| 摘 要： | 针对低碳铝镇静钢连续热镀锌板抗时效性能较差的问题，通过镀锌板时效指数测量和内耗测量研究了卷取温度对抗时效性能的影响。试验结果表明，在620～710℃，随热轧卷取温度的提高，镀锌板固溶碳含量降低，抗时效性能提高，卷取温度从620℃提高到710℃，镀锌板时效指数降低19%。适当提高热轧卷取温度是改善低碳铝镇静钢热镀锌板抗时效性能的有效手段之一。

| Abstract: | To improve aging resistance of hot-dip galvanized low carbon aluminum killed steel sheet, the effect of coiling temperature on aging resistance was investigated by measuring aging index and internal friction of galvanized sheets. The results show that in the range of 620-710℃ higher coiling temperature leads to less solid solution carbon and better aging resistance of galvanized sheet. Aging index decreases 19 percent by increasing coiling temperature from 620 to 710℃. Properly increasing coiling temperature is one of the effective ways to improve aging resistance of hot-dip galvanized low carbon aluminum killed steel sheet. |
