SWRH77B盘条时效试验研究

Study on Ageing Experiments of SWRH77B Hot-rolling Wire Rods

分析证明了温度和时间对SWRH77B盘条性能的影响。选择一组人工时效的试验条件，进行人工与自然时效方法的对比试验，通过试验验证了可以通过选定条件下的人工时效试验来代替自然时效试验。

Temperature and time influencing on properties of SWRH77B have been proved. Comparing artificial ageing with natural ageing by experiments, the result showed that artificial ageing test can replace natural ageing test.
