Ironmaking Process - an overview ScienceDirect Topics

2012-4-4  The ironmaking process in the blast furnace is a heat and mass transfer process, and the furnace can be divided into different zones according to physical and chemical state of the feed and temperature. Figure 1.1.5 illustrates various zones of the blast furnace and feed distribution and materials flow [13]. Corresponding to each temperature interval, typical reactions will take place.

The Steel Manufacturing Process - How is Steel Made?

2020-4-10  Afterward, iron went through a final iteration, which most resembles today’s steel material. In India, ironworkers developed an iron smelting process that combined the perfect ratio of iron to carbon. Using crucibles, or clay containers, the ironworkers would blend iron and charcoal pieces together in a high-temperature furnace.

Iron Sponge Process - an overview ScienceDirect

The iron oxide process is one of several metal oxide–based processes that scavenge hydrogen sulfide and organic sulfur compounds (mercaptans) from gas streams through reactions with the solid-based chemical adsorbent (Kohl and Riesenfeld, 1985). They are typically nonregenerable, although some are partially regenerable, losing activity upon each regeneration cycle.
