Two types of pig iron can be used for ductile iron casting: high purity pig iron (HPPI) produced in electric arc furnaces as a byproduct of TiO2 production from ilmenite ores, and conventional pig iron produced in blast furnaces from iron ore. In Europe, blast furnace pig iron is often used (Yilmaz et al., 2015).

احصل على السعرBlast Furnaces produce iron with a carbon content of 3–4% and minor amounts of other impurities including sulfur, silicon, and other metals. This is known as Pig Iron. Wrought iron is made by heating cast iron in a furnace coated with haematite Fe 2 O 3. Carbon is reacted with Haematite to produce pure iron, and carbon monoxide gas is

It can also be used in casting (including steelmaking and iron), fertilizer, gasification and civil industries. Coke briquette comes from the coke briquetting process, the way which uses a coke briquetting machine to briquette

احصل على السعرIn Europe, blast furnace pig iron is often used ( Yilmaz et al., 2015 ). In contrast, the ductile iron industry typically uses HPPI because it is expected to promote graphite nodule formation due to its low manganese, phosphorus, and sulfur content ( Zhu, 2021 ).
احصل على السعرHow pig iron is produced in blast furnace? Blast furnaces produce pig iron from iron ore by the reducing action of carbon (supplied as coke) at a high temperature in the presence of a fluxing agent such as limestone.. What is cast iron? cast iron, an alloy of iron that contains 2 to 4 percent carbon, along with varying amounts of silicon and manganese
