Reducing the Central Porosity of Billet by Mathematical Simulation and Small Quantity Test
Through the simulation calculation of railway wheel steel CL60,it is found that the superheat and secondary cooling system have little effect on the solidification end position,and the pulling speed has the greatest effect on the solidification end position.By adopting the methods of low and constant pulling speed,weak secondary cooling strength and appropriate electromagnetic stirring strength,the problems of central porosity and carbon segregation of billet are better solved.
