A groundbreaking method for steel production in China : 3,600 times faster, with no coal involved

For centuries, steel production has relied on coal-powered blast furnaces, a slow and highly polluting process. Traditionally, iron ore is crushed, heated, and mixed with coke (a refined form of coal) inside furnaces at extreme temperatures, taking hours to complete.
Now, researchers have found a way to reduce this process to mere seconds. Instead of relying on coal-based reactions, they use ultra-fine iron ore powder, injected into a high-temperature furnace through a specialized vortex lance. The result? A near-instantaneous chemical reaction, producing molten iron in just a few seconds.
According to Professor Zhang Wenhai, the lead scientist behind this breakthrough, the new method allows steel production to be completed in just 3 to 6 seconds—compared to the 5 to 6 hours required in conventional blast furnaces.
Well, we also have thermite, but it’s somewhat messy and dangerous. I guess this might be better.
Meanwhile, America is digging a ditch back to the 18th century. Let’s set up a metal smelt on El Capitan!
I wonder if this works to scale. I see no reference of volume in the article. Does it turn a hundred tons of ore into steel 3600 times faster in the same/similar space? Or does it need a ton more space?
The claim seems highly optimistic and I’m a bit skeptical but if it’s truly this crazy, then that’s nothing but good for the world of industry.
An article from the series – a scientist raped a reporter. A bunch of verbal garbage about nothing.
Looks like click bait.
Why the „3,600 Times Faster“ Claim?
The specific figure likely stems from a misunderstanding or exaggeration of experimental lab results. For example:
– A 2023 study in Nature described an electrochemical process that accelerates iron ore reduction by orders of magnitude in controlled settings.
– FeastMagazine (or other outlets) may have cited preliminary research or speculative claims without peer-reviewed validation.
What’s the difference from the SSAB method? https://www.ssab.com/en/fossil-free-steel/ssab-zero/the-road-to-sustainable-steel
There isn’t any discussion of how much energy it takes to pulverize the iron ore for it to be used in this process.
I wonder if this another China lie.
It sounds rather wild.
I’ve been after this article for months yet no paper has been published about this in any magazine nor the magazine refered. But what I see is a lot of news with the same content that sources each other and always end at Non-ferrous metal magazine which has not the said paper…
But isn’t China’s electrical grid mostly coal powered? They just moved the energy to a different place didn’t they?
the steel plant near my house that is in mesa az is electric arc furnace setup. a whole lot of rebar coming out of it. LOL.
If it used dramatically less energy, wouldn’t that be the headline instead of the speed?
Pulverize something that likes to oxidize, how do you keep that from happening? Anybody ever seen a wood dust explosion?
And the U.S. uses electric arc furnaces and recycles scrap steel without needing coal. Been like this for decades. Blast furnaces are an old technology.
Furnaces can turn 350 tons of iron into steel in 40 minutes, if i am mathing right 3600 times faster then 40 minutes is huh, 40 seconds.
Big if true
Cross post this to r/Pyongyang and hear what the free people of DPRK think. DPRK groundbreaking method for steel production produces more, better steel AND breaks more ground.
This sounds incredibly fake/too good to be true.
This was posted since last year December. Every article on this that I found has the same thing copy pasted with minor changes. 0 sources in any of them, seems like the usual click bait copy paste work freelancers love to do for these online magazines. Basically just spam meant to get some clicks and that’s it.
The no coal is kind of a lie, it still needs energy, a lot of it, and most of china’s energy still comes from coal.
Time was never a concern, you can make 150 ton of steel in 90 minutes with a single arc furnace
