摘 要:鋼鐵是國民經(jīng)濟(jì)的支柱，電爐煉鋼的原料是廢鋼，能源是電能。不僅是對資源的回收利用，同時也保護(hù)環(huán)境。電爐爐蓋升降和旋轉(zhuǎn)裝置能使電爐爐蓋既能與電爐爐體同時傾動，又能與爐體產(chǎn)生相對位移的使?fàn)t膛露出，實現(xiàn)裝料的要求。通常，電爐的爐蓋升降和旋轉(zhuǎn)均采用液壓驅(qū)動，可以使?fàn)t蓋在工作過程中能減少沖擊、震動以避免造成電極的折斷，以確保電弧爐正常冶煉操作的安全性和可靠性。因此，對電爐爐蓋裝置進(jìn)行合理設(shè)計具有十分重要的意義。 本文主要介紹為某鋼廠所設(shè)計的90t電爐爐蓋升降和旋轉(zhuǎn)裝置。主要內(nèi)容有：方案論證、液壓系統(tǒng)的設(shè)計計算，爐蓋支撐部分的設(shè)計，以及裝置的安裝、使用和維護(hù)等。 關(guān)鍵詞：90t電弧爐 爐蓋 升降和旋轉(zhuǎn)裝置 設(shè)計
ABSTRACT:Steel is the backbone of the national economy, it is the most commonly used in electric furnace steelmaking equipment. raw material of steelmaking is scrap, energy is an electric, not only is the recycling of resources, but also protect environment. Furnace cover lifting and rotary device can make the furnace cover capable of tilting and electric furnace body at the same time, but also can produce the furnace body and the relative displacement of the show, realize the charging requirements. Usually, electric furnace cover lifting and rotation is driven by hydraulic pressure, which can make the furnace cover in the work process can shake to avoid electrode broken impact and reduce the pressure, in order to ensure the safety and reliability of electric arc furnace smelting the normal operation. Therefore, it is very important for the rational design of furnace cover device has the significance. This paper mainly introduces the design of 90t furnace for a steel cover lifting and rotating device. The main contents are: the design and calculation of hydraulic system, the scheme argumentation, furnace cover support part design, as well as the installation, use and maintenance. Keywords: 90t electric arc furnace lid lifting and rotating device Design |
