How Iron Powder Is Made
There are various ways to make iron dust. In the past, it was made by engineers and teachers, and it took a lot of effort.
In the beginning, iron was mined in the mountains. Choose the one with the best quality, and its ore color is black and shiny, and it is hard and heavy. Dig it out, remove its soil and stone, and take pure ore.
Then, smelt it with a furnace. The stove is strong and thick, and it is built with fire-resistant materials. When the ore is placed, the fuel charcoal is burned under it, and the fire is hot, and it will be fierce and even. The fuel charcoal is dry and the flame is high, which can help the firepower. When the ore is melted, it flows into molten iron, and the impurities float up, and it is cleaned.
When the molten iron is slightly cold, it condenses into a block of iron. After that, it is hit with a hammer, and the sledgehammer falls, and there is a sonorous sound. The impact makes it broken, and the size of the pieces varies. Then grind it with a grinding stone, which is delicate and firm, and grinds back and forth, and the iron becomes a powder. The thickness is adjusted according to the use. It can be coarse to drain, or fine to be used as medicine, depending on the needs.
There is also a method of water quenching. After the molten iron forms a block, it is quickly thrown into the water, and the water excites the iron to crack, and it is easy to grind. And after water quenching, the iron properties are slightly changed, whether it is hard or tough, and the properties of the end are also affected.
The system of iron powder is related to the heat, strength, and material. Only with the attention of the craftsman can the best be obtained for various purposes.
