Afbeeldingen van iron manufacturing process
Iron ore is converted into various types of iron through several processes. The most common process is the use of a blast furnace to produce pig iron which is about 92-94% iron and 3-5% carbon with smaller amounts of other elements.

5-7-2020 · Iron processing, use of a smelting process to turn the ore into a form from which products can be fashioned.Included in this article also is a discussion of the mining of iron and of its preparation for smelting. Iron (Fe) is a relatively dense metal with a silvery white appearance and distinctive magnetic properties. It constitutes 5 percent by weight of the Earth’s crust, and it is the ...
Iron processing - Iron making | Britannica
7-7-2020 · Iron processing - Iron processing - Iron making: The primary objective of iron making is to release iron from stone combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way.

Manufacturing Process of Cast Iron Castings
Manufacturing Process of Cast Iron Castings . The making of cast iron begins with a combination of raw materials. Iron is rarely found in its pure form. Only meteorites contain pure iron. The iron in use for centuries is found in the combination of iron and other elements. These ...
How Is Cast Iron Made? | Sciencing
Cast iron that has not cooled evenly produces a low-quality cast. Other problems faced during the cast iron process include contamination of the iron, gas porosity (the forming of bubbles in the iron), and problems with the fluidity of the metal. The casting process is an art that must be examined and experienced to be fully understood.

Secondary steelmaking is a refining process in which alloying metals are added and impurities are removed. Check out this infographic for an overview of the products that make each stage of the iron and steel manufacturing process possible, from incoming raw materials to the final coating line.
The Making of Iron & Steel - SEAISI
Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as "gangue". The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke as both a fuel and reducing agent.
Cast iron - Wikipedia
Cast iron is a group of iron-carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its colour when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the ...
Wrought iron - Wikipedia
Wrought iron is an iron alloy with a very low carbon (less than 0.08%) content in contrast to cast iron (2.1% to 4%). It is a semi-fused mass of iron with fibrous slag inclusions (up to 2% by weight), which gives it a "grain" resembling stone that is visible when it is etched or bent to the point of failure. Wrought iron is tough, malleable, ductile, corrosion-resistant and easily welded.
Manufacturing — Maritime Iron
1. Iron feed flexibility. The technology utilizes iron feeds and fines that normally cannot be used by traditional steel-making technologies. This holds several advantages. By being able to use off-specification iron feeds, Maritime Iron can lower its input costs. The process does not require premium cost iron pellets or lump.

Steps in the Modern Steelmaking Process
Methods for manufacturing steel have evolved significantly since industrial production began in the late 19th century. Modern methods, however, are still based on the same premise as the original Bessemer Process, which uses oxygen to lower the carbon content in iron.
