Charcoal is considered the least desirable fuel when blacksmithing. While readily available, charcoal may not even reach the necessary temperature to soften iron and steel without a lot of fuel and constant airflow. You can burn through a lot of charcoal quickly and still not achieve the proper temperatures.
Can you use charcoal for a forge?
Charcoal has much more carbon than normal wood (hence the black color) and is a much more efficient fuel source for a blacksmith forge. Charcoal will burn longer and hotter than normal wood and is comparable with coal as a fuel source – more on coal later. Charcoal was the fuel of choice for centuries of blacksmithing.
What is the best fuel for a forge?
How hot will a charcoal forge get?
According to “Marks’ Standard Handbook for Mechanical Engineers”, 10th, coal gas burns at about 3,590°F (1,977°C) under 100% air conditions. More or less air will decrease the temperature. This means that the maximum temperature of a coal fire in a forge is about 3,500°F (1,927°C).
How long does coal last in a forge?
It really depends on your forge setup. My last forge was pretty small and one 50# bag would last me over 2 months, just forging on the weekends.
Can you forge steel with a wood fire?
You are extremely unlikely to ever get the iron or steel to white heat and extremely extremely unlikely to ever get near welding heat. Even if you did the wood as fuel does not burn enough oxygen out of the air to prevent an oxide forming that will prevent a proper forged weld.
What burns hotter charcoal or wood?
Charcoal has an energy value of around 29 MJ/kg, in other words charcoal burns hotter than wood, but when not insulated or not receiving sufficient air supply (including secondary air), the absence of flames or fast flowing CO2 gases will result in less efficient cooking due to a lower heat transfer efficiency (HTE).
Does Coke burn hotter than coal?
Coal is a shiny, black fossil fuel that contains impurities, emits smoke when burned, and produces less heat than coke. Coke is a dull, black byproduct of coal that burns hotter and cleaner. … However, blacksmiths still rely on coke as an efficient source of fuel for the forge.
How much coal does a forge use?
How much coal do you need? Bit of a tricky question! This of course depends on how much forging you will be doing. If you are doing an afternoon of forging then 20 pounds of hardwood lump charcoal should be plenty and 5 pounds of coal should do.
What is better gas or coal forge?
Gas burns cleaner than a coal forge and is readily available. Some of the drawbacks to using gas is that it’s noisier, and it makes the shop hotter in the summer time. Depending on the type of smithing that your doing gas is also generally considered more expensive than coal.
What is the hottest Forge?
The hot forging manufacturing process is performed at extreme high temperature (up to 1150 °C for steel, 360 to 520 °C for al-alloys, 700 to 800 °C for cu-alloys).
Can you melt steel with charcoal?
The easiest way to melt metal into liquid is to heat it in a small, enclosed vessel that is heated from below. You can make your own using a small empty propane tank or metal bucket, plaster of paris, sand, metal pipe, charcoal briquettes, and a steel can.
At what temperature can you forge steel?
If the temperature of the steel is too high, then “burning,” or incipient grain boundary melting, of the steel can occur. While typical hot forging temperatures are between 2150°F and 2375°F – well below the melting temperature of more than 2500°F – deformation (adiabatic) heating results in local heating.
What is the best coal for a forge?
How hot does a forge get?
The result is coke, a fuel that is almost entirely carbon allowing us to reach temperature of 3,000 to 4,000 degrees Fahrenheit at the core of the fire!
