manufacturing process of iron ore to pig iron blast furnace

Pig Iron and Its Manufacturing Mechanical Engineering

Pig Iron and Its Manufacturing Mechanical Engineering

The molten iron thus produced is known as pig iron. The slag from the blast furnace consists of calcium, aluminum and ferrous silicates. It is used as a ballast for rail roads, mixed with tar for road making and in the cement manufacture. The pig iron from the blast furnace contains 90 to 92% of iron.

This process involves several steps. Iron ore is first mined and then turned into pig iron in a blast furnace, and some rock waste such as silicon dioxide is separated out. In the final step, the pig iron is refined into steel using a process that includes reacting ... reserves were used for pig iron production. (iii) Calculate. the weight (in ...

Further, solid pig iron is used as "pure" raw material and carbon source in EAFs. The blast furnaceBOF route produces almost 66% total crude steel, and EAF route accounts for about 31%, while the blast furnaceopen hearth process, which dominated steelmaking in the first half of the 1900s, had only a share of about 3% left [7].

Before the iron became cold, the pigs were separated from the sow and the latter broken up into smaller pieces. It required about 2 tons of ore, 1 to 2 tons of charcoal, and a few shovelfuls of limestone to make 1 ton of pig iron. The average furnace produced some 500 tons of such iron a year.

The slag produced at blast furnace during pig iron manufacturing is called blast furnace slag. The slag produced at steel melting shop is known as steel slag. Slag output obtained during pig iron and steel production is variable and depends mainly on composition of raw materials and type of furnace. Typically, for ore feed containing 60 to 65% ...

Blast furnacebasic oxygen furnace (BFBOF): This is the dominant steel production route in the iron and steel industry, involving the reduction of iron ore to pig iron in the blast furnace. BFBOF operation relies almost entirely on coal products, emitting ∼70% of CO 2 in the integrated plant (BF iron making). Hot iron is then charged to a ...

Integrated Blast Furnace (BF) and Basic Oxygen Furnace (BOF) A blast furnace is the first process in manufacturing steel from iron ore, which is mined. Blast furnaces heat purified coal, or "coke," limestone, and iron ore, then inject it with oxygen to reduce the carbon content and remove impurities. Electric Arc Furnace (EAF)

A small community, the first site of the town of Munising, sprang up around the furnace. The furnace first went into blast on June 28, 1867, and within a year was producing up to twenty tons of pig iron each day. The smelting process relied on a variety of resources and transportation networks to produce the finished product. Iron ore was mined ...

Today, no one process is solely used to process steel. A blast furnace processes most iron ore, creating pig iron. The basic oxygen process is used to create steel using the pig iron and electric arc is used to produce steel from plentiful scrap, although either method can process pig iron or scrap iron.

Modern steel mills and directreduction iron plants transfer the molten iron to a ladle for immediate use in the steel making furnaces or cast it into pigs on a pigcasting machine for reuse or resale. Modern pig casting machines produce stick pigs, which break into smaller 410 kg piglets at discharge. References

The pigiron is then brought to the steel mill either in liquid form or as cast iron slabs. Often the blast furnaces are directly connected to a steelworks, so that the molten pig iron can be brought directly to the steelworks by rail. In some cases, however, large pig iron ingots are first cast and transported to the steelworks.

The high alumina content in the iron ore poses a major challenge in blast furnace operation. To maintain appropriate slag viscosity, plants practice the addition of quartz and correspondingly the addition of lime to take care of basicity . This results in a significant increase in the slag rate for Indian blast furnaces (375420 kg/ton of hot ...

This way, as we know that the value of C is 475 kg C t −1 pig iron, we obtain a value for the blast furnace gas of 2210 kg BFG t −1 pig iron. To know the volumetric flow (Nm 3) in standard conditions of the blast furnace gas (BFG), it is necessary to know that the weight of the blast furnace gas mol (25% CO, 20% CO 2, and 55% N 2) is ...
