Applications of EMS and its development in Baosteel
EPM-related technologies are widely used in Baosteel,where a full-time working team is making their effort in various topics for better qualities of steel products.In this paper,applications and new developments of EMS technology in Baosteel are mainly introduced.Although EMS has already become conventional means for improving steel billet/bloom and slab qualities,there still exist problems due to low efficiency or unsatisfactory application results.To solve these problems,not only the internal mechanical structure of the EMS equipments,but also the relationship between EMS and solidification process,physical properties as well as fluid mechanics should be carefully investigated.By using of computer simulation,laboratory and on-line experiments,our understandings of EMS technology have been upgraded based on the obtained results.For improvement of equiaxed crystal ratio,the magnitude of EMS force plays a much more important role than superheat.And the nonlinear relations between power source frequence and EMS force are quite different for different types of EMS equipments,which means adjustment of frequence to a proper value is very important.
