The process of sponge iron manufacturing involves removal of oxygen from iron ore. When that happens, the departing oxygen causes micro pores in the ore body, turning it porous. When the eventual product is observed under a microscope, it resembles a honeycomb structure, which looks spongy in texture. Hence the name sponge iron. More Details. Ppt Presentation On Sponge Iron .
The sponge iron process. The longest established of these processes is the sponge iron process, the leading example of a family of processes involving solid state reduction of an oxide. In the process, selected magnetite (Fe3O4) ore is mixed with coke and lime and placed in a silicon carbide retort. The filled retort is then passed through a long kiln, where the reduction process leaves an ...
Ductile cast iron Ductile cast iron is the most versatile of cast irons. Also known as nodular CI. DCI is alloyed with magnesium(Mg)which precipitates out carbon in the form of small spheres. This improves some of the mechanical properties gray CI. This type of cast iron is produced by a process called "chilling" which prevents graphite carbon from precipitating out. In the cast iron, most ...
ο Ease of manufacture ο Overall cost of material and manufacture The materials generally used for making gears are : Δ Ferrous metals – for high loads • Grey cast iron – preferred for reasonable strength and wear resistance, ease of casting and machining and low cost • Forged or rolled high carbon steels and alloy steels (NiCr, Mo

Cast iron: Iron that contains about as much carbon as it can hold which is about 4%. Wrought iron: Iron that contains glassy inclusions. Steel: Iron with a bit of carbon in it— generally less than 1%. 4 Introduction to Iron and Steel A few definitions and general descriptions are in order Pig iron: Raw iron.
Gating and Risering Basics introduces the learner to the various components of the filling and feeding systems, as well as their role and design in transporting the molten metal into the casting cavity. This knowledge is foundational for designing the gating and risering systems for efficiently filling of the mold cavity to produce quality castings.

Steelmaking Process — Basic Oxygen Furnaces In the basic oxygen process (BOP), molten iron from a blast furnace and iron scrap are refined in a furnace by lancing (or injecting) highpurity oxygen. The input material is typically 70 percent molten metal and 30 percent scrap metal. The oxygen reacts with carbon and other impurities to remove them from the metal. The reactions are ...

The process starts in the center of the wheel with the three main ingredients of iron in the form of iron ore, coke and lime, which are fed into a blast furnace to produce molten iron. The molten iron is mixed with recycled steel scrap and further processed in a basic oxygen furnace to make steel. The electric arc furnace melts recycled steel scrap. The molten steel is formulated to precise ...

OMIROU 2 Sheet Metal Cutting Forming ProcessesGeneralThe raw material for sheet metal manufacturing processes is the output of the rolling process. Typically, sheets of metal are sold as flat, rectangular sheets of standard size. Therefore the first step in any sheet metal process is .
The figure shows a flowchart of the integrated manufacturing process for iron and steel using the blast furnace and basic oxygen furnace (denoted BF and BOF hereinafter, respectively), which is presently the most commonly used method (51% of world steel production). After the BFBOF process, molten steel is controlled to a target composition and temperature and is then cast by continuous ...
A sponge manufacturer typically checks the product for quality at many steps along the manufacturing process. The raw ingredients are analyzed when they come into the plant to make sure they conform to standards. In a modern facility, most of the machinery is monitored by computers, that maintain the proper proportions in the mix, for example, and control the temperature of the mold during the ...
