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."
