  • C.I CASTING IN Cupola furnace PART-1

    Cast iron is made by re-melting pig iron, often along with substantial quantities of scrap iron, scrap steel, limestone, carbon (coke) and taking various steps to remove undesirable contaminants. Phosphorus and sulfur may be burnt out of the molten iron, but this also burns out the carbon, which must be replaced. Depending on the application, carbon and silicon content are adjusted to the desired levels, which may be anywhere from 2–3.5% and 1–3%, respectively. Other elements are then added to the melt before the final form is produced by casting

I began by fanning a fire with a piece of bark to increase its temperature. It is this basic principle I improved on throughout the project. Next, I made a rotary fan from two pieces of bark that slot together at right angles to each other to form a simple 4 bladed paddle wheel about 20 cm in diameter and 5 cm tall. The blades of the fan were not angled and were designed only to throw air outwards away from the axle when spun. The rotor of the fan was made by splitting a stick two ways so it formed 4 prongs. The fan was then inserted into the prongs and the end las...

This is really dangerous, the molten iron can go right through just about anything. Start with aluminum before going up to iron. The fumes are bad, the heat will melt flesh, the fuel tank could explode the crucible could rupture, the pour could hit water. You really need to be careful

After seeing the concept, I couldn't find any information anywhere on the internet or in libraries about arc furnace experiments, so I set out on my own to achieve these results. WARNING: Risk of electric shock, fire hazards, and toxic fumes depending on what material you're working with. Dust from refractory brick should never be inhaled, as it can damage lungs and cause long term respiratory challenges. This project can reach temperatures in excess of 3,000ºF (1,648ºC) which is well beyond the melting point of hobbyists. Caution, care and expert planning are required to mitigate risks. Have fun, but always think ahead, and remember that every project you try is at your own risk. Project History & More Info: If you're wondering where you can get fire brick locally, try a quick Google search for “refractory materials” in your city. I called a couple of companies near me and asked if they'd sell to the general public. All of them said yes. If you can't find anything locally, try searching major hardwares stores online. They usually have inventory online that they don't carry in the stores. The insulating fire bricks I got were the 3” x 4.5” x 9” Alumina-Silicate Brick variety. I got a box of 10 for $33, effectively making them around $3.30 each. I went one step further and designed the furnace so that 2 of them could be made from one brick, cutting the cost in half, making each furnace a pro-rated $1.65 each! They're extremely lightweight, and capable of withstanding the temperatures used in steel working, but soft enough you can cut and carve them with kitchen utensils if you need to. In reading and studying history a bit, I learned that some of the earliest forms of light were made using carbon arc lighting. Large amounts of electricity were pumped through carbon rods, making a bright arc and providing light. To scavenge carbon electrodes, I took a lesson from NurdRage (youtube.com/NurdRage) a couple of years ago I saw his video on what could be scavenged from a carbon-zinc lantern battery (http://bit.ly/IBNurdRageBattery). It's useful to know what common everyday materials are made of, and these heavy duty batteries are containers packed with carbon rods, zinc metal, and manganese dioxide. I tucked the information in the back of my mind until now. In this project I tried melting the zinc casings from the lantern batteries, and casting them into a small ingot, formed with a mini muffin tray. Be cautious of the zinc oxide fumes produced. I haven't personally suffered any ill effects from working with it, but some people claim it can give flu like symptoms, or a fever if inhaled in large quantities. Zinc has a relatively low melting point 787.2°F (419.5°C), so the Arc Furnace is able to melt each casing into liquid zinc in around 5-10 seconds. That's amazing! I don't have an exact purpose for the zinc yet, but it's an easy metal to work with, easy to cast, and great to have on hand for a future projects. It's also one of the main metals used for making a simple carbon-zinc battery. The black stuff pulled out of the battery casings is manganese dioxide. It's a useful chemical for experiments with hydrogen peroxide, so it's worth hanging onto. Although I haven't verified it, I believe any stick welder can be used to power the mini arc furnace, and for most hobbyists, that would definitely be the easier and safer way to go. I just don't own a welder, so I used the one I made instead. You can see how to make it here: http://bit.ly/ARCWelder The longest I've run the unit continuously is around 3-4 minutes, and the electrodes get so hot at that point they can seriously burn your hands, or melt your gloves. I wouldn't recommend running it any longer than that.

I invented the Bow Blower, a combination of the bow drill and forge blower to make a device that can force air into a fire while being easy to construct from commonly occurring natural materials using only primitive technology. I began by fanning a fire with a piece of bark to increase its temperature. It is this basic principle I improved on throughout the project. Next, I made a rotary fan from two pieces of bark that slot together at right angles to each other to form a simple 4 bladed paddle wheel about 20 cm in diameter and 5 cm tall. The blades of the fan were not angled and were designed only to throw air outwards away from the axle when spun. The rotor of the fan was made by splitting a stick two ways so it formed 4 prongs. The fan was then inserted into the prongs and the end lashed to hold it in place. Spinning the fan rotor back and forth between the palms of the hands fanned the fire. But only some of the wind generated by the fan reached the fire. The rest of it was blowing in other directions, effectively being wasted. So I built a fan housing from unfired clay to direct the air flow into the fire. This was basically an upturned pot with a hole in the top, a spout coming out of the side. The housing was about 25 cm wide and 8 cm tall. The hole in the top and the spout were both about 6 cm in diameter so that the air coming in roughly equalled the air coming out. The base of the fan rotor sat in a wooden socket placed in the ground to make it spin easier and the top of the rotor protruded from the hole in the top of the housing. Now when the fan spun, air entered the hole in the top of the housing and exited the spout in the side. Importantly, it doesn’t matter which way the fan spins, air always goes into the inlet and out the spout. Air is thrown out towards the walls of the housing and can only leave through the spout while the vacuum in the centre sucks new air into the housing through the inlet. A separate clay pipe called a tuyere was made to fit over the spout to direct air into the coals. This was done because the pipe that touches the fire can melt away so it’s better to make this part replaceable. Instead of making a large wheel and belt assembly to step up the speed of rotation, I opted for a 75 cm long bow. I made a frame to hold the rotor in place consisting of two stakes hammered into the ground with a socketed cross bar lashed on to hold the top of the rotor. I made bark fibre cordage and tied the end to a stick. I then looped the cord around the rotor and held the other end in the same hand holding the stick. I then pushed and pulled the bow causing the rotor to spin rapidly, forcing air into the fire. I made a simple mud furnace for the blower. Then I collected orange iron bacteria from the creek (iron oxide), mixed it with charcoal powder (carbon to reduce oxide to metal) and wood ash (flux to lower the meting point) and formed it into a cylindrical brick. I filled the furnace with charcoal, put the ore brick in and commenced firing. The ore brick melted and produced slag with tiny, 1mm sized specs of iron through it. My intent was not so much to make iron but to show that the furnace can reach a fairly high temperature using this blower. A taller furnace called a bloomery was generally used in ancient times to produce usable quantities of iron and consumed more charcoal, ore and labour. This device produces a blast of air with each stroke of the bow regardless of whether it is pushed or pulled. The bow makes it possible to operate the blower without using a complicated belt and wheel assembly used in traditional forge blowers. There is a brief pause at the end of each stroke where the fan stops to rotate in the other direction, but this is effectively no different to the intermittent blast of a double acting bellows of Europe or box bellows of Asia. The materials used (wood, bark, bark fibre and clay) are readily available on most continents. No leather, valves or precisely fitted piston gaskets are required as with other types of bellows. The cords for this device wear out often so a number of back up cords should be kept handy for quick replacement. In summary, this is an easy to make device that solves the problem of supplying forced combustion air required for high temperature furnaces and forges.
