| Abstract: | The high frequency pull casting of phosphor bronze was studied in the paper. This process is characterized by short pitch, high frequency and the second thrust reversers. The results show that high frequency pull casting can refine grains, diminish ingredient segregation and dendritic segregation, which helps to obtain a fine homogeneous ingot, reduce the defect rate in subsequent processing as well as greatly improve production efficiency. |
