【摘要】：隨著社會工業(yè)的快速發(fā)展，在現(xiàn)代冶金行業(yè)里，伴隨高精度液壓AGC控制系統(tǒng)在軋鋼生產(chǎn)線上越來越廣泛地使用，，液壓AGC控制技術(shù)的應(yīng)用也就越來越引起大家的關(guān)注。液壓厚度控制系統(tǒng)(AGC)是現(xiàn)代大型板帶軋機(jī)的核心系統(tǒng)，而軋機(jī)伺服液壓缸是AGC系統(tǒng)中的直接執(zhí)行元件，工作在AGC系統(tǒng)的閉環(huán)回路中，是回路中的一個關(guān)鍵環(huán)節(jié)，其性能指標(biāo)直接影響系統(tǒng)的精度和動、靜態(tài)品質(zhì)，因此從軋機(jī)AGC液壓缸本身的研究出發(fā)，對于優(yōu)化伺服液壓缸的設(shè)計，提高液壓缸本身和系統(tǒng)的可靠性有著很大的幫助。 本文結(jié)合國內(nèi)外軋機(jī)伺服液壓缸的生產(chǎn)和發(fā)展?fàn)顩r，對軋機(jī)AGC液壓缸自身的結(jié)構(gòu)、性能和可靠性三部分內(nèi)容進(jìn)行研究。 首先，介紹了軋機(jī)AGC液壓缸的結(jié)構(gòu)和原理，細(xì)述了其主要的零部件如活塞和缸體的加工工藝；并對軋機(jī)AGC液壓缸進(jìn)行了靜態(tài)和動態(tài)特性的測試。其次，從國內(nèi)液壓缸的實(shí)際生產(chǎn)情況出發(fā)，對軋機(jī)AGC液壓缸的維修記錄進(jìn)行統(tǒng)計并對其可靠性進(jìn)行了調(diào)查，獲得了真實(shí)可靠的數(shù)據(jù)；在此基礎(chǔ)上，運(yùn)用有限元分析方法，借助ANSYS軟件對軋機(jī)AGC液壓缸上使用最為廣泛的格萊圈密封在其無油壓和正常工作壓力下進(jìn)行了變形和力學(xué)情況的分析，有助于了解密封圈在液壓缸上的磨損和失效情況。最后，結(jié)合實(shí)際情況，從軋機(jī)AGC液壓缸主要零部件的機(jī)加工生產(chǎn)、產(chǎn)品的裝配工藝、AGC液壓缸的特殊處理和防銹除銹及去污處理等幾方面提出了合理的建議，以促進(jìn)在實(shí)際生產(chǎn)過程中延長軋機(jī)AGC液壓缸的有效使用壽命，提高其可靠性。
[Abstract]:With the rapid development of social industry, with the high precision hydraulic AGC control system more and more widely used in steel rolling production line, the application of hydraulic AGC control technology has attracted more and more attention in modern metallurgical industry. The hydraulic thickness control system (AGC) is the core system of the modern large plate strip mill, and the servo hydraulic cylinder of the mill is the direct executive element in the AGC system, which works in the closed loop of the AGC system and is a key link in the loop. The performance index directly affects the precision and the dynamic and static quality of the system. Therefore, the research on the AGC hydraulic cylinder of the rolling mill is of great help to optimize the design of the servo cylinder and improve the reliability of the hydraulic cylinder itself and the system. According to the production and development of servo hydraulic cylinder of rolling mill at home and abroad, the structure, performance and reliability of AGC hydraulic cylinder of rolling mill are studied in this paper. Firstly, the structure and principle of AGC hydraulic cylinder of rolling mill are introduced, the processing technology of its main parts such as piston and cylinder block is described in detail, and the static and dynamic characteristics of AGC hydraulic cylinder of rolling mill are tested. Secondly, according to the actual production situation of domestic hydraulic cylinder, the maintenance record of AGC cylinder of rolling mill is statistically analyzed and its reliability is investigated, and the real and reliable data are obtained, on the basis of which, the finite element analysis method is used. With the help of ANSYS software, the deformation and mechanics of the most widely used Greer ring seal on the AGC hydraulic cylinder of rolling mill under no oil pressure and normal working pressure are analyzed, which is helpful to understand the wear and failure of the sealing ring on the hydraulic cylinder. Finally, according to the actual situation, some reasonable suggestions are put forward from the following aspects: machining and production of main parts of AGC hydraulic cylinder of rolling mill, special treatment of product assembly technology and anti-rust and rust removal and decontamination, etc. In order to prolong the effective service life and improve the reliability of AGC hydraulic cylinder in the actual production process.
