【正文】 河北聯(lián)合大學(xué)輕工學(xué)院 QINGGONG COLLEGE, HEBEI UNITED UNIVERSITY 畢業(yè)設(shè)計(jì)說明書 設(shè)計(jì)(論文)題目: 高爐防灌渣撥風(fēng)控制系統(tǒng) 學(xué)生姓名: 學(xué) 號(hào) : 專業(yè)班級(jí) : 學(xué) 部: 指導(dǎo)教師: 2020 年 05 月 20 日 摘 要 I 摘 要 隨著國家工業(yè)的發(fā)展,在冶金企業(yè)中煉鐵技術(shù)的提高,高爐容積的不斷大型化,對(duì)高爐的穩(wěn)定性的要求越來越高,而作為高爐煉鐵系統(tǒng)中的鼓風(fēng)系統(tǒng)是高爐煉鐵當(dāng)中重要的輔助工藝之一,鼓風(fēng)系統(tǒng)中的撥風(fēng)系統(tǒng)的自動(dòng)化設(shè)置又是關(guān)系到整個(gè)鼓風(fēng)系統(tǒng)穩(wěn)定的關(guān)鍵因素, 在高爐冶煉過程中如果一旦出現(xiàn)高爐鼓風(fēng)機(jī)故障停機(jī),供風(fēng)中斷等情況,就極易會(huì)造成高爐“坐料”、“風(fēng)口灌渣”等惡性事故,嚴(yán)重影響高爐生產(chǎn),不僅會(huì)造成設(shè)備的損失,也會(huì)對(duì)高爐的使用壽命、 高爐的穩(wěn)定性產(chǎn)生很大影響,阻礙整個(gè)企業(yè)的生產(chǎn)經(jīng)營,直接和間接損失巨大 ,因此, 自動(dòng)撥風(fēng)控制系統(tǒng)的 開發(fā) 對(duì)于整個(gè)高爐安全穩(wěn)定生產(chǎn)和企業(yè)高效率的運(yùn)轉(zhuǎn)具有重大安全保障和經(jīng)濟(jì)效益。 本論文所設(shè)計(jì)高爐防灌渣自動(dòng)控制系統(tǒng)的設(shè)置的目的是當(dāng)一臺(tái)風(fēng)機(jī)出現(xiàn)故障斷風(fēng),影響高爐生產(chǎn)時(shí),自動(dòng)控制系統(tǒng)及時(shí)動(dòng)作,利用撥風(fēng)系統(tǒng)判斷出符合撥風(fēng)要求的風(fēng)機(jī),通過控制撥風(fēng)閥的開啟,將滿足條件的正在向其它高爐供風(fēng)的風(fēng)機(jī)的風(fēng)量調(diào)撥一部分分給故障停風(fēng)的高爐,以保證出現(xiàn)故障的風(fēng)機(jī)所供應(yīng)的高爐不至于灌渣從而維持高爐正常生產(chǎn),同時(shí)不影響提供撥風(fēng)的機(jī)組的正常工作。 本文首先介紹了組態(tài)軟件的發(fā)展和組態(tài)軟件的基本組 成、特點(diǎn)及組態(tài)軟件體系結(jié)構(gòu)進(jìn)行了較全面的闡述 ,通過分析 ,肯定了組態(tài)軟件作為生產(chǎn)過程控制系統(tǒng)編程工具的意義 .其次介紹本文西門子 WinCC 組態(tài)軟件應(yīng)用的系統(tǒng) – 撥風(fēng)控制系統(tǒng)的原理、系統(tǒng)設(shè)計(jì)、閥門的選擇和撥風(fēng)量的控制機(jī)算 .此外 ,本文從撥風(fēng)控制系統(tǒng)出發(fā) ,應(yīng)用西門子組態(tài)軟件來設(shè)計(jì)并制作撥風(fēng)控制畫面 .最后 ,將所設(shè)計(jì)的撥風(fēng)控制系統(tǒng)及監(jiān)控畫面投入實(shí)際生產(chǎn)來檢驗(yàn)其是否符合生產(chǎn)需求 ,并作出總結(jié) . 關(guān)鍵詞 :高爐;組態(tài);可編程控制器;撥風(fēng)控制 Abstract II Abstract Along with the development of national industries, in metallurgical enterprise in the improvement of the ironmaking technology, the stability of the blast furnace of demand is higher and higher, and as a blast furnace ironmaking system of airing system of blast furnace ironmaking is one of the important auxiliary process, the automation of airing system relates to the stability of the system, wind supply interruption, extremely easy will cause the blast furnace malignant accident, the serious influence blast furnace production, it will cause the blast furnace damaged, and have a great effect on the stability of the blast furnace, influence the whole the production and operation of enterprises. The automatic dial the air control system development for the safety and stability of blast furnace production and enterprise high efficiency of the operation has the great security and economic benefits. The purpose of the setting of the switch control system designed in this paper is a timely action when a wind turbine failure off the wind, influence the blast furnace production, use of airing system to determine the requirements of the the fan. By control dial wind valve opening, to ensure that the fault blast furnace can maintain the normal production . The safety and stability of blast furnace production and enterprise high efficiency of the operation system has the great security and economic benefit Firstly, the development of configuration software, the fundamental constitution for configuration software and characteristics are analyzes, and the configuration software system construction is also introduced. This paper considers that building a process control system with configuration software is important. Secondly, the system using Wincc control software ,which principle ,design ,choice of valve and the control calculation of volume of the wind. furthermore, on the basis of air intake system, I employ the Wincc Control software to design and make the drawing of air intake system. Finally, put the system and drawing that have been designed into use in factory to test their performance. Then summarize the result. Keywords the blast furnace。 onfiguration。 Programmable Logic Controller。 air intake control system 目 錄 III 目 錄 摘 要 ...............................................................................................................................
