- The furnace from cold melts 14kgs of iron in about 50-60 minutes. The video shows the mold making process, melting and final shakeout. The flywheel was made for a model steam engine and other parts for various projects I had on the go at the time.

Glad you liked the video. I will post some more videos on other iron melting furnaces.
Very nice! You should put some cardboard between the crucible and plinth so the two don't stick. It burs away and leaves carbon there.
@Sreemetals About 30 melts of cast iron and in that time I have melted about 500 kgs of cast iron. So the lining will last for years for my limited use. I have tried many types of refractories castables etc and cast iron is hard on all of them. Ceramic fiber heats up very quickly so cast iron melts quickly.
That iron sure pours nice!
@Sreemetals The furnace casing is an old hot water heater. I made a homemade oil burner and the blast air comes from a vacuum cleaner. The refractory is kaowool ceramic fibre.
@BYMetalCaster The burner atomizes most of the oil the furnace vaporizes the rest. I use Kaowool so the furnace heats up very quickly.
This is the problem with youtube it is a worldwide thing and what I use is may not be available everywhere. I love using kaowool for melting cast iron because it heats up so fast but you cannot use with out a coating! I now use a coating called Zircoat W it is far cheaper than J coat but is not available in the US. I have heard of ITC-100 and backyard casters using it on their furnaces but I have not tried it. All I can say is try some and see if it works
even in ancient times channellocks were used as hammers.
Man, i wish there were more people out there who did "backyard" melting of iron and steel. It's not something you see much of.
Thanks for details. Have you coated the surface of wool with harder refractory to avoid erosion due to flame?
@Sreemetals I use 40mm thick kaowool as the hot face and 50mm of gannister.
@Sreemetals Thank you very much .
oh and nice crucible pourer
hope you don't mind the question.. but do you preheat the oil before you send it in the furnace?
didn't mean for that comment to come out the way it did! I thought it looked more like bronze, not that it makes any difference,it's obvious Rourke are Avery gifted foundry man. . would have loved to have that car when I was 20years old or something, pouring iron with a hand ladle 6 days a week.
@Sreemetals I use a product put out by thermal ceramics called "J" coat.
@Sreemetals What is the thickness of lining? Your Pouring system (trolly) is very nice.
Thank you very much. We are running gas fired furnaces for melting Copper alloys. These furnaces are home made. We have not tried Cast Iron in these furnaces because of lower lining life. What is the life of ceramic wool blanket for melting CI.
What is that black powder used in the mold?
Temperature is very good. Please provide details of furnace
where are the typical sparks for cast iron?
Check out Alloy Avenue forum plenty of iron casters there
how did you make the Furnace to use oil and diesel?
Have a look at my video rebuilding this furnace. th-cam.com/video/MgsU5EibFbA/w-d-xo.html
Damm speel check. ..
Please sketch the burner drawing of your furnace
Cast aluminum ? Doesn't look like iron.
That’s iron buddy
giday good job im gonna upgrate to cast iron melting but if that is concrete I see you are a fool, work on sand
cheers, rob
But but but but but but....... Jetfuel can't melt steel beams. Awwwwww, what about all the conspiracies then?
the planes didnt have forced air burners on them either. on top of the fact that the steel beams wouldve just carried away the heat
40+year foundry man this ain't iron...
Dwighte Check that is iron
