in some batches of ductile iron.We will have in-depth negotiations with you and provide you with suitable pig iron according to your actual needs, helping you reduce procurement costs and ensure the quality of ductile iron.Customization can be provided.

And ductile iron is mainly produced by adding elements such as magnesium and manganese to cast iron, thereby achieving the formation of spherical graphite.2、 Mechanical performanceCast pig iron has strong hardness and brittleness, with lower strength than ductile iron, but its wear resistance and cutting performance are better. And ductile iron has high strength, high toughness, good plasticity and reliability, and its wear resistance is significantly improved compared to cast pig iron, making it suitable for high-strength fields such as large machine tools and mechanical parts.3、 Purpose:Due to their different mechanical properties, the two types of pig iron materials also have different uses. Cast pig iron is suitable for producing lubricants, pipelines, shafts, light mechanical parts, etc; And ductile iron is suitable for high-strength fields, such as axle housings, petroleum machinery parts, high-pressure pipe fittings, etc.4、 CraftsmanshipThere are also differences in the production processes of cast pig iron and ductile iron. Casting pig iron requires processes such as starch modeling and sand casting; However, ductile iron requires spheroidization treatment, which involves adding molten metal to a specific material before casting, so that the graphite in the molten iron appears spherical, thereby improving its mechanical properties.Overall, there are significant differences between cast pig iron and ductile iron in terms of composition, mechanical properties, applications, and production processes. In casting production, suitable materials need to be selected according to specific usage situations.
