General Info Relating to Blacksmith Forge

The forge may be the heart of the blacksmith’s shop. It is in the forge the blacksmith heats metal until it reaches a temperature and becomes malleable enough for him to work with his other equipment to shape it.
The regular blacksmith’s forge has evolved and be more sophisticated over time, however the basic principles remain unchanged. The commonest forge will be the one fired by coal, charcoal or coke. The forge is really a specially engineered fire place where the temperature may be controlled so that the metal is heated on the temperature the blacksmith wants, determined by what he offers to do – shaping, annealing or drawing. The there main parts of the forge are:
· The hearth where the burning coke (and other fuel) is contained well as over which the metal is put and heated.
· The Tuyere the industry pipe leading in to the hearth whereby air needs. The strength of the hearth along with the heat it generates is dependent upon how much air being fed with it with the Tuyere tube.
· The bellows include the mechanism in which air needs with the Tuyere tube into the hearth. While earlier bellows were pumps operated by muscles power, modern forges have high power fans or bowers to force air in the Tuyere

The blacksmith adjusts the mixture of air and fuel from the hearth the generate the exact temperature required to heat the metal. A conventional blacksmith’s forge will have a flat bottomed hearth using the Tuyere entering it from below. The main from the fire will be a mass of burning coke down the middle of the fireside. With this in mind burning coke is a wall of hot, and not burning coal. This wall of coal serves two purposes. It provided insulation and has and focuses the warmth in the fire to a limited area, allowing the blacksmith to heat the metal inside a precise manner. The recent coal also becomes transformed in coke which could then be harnessed for fuel for the hearth.
The outer wall with the fire is made up of a layer of raw coal, which is often kept damp in order to control the warmth of the inner layer of hot coal in order that is may slowly “cook” into coke.
The dimensions of the fireplace and the heat it makes may be changed by either adding or removing fuel from it as well and adjusting air flow. By changing the shape with the surface layers of coal, the form with the fire can be modified to accommodate the contour from the metal piece being heated.
Many modern blacksmiths use gas forges. They’re fueled by either gas main or propane. The gas is fed in to the hearth, which is lined by ceramic refractory materials, and mixed with air and ignited. The stress where the gas will be fed in to the hearth could be adjusted to alter the temperature. While gas forges are easier to use and require less cleaning and maintenance, the drawback is the fact that, unlike a coal fired forge, the form from the fire is proscribed and will not be changed to accommodate the shape and sized the metal being heated.
