Oct 02, 2014· Pig Iron. Pig iron is the basic material from which, wrought iron and steels are produced. It is obtained by smelting (chemical reduction) of iron ore in the blast furnace. In addition to iron, Pig iron contains varying quantities of other elements such as carbon, …
The pig iron can be further refined to produce steel or wrought iron. Both these methods reduce the carbon content of the pig iron, which in turn reduces the brittleness property of the metals. Wrought Iron Process. Wrought iron is produced by pummeling the pig iron using mechanically driven hammers in a wrought iron works.

Guide for manufacturing and making Pig Iron. Following three distinct operations are involved in the manufacturing process of pig-iron: (1) Dressing (2) Calcination and roasting (3) Smelting. (1) Dressing: The iron ores as obtained from mines are crushed into pieces of size of 25 mm diameter. This is achieved in the rock crushers of ordinary type.
Pig iron is produced in the blast furnace sector. The raw materials used include ore, sinter, coke, lime and various aggregates. To ensure that the production process maintains a high and stable level of quality, these materials have to be metered precisely and supplied to the blast furnace in batches. Teamwork. Process-controlled blast furnace ...
coke (also used as energy input to the process) or alternative reducing agents, limestone and dolomite. Steel production requires iron, steel scrap and lime (burnt limestone). The iron ore is smelted to produce an impure metal called "hot metal" when in liquid phase or "pig iron" when in solid phase.
In HIsarna ironmaking process, iron ore is processed almost directly into liquid iron or hot metal. The process is based around a type of blast furnace called a cyclone converter furnace, which makes it possible to skip the process of manufacturing pig iron pellets that is necessary for the basic oxygen steelmaking process.
Pig iron is an intermediate product of the iron industry, also known as crude iron, which is obtained by smelting iron ore in a blast furnace.Pig iron has a very high carbon content, typically 3.8–4.7%, along with silica and other constituents of dross, which makes it very brittle and not useful directly as a material except for limited applications.. The traditional shape of the molds used ...
The production of iron from its ore involves an oxidation-reduction reaction carried out in a blast furnace. Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue. The iron found in iron ores are found in the form of iron oxides.
For general information about merchant pig iron, please visit the pig iron page. Modern blast furnaces produce more than 10,000 tonnes per day. Blast Furnace Process. The blast furnace is a counter-current gas/solids reactor in which the descending column of burden materials [coke, iron ore and fluxes/additives] reacts with the ascending hot gases.
International Iron Metallics Association. The IIMA is dedicated to those involved in the ore-based metallics value chain - raw material supply, production and transformation, trading and distribution, transportation and logistics, technology and equipment.
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.
Production of Pig Iron by Using the Romelt Process . In the iron and steel industry in the world there are currently two types of factories that produce ferrous metals. There are so-called integrated plants, which start from the extraction of iron ore from the mine to the final rolled products.
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 combinations are known as iron …
After mining, various kinds of iron ores are brought to the blast furnace which is the starting process for refining iron ores or mined ores and for the production of pig iron. Blast furnace was invented in 14th century. A typical blast furnace along with its various parts is shown in Fig. 1.
A production of pig iron has been conducted from crushing plant waste. The process of preparing pig iron was using hot blast cupola (HBC) furnace which was injected with charcoal powder to improve temperature process and reduction zone in the furnace.
Jun 21, 2016· Primary Steel making Process. It is the process of making steel from carbon-rich molten pig iron. The process was introduced and developed in 1948 by Robert Durrer. However, VOEST and OAMG commercialized this method in 1952–53. The name LD converter came after the name of the two Austrian towns Linz and Donawitz.
Pig iron was originated in the early days by reduction or iron ores in blast furnace and when the total output of the blast furnace was sand cast into pigs which is a mass of iron roughly resembling a reclining pig. It is roughly of 20″ × 9″ × 4″ in size. It is produced in a blast furnace and is the first product in the process of converting iron ore into useful ferrous metal.
Jun 28, 2015· Pig iron and its manufacturing Pig iron is the crude form of iron and is used as a raw material for the production of various other ferrous metals, such as cast iron, wrought iron and steel. The pig iron is obtained by smelting iron ores in a blast furnace.
May 16, 2019· The Modern Steel Production 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.

Nodular Pig Iron, also known as S.G. Pig Iron is used as a high purity furnace charge addition, primarily for the production of Ductile Irons. Contains low levels of deleterious trace elements enabling consistent production of ferritic grades. A low Sulphur content helps to maximise the recovery of Magnesium during the nodularisation process.
Sep 17, 2019· The name “pig iron” comes from the resemblance of the long channel to a mother pig, and the smaller channels to suckling piglets. In most modern pig iron production, however, this process is no longer used, as methods have been developed that allow the pig iron to be transported in a liquid state, rather than as a hard material.
Pig-Iron Production from Microsoft Encarta. The basic materials used for the manufacture of pig iron are iron ore, coke, and limestone. The coke is burned as a fuel to heat the furnace; as it burns, the coke gives off carbon monoxide, which combines with the iron oxides in the ore, reducing them to metallic iron.
