简介

 

  The company invests heavily in technology research and development, and strives to develop more advantageous products. It has made breakthroughs in production process for many times, and has increasingly become dominant in the market; at the same time, the company has recently won the certificate from Luoyang Enterprise R&D Center and is now in a leading position in the industry. In recent times, the company has made new breakthroughs in the wire drawing process. In the traditional process, the heat treatment of bright steel wire rods is generally performed in a vacuum furnace. When using a vacuum annealing furnace for heat treatment, the steel wire must leave the dedicated spooler, causing the subsequent roller die cannot achieve high-speed drawing. In order to solve this problem, we've modified the continuous annealing furnace used for the heat treatment of special steel wire rods, and used a high-purity inert gas to protect the wire surface during the heat treatment. Through repeated process tests, not only the heat treatment of bright wires has been achieved, but the problem of consistency during heat treatment has been solved. In the initial stage of the continuous heat treatment process test, serious hole shrinkage phenomenon occurred, and the maximum hole shrinkage even reached 0.5mm, causing the roller die drawing cannot be performed. Through the modification of tension spooler and unspooler, we have successfully controlled the hole shrinkage and ovality within 0.03mm, which guarantees the realization of high-speed and stable drawing, with the highest drawing speed reaching 300m/min, which is more than 10 times that of the traditional process.
