近年来,要求冷轧镀锡板产品减薄至0.10～0.15mm 厚度范围的订单越来越多;另一方面,为提高现有热带钢轧机的生产能力,又要求增大冷轧机入口板厚,为适应这种形势的变化发展,提出了“冷连轧机组最大压下率究竟能达多少”的重要问题。显然,欲得此结论,仅凭实践经验远不足以问题的分析与解决,而必须走建立正确数学模型的路。为此,在实验室基础上开发出一组轧制数学模型,并在四机架和五机架两种镀锡板冷连轧机上进行了仿真计算。结果表明,采用95～96%的累计压下率情况下,仍能保持稳定轧制条件,获得良好产品质量,且不突破设备强度极限。此外,在Hoogovens 实验室所研究出的这种模型还能显著提高镀锡板冷轧机的预设定精度。
In recent years, there is an increasing demand for cold-rolled tinplate products to be reduced to a thickness of 0.10-0.15mm. On the other hand, in order to increase the production capacity of existing hot-strip mills, Thick, in order to adapt to the change and development of this kind of situation, put forward the important question that “the maximum reduction rate of the tandem cold rolling mill can reach”. Obviously, for this conclusion, experience alone is far from enough to analyze and solve problems. Instead, we must follow the path of establishing a correct mathematical model. Therefore, a set of rolling mathematical model was developed on the basis of the laboratory, and the simulation calculation was carried out on two tandem cold tandem mills with four-stand and five-stand tin plates. The results show that under 95 ~ 96% of the total reduction rate, stable rolling conditions can be maintained, good product quality can be obtained without breaking the equipment strength limit. In addition, the model developed at Hoogovens Laboratories can significantly improve the preset accuracy of tinplate cold rolling mills.
