The FINEX Process :: Total Materia Article

The Finex process is an innovative ironmaking process which has been developed by Siemens VAI and Posco. A schematic of the process is shown below: Figure 1: The FINEX process. Molten Iron is produced directly using iron ore fines and non-coking coal rather than processing through a sinter plant and coke ovens as traditional blast furnace route.

THE FINEX® PROCESS ECONOMICAL AND

2020-5-20  Viewing the process from the ore route, a pneumatic conveying system transports the iron ore fines to the fluidized-bed reactor tower. The fine iron ore is then charged to a 3-stage fluidized-bed reactor series. A reduction gas generated in the melter-gasifier flows through each of the fluidized-bed reactors in counter flow to the ore direction.

Finex Process Industrial Efficiency Technology

2017-9-13  Finex is a fluidized-bed smelting reduction process, and is considered to be a more advanced form of Corex process. Its core plant consists a melter-gasifier – which melts the DRI and gassifies the coal – and a series of successive fluidised beds that reduce ore fines to DRI. The technology utilizes fine ore and non-coking coal. Iron ore is first pre-reduced in fluidized-bed reactors

How to Claim Insurance on a Sponge Iron Damaged

2011-6-2  Sponge iron reduced via the rotary kiln method will normally have a lower metallic iron yield than say material yield from a gas based process. Since, normally your hot metal yield will be the metallic iron in the songe iron. As the songe iron reoxidizes, as it did when it got wet, your yield will reduce as well, almost in a linear scale.
