摘　　要：本文用对比的方法确定了弯板及时效对电站用蜗壳钢板冷脆的影响。确认,弯板及时效会使蜗壳用钢板冷脆转变温度有明显的变化。In this article, the effect of cold bending deformation and ageing on cold short of the steel plate for spiral case of water turbine is determined by way of comparision. It is verified, that cold bending deformation and ageing notably increase cold short together with transfomation temperature.
