【摘要】：步进式加热炉是一种通过步进梁(或步进炉底)的上升、前进、下降、后退的循环动作来实现对坯料步进输送的连续加热炉,主要应用于钢坯轧制前对其进行炉内步进输送并加热。它是钢材轧制过程中必不可少的重要热处理设备,已被广泛地应用于现代钢铁工业。本文以某企业步进式加热炉炉底机械的液压系统为研究对象,首先在确定步进式加热炉的主要技术参数和炉底机械结构的基础上,计算了液压系统的工况,对液压泵站、平移液压回路及升降液压回路进行了设计和分析;其次,对步进炉炉底机械液压系统的平移液压缸进行了设计,利用有限元分析软件ANSYS对液压缸缸体进行了静力学分析,根据分析结果对缸体进行轻量化改进;然后,对采用定量泵系统、恒压系统和负载敏感系统的步进炉液压系统的驱动功率、有效功率和能量利用率进行了分析,比较了三种液压系统的节能效果,论证了负载敏感系统在节能降耗方面的优越性;最后,对比例方向阀、负载敏感变量泵等关键液压元件进行了静态、动态分析,选择AMESim软件搭建了液压元件的模型以及整个平移液压回路的系统模型,并进行了仿真研究。本课题研究面向生产实际,对步进式加热炉液压系统的节能问题提出了解决方案,为以后步进炉炉机液压系统的设计提供了新的依据,其市场前景和社会经济效益十分良好。
[Abstract]:A walking furnace is a continuous heating furnace for the progressive conveying of billets through the movement of the rising, advancing, descending and retreating of the walking beam (or the bottom of the furnace). It is mainly used to carry out step-by-step conveying and heating of steel billet before rolling. It is an essential heat treatment equipment in the rolling process of steel, and has been widely used in modern iron and steel industry. In this paper, the hydraulic system of the bottom machine of a walking furnace in an enterprise is taken as the research object. Firstly, on the basis of determining the main technical parameters and the mechanical structure of the furnace bottom, the working conditions of the hydraulic system are calculated, and the hydraulic pump station is analyzed. The translation hydraulic circuit and the lifting hydraulic circuit are designed and analyzed. Secondly, the translational hydraulic cylinder of the mechanical hydraulic system under the furnace bottom is designed, and the static analysis of the cylinder body is carried out by using the finite element analysis software ANSYS. According to the results of the analysis, the lightweight improvement of cylinder block is carried out. Then, the driving power, effective power and energy utilization ratio of stepping furnace hydraulic system using quantitative pump system, constant pressure system and load sensitive system are analyzed. The energy saving effect of three hydraulic systems is compared, and the superiority of load sensitive system in energy saving and consumption reduction is demonstrated. Finally, static and dynamic analysis of key hydraulic components such as proportional directional valve and load sensitive variable pump are carried out. The software AMESim is selected to build the model of hydraulic components and the system model of the whole translational hydraulic circuit, and the simulation research is carried out. Based on the practical production, the paper puts forward a solution to the energy saving problem of the hydraulic system of the walking furnace, which provides a new basis for the design of the hydraulic system of the walking furnace in the future, and its market prospect and social economic benefit are very good.
