采用压力润滑技术进行钢丝拉拔的应用研究

针对传统拉拔润滑方法易堵塞炉管,钢丝扭转值不达标、扭转断口分层,模具和钢丝表面黏结等问题,采用涂敷器和压力模润滑技术进行改进,并进行理论分析和实际验证。结果表明,采用压力润滑技术进行拉拔,钢丝表面的润滑膜层面质量比用传统的拉拔方法增加50%~80%;低速拉拔时,压力模和涂敷器组合应用比只用压力模效果要好;钢丝的力学性能有所改善,在强度增加的同时,扭转值也增加,且断口有很大程度的改善。

Application research of steel wire drawing technology by pressure lubrication

In order to improve traditional lubrication drawing methods easy to plug furnace tube, the torsion value non- compliance, torsion fracture stratification, wire surface and drawing mold bonding, the applicator and pressure die lubrica- tion technology are adopted. The results show that lubricating film surface mass increase 50% to 80% with the drawing pressure lubrication technology comparing with traditional wire drawing method. Drawing at low speed, pressure mold draw- ing combination with coating applicators than just with a pressure mold better results, mechanical properties of steel wire improved. Not only the increase in tensile strength, but also to increase in the torsion value of the wire, and the fracture al- so improved a great deal.
