The question how to forge iron, began to interest the person in an extreme antiquity with the invention of the first instruments of labor. Then the person had thoughts of how to improve qualities of the used metal and to give it the desirable form. Masters 4 millennia BC in Mesopotamia, Iran and Egypt already widely used cold forging for purification of native iron of impurity. And a bit later hot forging which it is possible to call the union of metal and fire, knew already not only in the developed ancient states Rome and Greece, but also in Africa, Asia and Europe. The fact that, having even passed many millennia of evolution is remarkable, forging of iron remains in many respects traditional.
It is required to you
- * horn (or furnace);
- * pig for forging (for example, a piece of fittings);
- * pincers with the long handle;
- * hammer;
- * anvil
Instruction
1. So, as we know, it is necessary to forge iron ""still hotly"", i.e. previously its heating in a horn or the furnace up to the forging temperature. For iron it, for example, is 1250-800os. Metal at a forging temperature gains the greatest plasticity, but does not become excessively fragile.
2. Then previously prepared pincers it is necessary to get preparation and to forge it from the middle by the ends. It becomes to remove emptiness preparation and to bring down scale - burned through, and therefore too fragile layer of metal.
3. Further you start a part creative - to giving to what remained from initial preparation, desirable forms and the sizes. Arm with a hammer and, periodically turning preparation by pincers, reach the maximum perfection of contours. At the same time are not lazy more often to warm preparation - forging at too low temperature leads to cracks in metal!
