摘    要：热轧带钢力学性能预报技术兴起于20世纪70年代,因其具有广阔的应用前景,从而受到了国内外众多学术机构和企业的重视,然而,该技术的实际应用、特别是在线应用效果一直不理想。作者认为,造成这种现象的首要原因,是生产线的数据质量较差,从而使预报的可靠性大为降低。针对该问题,提出了力学性能预报技术实用化的解决思路,即把冶金机理和统计建模相结合,建立热轧带钢力学性能预报的分布式模型。实践证明,这一思路是可行的。

Abstract: Mechanical property prediction of hot rolled strip rose in the 1970s.Because of its broad application prospect,academic institutions and enterprise paid much attention to the technology.However,its industrial application,especially on-line application is not satisfactory.This paper points out that the fundamental reason is low-quality data which reduces the prediction reliability significantly.To this difficult problem,a practical solution to the property prediction of hot rolled strip is proposed.Practice proves the solution to be effective.
