摘　　要：泰山钢铁公司不锈钢板坯铸机的动态轻压下系统,其扇形段设备、控制系统和计算模型全部为自主设计、制造,首次实现了动态轻压下系统的完全国产化。实践表明该铸机设备性能稳定、控制模型计算准确,铸坯质量良好。对轻压下过程中,扇形段的受力变形进行了有效的补偿。通过大量的生产试验,对动态轻压下技术的关键控制参数进行了优化,得出了最佳的轻压下参数。The Dynamic soft reduction system of stainless steel slab continuous casting machine in Taishan Steel including the segments, control system and calculation module are all domestic designed and manufactured and thus the aim of whole dynamic soft reduction system made in China is realized for the first time. Practice shows that the casting machine is featured of high stability, calculation of the module is accurate and the quality of the slab is excellent. In the process of soft reduction the deformation of the segments is effectively compensated. The critical control parameters for the dynamic soft reduction technology are optimized through a series of production experiments and the optimal parameters for soft reduction determined.
