摘要：随着冷轧设备及工艺水平的不断改进，自动化水平的不断提高，硅钢的板型、磁性、尺寸等因素以控制的较好，而国防工业、机械电子等众多产业对硅钢产品表面质量要求也不断提高，硅钢的表面质量变得越来越重要，目前硅钢表面质量控制水平的高低已成为高端客户选择的重要参考标准之一。现阶段，以宝钢1550机组为例，油烧缺陷已成为该产线主要的表面缺陷之一，直接影响产品质量及成材率。目前，对油烧缺陷的机理研究较少，而温度和油烧缺陷具有直接的关系。本论文通过对冷轧硅钢过程的分析，建立了冷轧硅钢过程的温度模型，并利用C#编写了冷轧硅钢的温度预测软件。通过软件，分别研究了轧制规程、乳化液温度、乳化液流量等参数对出口硅钢温度的影响规律，并最终提出了避免油烧缺陷的措施。21793

Cold Rolled Silicon Steel Temperature and the Influence on Oil Burn Defect
Abstact:With the continuous improvement of cold rolling equipment and technology level, to continuous improvement of automation, shape, size and other factors, the magnetic steel to control better, and national defense industry, machinery and electronics and many other industries on the silicon steel product surface quality requirements are also rising, the surface quality of silicon steel becomes more and more important, the current level of silicon steel surface quality control level has become one of the important reference standard high-end customer choice. At present, the No. 1550 unit as an example, oil burning defect has become one of the surface defects of the production line mainly, directly affect the product quality and yield. At present, the study on the mechanism of oil burning defect is less, and the temperature and oil burning defect has direct relationship. In this paper, through the analysis of the cold rolled silicon steel process, a temperature model of cold rolled silicon steel process, and use C# to prepare a cold-rolled silicon steel temperature prediction software. Through the software, the influence of parameters of rolling temperature, emulsion, emulsion flow rate on the export of steel temperature were studied, and finally put forward to avoid oil burning defect measure.
Keywords: cold rolling; roll temperature field; simulation; oil burning defect
