0. 023Ca ) for electro-hydraulic controller has been first melted at Daye Special Steel Co Ltd by 20 t electronic arc furnace and refined in ladle furnace and vacuum degassing unit
cast 1. 2 t ingot and forged into products. The transverse mechanical properties and machinability have been enhanced significantly by feeding bismuth cored wire(Bi:0. 036% ) and adding rare earth nodulizer (Ce: 0.054% ). Comparing with that of the free Bi-Ce steel
the total number of inclusion of the containing Bi-Ce steel decreases by 84. 4% and the number of MnS inclusion decreases by 85. 5%
average size of inclusion increases from 4. 5 μm to 13. 7 μm and cut force lower by 70~80 N with thicker and more easily broken chips
the transverse reduction of area increases from 3% to 17% .
