Why are the wire drawn in rolls? , Because when we use cold drawn wire, because of the different bundled items, the requirements for its length are also different. When we use cold drawn wire, we can cut it according to actual length requirements to avoid waste. The straightening steel bars on the market have high carbon content, high rigidity and are not easy to bend, so the length specification is relatively fixed. But when we use it, if the length exceeds, the volume must be reduced accordingly, which is likely to cause waste; if the length is not enough, welding is required, which increases the workload. The cold drawing of the coil effectively avoids waste and improves the utilization rate of the cold drawing. The cold drawn wire is made of metal cold processed products. The raw material is the steel bars we often see. Especially when the advantage is on the street, the truck will carry this steel bar and polish it on the ground, which is particularly harsh.
The cold-drawn wire processing technology makes the diameter hole of the round steel smaller and smaller, and the diameter of the bar becomes longer and longer. Repeating this process can improve the plasticity of the hardness. Products are widely used in the building materials industry, and the inspection standards for cold drawn wires will be improved accordingly.
