Shot of the exterior of a blast furnace. Graphic illustration of Hot Blast Stoves, Exhaust Stack, Charging Gear and Blast Furnace. Coke Iron Ore and Limestone is put into the blast furnace. Hot air is pumped from the stoves into the blast furnace, gas is released. Animation of the processes. Slag and iron are produced. Shot of piles of limestone, iron ore and coke. Large containers of this raw material are transported to the furnace.
Graphic animation of raw material being poured into the furnace through gas tight "bell" valves. Bustle pipe and tuyers are labelled on the diagram. Animation of the smelting process. Slag and iron tap-holes are labelled on diagram. Men at work at the base of the furnace. We see hot slag pouring out of a tap-hole. Flames come off the hot substance. We see it pouring into a large vat. Men work close to the steam. The iron is tapped in the foundry. Rivers of hot liquid metal are seen. Many men work. Iron pours out of tunnels into large vats. Moving machinery. The vats are transported on wheels. The molten iron is cast into "pigs". The iron is poured into moulds. Inside the foundry, lots of steam. Pig iron in piles.

This video is far better than any modern I've sought about this topic.
Thank you for this very clear explanation . After watching the demolition of the Redcar blast furnace it's nice to understand how the plant worked. My grandfather was a blister but sadly he died before I was born. So I never got the chance to speak with him. It must have been like working in the pit of hell. Much respect to the brave men who did this very dangerous work 👍
Blister steel maker? Legend! Some of the toughest workers in those places dude. You better believe he was a strong back for sure!
Stopped by sloss furnace In Birmingham. Thank you for this video.
fascinating that this is a continuous chemical reaction and can run for 100 days if you keep feeding it the raw materials.
Thank you for uploading this.
Excellent film.
Awesome, very well explained!
wish I knew how work these plants and beyond easy breezy
This video shows how blast faces work
That was an excellent film and very accurate. However what it couldn't convey was the heat, the smell, sweating men dragging heavy equipment, white hot sparks flying, the crashing of rail trucks all very dramatic.
Talk about some hard working guys at those plants. Tough and brave.
Engage Time Machine.
Go back and buy these guys a beer!
I worked at u.s. steel a long time ago. 65 to 83. I worked on the blast furnace from time to time. It all looks very familiar. However, the one big difference is the old film none of the men are wearing any kind of safety equipment whatsoever. That was kind of shocking.😮
Did you work at Gary Works?
Reminds me of BSC.corby.
What is the term or word you used for close slag holes? Can you spell?? I do not understand
Dolly I believe
@@flavioaraujo3995 The term we used was 'plugged' or 'stopped' and the device used 'clay gun'
1950 videos put modern youtubers to shame ahah
Good film however how the furnace was charge very over simplified, on the large blast furnace I worked on four charges of coke or ore were dropped onto the large bell (term used for the two seals ) then the space between the small and large bell was pressurised to the same pressure as the inside of the furnace this allowed the large bell to open once this was done the space between the two bells was 'relived' thus allowing the small bell to open. The pressurisation sequence of the blast furnace was very important to the operation of the furnace and I,m surprised it was skipped over ! I said at the beginning 'four charges of coke ' this could vary on the condition of the furnace some times the charging sequence would be changed to 6 and 2, 6 of coke 2 of ore the changing of the charging sequence was a little complicated requiring an electrician (me on my shift) to enter the control room and physically change over the programming switches and only when the next charge was to be coke and the left hand skip was at the bottom.On one occasion not on my shift I must add the change was made with the right hand skip at the bottom resulting in a few tons of coke being deposited where the left skid should have been and this was a hard and laborious job for the furnace hands that did the digging.
Does anyone else think 'Harry Enfield' listening to this?
