Pure iron is too soft for many usIron from the blast furnace is an alloy of about 96 percent iron, with carbon and some other impuritiIt is hard, but too brittle for most uses, so most iron from the blast furnace is converted into steel by removing some of the carbon
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
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
Blast furnaces are similar to furnaces, but can smelt only ore blocks and tools/armor made of iron, gold or chainmail Once an item and a fuel are placed into the blast furnace, the block state changes to lit and the item is smelted twice as fast as a regular furnace Fuel is also used at double the rate of regular furnaces, so the number of items smelted per fuel stays the same
This page looks at the use of the Blast Furnace in the extraction of iron from iron ore, and the conversion of the raw iron from the furnace into various kinds of steel The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke .
The blast furnace is where bog ore was smelted to create cast iron "pig" bars To do this, three types of raw materials were brought over the charging bridge and loaded into the chimney of the furnace Bog ore is an iron-rich rock that was harvested locally from bogs and similar bodies of water
Blast furnace gas is produced during the iron oxide reduction in blast furnace iron making in which iron ore, coke and limestone are heated and melted in a blast furnace and is an indigenous process gas of the steelworks industry (Pugh et al, 2013)
The pig iron is produced by smelting iron ores in a blast furnace So we can call that the product of blast furnace is pig iron The blast furnace is a chimney like structure made form heavy steel plates lined with fire bricks to the thickness up to 15 meters Its approximately height is up to 30 meters and 9 meters round in the diameter
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 38–47%, along with silica and other constituents of dross, which makes it very brittle and not useful directly as a material except for limited .
Blasts furnaces are used for smelting during the production of metals such as iron, lead, zinc, and copper A blast furnace works by blasting hot air up through the furnace while fuels, limestone, and ore move continuously through the top of the furnace The method used in blast furnaces have been used since the 1500's
