  • How Is Cast Iron Made? Sciencing

    Cast iron begins its life as pig iron, which is remelted and often combined with large amounts of scrap iron and sometimes with steel. Contaminants are removed from the melted pig iron, and the iron, once melted, is then cast. Casting is the process of pouring the iron into a mold thus giving it a shape. Molds and pouring methods divide this process up. Molds can be made as expendable molds

  • Iron processing Britannica

    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

  • Steps in the Modern Steelmaking Process

    Ironmaking, the first step in making steel, involves the raw inputs of iron ore, coke, and lime being melted in a blast furnace. The resulting molten iron—also referred to as hot metal—still contains 4-4.5% carbon and other impurities that make it brittle.

  • Cast Iron Production Hargreaves Foundry : A Cast Iron

    Cast Iron Production The Production of Cast Iron: Hargreaves Foundry employs traditional sand casting techniques enhanced by modern materials and technology. There are four stages in production; Design, Pattern Making, Mould Making and Casting. Design: converting ideas into solid metal requires a planned approach that takes into account the function of the object as well as its appearance. For

  • Ironmaking 101 From Ore to Iron with Blast Furnaces

    Many technologies are leveraged in a blast furnace to enhance iron making yield, throughput and hot metal quality such as modern tuyere and oxygen injection designs, refractories with improved iron and slag resistance, improved burden feeders, gas and energy recovery and advanced process control systems. Emerging technologies are being implemented to reduce or eliminate byproduct slag waste

  • Creating Iron HowStuffWorks

    Cast iron, as the name implies, is typically cast into molds to form a wide variety of parts and products. ­The third opt­ion for pig iron is to push the refining process even further and create steel, which we'll examine on the next page. What If? What if you only ate one type of stone for the rest of your life? What if Humans Could Breathe Underwater? What if You Were on an Elevator and the

  • Processing Techniques and Productions of Ductile Iron: A

    Processing Techniques and Productions of Ductile Iron: A Review J.O. Olawale, S.A. Ibitoye, K.M. Oluwasegun Abstract—Ductile cast irons are materials having strength, impact toughness and ductility comparable to those of many grades of steel while exceeding by far those of standard gray irons. In addition, they have the same advantages of design flexibility and low cost casting procedures of

Shaping & Coating The liquid steel can then be cast or formed into a variety of solid shapes via the 'continuous casting' process. The cast steel can then be forged or rolled in successive steps to produce anyone

  • How Is Ductile Iron Pipe Made? McWane Ductile

    Visitors who tour a McWane Ductile facility are often surprised by how much work goes into making Ductile iron pipe.The pipe starts out as scrap metal from old cars and demolished buildings that is melted down and given a new lease on life. Up to 95% of our product is made from recycled material.

  • The Metal Casting Process Explained General Kinematics

    Later, around 2000 BCE, iron was discovered. But it was not until around 700 BCE that the first production of cast iron was developed in China. Interestingly enough, the sand molding process of casting metals was also invented in China in 645 BCE.

  • Casting Patterns and Patternmaking Metal Casting Blog

    Casting is the process of pouring liquid metal into a mold, where it cools and solidifies. The casting process can produce everything from art pieces to engine parts. The shape is determined by the mold cavity, but something needs to shape the mold—that’s where the pattern comes in. Patterns are a model for the object to be cast. A pattern

  • How is Iron Made Into Steel? Sciencing

    Iron was the dominant metal for use in building and machinery until the modern era. Iron is still the main component of steel but when impurities are removed in the steel-making process, a stronger, lighter material results (steel). Steel is used in almost all modern buildings, automobiles, aircraft and appliances.
