摘　　要：通过对步进梁式加热炉的运动特点分析,对其设计了一种节能液压系统,本液压系统主要采用液压泵控调压、比例阀节流调速、蓄能器能量回收再利用相结合的方式进行控制,在升降液压缸下降时回收钢坯和步进梁的重力势能,在步进梁上升时,利用储存在蓄能器组中的压力油液驱动升降液压缸上升,同时通过控制器主动调整泵站供油压力,使系统压力与负载相匹配。利用AMESim软件对节能液压系统进行仿真研究,并且与常规液压系统进行仿真对比,研究结果表明设计的节能液压系统满足工况要求,能够降低泵站配置能力,最大限度的节约能量。Based on analysis the motion characteristics of Walking Beam Furnace,design its energy saving hydraulic system.The system is controlled by the combination of hydraulic pump-controlled pressure regulation and proportional valve,and energy recovery and reuse of accumulator.The gravitational potential energy is recovered when the hydraulic cylinder is lowered,and the pressure oil stored in the accumulator is used to drive the rising of walking beam when the cylinder rises.At the same time,the pump station oil supply pressure is adjusted actively to match the system load pressure.The energy-saving hydraulic system is simulated by AMESim software,and compared with the conventional hydraulic system.The results show that the energy-saving hydraulic system meets the requirements of working conditions,reduces the allocation capacity of pump station and maximizes energy saving.
