Ferrous metals â?? iron and its alloys (steels, ferroalloys, cast irons), account for more than 90% of the total volume used in the economy of metals, of which the main part is made up of various steels, steel tubes, steel coils, rebar, rubber.
Ferrous metals are used to make railway rails, pipes for transporting oil and gas, metal scaffolding, anchors for swimming facilities, nails, needles, springs, and much more.
Sponge iron filter material adopt high grade ore, using the REDOX reaction principle, through a filter in addition to the lake way out, pipe, boiler and circulating water dissolved oxygen corrosion after water treatment water dissolved oxygen content can be below 0.05 mg/L.In rotary kiln, shaft furnace or other reactor, coal, coke, gas or hydrogen gas, iron ore and pellets of iron concentrate in below material melt temperature under the condition of low temperature reduction, become the product of cellular.The reduction of iron in small iron core, such as sea jin, therefore calls.Sponge iron

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe3O4, 72.4% Fe), hematite (Fe2O3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)n(H2O), 55% Fe) or siderite (FeCO3, 48.2% Fe).
Ores containing very high quantities of hematite or magnetite (greater than about 60% iron) are known as natural ore or direct shipping ore, meaning they can be fed directly into iron-making blast furnaces. Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel 98% of the mined iron ore is used to make steel.

Cast Iron and Ductile Iron tube and fittings PL739
Cast Iron and Ductile Iron tube and fittings can be offered by our comapny to meet different engineering needs.
The difference between ductile iron and gray iron
1. Different chemical composition
Nodular cast iron contains nodular graphite, which can improve its toughness and strength, while reducing brittleness. Gray cast iron contains a lot of carbon, so that its hardness and wear resistance is high, but the toughness is poor.
2. Different organizational structures
The structure of nodular cast iron contains nodular and ferrite, and the distribution of nodular is uniform. While the structure of gray cast iron is mainly ferrite and pearlite, and the distribution of pearlite is uneven.
3. Different performance
Ductile iron has high strength and toughness, and has good corrosion resistance. It is uitable for the manufacture of high load and high pressure parts. The hardness and wear resistance of gray cast iron are high. It is suitable for the manufacture of friction and wear parts.
Application field
Cast iron : because of its low strength and good vibration resistance. It is often used in the production of parts under compressive stress, such as box, base, etc.
Ductile iron : because of its high strength and good toughness. It is often used in the manufacture of parts requiring high strength and toughness, such as crankshaft, connecting rod and so on.
Iron ore is the main raw material that is used in the manufacturing of steel. 98% of the mined iron ore goes in the steel production. India has rich deposits of Iron Ore and is among the top 10 exporter of iron ore in the world.
