鋼包回轉(zhuǎn)臺用軸承

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

所設(shè)計的鋼包旋轉(zhuǎn)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(cè)的吊車將鋼包放在回轉(zhuǎn)臺上,通過回轉(zhuǎn)臺回轉(zhuǎn),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(zhuǎn)臺回轉(zhuǎn),再運回鋼水接收跨。

       鋼包回轉(zhuǎn)臺是連鑄機的關(guān)鍵設(shè)備之一,起著連接上下兩道工序的重要作用。鋼包回轉(zhuǎn)臺的回轉(zhuǎn)情況基本上包括兩側(cè)無鋼包、單側(cè)有鋼包、兩側(cè)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(zhuǎn)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(zhuǎn)臺的旋轉(zhuǎn)平穩(wěn),定位準(zhǔn)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(zhuǎn)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(diào)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(zhuǎn)過程中高、低速自動變換及到位停車,同時滿足了對旋轉(zhuǎn)時間和平穩(wěn)運行的要求。
