RESEARCH OF HELICAL MAGNETIC FIELD STIRRER IN BLOOM CONTINUOUS CASTING
A helical magnetic field stirrer that can generate both rotating and traveling forces is designed in this paper.The electromagnetic field and the flow field generated by the new equipment are simulated and compared with those generated by the traditional one.It can be seen that with the helical stirrer,the mass and heat transfer can be enhanced in three dimensions,while the traditional one can drive the melt flow only in two dimensions.In simulation,with the helical stirrer,the temperature gradient is almost 18.5%lower than that with the traditional one.The applied feasibility of the helical stirrer in the continuous casting has been analyzed also.Compared with the traditional stirrer,the helical one has the similar dimension and power consumption.it can be utilized instead of the traditional one in the mold,second cooling zone and ending stirring in continuous casting.
