Direct Reduced Iron (DRI) Cargo Handbook the world's ...
Iron ore is reduced in solid state at 800 to 1,050 °C either by reducing gas (H2+CO) or coal. The specific investment and operating costs of direct reduction plants are low compared to integrated steel plants and are more suitable for many developing countries where supplies of coking coal are limited. The direct reduction process is intrinsically more energy efficient than the blast furnace ...

Rusting of Iron Explanation, Chemical Reaction, Prevention
Rusting of iron refers to the formation of rust, a mixture of iron oxides, on the surface of iron objects or structures. This rust is formed from a redox reaction between oxygen and iron in an environment containing water (such as air containing high levels of moisture). The rusting of iron is characterized by the formation of a layer of a red, flaky substance that easily crumbles into a powder.
