How Pig Iron is Converted into Iron and Steel in Blast

Blast Furnace. 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. It is large steel shell about 9 mt

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. The process is continuous with raw materials

Blast furnace metallurgy Britannica

Blast furnaces produce pig iron from iron ore by the reducing action of carbon (supplied as coke) at a high temperature in the presence of a fluxing agent such as limestone.Ironmaking blast furnaces consist of several zones: a crucible-shaped hearth at the bottom of the furnace; an intermediate zone called a bosh between the hearth and the stack; a vertical shaft (the stack) that extends from

Pig Iron Manufacturing Process

This is because the electric furnace can be operated with the proper metallurgical conditions for the production of pig steel rather than pig iron, and because in a possible design of shaft furnace similar to the blast furnace there is a greater chance for the production of a larger tonnage than is possible in the case of furnaces used in combustion direct steel processes.

Blast furnace process tec-science

Combustion process. The iron in the processed ores must be dissolved out by stone processes. This requires an element that binds oxygen more strongly than iron. This is exactly what carbon can do as a reducing agent.The carbon is fed to the blast furnace in the form of coke (pyrolyzed coal) from the coking plant.At sufficiently high temperatures, the carbon can participate directly in the

Extraction of Iron Metallurgy Blast Furnace and Reactions

The iron manufactured in Blast Furnaces contain about 3 4 % of Carbon and smaller quantities of many other impurities such as sulfur, Silicon, etc. This is called Pig Iron. It is a hard but brittle metal and the impurities severely hamper its strength. Carbon seems to play a significant role in influencing the brittleness and hardness balance in iron. To further reduce the carbon content

Pig iron Wikipedia

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

Pig-Iron Production Google Sites

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. This is the basic stone reaction in the blast furnace; it has the equation: Fe

Ironmaking 101 From Ore to Iron with Blast Furnaces

Ironmaking Blast Furnace. Iron is made by reacting iron ore (iron oxide and impurities), coke (a reductant) and limestone (CaCO 3) in a blast furnace. Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities. The iron ore is dressed or crushed into 0.5-1 in. chunks

In the blast furnace, liquid pig iron is produced from processed iron ores in a continual smelting process. The blast furnace generates heat of over 2000 degrees Celsius in order to melt iron from the iron ore. To reach this temperature, coke is used as fuel and the fire inside the furnace is fanned with hot air at 1400 degrees Celsius. Also, limestone is added for the purpose of bonding

HOW A BLAST FURNACE WORKS Introduction The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called "hot metal". The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom. The raw materials require 6 to 8 hours to descend to the
