| 摘 要： | 大冶特钢公司电液控制器用高端不锈钢1.4104 (/%:0.16C,1.23Mn,16.40Cr,0.41Ni,0.43Mo,0.023Ca)采用20 t电弧炉初炼、LF与VD精炼,铸1.2 t锭,径锻成材工艺生产,通过喂入Bi包芯线(Bi:0.036%)与稀土球化剂(Ce:0.054%)后该钢横向力学性能与切削性能大幅提高。与无Bi-Ce钢相比,含Bi-Ce钢夹杂物总量减少84.4%,MnS夹杂减少85.5%,夹杂物平均尺寸由4.5μm增至13.7μm,切削力平均降低70～80 N,切屑更厚,更加易断,横向断面收缩率由3%提高至17%。

| Abstract: | Quality stainless steel 1. 4104 ( /% ：0. 16C,1. 23Mn,16. 40Cr,0. 41Ni,0. 43Mo,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% . |
