| description | The influence of low-frequency electromagnetic-field on macrostructure of austenite stainless steel in horizontal continuous casting was investigated based on industrial experiment. The results show that application of appropriate electromagnetic stirring parameters can improve the macrostructure of austenitic stainless steel, in which both columnar grains and equiaxed grains are evidently refined and center porosity and shrinkage cavity can be remarkably decreased, and enlarging equiaxed grains zone. The industrial trials verify that the stirring intensity of austenite stainless steel should be higher comparing with plain carbon steel. Electromagnetic stirring has somewhat affected the macrostructure of the austenitic stainless steel even if the magnetic flux density of the electromagnetic stirring reaches average 90mT (amplitude reaches 141mT) in average at frequency f=3-4Hz. Due to a higher viscosity, rotating speed of molten stainless steel was 20%-30% lower than that of molten carbon steel in the same ma |
