Steelmaking pig iron (white cast iron)
CustomizableTransportation modes：Including sea transportation, railway transportation, and road transportation.Minimum order quantity：Comprehensive evaluation based on actual orders.Qualification certification： Complete qualifications to ensure reliable quality.Sales countries：We have provided products to users regions including Asia, Southeast Asia, Europe, North America, and Africa, serving countries such as the United States, Japan, South Korea, France, Germany, Thailand, Vietnam, the United Arab Emirates, and Saudi Arabia. Looking ahead, we eagerly anticipate cooperating with more global buyers.Steelmaking pig iron, also known as white cast iron, is the main product of continuous cast steel ironmaking in blast furnaces. Its characteristic is that it has a low silicon content (generally not greater than 1.75%) and a relatively high sulfur content (but less than 0.07%). Due to the combined state of iron and carbon, the fracture surface of steelmaking pig iron appears white, with a brittle and hard texture.In addition to iron, steelmaking pig iron also contains elements such as carbon, silicon, manganese, phosphorus, and sulfur, which have a significant impact on the properties of pig ironCarbon (C): Exists in the form of compound carbon (iron carbide), hard and brittle, with low plasticity. Moderate content can improve the strength and hardness of pig iron, but excessive content makes it difficult to cut and process pig iron.Silicon (Si): It can promote the separation of carbon in pig iron into graphite like form, remove oxygen, reduce casting gas holes, improve the fluidity of melted pig iron, and reduce casting shrinkage. But excessive silicon content can also make pig iron harder and brittle.Manganese (Mn): It can dissolve in ferrite and cementite, improving the casting and cutting properties of pig iron. In the blast furnace, manganese can also form manganese sulfide with harmful impurity sulfur and enter the slag.Phosphorus (P): It is a harmful element, but it can increase the fluidity of molten iron (by lowering the melting point of pig iron). However, the presence of phosphorus increases the hardness and brittleness of iron, and excellent pig iron should have a low phosphorus content.Sulfur (S): It is a harmful element that promotes the combination of iron and carbon, making iron hard and brittle, and reacts with iron to form low melting point sulfide iron, causing thermal brittleness of pig iron and reducing the fluidity of molten iron.Steelmaking pig iron accounts for over 90% of blast furnace pig iron production and is the main raw material for oxygen top blown converter steelmaking in modern steel production. It is also used in electric furnace steelmaking (accounting for over 30% of metal materials). The quality requirements for steelmaking pig iron include:When the demand side has special requirements for silicon content, it shall be stipulated by the agreement between the supply and demand parties.Units that use high phosphate ore smelting must obtain approval from the national competent department, and the phosphorus content of pig iron is allowed to not exceed 0.85%.The numbers after the significant digits of sulfur and phosphorus content in the chemical composition table are not allowed to be rounded off.When smelting with copper containing ore, the copper content of pig iron is allowed to be no more than 0.30%.The production of steelmaking pig iron is mainly carried out in blast furnaces, with raw materials including iron ore, coke, flux, etc. The reducing gas in the blast furnace is generated by the combustion of fuel in front of the tuyere. Iron ore is refined into pig iron through reduction reaction, and the molten iron is released from the tapping port. At the same time, the ash content in the gangue, coke, and injection material in the iron ore combines with the flux such as limestone added to the furnace to form slag, which is discharged from the tapping port and slag outlet respectively.In summary, as the main raw material for steelmaking, pig iron has specific chemical composition and physical performance requirements. In the production process, it is necessary to strictly control the quality of raw materials and production process parameters to ensure that the quality of steelmaking pig iron meets the requirements of steelmaking.

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 range of pig iron used in 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.4. Selection and Quality Control of Ductile IronDuctile iron is a high-quality cast iron material with high strength and toughness, widely used in fields such as mechanical manufacturing, automotive manufacturing, and bridge construction. Ductile iron, as the main raw material for producing ductile iron, plays an important role in the casting process. By strictly controlling key factors such as raw material quality, chemical composition, and production processes, high-quality ductile iron products can be produced.Chemical composition control: The chemical composition of ductile iron has a significant impact on its properties. Therefore, it is necessary to strictly control the chemical composition of pig iron during the production process to ensure the quality of castings.Raw material quality: Choosing high-quality raw materials is crucial for producing high-quality ductile iron. This includes selecting high-quality raw materials such as iron ore and coke, and ensuring that their quality meets relevant standards.Production process control: The production process also has a significant impact on the quality of ductile iron. Therefore, it is necessary to strictly control parameters such as temperature and time during the casting process to ensure the performance and quality of the castings.5. Application scenarios and industriesDuctile iron is a high-strength cast iron material developed in the 1950s, with comprehensive properties similar to steel. Based on its excellent properties, it has been successfully used to cast parts with complex stress, high requirements for strength, toughness, and wear resistance. Ductile iron has rapidly developed into a widely used cast iron material, second only to gray cast iron. The so-called "replacing steel with iron" mainly refers to ductile iron.The mechanical properties of ductile iron are superior to gray cast iron and similar to steel.

Definition of Pure Iron: Iron-based materials with an iron content of not less than 99.50% and a carbon content of not more than 0.0218%.According to the purity level (N representing the purity level of pure iron), pure iron can be classified as follows:Industrial Pure Iron: purity 99.50-99.80%, 2NPure Iron: purity 99.90~99.94%, 3NHigh-Purity Iron: purity 99.950~99.998%, 4NUltra-Pure Iron: purity 99.999~99.9999%, 5N-6N1、We have developed a process technology for large-scale pyrometallurgical production of 4N grade high-purity iron through technological innovation, reducing the production cost of high-purity iron and providing high-quality raw materials for the high-end equipment manufacturing industry.2、2N-3N grade Industrial Pure IronIts purity ranges from 99.50% to 99.94%, and it can be industrially produced through pyrometallurgical processes. Pure iron exhibits soft texture, high toughness, and excellent electromagnetic properties. Primarily used in amorphous, electronic, rare earth permanent magnet, electromagnetic pure iron, new energy, high temperature, high strength, and other fields, it serves as the basic iron-based metal material in these sectors.3、4N grade High-Purity IronHigh-purity iron serves as a crucial basic material for the preparation of high-performance functional materials, including magnetic materials and amorphous materials. It is a superior electromagnetic shielding material and a key raw material for the production of high-quality alloys, such as high-end special steel, high-temperature alloys, corrosion-resistant alloys, nuclear industry materials, and military steel. It is extensively utilized in high-end sectors such as energy, rail transportation, machinery, military equipment, aircraft, spacecraft, gas turbines, marine engineering, petrochemicals, and semiconductor chips.Characteristics of 4N grade high-purity iron products:As the purity of pure iron increases, its yield strength and tensile strength decrease, while the sensitivity of strength to strain rate increases. Grain coarsening significantly reduces the yield strength of 4N grade high-purity iron at low strain rates, with the yield strength of 4N4 coarse pure iron being only 58MPa.① Coarse grain size and low yield strengthThe mechanical properties of 2N8, 3N5 pure iron and kilogram-grade 4N4 pure iron materials produced through industrialization were tested. The microstructures after annealing at different purities are shown in the figure, with average particle sizes being 2N8 (58um) = 3N5 (58um) < 4N4 pure iron (328um).② Excellent soft magnetic performancePure iron has been long utilized as a material for high-soft magnetic equipment, such as magnetic cores, owing to its excellent ductility, low strength and hardness, as well as high magnetic permeability. Impurities play a significant role in influencing the soft magnetic properties of pure iron.③ Corrosion resistance of high-purity ironAfter reaching high purity, pure iron is not easy to rust in humid air and is insoluble in hydrochloric acid, sulfuric acid, etc.CustomizableTransportation modes：Including sea transportation, railway transportation, and road transportation.Minimum order quantity：Comprehensive evaluation based on actual orders.Qualification certification： Complete qualifications to ensure reliable quality.Sales countries：We have provided products to users regions including Asia, Southeast Asia, Europe, North America, and Africa, serving countries such as the United States, Japan, South Korea, France, Germany, Thailand, Vietnam, the United Arab Emirates, and Saudi Arabia.
