The capacity of old blast furnaces was around 15000 kN of pigiron per day. The capacity of present day modern blast furnaces has gone upto 100000 or more kN of pig
1. The Bessemer Process. The Bessemer steel making process consists of blowing air through molten pig iron contained in a special furnace known as a converter which
Primary Steel making Process It is the process of making steel from carbonrich molten pig iron. As oxygen is passed through the molten pig iron to lower the
The Bessemer Process and Modern Steelmaking . The growth of railroads during the 19th century in both Europe and America put enormous pressure on the iron
Pig Slaughter Line Process Modern Slaughterhouse. Top sealed pig scalding tunnel:the pig body will be automatically conveying into the scalding tunnel from the pig bleeding line
Since the processes use only iron ore fines and non cokingcoal, FASTMET and FASMELT are expected to be the iron making processes of the 21st century, especially with the current roaring prices for lumpore and cokingcoal. 3. ITmk3R process The ITmk3 separates "nugget iron" and slag directly from the iron ore fines and
Pig iron Pig iron is the immediate product of smelting iron ore with coke and limestone in a blast furnace. Modern pig casting machines produce stick pigs, which break into smaller 410 kg pieces at discharge. The metal is then cast into molds or used in other processes. This is known as refined pig iron, finers metal or refined iron

blast furnace is a well known process. Overall process is written as: • Ironore oxide mineral + gangue + Reducer (C) + flux + hot blast oxygen enriched air = Pig iron (liquid) + Slag (liquid) + waste gas (CO,CO2,N2) • Iron ore contains Fe2O3, along with gangue materials such as SiO2, Al2O3. • Charge materials are: Iron ore + limestone
Basic raw iron is called pig iron because it's produced in the form of chunky molded blocks known as pigs. Pig iron is made by heating an iron ore (rich in iron oxide) in a blast furnace: an enormous industrial
In general, the pig iron is an intermediate product of the iron industry.Pig iron, known also as crude iron, is produced by the blast furnace process and contains up to 4–5% carbon, with small amounts of other impurities like sulfur, magnesium, phosphorus, and manganese.Pig iron is supplied in a variety of ingot sizes and weights, ranging from 3 kg
Primary Steel making Process It is the process of making steel from carbonrich molten pig iron. As oxygen is passed through the molten pig iron to lower the carbon content of the alloy, the process is also called basic oxygen steelmaking. The word basic is added with it for the chemical nature of the refractories magnesium oxide and
1. The Bessemer Process. The Bessemer steel making process consists of blowing air through molten pig iron contained in a special furnace known as a converter which shaped like a huge concrete mixer (Fig. 4.2).The converter is made of steel plates lined inside with a refractory material. The type of refractory lining used depends upon the character of the
Description. Pig iron is the intermediate product of smelting iron ore with a highcarbon fuel such as coke, usually with limestone as a flux. Charcoal and anthracite have also been used as fuel. Pig iron has a
Cementation Process: In this process wrought iron bars are introduced in a furnace in between powdered charcoal layers and are subjected to a very high temperature about 7000 Celsius for about a
With pig iron being the key ingredient in steel production and steel being the key to the modern building process, it is impossible to overstate the value of pig iron in industrial progress. The Meijer and den Hartog design as part of future ironmaking processes is good news for both steel manufacturers looking to cut costs and for the
Depending on the process, the sulfur content in pig iron can be reduced to up to 0.001 %. The largely desulphurised pig iron is further processed in the steel mill itself. If it is not an integrated steelworks, the pig iron may have to be transported several kilometres from the smelter to the steel mill.

The most common process is the use of a blast furnace to produce pig iron which is about 9294% iron and 35% carbon with smaller amounts of other elements. Pig iron has only limited uses, and most of this iron goes on to

Step 1. Fill a crucible with pig iron and carbon. Carbon can be made from charcoal or charred organic material such as bone or wood. The final carbon content of the steel is nearly impossible to predetermine, but filling the crucible threequarters full with steel and the rest carbon is a good start. Video of the Day.
While pig iron may be the more economical input, technically and ecologically speaking, scrap iron is a far superior raw material. Products produced in modern foundries in developed countries
