1. Material Q195(Black Wire Low Carbon Steel Wire For Nail Making)
Hard nails wire was made by Q195 wire rod .Wanlida buy this material from SHANXI ZHONGYANG IRON AND STEEL CO., LTD, which is the biggest steel factory in China. Q195 wire rod element composition is as follows :
C≤0.07; S≤0.023; Si≤0.09; Mn≤0.32; P≤0.025
Because This type of wire rod has less impurities, so Q195 is very fit for drawing.The diameter is 6.5mm. Generally, Daily output of Wanlida is 120 tons.
2. Drawing(Black Wire Low Carbon Steel Wire For Nail Making)
There are two kinds of drawing machine : powder drawing and water drawing . powder drawing is fit for junior drawing ( 6.5mm ~ 4.0mm ).
One powder drawing machine has 4 tanks and 4 molds. One tank is matched with a mold. Each of them are offered energy by a electromotor. 0.9mm(max)can be "eat" when the wire cross a mold. There are no loss of weight during drawing.
