在离心转速和浇注温度恒定的条件下，考察了０Ｔ至０１８Ｔ不同强度稳恒电磁场对离心铸造０Ｃｒ１７Ｍｎ１４Ｍｏ２Ｎ不锈钢铸态组织和室温加工性能的影响。试验结果表明，铸态组织中的残余铁素体随磁场强度的提高而由不均匀的长条状变为粗化的块状组织，且分布均匀，促使铸坯塑性提高。磁场强度达到临界值００８Ｔ之后，残余铁素体随着磁场强度提高而细化，分布弥散，使铸坯塑性下降。分析表明，造成这种性况的原因是电磁场同时起到两方面的作用，一方面促使铁素体形成元素向核心偏聚，增加铁素体的稳定性，粗化残余铁素体；另一方面增加晶核数量。
Centrifugal speed and pouring temperature constant under the conditions of 0T to 0 18T different concentrations of steady electromagnetic field on the centrifugal casting 0Cr17Mn14Mo2N stainless steel castings and room temperature processing performance. The experimental results show that the residual ferrite in the as-cast microstructure changes from non-uniform strip to coarser massive structure with the increase of magnetic field strength, and the distribution is uniform, which promotes the plasticity of cast slab. After the magnetic field strength reaches the critical value of 008T, the residual ferrite refinement with the increase of magnetic field strength, distributed dispersion, the slab plasticity decreased. The analysis shows that the reason of this kind of situation is that electromagnetic field plays two roles at the same time. On the one hand, it promotes the segregation of ferrite forming elements to the core, increases the stability of ferrite and coarsens the residual ferrite; Increase the number of nuclei.
