Replacing the blast furnaces with an electronic blast furnace

That’ll be electric arc furnace….

  1. “Electronic” is specifically by the controlled interaction of electrons, not by their transformation into a form of heat energy (heat, light, motion). I’d be amazed if somebody managed to melt iron without heating it.

    Checks link. Wow, not even Gruniad scribblers.

  2. Just for shits and gigs, I was reading about the history of the Bessamer process.

    The past is a foreign country, but rarely more foreign than when you read about how the industrial revolution happened in this country.

    So, when a 19th century entrepreneur wanted to build a new Bessamer converter, they… just went and built one.

    No hordes of feral lawyers, bureaucrats, government jobworths of all descriptions, NIMBY MP’s, or posh retards opposed to all forms of economic growth to make it 1000% more expensive and take years to get permission.

    Imagine that.

  3. Steve, it was a bit of a shitty process. Drive past the Catcliff junction on the M1 in Sheffield for a very faint approximation to the vapours.

    You really think so?

  5. The demise of coal-based industries on Teeside led to lots of complaints from the growers of roses. Coal smoke kept various rose blights at bay. It must surely – he said, cruelly mimicking fashionable dolts – therefore have been good for humans too.

  6. I could be wrong here as my Chemistry A level was 52 years ago, but am I right in saying we can no longer make steel from iron? Since we no longer have blast furnaces and can’t mine coke aren’t they essential?

  7. Well, we can no longer make the pig iron, that’s the blast furnace. The next step, iron into steel – a basic oxygen furnace, or Bessemer – I dunno. I have a feeling, but it’s a feeling only, that there are smaller scale possibilities there. Not necessary to have the whole fuck off millions of tonnes plant. But again, a guess.

  8. Bessemer converters became economically obsolete when the open-hearth process was developed.
    But you cannot run an open-hearth on 100% pig iron (from a blast furnace), you MUST use a proportion of scrap steel.
    Bootstraps.
    You can only use an open-hearth in a steel economy, but once you do, you cannot go back to Bessemer converters.
    Red Queen: “Your move!”
