✔️ Everything about Industrial Iron
Iron is the fourth most common element in the earth's crust (after oxygen, silicon, and aluminum) and the second most common metal (after aluminum), but because it reacts easily with oxygen, it is never extracted in its pure form. (although they are meteorites). it is sometimes discovered to contain samples of pure iron). Like aluminum, most stagnant iron in the Earth's interior is in the form of oxides (compounds of iron and oxygen). Iron oxides are found in seven main minerals (raw minerals and rocks extracted from the earth):
- Hematite (the most abundant)
Limonite (also called brown ore or swamp iron)
- Gothite
- Magnetite (black stone; magnetic type of iron oxide, also called lodestone)
- Pyrite
- Siderite
- Taconite (combination of hematite and magnetite).
Different ores contain different amounts of iron. Hematite and magnetite contain about 70% iron, limonite about 60%, pyrite and siderite 50% and taconite only 30%. Using a combination of deep (underground) and open-pit (surface) mining, the world produces approximately 1,000 million tons of iron ore per year, of which China is responsible for just over half.
✔️ Types of Iron
Pure iron is too soft and reactive to have any real use, so most of the iron we tend to use is for everyday use. , is actually in the form of iron alloys: iron is mixed with other elements (especially carbon) to make it stronger. More flexible forms of metal including steel. In general, steel is an alloy of iron that contains about 2 percent carbon, while other forms of iron contain about 2 to 4 percent carbon. In fact, there are thousands of different types of iron and steel, all containing slightly different amounts of other alloying elements.
✔️ Raw Iron
Original raw iron is called iron ingot because it is produced in the form of large mold blocks called ingots. Pig iron is made by heating iron ore (rich in iron oxide) in a blast furnace: a huge industrial furnace, in the shape of a cylinder, into which huge streams of hot air enter in regular "blasts". Blast furnaces are often very large: some are 30–60 m (100–200 ft) high, hold dozens of truckloads worth of raw materials, and often run continuously for years without being shut down or cooled. are working Inside the furnace, iron ore reacts chemically with coking coal (a carbon-rich form of coal) and limestone. Coke steals oxygen from iron oxide (in a chemical process called reduction). It leaves behind a relatively pure liquid iron, while the limestone helps remove other hard ore parts (including clay, sand, and small stones) that form a waste slurry called slag. Iron made in a blast furnace is an alloy that, depending on the ore used, contains about 90-95% iron, 3-4% carbon and traces of other elements such as silicon, manganese and phosphorus. Pig iron is much harder than 100% pure iron, but still too weak for most everyday uses.
✔️ cast iron
One of the most famous iron buildings in the world, the Capitol in Washington, DC, has a dome made from 4,041,146 kilograms (8,909,200 pounds) of cast iron. Cast iron is simply liquid iron that has been cast: poured into a mold and allowed to cool and harden to form a finished structural shape such as a pipe, a gear, or a large girder for an iron bridge.
Pig iron is actually a very basic form of cast iron, but it is only very crudely cast, as it is usually melted down to produce steel. Cast iron's high carbon content (roughly the same as pig iron or pig iron - about 2 to 4 percent) makes it very hard and brittle: the large carbon crystals embedded in the cast iron prevent the iron crystals from moving. Cast iron has two major drawbacks: First, because it is hard and brittle, it is virtually impossible to shape, even when heated. Second, it rings relatively easily. It's worth noting that there are actually several different types of cast iron, including white and gray cast irons (so named because of the color of the finished product caused by the way the carbon in it behaves).
✔️ Iron made or a crimson
Cast iron takes its final shape the moment the liquid iron alloy cools in the mold. Wrought iron is a very different material made by mixing liquid iron with some slag (residual waste). The result is an iron alloy with a much lower carbon content.
Wrought iron is softer and much less hard than cast iron, so you can heat it to shape relatively easily, and it's also much less prone to rust. However, relatively little wrought iron is now produced commercially, as most objects made from it are now made from steel, which is both cheaper and generally of more consistent quality. Wrought iron is what people used before they became proficient at producing steel in large quantities in the mid-19th century.
✔️ Industrial Iron
Industrial iron tools are also available in various forms such as beams, pipes, rebars, iron sheets and profiles, with the difference that their industrial form should be much stronger than the form of construction iron tools; Because in large industrial metal structures, multi-story buildings and heavy industrial machinery are used, and they must be able to withstand heavy loads caused by the huge volume of industrial structures. It should be noted that the use of industrial iron is not only in large structures, and the manufacture of mechanical equipment, car manufacturing, electronic equipment and household appliances are also other uses of industrial iron.
✔️ Types of Industrial Irons
- Steel sections: This type of industrial irons are the most widely used forms of iron and steel alloys that have many uses in the iron market, especially in the field of industrial irons.
- Steel sheets: Steel sheets are iron alloys that are made in different sizes and thicknesses and are used in industries such as the production of oil and gas pipes and many other industries.
Steel sheet is widely used in construction and various industries. The reason is the excellent mechanical and physical characteristics of these products. Steel sheet is also called sheet or steel plate. Many large and small industries such as automotive industry, household appliances, rail construction, computer and electronic devices, building construction, road construction and many other small and large industries are customers of steel sheets.
There are many different types of sheet and it is made by cold and hot rolling methods. Black sheet or hot sheet or hot roll plate, cold sheet, galvanized sheet, shadowline, colored, punch, acid washing, tin plated, ribbed sheet, fireproof, aluminum, steel, stainless steel and anti-wear are different types of this product that are used in different industries and They are used for various applications in construction.
- transmission rod
Transmission rod is one of the most widely used types of industrial rods and steel sections in the industry.
Various types of transmission and automatic steels are imported from Turkey, Taiwan, Italy and other countries of the world. They include:
1. Round shaft
2. Belt
3. Hexagon
4. Square
- Rails, beams, studs and hashes: steel rails are mainly used to mount wagons and locomotives on them.
Industrial beams and studs are also produced in different types with special industrial standards, in different dimensions and numbers, which are widely used in the industry.
Studs are U-shaped steel sections and are widely used in construction and industry.
Iron beam, like rebar, is one of the most widely used steel products that are used both in industry and in construction. The use of this steel section is so much that the smallest change in its price causes a change in the total costs of any project. Steel beams are used to restrain shear stresses and bending anchors in the building. The most widely used types of this product in Iran are produced in 14, 16 and 18 mm sizes. This construction profile is produced in four different types depending on its chemical and mechanical properties and depending on its application: IPE, INP, IPB and honeycomb beam or CPE.
- Industrial pipes: Industrial and mansiman pipes are a series of pipes that are produced in large thicknesses and high diameters. They are used in the transportation of oil and gas materials, etc. in different distances and difficult conditions and in different industries.
