摘要
基于可持续发展、轻量化、长生命周期的制造业发展背景,对各行业的用钢提出了高品质要求。为了减轻合金元素的氧化反应对双相钢的负面影响,研究设计了一种Al元素代替Si元素的新型双相钢,研究其连续退火工艺及性能影响规律。实验结果表明:随着退火温度的升高,抗拉强度与强塑积先升高后减小,延伸率、屈服强度升高;随着缓冷温度的升高,钢材的抗拉强度、屈服强度升高而延伸率与强塑积降低。由此可见,优化连续退火工艺参数可以综合提升双相钢的性能,提高其在不同领域的应用潜力。该研究为连续退火工艺的进一步改进提供了理论基础和实验依据。
The development background of sustainable development,lightweight,and long lifecycle manufacturing industry has put forward high-quality requirements for steel use in various industries.In order to reduce the negative impact of oxidation reaction of alloy elements on dual phase steel,a new type of dual phase steel with Al element replacing Si element was studied and designed,and its continuous annealing process and performance influence law were studied.The experimental results show that as the annealing temperature increases,the tensile strength and strength plastic product first increase and then decrease,while the elongation and yield strength increase.As the slow cooling temperature increases,the tensile and yield strength of the steel increases,while the elongation and strength plastic product decrease.It can be seen that optimizing the continuous annealing process parameters can comprehensively improve the performance of dual phase steel and enhance its application potential in different fields.This study provides a theoretical basis and experimental basis for further improvement of continuous annealing technology.
