槽帮材料及其制造工艺研究进展

Research Progress on the Material and Manufacturing Process for Slot

通过分析槽帮构件的服役工况、失效形式提出槽帮材料的性能要求,并根据槽帮材料的发展趋势以及钢的合金化原则、理论和规律,以提高槽帮钢寿命为目标导向,权衡性能、寿命和成本,提出了以低碳、主加Mn、Si、微量添加保证淬透性和耐磨性元素,并通过复合强化技术手段,实现细晶化、纯净化和均匀化的槽帮新材料途径。实现材料强韧化,效益最大化。

In this paper, by analyzing the service condition and failure forms of slot,the performance requirements of slot were put forward. According to the development trend of the slot material as well as the steel alloying principle, theory and law, in order to improve the slot life, balancing the performance, life and cost, the new slot material should be low carbon, adding Mn, Si and other trace elements guaranteing hardenability and abrasion resistance. And through composite reinforcement technology, the slot realizes the grain fining, purification and uniformity.
