Genuinely couldn't use this for a lesson, with that music in. It's almost like a badly mixed track where the vocals sit underneath the instrumental. Great content, awful audio.
Carbon content of steel is not 2 to 4%. It is much lower in most all steel grades. A 2% carbon steel would be too brittle for much use. A 4% carbon would be iron not steel.
I wonder if, with sufficient heat, raw ores could be separated by boiling them into a gas, and then condensing them to a liquid... based on their boiling points. Fractional Distillation of Metals?
3:20 - _"...combustion _*_of oxygen_*_ in the furnace"_ - ??! Or should it be "combustion CAUSED BY oxygen"? People, this animation was supposedly/ apparently produced by Swansea UNIVERSITY! And NOT by "Swansea City A.F.C.", right? Why then such a blunder? Repeat after me: "Oxygen does not 'burn' - it makes other things burn" - and again, "Oxygen does not 'burn' - it makes other things burn" - and again, "Oxygen does not 'burn' - it makes other things burn" - and again... till it gets through. And, oh, BTW - there's one exception, actually - OF2, or oxygen fluoride - NOT fluorine oxide, as in this marriage the fluorine is the "oxidiser" - but still, someone please check the script BEFORE recording the narrative, would ya? And then, 3:33 - _"The oxides combine with the calcium in the quicklime to form their RESPECTIVE CALCIUM OXIDES..."_ ?? But quicklime IS a calcium oxide, CaO, so...? Someone please translate it to plain and factually correct English "can or not"? Jeez... "Which then float on the surface of liquid steel, constituting (...??) constituting molten slag" also sounds like "modern education shining through"... How about "which then, being less dense, float as so-called slag on the surface of molten steel" - ? And then... A nit picking, one may say, but showing white-hot slag and steel as black, "tar-like" goo does strike me as odd, to say the least. How about RED, or bright orange? Huh?
Great video, Thank you, sir!... can you explain how we analyse the tensile data like decreasing or increasing values and the material behavior if we make a comparison
I worked at two EAF shops in NJ for decades. Instead of direct reduced iron, in order to boost the carbon for high carbon grades we added to the steel scrap either coal, coke, graphite or high carbon railroad rails instead. Also, to supplement the arc heat in the cold spots we had oxygen/natural gas burners. Supersonic Oxygen was injected through a lance through the slag door.
@@BackyardBeeKeepingNuevo when I first interviewed for the job as an engineer at the mill, I was asked to come back for a plant tour dressed in clothing I didn't mind getting sweaty and dirty. I did, and was mesmerized watching the arc furnace. I was told a previous applicant did not have a plant tour before he was hired. His first day on the job he was taken into the melt shop and was about 30 ft from the arc furnace at a safe location. When t started arcing it scared the crap out of the guy. He ran out, and immediately quit. My reeacion, on the other hand, was, "That's awesome!" and I was immediately hired.
what if we want to use for dendrites? like eutecitc snBi microstructure and want to study phase size distribution. I'll be really thankful if you could help
Thank you. The metal project finished in June 2023, however, a new project has been set up that continues to deliver distance learning concentrating on net zero skills. The links in the video description have now been updated.
Thank you for the useful video! I have a question, I still don't understand how you determine the yield stress. I'm also working on the discontinuous yielding case; we usually determine it by the lower yield strength. Why in this case you determine the yield stress as the region when it changes from elastic to plastic deformation? Not based on upper yield strength or lower yield strength? Thank you!
Thank you for this! Helped me a lot. Just a question: if you don't have the software you used in the video (i.e. no line to drag with the same angle as the gradient of the elastic region), how can you calculate the elastic + plastic strain to failure using Excel?
Great Video! and Great Efforts Highly Appreciated! May i ask you for the raw data from the machine for 1 ductile and 1 brittle material so i can do the analysis myself ?
Thank you. Awesome video. I have a question, where is the Fixed length line tool located in ImageJ? In my version I do not seem to find it. Do i need a plugin?
