Process through Multiscale Process Modeling

3. Shaft Furnace Model 3.1. Previous Works The shaft furnace (Figure 2) is the core of the DR process. Iron ore pellets are charged at the top, descend due to gravity, and encounter an upward counter-flow of gas. The reducing gas (CO and H 2, plus CH 4, CO 2, and H 2O, at about 950 °C) is injected peripherally at mid-height and exits at the top.

MIDREX® Process - Midrex Technologies, Inc.

04-05-2021  The shaft furnace is where iron ore is converted to metallic. Iron oxide, in pellet or lump form, is introduced through a proportioning hopper at the top of the shaft furnace. As the iron ore descends through the furnace by gravity flow, it is heated, and the oxygen is removed from the iron ore (reduction) by counterflowing gases that have a high H ₂ and CO content.

Pathways to decarbonisation episode two: steelmaking ...

Coal in the form of metallurgical coal and pulverised coal act as the active agents or ‘reductants’ that strip away oxygen from the iron ore to yield metallic iron. With temperatures inside the blast furnace reaching over 2000°C, the resulting metallic iron melts and the liquid hot metal is ‘cast’ from the furnace and transported to the basic oxygen furnace.
