摘要
步进式加热炉是将钢坯加热到锻造温度的工业炉,因其具有加热均匀、表面磨损小的优点,在现代钢坯加热炉中得到广泛应用。就步进式加热炉的步进梁进行分析,主要研究步进梁的速度控制,从而减小钢坯在上升下降过程中的冲击。首先,分析了步进梁加热炉原液压系统原理,发现了原系统的缺陷和故障,从而提出了优化后的液压系统。其次,分析步进梁在托坯和放坯时的情况,进行了速度设计,考虑中间速度对步进梁与钢坯的碰撞情况的影响,较深入地研究了在托坯和放坯时速度为零的零冲击技术。最后,运用AMEsim软件进行速度和位移仿真,确定零冲击运动曲线的合理性。
Walking beam furnace is one of industrial furnace in which billet is heated to forging temperature ,it is widely used in modern billet furnace,becouse of its advantages of uniform heating and small surface wear. It having analyzed the walking beam of the furnace, the main research is about the speed control of walking beam , in order to reduce the impact of billet in the process of the ascending and descending.Firstly, having analyzed the original hydraulic system principle of the walking beam furnace, the defects and foults of the original system are found, then the optimized hydraulic system are put forwar~ Secondly, analysising walking beam in the process of hold billet up and down,speed is designed . Since the intermediate speed affects the collision of walking beam and the billet, the papper deeply studied the zero impact technology that the intermediate speed is zero in the process of hold billet up and down.Finally, using the AMEsim simulation software to simulate speed and displacement, the rationality of the motion curve of zero impact is determined.
