摘 要:鋼鐵工業(yè)是國家的基礎(chǔ)工業(yè)，新世紀(jì)以來，隨著中國經(jīng)濟(jì)的快速增長，中國鋼鐵工業(yè)繼續(xù)保持高速增長勢頭。特別是連鑄的發(fā)展促進(jìn)了鋼鐵生產(chǎn)流程的進(jìn)一步優(yōu)化，連鑄技術(shù)不斷推動著中國鋼鐵工業(yè)的快速發(fā)展。近幾年，由于我國連鑄技術(shù)與國外先進(jìn)水平還存在一定差距，所以連鑄機(jī)設(shè)備和技術(shù)大部分還是靠引進(jìn)。其中薄板坯連鑄機(jī)幾乎全部引進(jìn)，并有繼續(xù)引進(jìn)的趨勢；中薄板坯連鑄機(jī)、異型坯連鑄機(jī)全部引進(jìn)；大方坯連鑄機(jī)也有引進(jìn)的傾向。小方坯連鑄機(jī)經(jīng)過幾十年的發(fā)展，技術(shù)已經(jīng)很成熟，目前基本達(dá)到世界先進(jìn)水平。本次設(shè)計(jì)就是針對小方坯連鑄機(jī)振動裝置的設(shè)計(jì)。

　　　本文首先介紹了連鑄設(shè)備的發(fā)展和結(jié)晶器的概述及基本參數(shù)，然后介紹了設(shè)計(jì)方案和參數(shù)計(jì)算，最后介紹了安裝維護(hù)。本設(shè)計(jì)將正弦四連桿振動應(yīng)用于方坯連鑄機(jī)，優(yōu)化了結(jié)晶器振動的情況，提高了鋼坯質(zhì)量。

ABSTRACT:Iron and steel industry is the country's basic industries, the new century, with China's rapid economic growth, China's iron and steel industry continues to maintain high growth momentum. In particular, the development of continuous casting promote steel production processes to further optimize, continuous casting technology continues to promote the rapid development of China's steel industry. In recent years, there is still a gap between foreign countries and China in the continuous casting technology, so the equipment and technology of the domestic caster most still rely on foreign imports. Almost all of the thin slab casters rely on introduction, and it is becoming the trend; all medium thin slab caster and beam blank caster depend on foreign imports; bloom caster has a tendency to introduce from foreign imports. After decades of development, the technology of billet caster is already very mature, now it has basically reached the world advanced level. This design is for the billet caster vibration device. 

　　　This paper provides the information of the continuous casting equipment development and the overview and the basic parameters of crystallizer, and then introduces the design and parameter calculation of vibration device, and finally describes installation and maintenance. The design make the sinusoidal vibration applied to four-bar billet caster to optimize the mold oscillation situation and improve the quality of billet.
