The forge may be the heart in the blacksmith’s shop. It’s within the forge the blacksmith heats metal until it reaches a temperature and becomes malleable enough for him to use his other equipment to shape it.
The traditional blacksmith’s forge has developed and be more sophisticated as time passes, though the principles remain unchanged. The commonest forge may be the one fired by coal, charcoal or coke. The forge is really a specially designed open fireplace the location where the temperature can be controlled so that the metal is heated on the temperature the blacksmith wants, depending on what he offers to do – shaping, annealing or drawing. The there main elements of the forge are:
· The hearth the place that the burning coke (or any other fuel) is contained and over that your metal is placed and heated.
· The Tuyere the pipe leading in to the hearth in which air needs. The effectiveness of the hearth and also the heat it produces is dependent upon the volume of air being fed with it through the Tuyere tube.
· The bellows will be the mechanism where air needs from the Tuyere tube in the hearth. While earlier bellows were pumps operated by muscles power, modern forges have high power fans or bowers to force air in to the Tuyere
The blacksmith adjusts a combination of air and fuel from the hearth the make the exact temperature necessary to heat the metal. A conventional blacksmith’s forge will have a flat bottomed hearth with all the Tuyere entering it from below. The main from the fire is a mass of burning coke during the fireside. With this in mind burning coke will be a wall of hot, but not burning coal. This wall of coal serves two purposes. It provided insulation possesses and focuses the temperature of the fire with a limited area, allowing the blacksmith to heat the metal in the precise manner. The coal also becomes transformed in coke which can then be part of fuel to the hearth.
The outer wall from the fire consists of a layer of raw coal, which is often kept damp in an attempt to control the heat from the inner layer of hot coal so that is may slowly "cook" into coke.
How big the hearth and also the heat it generates may be changed by either adding or removing fuel from it also and adjusting mid-air flow. By changing the form with the outer layers of coal, the contour of the fire can also be modified to match the contour of the metal piece being heated.
Many modern blacksmiths use gas forges. They’re fueled by either gas or propane. The gas is fed into the hearth, which is lined by ceramic refractory materials, and mixed with air and ignited. The pressure where the gas has been fed in to the hearth could be adjusted to alter the temperature. While gas forges are simpler to use and need less cleaning and maintenance, the disadvantage is, unlike a coal fired forge, the contour with the fire is proscribed and will not be changed to suit the design and height and width of the metal being heated.
