摘要： 带钢传统的表面质量评价方法仅仅考虑了表面缺陷的数量及等级,而未考虑与客户应用密切相关的缺陷分布对表面质量的影响.在客户应用及带钢表面缺陷分布数据已知的情况下,建立线性规划模型,得出缺陷分布数据已知的带钢利用率,并将其与表面无缺陷的带钢利用率的比值作为衡量带钢表面质量的标准,由此得到一个基于客户应用的带钢表面质量评价方法,改变了传统的质量评价方法客户应用无法体现的局限性,保证了带钢表面质量评价的科学性及实用性.实例表明该方法可行、有效,且具有一定的推广性.

Abstract: The surface quality of strip steel is a very important aspect of strip steel quality. The traditional method of surface quality evaluation only considers the number and the level of defects, with regardless of the defect distribution which is closely related with the client application. This paper presents a linear programming model under the conditions of client application and the defect distribution data, then the strip utilization with and without surface defects are obtained, and their ratio can be used as a standard in testing the strip surface quality. This method avoids the limitations of the traditional quality evaluation which can't reflect the client application, ensuring the scientificity and practicality of the surface quality evaluation. The example indicates that the proposed method is feasible, effective and has a certain application.
