【 摘 要 】

Continuous casting EMS technology for 20CrMnTiH(FQ)gear steel bloom internal quality optimizing control was researched, based on the equipment of 360mmX450mm bloom casting machine conditions which is one factory of China. Ensure the install position of F-EMS which installed close at the end of liquid core by take numerical simulate calculation for the process of solidifying and heat transfer, measured the stirring magnetic field intensity(T), and carried out comparing experiment to find out the effects of stirring intensity on bloom internal quality, the optimal process parameters of combined EMS have been defined at last, taim to control 20CrMnTiH(FQ) gear steel bloom internal quality to be densify and homogenize have been realized.
