RE:Direct reduction

RE:Direct reduction Again...

All iron ore has to eventually be "reduced"  -- removing of the oxygen -- in order to be turned into steel or iron.

it is a chemical process.

But this happens during the steel making process, not during the pellet making process.

Tradtional or primary steel making uses coal and coke during the smelter phase at high heat to mix with the ore pellets, causing combustion, and forcing out oxygen.

Direct reduction steel making is essentially the same high heat process, but uses hydrogen or natural gas to do the same, instead of coal or coke.

None of these have anything to do with pelletization, and both require pellets that are baked during an induration phase.

this new procedure eliminates coke and uses gaz instead in the pelletisation of iron if i understood anything at least .
 


iron pelletization 
 

not plug and play after all
