高硬度金属箔材道次工艺设计与累积变形有限元分析

近年来，随着信息、电子产业的兴旺发达，产品向小型轻量化发展，高硬度金属箔材的需求量越来越大，并且还将向汽车排气净化装置、精密钢片弹簧材、装修建材等方面延伸，市场可望大幅度扩大。

轧制金属箔材道次工艺设计是一个复杂而关键的过程，需要考虑多个因素，如材料类型、厚度、宽度、硬度、弹性模量等。在设计过程中，需要确定轧制机的辊缝间距、辊径、轧制力、轧制速度、冷却方式等参数，并进行相应的调整和优化，以达到所需的产品形状、尺寸和性能要求。

累积变形有限元分析是一种基于计算机模拟的数值方法，可以模拟金属箔材在轧制过程中的应力、应变和变形等物理量变化情况。通过分析和比较不同道次工艺设计的结果，确定最优的工艺方案。同时，结合实验验证，可以进一步提高模拟的准确性和可靠性。

因此，对于金属箔材生产企业来说，准确的道次工艺设计和累积变形有限元分析具有重要的意义，可以帮助企业优化生产流程、降低成本、提高产品质量和市场竞争力。

In recent years, with the prosperity and development of information and electronic industries, the demand for high-hardness metal foils has been increasing as products are becoming smaller and lighter. This demand is expected to expand significantly in markets such as automotive exhaust purification devices, precision steel spring materials, and decoration and construction materials.

The process design of rolling metal foil is a complex and critical process that involves considering multiple factors such as material type, thickness, width, hardness, and elastic modulus. In the design process, it is necessary to determine the roll gap distance, roll diameter, rolling force, rolling speed, cooling method, and other parameters of the rolling machine and make corresponding adjustments and optimizations to achieve the desired product shape, size, and performance requirements.

Accumulative deformation finite element analysis is a numerical method based on computer simulation that can simulate the changes in physical quantities such as stress, strain, and deformation of metal foils during rolling. By analyzing and comparing the results of different process designs, the optimal process scheme can be determined. Furthermore, combined with experimental verification, the accuracy and reliability of the simulation can be further improved.

Therefore, accurate process design and accumulative deformation finite element analysis are of great significance for metal foil production enterprises, as they can help optimize production processes, reduce costs, and improve product quality and market competitiveness.
