Motor oils and diesel (which have a mix of very long carbon molecules) are suitable for melting iron and stainless. Liquid hydrocarbons like pentane- hexane-septane-octane can get your fire even hotter. Propane has a little higher energy density. Natural gas (methane) has the lowest energy density, but is suitable for melting aluminum and bronze if you aspirate it. If your fire is in a thermally insulated container, the heat has a hard time leaving. If you were to blast highly oxygenated air into that charcoal with something like a leafblower motor, you would burn the carbon very quickly and release all of its heat very quickly. If you have a charcoal fire with no wind or aspiration of any kind, you will just have a gentle campfire, but if you pump oxygen in it (air is about 18% oxygen) you increase the speed at which the carbon oxidizes. Heat generation from reduced carbon sources is a function of both energy density and oxidation rate.

A homemade cast aluminum lathe is one thing, but one with cast iron parts would be even better. It’s an interesting lesson in metallurgy, as well as a graphic example of how not to make a flask for molding cast iron.Ĭast iron from the home shop opens up a lot of possibilities. The furnace itself is quite a thing, running on a mixture of diesel and waste motor oil and sounding for all the world like a jet engine starting up. had to play with the melt, adding lumps of ferrosilicon alloy to get a cast iron with better machining properties than the original rotors. Usually available free for the asking at the local brake shop, he scores them with an angle grinder and busts them into manageable chunks with a hammer before committing them to the flames. The cast iron comes from a cheap and abundant source: car disc brake rotors. The video below shows a fairly expansive shop and some pretty unique tools he uses to recycle cast iron we were especially impressed with the rig he uses to handle the glowing crucibles from a respectful distance. It looks like knows a thing or two about slinging hot metal around. But imagine what you could accomplish by recycling cast iron instead. Not that there’s anything wrong with that there’s a lot you can accomplish by casting aluminum. ![]() SPECIAL CHEMISTRY REQUIRED CONSULT U.S.When it comes to choice of metals that can be melted in the home foundry, it’s a little like ’s famous quip: you can melt any metal you want, as long as it’s aluminum. Casting the ability to produce high-quality steel and iron castings in quantities from a single prototype to a long production run. Our range of casting size, melting capacity, control of core and mold making and availability of various pattern materials give U.S. Patterns are produced in wood, plastic or polystyrene, depending upon customer needs. Our newly expanded and automated molding and core making department produces castings of outstanding dimensional stability and superior appearance. Casting meets or exceeds foundry casting industry standards. Consistent melting practices and constant chemical and physical properties testing of the metal assures that all metal poured at U.S. Flask Sizes available in various sizes to accommodate customer needs.Ī melting capacity of 6,200 pounds per hour is maintained by two new state-of-the-art electric induction furnaces. Casting Company pours a wide variety of carbon, low alloy steel along with grey and ductile iron castings in weights ranging from 10 to 8,000 pounds. ![]() Home » Iron Foundry Casting Capabilities » Steel & Iron Castings Steel & Iron Castings
