Enjoyed this film. I'm a Melter/ Operator on an Electric Arc Furnace. We tap 150t every 48/50 mins. No disrespect to you guys but I love watching films like this with the smaller scale stuff. Respect...
Hi, give me your email please. I have a plan to build kupolofen for 200-250 kg per hour and i found your channel some time ago. So i have some questions about your project.
Enjoyed your video and thought it was a really good effort. I did some work in iron foundries too, and my father, grandfather and great grandfather also. I have a notebook of my grandfather's, about 1914-18, hand-written copied notes from a book called The Cupola Furnace by Edward Kirk. (1903) It is quite dated but full of easy-to-read practical know-how and still well worth a look. You can download it from Google. All the best, A
My great grandad started an iron foundry 1865 with home made equipment and self taught. Then my dad and finally me. Environmental friendly cold blast cupola fitted in 1980s didn't stop us having to close due to cheap imports from Poland India and then China. Tough skilled men working confidently in hot dirty conditions. Helped by dad's homebrew probably. One drink each per shift diluted with lemonade to preference. I remember being so hot in the summer I would go outside in a shift and stand in the full summer sun just to cool off! And mum peeling dad's shirt over his head after his shift because it was stuck to his body with sweat and he was too knackered to do it himself. Broke his heart when I had to close it or go bankrupt. We found all the guys new jobs elsewhere before they left with their redundancies. Not a single one spent a day on the dole apart from one who did so through choice . Local politician did sweet FA.
It is interesting that there is belief that a mini cupola can work. I am working on constructing a mini cupola for the production of 50 - 100kg cast iron per hour. Is this possible? If so what should be the size of the cupola furnace?
@@itaizaba4197 Sorry for the late anwser, but yes it should be possible. You could just build it a little smaler than ours, but without putting in so much. The important thing is, that you have to tap it and don't try to let it get running all the Time open. You have to use it discontinuesly (if thats a word). Otherwise you will get problems with your iron temp.
Als erstes mal Respekt was ihr da hin bekommen habt. Was macht der etwas größere Ofen im Hintergrund die Stunde? Ich tippe mal so zwischen 4 bis 8 to die Stunde.
Brauchen wir eigentlich garnicht, da wir ja sowieso schon mit Sauerstoff arbeiten und mittlerweile auch Temperaturen von bis zu 1430 Grad hatten. Mittlerweile liegen wir bei einer Abstichstemperatur von ca. 1400, was für unsere Verhältnisse sehr gut ist, wie ich finde. :) Aber wir haben jetzt ein neues Gebläse und das schafft unmengen an luft mehr als die alten und da denke ich, dass dies völlig ausreichen wird. Aber ist in unserem anderen Video alles besser zu sehen. :D Eure Öfen gehören dann sicherlich nicht zu den kleinsten. ;)
