鋼包回轉臺用軸承

鋼包回轉臺用軸承

       鋼包回轉臺是現(xiàn)代連鑄中應用普遍的運載和承托鋼包進行澆注的設備,通常設置于鋼水接收跨與澆注跨柱列之間。

所設計的鋼包旋轉半徑,使得澆鋼時鋼包水口處于中間包上面的規(guī)定位置。用         鋼水接收跨一側的吊車將鋼包放在回轉臺上,通過回轉臺回轉,使鋼包停在中間包上方供給其鋼水。澆注完的空包則通過回轉臺回轉,再運回鋼水接收跨。

       鋼包回轉臺是連鑄機的關鍵設備之一,起著連接上下兩道工序的重要作用。鋼包回轉臺的回轉情況基本上包括兩側無鋼包、單側有鋼包、兩側有鋼包三種情況,而單個鋼包重量已超過140噸。三種情況下,鋼包回轉臺受力有很大不同,但無論在何種情況下,都要保證鋼包回轉臺的旋轉平穩(wěn),定位準確,起停時要盡可能減小對機械部分的沖擊,為減少中間包液面波動和溫降,要縮短旋轉時間。因此,我們在變頻器的容量選擇上,留有余地,即比電機功率加大一級。同時利用變頻器的s曲線加速功能,通過調整s曲線保證加、減速曲線平滑快速,減少對減速機的沖擊,再通過PLC判斷變速限位、停止限位實現(xiàn)旋轉過程中高、低速自動變換及到位停車,同時滿足了對旋轉時間和平穩(wěn)運行的要求。
