【摘要】：步進式加熱爐是一種通過步進梁(或步進爐底)的上升、前進、下降、后退的循環(huán)動作來實現(xiàn)對坯料步進輸送的連續(xù)加熱爐,主要應用于鋼坯軋制前對其進行爐內步進輸送并加熱。它是鋼材軋制過程中必不可少的重要熱處理設備,已被廣泛地應用于現(xiàn)代鋼鐵工業(yè)。本文以某企業(yè)步進式加熱爐爐底機械的液壓系統(tǒng)為研究對象,首先在確定步進式加熱爐的主要技術參數和爐底機械結構的基礎上,計算了液壓系統(tǒng)的工況,對液壓泵站、平移液壓回路及升降液壓回路進行了設計和分析;其次,對步進爐爐底機械液壓系統(tǒng)的平移液壓缸進行了設計,利用有限元分析軟件ANSYS對液壓缸缸體進行了靜力學分析,根據分析結果對缸體進行輕量化改進;然后,對采用定量泵系統(tǒng)、恒壓系統(tǒng)和負載敏感系統(tǒng)的步進爐液壓系統(tǒng)的驅動功率、有效功率和能量利用率進行了分析,比較了三種液壓系統(tǒng)的節(jié)能效果,論證了負載敏感系統(tǒng)在節(jié)能降耗方面的優(yōu)越性;最后,對比例方向閥、負載敏感變量泵等關鍵液壓元件進行了靜態(tài)、動態(tài)分析,選擇AMESim軟件搭建了液壓元件的模型以及整個平移液壓回路的系統(tǒng)模型,并進行了仿真研究。本課題研究面向生產實際,對步進式加熱爐液壓系統(tǒng)的節(jié)能問題提出了解決方案,為以后步進爐爐機液壓系統(tǒng)的設計提供了新的依據,其市場前景和社會經濟效益十分良好。
[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.
