摘　　要：在型钢轧制领域,产品的规格尺寸控制是影响产品产量和质量的主要因素。由于型钢产品断面形状复杂,同时控制尺寸种类多,除了用先进设备保障之外,生产现场均设有规格尺寸调整岗位,但因为现场工况条件复杂,参数特征众多,同时有些特征无法直接测量或缺少测量装备,人工很难进行综合判断。这种经验控制的调整效率不高,需要根据数据关系进行模型化,而单纯地在大数据集上建模,模型的准确性不会太高。为了提高模型准确性,以钢轨规格控制为例,介绍了一种欠特征情况下的型钢规格控制建模及验证方法。In the field of section steel rolling,the size control of products is the main factor affecting the production and quality of products.Because the section shape of section steel products is complex and there are many types of control dimensions,in addition to the support of advanced equipment,there are size adjustment posts on the production site.However,due to the complex working conditions on the site,many parameter feature,and some feature cannot be measured directly or lack of measurement equipment.It is difficult to make comprehensive judgment manually.In order to improve the accuracy of the model,taking rail specification control as an example,this paper introduces a modeling and verification method of section steel size adjustment in the case of under feature.
