摘要
捞钢机是连铸出坯系统的核心设备,其性能直接影响生产效率和安全性。针对传统齿轮齿条式捞钢机存在的提升架质量大、运行周期长等问题,提出一种四连杆式传动系统优化方案。通过机构简化、静力学与动力学建模,对比分析两种结构的驱动力矩、运行效率及适用场景。研究表明:四连杆式捞钢机提升架质量降低64.1%,运行周期缩短66.3%,显著优于齿轮齿条式结构。此外,结合工程案例验证了四连杆机构在小断面、高拉速铸机中的优势,为铸机选型提供了理论依据。
The steel lifting machine is a core equipment in the continuous casting billet extraction system,and its performance directly impacts production efficiency and safety.To address the issues of excessive weight of the lifting frame and prolonged operational cycles in traditional rack-and-pinion steel lifting machines,proposes an optimized four-bar linkage transmission system.Through mechanism simplification,static and dynamic modeling,a comparative analysis is conducted on the driving torque,operational efficiency,and applicable scenarios of the two structures.The results demonstrate that the four-bar linkage steel lifting machine achieves a 64.1%reduction in lifting frame weight,a 66.3%shortening of the operational cycle,significantly outperforming the rack-and-pinion structure.Furthermore,engineering cases validate the advantages of the four-bar linkage mechanism in small-section high-speed continuous casting machines,providing a theoretical basis for the selection of casting machines.
