Introduction to Iron Ore and Steel Smelting Processing Iron ore is obtained in the conventional method of open cast or underground mining and conveying the ore to the surface preparation are where it is crushed, washed, and transported to the smelter
and (ii) Fe losses in the steel making process Growth 2000 -15 Percent 31 33 51 , with the prices of iron ore and coking coal used (to produce hot metal (pig iron)) as scrap , China has emerged as both the biggest producer and top consumer of steel in the world, accounting for about 47 percent of global steel consumption However, the .
To estimate the impact of a change in any main input (iron ore, coal, coke, other steel raw materials, energy, or labour) on the total, fixed or variable production costs of any steel product (semi-finished; or flat, long, or pipe and tube finished steel products) made through either main production process route (integrated steel manufacturing .
Deterioration of raw materials quality: Iron ore and metallurgical coal quality has shown a significant deterioration in quality during the 2000s This has put a huge pressure on the efficiency and the environmental performance of the global steel industry’s raw materials processing operations
Iron ore pelletizing Iron ore fines are agglomerated into pellets and then indurated using a furnace to create iron ore pellets These are typically fed to a blast furnace or DRI plant as part of the process to make steel
In the iron making stage, the blast furnaces are used to convert iron ore, sinter and other raw materials into molten iron called hot metal Hot metal is supplied to the steel melting shops where the process of steel making is either BOF (Basic Oxygen Furnace), OHF (Open Hearth Furnace) or EOF (Energy Optimizing Furnace)
