采用304奥氏体不锈钢盘条,研究了将圆截面盘条轧制成扁钢丝的过程中,不同压下量对轧后宽展的影响,分析了材料内部的组织和硬度变化,探讨了轧制中的应变分布。结果表明:本实验条件下,当压下率小于58.9%时,宽展明显并随压下率的变化呈线性关系,变形比较大时,宽展的变化减小;随着压下量的增加,轧后扁钢丝的组织及硬度的变化逐渐均匀,意味着变形逐渐趋于均匀。

Influence of different reduction on lateral spread after flat rolling of 304 austenite stainless steel rods at room temperature was investigated. Also, microstructure and microhardness were analyzed and distribution of strain during rolling was discussed. It shows that under this condition, when reduction rate Δh/h0 is less than 58.9%, the spread changes markedly, which is expressed by linear relation with reduction ratio increases, and the spread changes slowly when there is a severe deformation. Moreover, the changes of microstructure and microhardness become homogeneous with reduction increases, indicating deformation tends towards uniformity gradually.
