Iron processing | Britannica

Direct reduction, in which iron ores are reduced at temperatures below the metal’s melting point, had its origin in such experiments as the Wiberg-Soderfors process introduced in Sweden in 1952 and the HyL process introduced in Mexico in 1957 Few of these techniques survived, and those that did were extensively modified Another alternative iron-making method, smelting reduction, had its

Conditions for Minimizing Direct Reduction in Smelting

However, less pre-reduced iron ore can induce direct reduction in a melter-gasifier, which can increase coal ratio In this case, the direct reduction ratio is determined by the reducibility of Pre-Reduced Iron ore (PRI) and the reactivity of coal with CO 2 PRI was made into pellets and its reducibility was measured in various temperatures and H 2 contents Coal was carbonized in melter
