Raw materials for iron making
WebModern iron making. Iron is manufactured in a blast furnace. First, iron ore is mixed with coke and heated to form an iron-rich clinker called ‘sinter’. Sintering is an important part of the overall process as it reduces waste and provides an efficient raw material for iron making. Coke is produced from carefully selected grades of coal. http://www.madehow.com/Volume-4/Cast-Iron-Stove.html

Dust output in sintering process accounts for about 2% to 3% of the sinter production, while dust and sludge from iron making and steel making process respectively take up 3% to 4% of hot ...
WebSep 25, 2024 · Iron-making. This is the first step in the manufacturing of pure steel. In this step, the raw materials like iron ore, coal and lime are melted in a blast furnace. This results in the formation of molten iron, also known as hot metal, which still contains 4-4.5% of carbon and other impurities, which makes it brittle. WebMaking cast iron. 1 Iron ore is dug out of the earth in surface mines. The ore is obtained in lumps ranging in size from more than 40 in (1 m) in diameter to less than 0.04 in (1 mm) in diameter. To produce cast iron or steel, the lumps must be 0.3-1 in (7-25 mm) in diameter. Lumps of ore, which are too large, are crushed and pass through ...
