| Abstract: | Sulfur-based free-cutting steel uses the brittleness of sulfide to improve the cutting performance of steel.The shape,size and distribution of sulfide are the key factors that determine the cutting performance of free-cutting steel.Shanghai University cooperated with Wuhu Xinxing Ductile Iron Pipe Co.,Ltd.to improve the shape and distribution of sulfides by adding Te to the 1215 MS free-cutting steel,and enhance the cutting performance of the product.The results showed that after adding Te with mass fraction of 0.016%to sulfur-based free-cutting steel,the three-dimensional morphology of sulfide in free-cutting changed from strip to ellipsoid,and the sulfide form reached grade 1-2 of German standard SEP1572 of high sulfur free cutting steel.The average area of sulfide reached 124μm2,which was more than four times the sulfide area of general free-cutting steel sulfide.Compared with AISI12L14 and SUM24L lead-based free-cutting steel for more than120 hours of cutting processing,the tool wear surface finish had reached the same effect.Te-based free-cutting steel successfully replaced lead-based free-cutting steel. |
