· In the gas based reduction processes, a vertical shaft kiln is used in which iron ore is fed into the top of the kiln and finished sponge iron is drawn off from the bottom after cooling it so as to prevent its reoxidation. The reducing gas is passed through the ore bed, and spent gas is recirculated after heating and reforming to a mixture of H2 and CO in a reformer, where it is also heated ...

iron processing iron processing Iron making: The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way.

· Iron ore and steel prices in several regions around the world have been falling in August, potentially signaling some softness in what has been a historically pricey ferrous scrap market.. Steel production cutbacks in China's blast furnace/basic oxygen furnace (BF/BOF) steel industry sector are being cited as the lead factor in falling iron ore prices.

In the BOF process, coke making and iron making precede steel making; these steps are not necessary with an EAF. Pig iron is manufactured from sintered, pelletized, or lump iron ores using coke and limestone in a blast furnace. It is then fed to a BOF in molten form along with scrap metal, fluxes, alloys, and highpurity oxygen to manufacture steel. In some integrated steel mills, sintering ...

The process reduces iron ore using a reforming gas made from natural gas. The DRI is used mainly as the raw material for electric arc furnaces (EAFs), as a clean iron source substitute for scrap iron. Pores are left behind in the DRI after oxygen has been removed. These pores, if filled with water, for example, can cause the iron to reoxidize with ambient oxygen, generate heat and occasionally ...
