The utility model relates to an improved continuous casting ladle cover, which comprises a ladle cover body, a ladle cover hanging ring and a hanging chain device. The hanging chain device comprises a hanging ring, a hanging ring inlaying block, a plurality of hanging chains and a detachable light top block. The hanging ring of the ladle cover is arranged at the upper end of the hanging ring, and a hanging ring inlay block is arranged at the connection of the hanging ring and the hanging ring of the ladle cover, and a light detachable top block is arranged on the inlaying block of the hanging ring. A plurality of lifting lugs are arranged on the body of the ladle cover, one end of the hanging chain is connected with the lower end of the hanging ring, and the other end of the hanging chain is connected with the body of the ladle cover through the lifting lug. The utility model has the advantages of reasonable structure, avoiding hidden dangers such as climbing up, lifting and unloading the ladle cover, ensuring the personal safety of the operator, and automatically completing the replacement of the ladle cover during continuous pouring. A detachable lightweight top block is arranged on the insert block of the hanging ring, so that the hanging chain can not be overlapped during the descending process, and the operator can easily pull straight, thus solving the problem of hanging chain hot-handed, and making the replacement of the ladle cover more convenient.
【技術實現步驟摘要】
一種改進的連鑄鋼水包蓋
本技術涉及煉鋼連續澆注領域,更具體地說是指一種改進的連鑄鋼水包蓋。
技術介紹
鋼水包蓋是通過鋼包加蓋裝置懸于鋼水包上方,可對鋼水包內鋼水起保溫作用的設備。紅坯成型過程中鋼水處于紅熱1200℃狀態,通過設置鋼水包蓋可以對鋼水進行保溫。鋼水在連續澆注過程中,大包回轉臺兩側的大包回轉臂上分別承接兩個鋼水包用于回轉更換澆鑄,這樣可以保證澆鑄的連續性。鋼水包吊裝上大包回轉臺后,由于鋼水包一直處于有鋼水的狀態,因此需要在大包回轉臺上預留鋼水包加蓋裝置,使用鋼水包加蓋裝置將鋼水包蓋吊升到鋼水包上方后再旋轉降落至鋼水包口上,該鋼水包蓋就可對澆鑄過程中的鋼水進行保溫。在鋼水包蓋內嵌有保溫棉以對鋼水包中的鋼水保溫。但是隨著鋼水的翻涌,保溫棉會收縮直至脫落,有時在旋轉過程中鋼水包口邊緣的冷鋼殘渣等也會刮壞保溫棉,因此需要定期更換鋼水包蓋。由于大包回轉臺處于高空,其離P3平臺凈空高為8.6米。在高溫回轉狀態下,需要作業人員爬到高空方便操作的位置,更換鋼水包蓋時存在較大的安全隱患。在更換新鋼水包蓋本體時,掛鏈從吊耳上解下后,掛鏈本身溫度高且會下降疊壓在一起,作業人員在更換拽直時會出現燙手等問題。因此,我們提供一種改進的連鑄鋼水包蓋。
