Hot drawing is drawing after heating or drawing while heating, the purpose is to enhance the flexibility and stretchability of the wire under high-temperature conditions. In layman's terms, it is to make materials or sizes that are not easy to stretch easier to stretch.
Cold drawing is a common metal wire processing method on the market today. Without heating, the wire is forced to be stretched and cold-formed by using drawing fluid as a lubricating and protective liquid, which will change the crystal structure.
Practical comparison of hot-drawn steel wire and cold-drawn steel wire:
Rela: Rela is currently only in the conceptual stage, including no such equipment abroad. However, very few special wires do need heat drawing, but the current market demand is too low, only some laboratories need this kind of machine. Therefore, no manufacturer is willing to invest in the implementation and research of this equipment. According to my judgment and some existing technologies, it is not difficult to realize this technology. It seems that it depends on the size of the driving force of the market.
Cold drawing: The most commonly used wire cold forming and cold working technology. The technology is mature and widely used in various industries: wire and cable, steel wire rope, molybdenum wire cutting wire, cleaning ball, and so on.
