摘要

如何提高铸坯表面质量来满足连铸生产要求,这是当前连铸技术发展的一项重要课题,而结晶器振动曲线的形状是影响铸坯质量的重要因素之一。现场的结晶器振动机构不可避免地存在间隙及摩擦,这些非线性因素对结晶器位移的影响是值得理论和实践探讨的。基于ADAMS仿真分析软件,创建结晶器驱动机构模型,虚拟仿真理想模型状态下结晶器振动的位移曲线,以及仿真模型在含有间隙和摩擦两因素时结晶器振动的位移曲线。研究结果表明,间隙是影响振动位移曲线的主要因素,而运动副摩擦、铸坯阻力在理想模型状态下对结晶器振动位移曲线的影响不大,但在含有间隙的机构中,会导致振动曲线的形状突变更加明显。

Abstract

How to improve the surface quality of slab to meet the requirements of continuous casting production is an important topic in the development of current continuous casting technology. And the shape of crystallizer displacement curve is one of the important factors that effects the casting machines and casting adobes. The scene?of?the?crystallizer?vibration can’t avoid clearance and friction These nonlinear factors which effect the crystallizer displacement are worthy of discussing in theory and in practice. Based on the simulation and analysis software ADAMS,creating the crystallizer drive mechanism,virtual simulation the crystallizer vibration displacement curve in ideal circumstances and involves the situation of clearance and fiction. The results show that the clearance is the main factor that effects the vibration displacement curve. However the friction of movement and resistance of slab hardly effect the vibration displacement curve in the ideal condition. But in the mechanism involving clearance,friction effects the shape of vibration curve in the different degree.
