摘　　要：5m宽厚板放尺参数为人工根据经验编制,放尺影响参数采用区间模式分段判断,现场使用和维护人员难以掌握其内在的编写规律,需要依据现场情况不断更新数据。同时缺少各因素对于放尺长度影响的全面.数据分析,放尺数据精度差。基于以上几点原因,宽厚板厂通过对头尾放尺机理的研究;放尺参数与放尺量多元非线性模型建立;采用三维线性头尾放尺模型,减少了头尾放尺量的坯料设计,提高宽厚板厂成材率,有效的.降低了宽厚板厂生产成本。The sizing parameters of 5m wide and heavy plate of NISCO are set up manually according to experience.The factors affecting the sizing parameters are confirmed by steps with interval mode,it is difficult for operators and main-tainers to master the internal rules,because the data require continuous update according to the site situation.At the same time,there is a lack of comprehensive data analysis of the respective influences of various factors on the length of the sizing,and the accuracy of the sizing data is poor.Based on the above-mentioned reasons,through the research on the mechanism of head-end sizing,the establishment of multiple nonlinear models for sizing parameters and sizing quan-tity,and the adoption of 3D linear head-end sizing model instead of the previous key sizing factors,the slab design of head and tail sizing is reduced,the yield is increased,and the production cost of Wide and Heavy Plate Mill is effec-tively reduced.
