    Just want you to know my 2 year old is obsessed with "hot metal factories" and this is his favorite video in the world. We have watched this literally dozens of times.......thanks for making this. Please make a sequel.

    In the early 70s I started into industrial electrical maintenance as a Motor Inspector at Colorado Fuel & Iron (CF&I) in Pueblo, Colorado. I 'floated' as a Motor Inspector in over half the mills there. It was very interesting. Imagine watching steel rail being rolled by a 22,500 horsepower steam engine, largest west of the Mississippi River. At night the sky would light up when they were pouring skulls from the ladles. i started out as labor in the Open Hearth and moved into being a Motor Inspector, which was a maintenance electrician.

    I’ve worked in every steel mill between Pittsburgh and Chicago as a union ironworker and I’ve never seen a steel mill that clean. Twenty- seven years in and out of every part of them, and I still wonder what mr. Bessemer was thinking when he saw the violent stuff going on and said, “ yes perfect, just what I was expecting!”

    Steels in aircraft are primarily specialized aerospace grade 304 Stainless steels and Inconel stainless steel. These steels are what makes a jet engine or turboshaft engine. 304 stainless makes up almost 75% of a jet engine turbo core. Inconel makes up 25%and is used in the rear turbine of the jet engine. Inconel is monocrystaline high temperature steel that rivals titanium, and tungsten for dimensional and strength stability at extreme temperatures. Inconel is so good it's replacing tungsten for rocket engine parts. SpaceX is building the world's largest rocket called Starship and it's being made out of a proprietary grade of 304 stainless steel.

    the sintering process is to make pellets out of that ore... in order to have the hot air flow thru that stuff, so that CO can reach that FeO and get the O in order to produce CO2 and FE2 so you can have your molten metal...
    otherwise you jsut have a layer of iron ore (FeO) and nothings gets thru.
    the oxygen is not removed coz it's hot in the blast furnace...
    pls explain it correct, or not at all

    I'm wondering if the heat from the cooling of the finished product is used. It doesn't looks like it is here but it could be, hard to tell. But with some heat exchangers or even turbines, it could be a good way to gain energy efficiency.
    I'm sure many engineers already thought about it and made calculations on that. If it's worth it, it probably already exists.

    Can I ask a question about coke making. When you heat the coal how come it doesn't burn to ash. Apologies if that's a dumb question but it's something that I'm curious about

    • @MetallurgyData
      @MetallurgyData  3 ปีที่แล้ว +3

      Hi, the coal is heated in an air tight oven, so oxygen is excluded (a good comparison is to how charcoal is made) and thus the coal is heated but not burned, the volatile matter is driven off, leaving coke.

    • @flamingfrancis
      @flamingfrancis 3 ปีที่แล้ว

      When coking coal is analysed in the laboratory (or it used to be) one of the analyses performed is for the ash content. So Volatile Matter and Ash are the two significant components of the final product. Ash can be analysed on a spectrometer to determine conformance as an end use product. Coke remains very brittle to compensate for the handling in the transfer to the BF where large lumps are desirable for fluidity of the raw materials.

      Your not wrong there mate I have worked in both types of plant in South Wales and both are horrible places.I’ve heard about people being killed but never been close when it’s happened thankfully. Unfortunately you can only imagine what it would be like working in plants that are in eastern countries where work force or the environment have little consideration we are supposed to be advanced countries and the conditions for us is bad enough but as always you get what you pay for and cheap steel comes at a price be it the payed by the people that work there the environment or both as with all work places I take the view you are in charge of your own safety and look after your self if you find the grim reaper is getting to close best go work elsewhere. Some of these places run out of people so they slowly increase wages to tempt people back and keep working but there’s no point being the richest man in the graveyard.stay safe there’s no second prize in this game

    Well done, but the direct reduction process should be - at least - mentioned.

    i knew there was quite a bit of work; but i didn`t even have a clue. Grandfather and Great -Grandfather were Steel workers.

    Are there alternatives to using coke? I've heard of using hydrogen injection instead, is that viable?

    • @frphxkaboom3008
      @frphxkaboom3008 3 ปีที่แล้ว

      The oxygen in the hot blast combines with the carbon in the coke to form carbon monoxide . Carbon monoxide is the primary reduction agent in the blast furnace. The carbon monoxide combines with the oxygen in the ore to form high carbon iron or pig iron. The carbon monoxide and the carbon dioxide created in the furnace are recycled into the hot blast stoves as a fuel to heat the cold blast. ...so no.

      Scrap doesn't need to be reduced so they use electricity. Oddly enough, they use oxygen to remove the excess carbon from the pig iron in the BOF.

      Hydrogen can make steel brittle. Arc welding rod must be free of water and moisture because the electric arc generates hydrogen which will make the weld brittle.

      @@frphxkaboom3008 BF molten Iron (hot metal) and Pig Iron are two different things. Pig Iron is a product of hot metal when the latter is cast in a Pig Mill. This can also be done by casting the HM into sand moulds but metal moulds are resuable and the Pigs are removed on cooling. It is covered partially in this very good video.
      As it states the majority of HM is used in the BOF but in bygone times when needed some HM could be transferred to a Pig Mill for processing. Beneficial for transportation and also for remelting in Foundaries.
      Think of the volume of CO2 that goes up the stack when 300 or so tonnes of HM at 4.0% C is reduced to steel with 0.10% C
