介绍高强度轮胎钢帘线的特点及发展状况,详细分析铅浴淬火工艺对高碳钢及合金钢的影响,并对珠光体钢丝的拉拔机制进行探讨,指出珠光体的片层间距和位错与加工硬化密切相关,应变时效能改变钢丝的力学性能。为提高钢丝的强度,应开发高碳Cr合金或B合金线材。
The characteristics and development of high strength tire cord are introduced. The influence of lead bath quenching process on high carbon steel and alloy steel is analyzed in detail. The drawing mechanism of pearlite steel is discussed. The lamellar spacing and location of pearlite Wrong and work hardening is closely related to the strain aging can change the mechanical properties of steel wire. In order to improve the strength of the wire, should develop high-carbon Cr alloy or B alloy wire.
