Increasing bearing life by combining a novel manufacturing bearing steel process with multiscale modelling techniques

该项目旨在通过将新型轴承钢制造工艺与多尺度建模技术相结合来提高轴承寿命。新的制造工艺是在轴承钢连铸工艺中间包加装感应加热器的基础上提出的；这将显著增强夹杂物控制并延长轴承寿命。这项工作将与轴承疲劳相关的多标量效应建模相结合，从而优化疲劳微观结构，并为合金加工选择最佳加工参数。最终的结果将是计算机程序，以帮助制造商控制轴承钢加工，最佳钢加工规则，超净钢中夹杂物含量的量化方法，以及了解微观结构和成分的变化如何导致不同的轴承寿命。”

This project aims at increasing bearing life by combining a novel manufacturing bearing steel process with multiscalemodelling techniques. The new manufacturing process is based on adding an induction heater to the tundish of acontinuous cast process for bearing steel manufacturing; this will significantly enhance inclusion control and increasebearing life. The work will be combined with modelling of multiscalar effects associated to bearing fatigue, allowing tooptimise the microstructure for fatigue, and to select optimal processing parameters for alloy processing. The end result willbe computer programmes to aid manufacturers to control bearing steel processing, rules for optimal steel processing,methods to quantify inclusion content in ultra-clean steels, and understanding of how variations in microstructure andcomposition lead to different bearing life."
